Clamp Types Guide: G-Clamp, F-Clamp, C-Clamp, Quick & Locking Clamps
What is a clamp used for? A clamp applies controlled pressure to hold a workpiece in place while you cut, weld, glue, drill, or measure. The right clamp depends on three things: the shape and size of the workpiece, how much force you need to apply, and whether you need to operate it one-handed. The most common workshop types are G-clamps (heavy general-purpose), F-clamps (long-reach), C-clamps (deep throat), quick-action clamps (one-handed adjustment), and locking pliers (vice grips). F-clamp vs G-clamp — when each is the right pick — Quick Reference Quick reference for clamp types guide, drawn from the detailed section below. Factor G-clamp / C-clamp F-clamp Maximum capacity ~480mm typical workshop range 100mm to 1200mm+ Clamping force Higher (concentrated through stiff frame) Lower (force limited by bar bending under load) Adjustment speed Slower — screw turn for each adjustment Faster — slide the jaw, then short screw turn One-handed use Difficult Possible (especially ratchet F-clamps) Throat depth Fixed by frame design (30-100mm) Varies with bar position Cost per size Cheaper for small sizes (50-200mm) Cheaper for large sizes (250mm+) Best for Heavy fabrication, machinery assembly, holding to bench surface, smaller workpieces requiring high force Larger workpieces, panel work, woodworking glue-ups, situations needing speed over force Why clamps matter — workshop holding without a bench vice everywhere A bench vice holds workpieces at one fixed location. Clamps hold workpieces wherever you need them — on a fabrication table, against an edge, vertically on a panel, across a long workpiece a vice can't reach, or at an angle no vice can manage. The clamp is the workshop's portable, scalable holder. The cost of bad clamping is real. Movement under cut means out-of-square assemblies. Movement under weld means cracked tacks and warped panels. Insufficient force on workhardened or springy metal means the clamp pops off mid-operation. And the wrong clamp for the material — hardened steel jaw on polished aluminium, or oversize G-clamp on thin sheet — damages the surface as fast as no clamping at all. This guide covers the categories most workshops actually need: G/C-clamps (the workshop standard), F-clamps (longer reach, lighter force), locking C-clamp pliers (one-handed), welding specialty clamps (Strong Hand Tools' depth), magnetic and third-hand clamps (welder's hands-free option), and quick-release clamps (one-handed grip-and-release). Pairs nicely with your bench vice, hammer and pliers selection. G-clamp vs C-clamp — the same tool, different names G-clamp and C-clamp are the same tool. AU and UK workshops call it a G-clamp because the frame resembles a capital G. US workshops call it a C-clamp because the frame resembles a capital C. The product is identical — same geometry, same use, same standards. The terminology difference confuses cross-Atlantic buying conversations but it's not a real product distinction. Lowe's (US retailer) is explicit: "The terms C-clamp and G-clamp refer to the same type of clamp, reflecting the shape of the metal frame and the movable jaw assembly." AU vendors split — Bunnings uses G-clamp; Hare & Forbes Machineryhouse uses G-clamp; RS Components AU calls them "G/C Clamps" to cover both. AIMS uses G-clamp throughout as the AU term but stocks them under both labels. What both terms describe: a fixed C/G-shaped frame, a threaded screw passing through one arm with a swivel pad on the end, and a fixed anvil opposite. Tighten the screw to clamp the workpiece between the swivel pad and the anvil. Sizing is described by the clamp's capacity (the maximum jaw opening — typically 50mm to 480mm in AU industrial supply) and throat depth (how far the clamp reaches in from the edge — typically 30mm to 100mm). G-clamp anatomy and sizing — frame, screw, pad, capacity, throat A G-clamp has five working parts and two critical dimensions. Knowing both lets you specify the right clamp for the job. Part What it does What to look for Frame (the "G/C") Resists the clamping load between the screw and the anvil Forged steel (strongest, premium), SG/ductile iron (mid-tier), plain cast iron (budget, brittle) Threaded screw Drives the swivel pad into the workpiece Rolled lead screw thread — smoother action than cut thread; T-handle vs ball-end vs sliding bar handle Swivel pad Distributes clamping force on the workpiece Steel pad (durable, can mark surfaces), ductile/cast pad with swivel joint (better for uneven surfaces) Anvil (fixed jaw) Opposite face the workpiece rests against Should be flat and parallel to the swivel pad at full clamping Handle Tightens and loosens the screw T-handle (most common), sliding bar (heavy-duty), ball-end (precise control) Two critical dimensions to specify: Capacity (jaw opening) — the maximum gap between swivel pad and anvil at fully open. AIMS G-clamps run 75mm at the small end up to 480mm at the heavy-duty end. Match capacity to the thickest workpiece + 25-50mm working margin. Throat depth (reach) — how far the clamp reaches from the edge of the workpiece into the work. Standard throat is 30-50mm; deep-throat G-clamps reach 75-100mm. Critical when clamping in from a flange or panel edge. AIMS G-clamps by size: Trax G Clamp — 75/100/150mm ($17-$27) — light to mid workshop sizing, three capacities Lockjaw 250mm Small Body C-Clamp Swivel Pad Chrome-Moly ($60.96) — premium chrome-moly steel construction Lockjaw 480mm (19") Large C-Clamp Swivel Pad Chrome-Moly ($92.52) — heavy-duty large capacity F-clamps — sliding bar, bigger capacity, lighter force An F-clamp has a sliding bar with two jaws — a fixed jaw at one end, a moving jaw that slides up and down the bar. Tighten the moving jaw's screw to lock it in place against the workpiece. The capacity isn't limited by the frame shape (as with a G-clamp) — F-clamps come in 100mm right up to 1200mm+ capacity. Lower maximum clamping force than a G-clamp of equivalent material, but the longer reach and bigger capacity makes them the choice for larger workpieces. F-clamps are also called "Bessey clamps" colloquially after the dominant German woodworking brand — but Bessey is a brand, not a category. AIMS stocks the Strong Hand Tools F-clamp range; we don't stock Bessey at retail (it's a premium woodworking-focused tier — see scope note below). AIMS F-clamp option: Strong Hand UF100JRM J-Type Ratchet Action Utility Clamp 254mm ($122.64) — workshop F-clamp with ratchet handle for fast adjustment, suits fabrication holding Buying counsel: if you mostly clamp 200mm or under and need strong force (heavy steel fabrication, machinery assembly), G-clamps are the better choice. If you clamp 250mm-1m+ pieces or need fast one-handed adjustment, F-clamps are the better choice. Many workshops keep both. F-clamp vs G-clamp — when each is the right pick Factor G-clamp / C-clamp F-clamp Maximum capacity ~480mm typical workshop range 100mm to 1200mm+ Clamping force Higher (concentrated through stiff frame) Lower (force limited by bar bending under load) Adjustment speed Slower — screw turn for each adjustment Faster — slide the jaw, then short screw turn One-handed use Difficult Possible (especially ratchet F-clamps) Throat depth Fixed by frame design (30-100mm) Varies with bar position Cost per size Cheaper for small sizes (50-200mm) Cheaper for large sizes (250mm+) Best for Heavy fabrication, machinery assembly, holding to bench surface, smaller workpieces requiring high force Larger workpieces, panel work, woodworking glue-ups, situations needing speed over force From r/woodworking (24+ answers): "F-clamps when I need something clamped and Quick-Grips when I don't." The forum consensus is F-clamps for stronger holding, Quick-Grips (one-handed trigger clamps) for fast non-critical holding. Most pro shops run both. Locking C-clamp pliers — Vise-Grip style, hands-free Locking C-clamp pliers combine the geometry of a G/C-clamp with the locking mechanism of locking pliers. Squeeze the handle to clamp — the over-centre toggle locks the jaws closed, freeing both hands. Press the release lever to open. Iconic in welding fabrication where one hand holds the torch and the other manages the work — the locked clamp stays put without continuous attention. The Vise-Grip origin story: "Vise-Grip" is a brand name (originally invented by William Petersen in 1924, now owned by Irwin) that became a generic term for the locking pliers and locking clamp category. AIMS doesn't stock the Irwin Vise-Grip brand at retail — our equivalent is Lockjaw, which is the dominant range in the AIMS clamps collection by inventory volume. From r/Welding (300+ comments thread): "I have Vise Grip brand (original) and Stronghand that have held up for years. My coworker has a few Milwaukee clamps that work great too." Same tier, multiple competing brands. The Lockjaw range at AIMS competes directly with Vise-Grip on capability and pricing. AIMS Lockjaw locking C-clamp range (very high inventory — workshop workhorses): Lockjaw Locking Pliers C-Clamp 230mm + 330mm ($56-$64, 500+215 units in stock) — the standard locking C-clamp pair Lockjaw Locking Clamp with Swivel Head 230mm + 330mm ($56-$68) — swivel pad accommodates uneven surfaces Lockjaw Self-Adjusting Plier C-Clamp Extended Reach 290mm + 455mm ($60-$92) — extended reach for awkward angles Lockjaw 275mm Table C-Clamp Plier with 90mm Jaw Opening ($50.41) — table-mount option for production setups Plus the Excision Xtreme C-Clamp GripLox Plier 250mm + 300mm ($47-$67) as a competing range, and the Trax Locking C-Clamp ($21-$31) at the budget end. Welding clamps — Strong Hand Tools range explained Welding fabrication is the most clamp-intensive workshop activity. Each tack requires the work held precisely and the welder's hands free for the torch and feed. The Strong Hand Tools range at AIMS is built specifically for this — 50+ products covering angle clamping, magnetic positioning, third-hand modular setups, ground clamps, drill press clamps and replacement pads. Strong Hand has copied Bessey's design and runs at lower price points (r/BuyItForLife 12 years ago, r/Welding 180+ comments). Strong Hand welding clamp categories: Table-mount locking C-clamps — Strong Hand PT09 Table Mount Locking C-Clamp 102mm M8 Thread ($61.99). Bolts to the welding table surface, locks the workpiece for repeat positioning. Angle clamping tools (90° corner) — Strong Hand UDL365 Corner Pliers Angle Clamping Tool 90° 50mm ($73.08), 76mm Angle Clamping Tool ($102.31). Perfect right-angle box fabrication — clamp two pieces at 90° in one operation. Saves rework on box welding. Welding finger clamps (Grasshopper-style) — StrongHand 300mm Welding Finger Clamp Grasshopper ($60.90). Long thin clamp reaches into tight spaces panel welding can't otherwise hold. Half clamps and side clamps — Strong Hand VHC15 Half Clamp ($90.89), VSC15 Side Clamp ($83.83). Specialty geometries for awkward welding angles. Grinder rest C-clamps — Strong Hand MGK53 Grinder Rest C-Clamp Base Model ($50.82). Mounts a small grinder securely to the bench for sharpening / dressing work. Drill press clamps — Strong Hand PTD09 Drill Press Clamp ($62.50). Holds the workpiece on the drill press table during drilling — different geometry from a free clamp. For stick welding fabrication and MIG welding shop work, this clamp range is purpose-built. See the Stick Welding Guide and MIG Welding Guide for process context; the clamps are how you keep the work square while welding. Magnetic welding clamps and third-hand setups Magnetic welding clamps eliminate the hand-holding step in tacking operations — the magnet holds the workpiece against the work surface or another magnetic part while the welder positions. Critical for solo welding work where every "third hand" needed is a hand that doesn't exist. AIMS magnetic clamp range: StrongHand MagVise with Adjustable Spindle ($63.50) — magnetic-based vise with adjustable spindle for clamping force control Strong Hand MagVise with Pliers ($52.08) — magnetic base + plier-style clamping head Strong Hand Magnetic Panel Clamp Twin Pack ($34.44) — pair of magnetic panel clamps for double-sided panel positioning Strong Hand Snake Magnet 405mm Cable + Clamp + Flat Magnetic Pad ($52.92) — flexible "snake" arm with magnetic base, ideal for awkward positioning Third-hand modular clamps: for repeat fabrication where the work needs holding at a precise angle or position multiple times, modular third-hand clamps mount to the welding table and hold a workpiece at the configured geometry. Strong Hand HAS40 Welding Table Base Mount Third Hand Modular Clamp ($112.90) bolts to a welding table; HAS42 Universal Base Mount ($96.18) clamps to any flat surface. The "third hand" name comes from the welder's reality — you need a third hand to hold the work while you tack, and this is it. Quick-release / trigger-action clamps Quick-release clamps (also called trigger clamps, one-handed clamps) use a pistol-grip trigger mechanism instead of a screw. Squeeze the trigger to advance the moving jaw; press the release lever to retract. Faster than F-clamps, lower clamping force than G-clamps, ideal for one-handed work where the other hand holds the workpiece. The dominant brand is Irwin Quick-Grip (a brand name that became a generic term for the category, like Vise-Grip). AIMS doesn't stock Irwin Quick-Grip at retail — our equivalent is: Piher 450mm Quick Clamp Trigger Action Nylon & Fibreglass Jaw ($67.87) — Piher is a respected European clamp brand, this is the workshop trigger-action option Abbott & Ashby Workshop Quick Clamp for Bench Vice (2-pack) ($18.68) — budget option, designed to fit Abbott & Ashby bench vices When to choose quick-release over F-clamp: when one-handed operation matters (other hand holding the work, or applying glue, or wiring), and when clamping force ≤ what the trigger mechanism can apply (~150 kg typical). When you need maximum force, go back to G-clamp or screw F-clamp. Construction materials — forged steel vs SG cast iron vs cast iron The frame material determines clamping force capacity, impact resistance and price. Material Tier Properties Best for Drop-forged steel Premium Highest strength; grain flow follows frame shape; impact-resistant; won't crack under shock load. Most expensive. Heavy fabrication, machinery assembly, daily-use industrial Chrome-molybdenum steel (CrMo) Premium Like forged steel but alloyed for higher hardness and wear resistance. Lockjaw's premium C-clamp range uses this. Daily-use industrial workshop, fabrication trade SG cast iron / ductile iron / nodular iron Mid-tier Cast iron with spheroidal graphite — much more impact-resistant than plain cast iron. AU's Hare & Forbes RPC clamps use this. General workshop, occasional industrial Malleable iron Mid-tier Annealed cast iron — improved ductility. Common on AU industrial G-clamps. General workshop Plain cast iron Budget Cheap but brittle — will crack under shock load. Bunnings DIY tier is mostly this. Light occasional use, not industrial production Forum reality (UK Workshop forum, 2006 thread still relevant): "Record clamps are superior in that they are forged steel, not cast iron. Drop forging imparts grain flow in the forging complimentary to its overall shape." Drop-forged steel is the gold standard; SG/ductile iron is the practical workshop tier; plain cast iron is the budget compromise that's fine for light use but fails when overloaded. The Lockjaw chrome-molybdenum steel range at AIMS — 480mm Large C-Clamp Chrome-Moly and 250mm Small Body C-Clamp Chrome-Moly — is the premium-tier material grade for AU workshop buyers who don't want to source Bessey directly. Frame size, throat depth and reach — match the dimensions to the job Two dimensional decisions to get right: Capacity (jaw opening): the maximum gap when fully open. Always buy capacity at least 25-50mm bigger than the thickest workpiece you'll regularly clamp. Don't try to "just fit" — the screw runs out of thread, the swivel pad ends up unsupported, and clamping force drops to nothing. Throat depth (reach): how far the clamp reaches in from the edge. Standard G-clamps: 30-50mm. Deep-throat G-clamps: 75-100mm. F-clamps vary with bar position. For workpieces wider than your standard clamp can reach, you need either deep-throat clamps or F-clamps. Sizing for AU workshops (rules of thumb): Application Capacity needed Recommended AIMS option Light bench fitting, small parts 50-100mm Trax G Clamp 75/100mm General workshop, medium fabrication 150-250mm Lockjaw 250mm Chrome-Moly, Trax G Clamp 150mm Heavy fabrication, large workpieces 300-480mm Lockjaw 480mm Chrome-Moly Long panels, wider than 500mm F-clamp (varies) Strong Hand UF100JRM F-Clamp 254mm Welding tacking, hands-free Match welding clamp to plate thickness See Strong Hand Tools welding range above Drill press operation Drill press-specific Strong Hand PTD09 Drill Press Clamp Workshop counsel: buy a set covering 75-250mm before you buy specialty welding or magnetic clamps. Standard G-clamps in 4 sizes solve 80% of workshop clamping problems. Specialty clamps come later when specific jobs demand them.

The following product categories are better served by Bunnings, Sydney Tools, Total Tools, Trade Tools or specialty woodworking retailers (Carbatec, Timbecon, Carrolls Woodcraft): Woodworking clamp type Use Where to buy Bessey parallel clamps Cabinet making, panel glue-ups — parallel jaws stay flat across the workpiece Carbatec, Timbecon, Total Tools Irwin Quick-Grip woodworking One-handed wood gluing, lighter than F-clamps Bunnings, hardware Pipe clamps (Pony, Jorgensen) Long workpieces — clamping a tabletop or bench top Specialty woodworking Spring clamps Light holding for thin material, hose work, model making Bunnings, craft stores Cabinet hardware clamps Drawer fronts, hinge installation Hardware specialty Sash clamps Door and window frame assembly Carbatec, Timbecon AIMS supply focuses on industrial workshop and fabrication — Lockjaw locking clamps, Strong Hand welding range, Trax workshop tier. For woodworking, see the specialty retailers above. If you have a mixed shop (some metal, some wood), keep the two clamp categories physically separated — woodworking clamps often have wide soft pads that don't grip metal well; metal clamps' steel pads damage finished wood. Common mistakes — 8 forum-validated errors Mistake Why it fails Fix Buying cheap cast iron G-clamps for production Plain cast iron is brittle — cracks under shock load or over-torquing. Frames fail unpredictably. Forged steel for daily use; chrome-moly for premium; SG/ductile iron for general workshop. Avoid plain cast iron in production. Over-tightening G-clamps Bend the frame, crack cast iron, strip the screw threads. The clamp deforms but the user thinks the workpiece is "clamped tight" — false security. Tighten only to the resistance you need. If the workpiece still moves at moderate force, use a larger clamp or two clamps in parallel. Steel swivel pad on polished or soft surfaces Marks the workpiece — paint, polish, aluminium, copper, brass. Damage is permanent. Use a soft pad insert (rubber, plastic), or place a scrap of wood/leather between the pad and the workpiece. Strong Hand sells soft pad inserts for the UB/UD/UE/UF/UG/UM/UP series. Single-clamp setup for fabrication tacking One clamp creates a pivot point — the work rotates around it. Tacks pull the assembly out of square. Two or more clamps minimum for any fabrication tack. Use angle clamping tools (Strong Hand UDL365) for 90° box fabrication. Wrong clamp size for the job Capacity too small = no room to clamp; capacity too big = screw at near-full extension is unsupported and weak. Match capacity to workpiece thickness + 25-50mm margin. Don't try to make a 100mm clamp work on 95mm material. Mismatched welding clamp for plate thickness Magnetic clamps on thin sheet bend the sheet; angle clamps designed for 6mm plate are weak on 25mm plate. Match welding clamp design to plate thickness — Strong Hand product range is sized by capacity and intended fabrication tier. Ignoring jaw geometry for the surface Flat-jaw G-clamps on a curved or angled surface = point loading + slip-off. Swivel pads accommodate uneven surfaces. Use swivel-pad G-clamps for non-flat surfaces (Lockjaw Swivel Head range, Trax with Swivel Pad). No replacement pad strategy Worn pad = reduced clamping force, marked workpieces, eventual screw damage. Workshop ignores until clamp fails. Buy replacement pads as part of initial purchase — Strong Hand replacement pad kits for UB/UD/UE/UF/UG series are cheap insurance. Care and maintenance — preventing seized threads Clamps last years if maintained. Three failure modes dominate: Seized threads — workshop dust, rust and metal swarf accumulate on the lead screw. Eventually the screw won't turn. Lubricate the thread monthly with a light oil (3-in-1, light machine oil). Don't use heavy grease — it traps swarf and accelerates seizing. Worn swivel pads — daily-use clamps wear the pad to a tilted face after months. Replace pads (Strong Hand replacement range, or generic pads from /collections/clamps) before the worn pad damages workpieces. Bent frames — over-tightening or shock load bends a cast iron frame slightly out of square. The clamp still works but doesn't grip parallel. Replace the clamp rather than try to straighten — bent cast iron is weakened. For locking C-clamp pliers (Lockjaw, Strong Hand PT09): occasionally clean the adjustment screw thread with brake cleaner or thread cleaning brush + light oil. The locking mechanism's spring may eventually weaken — replace the clamp rather than the spring. Wear safety glasses when working with clamps — locking-clamp release under unexpected load can fling the work or the clamp itself. Frequently Asked Questions Are G-clamp and C-clamp the same thing? Yes. G-clamp and C-clamp refer to the same tool — the AU/UK term is "G-clamp" (frame resembles a G); the US term is "C-clamp" (frame resembles a C). Same geometry, same use, same product. Lowe's (US retailer) is explicit: "The terms C-clamp and G-clamp refer to the same type of clamp." AU vendors split between the terms — Bunnings uses G-clamp, RS Components calls them "G/C Clamps." AIMS uses G-clamp throughout. What is the difference between an F-clamp and a G-clamp? G-clamps have a fixed C/G-shaped frame with a screw at one end — capacity limited by the frame (typically 50-480mm), force concentrated by the stiff frame. F-clamps have a sliding bar with two jaws — capacity unlimited by frame (100mm to 1200mm+), force lower because the bar bends under load. Choose G-clamp for high-force smaller workpieces; choose F-clamp for larger workpieces and faster adjustment. Most workshops keep both. What is a G-clamp used for? Holding workpieces during machining, welding, drilling, gluing, sawing, sanding and assembly. The G-clamp is the workshop's general-purpose temporary holder — applies controlled pressure to keep parts immobile while the operation runs. Sizes from 50mm (small bench work) to 480mm (heavy fabrication) cover most workshop tasks. Pair G-clamps with a bench vice for the most flexible holding setup. What is an F-clamp used for? Holding longer or wider workpieces than a G-clamp can accommodate — typically panels, frames, long timber, or assemblies that exceed 250mm thickness. F-clamps have a sliding bar that lets the capacity reach 1200mm+, and the moving jaw adjusts faster than a G-clamp screw. Common in woodworking glue-ups, panel fabrication, and heavy assembly. Lower clamping force than equivalent-size G-clamps but bigger reach. What is the difference between a locking C-clamp and a regular C-clamp? A regular C-clamp uses a threaded screw — turn the handle to tighten. A locking C-clamp (often called Vise-Grip C-clamp) uses an over-centre toggle mechanism — squeeze the handles together to clamp, the toggle locks. Both hands are then free. Press the release lever to open. The locking version is much faster for repeat tacking work in welding fabrication. The downside is a lower maximum clamping force than a screw-type G/C-clamp of the same size. AIMS stocks the Lockjaw range as the workshop locking-clamp option. What is the strongest type of clamp? For maximum clamping force per dollar, a drop-forged steel G-clamp wins. For force per setup speed, an F-clamp with screw or ratchet handle is faster. For one-handed locking force, locking C-clamp pliers (Vise-Grip / Lockjaw) hold both hands free. The "strongest" depends on what you're optimising — force, speed, or hands-free locking. A heavy-duty drop-forged 12" G-clamp will deliver 5,000+ kg of clamping force. What is the difference between forged steel and cast iron G-clamps? Drop-forged steel is forged under heat and pressure — the grain flow follows the frame shape, giving maximum strength and impact resistance. SG/ductile/nodular cast iron is cast in moulds, then chemically modified for ductility (less brittle than plain cast iron). Plain cast iron is the cheapest — brittle, will crack under shock load. Forged steel is premium tier (workshop-daily); SG/ductile cast iron is mid-tier (general workshop); plain cast iron is budget (light occasional use). The Lockjaw chrome-molybdenum steel range at AIMS is the premium tier. What clamps do welders use? Welders use specialty welding clamps from the Strong Hand Tools range: angle clamping tools (90° corner pliers, UDL365), locking C-clamps that bolt to the welding table (PT09 Table Mount), magnetic clamps (MagVise, Snake Magnet, Panel Clamps), third-hand modular setups (HAS40, HAS42), grinder rest clamps (MGK53), drill press clamps (PTD09), and Grasshopper-style welding finger clamps (300mm) for tight space holding. The Strong Hand range at AIMS covers all of these. For positioning thin sheet, magnetic clamps eliminate hand-holding completely. What is a magnetic welding clamp? A magnetic welding clamp uses a rare-earth magnet base to hold the clamp body to the workpiece or work surface. The welder positions the workpiece against the magnet, then the clamp's jaw or arm holds the second piece in position — hands-free. Critical for solo welding work where you don't have a third hand. AIMS magnetic clamp options: StrongHand MagVise with Adjustable Spindle, MagVise with Pliers, Snake Magnet 405mm, and Magnetic Panel Clamp Twin Pack. What is a third hand welding clamp? A third hand welding clamp is a modular workholding setup that mounts to the welding table (or any flat surface) and holds the workpiece at a configured angle or position. The "third hand" refers to the welder's reality of needing a third hand to hold the work while you tack — and this is it. Strong Hand HAS40 (welding table base mount) and HAS42 (universal base mount) are the AIMS options. For repeat fabrication where the same piece needs holding at the same angle multiple times, third hand setups save time over re-clamping with G-clamps each cycle. What's the difference between a clamp and a vice? A vice is bench-mounted — bolted to a workbench, fixed location. A clamp is portable — used wherever the work happens. Both hold workpieces under controlled force, but vices are for sustained holding at a fixed station, clamps for temporary/portable holding. Many workshops use both — clamp the work in the vice for the most flexible holding (e.g. clamp a small part to a flat plate, then hold the plate in the vice). See the Bench Vice Guide for vice selection. How do I choose the right size G-clamp? Match capacity (jaw opening) to your workpiece thickness + 25-50mm working margin. A typical workshop set covers 75mm, 100mm, 150mm and 250mm capacities — solving 80% of workshop clamping problems. Heavy fabrication needs larger (300-480mm). For workpieces too wide for any G-clamp, switch to F-clamps. Also consider throat depth (reach from edge) — standard 30-50mm, deep-throat 75-100mm. AIMS G-clamp range covers 75mm (Trax) up to 480mm (Lockjaw Chrome-Moly 480mm). What is a quick-release clamp / Quick-Grip? A quick-release or trigger-action clamp uses a pistol-grip squeeze trigger instead of a screw. Squeeze the trigger to advance the moving jaw; press the release lever to retract. Faster than F-clamps, lower clamping force than G-clamps. Iconic brand: Irwin Quick-Grip (which became a generic name for the category, like Vise-Grip). AIMS doesn't stock Irwin Quick-Grip at retail — our equivalent is the Piher 450mm Quick Clamp Trigger Action and Abbott & Ashby Workshop Quick Clamp 2-Pack. Are Strong Hand Tools clamps as good as Bessey? For welding fabrication: yes, with caveats. Strong Hand Tools has copied many Bessey designs at lower price points — workshop and forum consensus from r/Welding (180+ comments thread) and r/BuyItForLife is that the Strong Hand light-duty welding clamps perform similarly to Bessey at a fraction of the price. For premium woodworking parallel clamps (Bessey's signature product), Strong Hand doesn't compete — Bessey is unmatched there. AIMS stocks Strong Hand because they hit the AU welding-shop sweet spot of capability + price; we don't stock Bessey at retail (their woodworking-dominant range targets a different retail channel). Why does AIMS not stock Bessey or Irwin Quick-Grip woodworking clamps? AIMS is an industrial supply business focused on workshop, fabrication, welding and engineering trades. Bessey's premium parallel clamps and Irwin's Quick-Grip woodworking line are better served by specialty woodworking retailers (Carbatec, Timbecon, Carrolls Woodcraft) and big-box hardware (Bunnings, Total Tools). AIMS dives deep on the industrial clamp range — Lockjaw locking pliers (workshop workhorse), Strong Hand Tools welding specialty (50+ products), Trax workshop tier, Piher quick clamps. If you need Bessey or Irwin specifically, call AIMS on (02) 9773 0122 — we can sometimes source through supplier network. Share: Share on Facebook Share on X Pin on Pinterest Previous Post What clamp do I need for gluing wood? F-clamps and sash clamps are the standard choice for woodworking glue-ups. F-clamps suit panel work and small assemblies where you need quick adjustment across a range of sizes. Sash clamps are long bar clamps designed for cabinet doors, tabletops and panel edge-joining. Use cauls or scrap timber between the clamp jaws and the workpiece to spread pressure and avoid marking the timber. Is a G-clamp the same as a C-clamp? Yes — G-clamp is the Australian and UK name; C-clamp is the American name. Both describe the same tool: a fixed C-shaped frame with a threaded screw and swivel pad that closes onto the workpiece. They are used interchangeably across welding, metalwork, machining and woodworking, with sizes typically ranging from 50mm to 300mm jaw opening. What's the difference between a clamp and a vice? A clamp is a portable tool you place onto a workpiece to hold parts together temporarily. A vice is a fixed device mounted to a bench or stand that holds a workpiece stationary while you work on it. Clamps come off when the job is done; vices are permanent workshop fixtures. Both apply pressure through a screw mechanism, but they serve different roles. Can I use a clamp instead of welding to hold pipes? Pipe clamps and U-bolts can hold pipes mechanically for support, fixing to structures, or temporary alignment during fit-up. They are not a substitute for welding when the joint needs to be sealed or carry load. For permanent gas, water, hydraulic or structural pipework, use the correct fitting or welded joint. Use clamps to align and tack during fit-up, then remove once the joint is finalised.

Hammer Types Guide: Ball Pein, Dead Blow, Soft Face & Sledge Selection for Engineering & Workshop
Hammers look simple. They are not. The hammer you reach for changes the outcome of the strike — a claw hammer on a metal chisel rounds the chisel and chips the hammer face; a steel hammer on a precision-machined dowel pin mushrooms the pin; a thin TIG glove's worth of dexterity isn't worth keeping if a hard-face hammer cracks the part you're trying to assemble. This guide is the engineering and workshop hammer reference — ball pein, dead blow, soft face (Thor system explained), sledge, drilling and chipping hammers. AIMS stocks the engineering range deeply (Thor, Nupla, Stahlwille, Bossweld, Trax pneumatic) but not carpentry hammers (claw, framing, brick) — those are covered briefly with an honest "see other retailers" note. Use the right hammer; protect the work. The three pein hammer types are ball pein, cross pein, and straight pein. The ball pein has a rounded peen used for shaping rivets and metal forming, and is the most common engineer's hammer in Australian workshops. The cross pein has a wedge-shaped peen at right angles to the handle for starting nails between the fingers. The straight pein has the wedge in line with the handle for shaping in tight spots. All three are general-purpose engineer's hammers in 100 g to 1.5 kg head weights. Pein Hammer Types — Quick Reference Type Peen shape Used for Ball pein Rounded ball, opposite the flat face Shaping rivets, peening metal, general workshop Cross pein Wedge, perpendicular to the handle Starting nails, light forging across the grain Straight pein Wedge, in line with the handle Forging along the grain, tight-access shaping Engineer's hammers all share a hardened steel face. For non-marring work, see the dead blow, soft face (Thor copper / rawhide / nylon) and rubber mallet sections below. Why hammer choice matters — strike the right way Workshop hand injuries from hammers fall into two big categories: missed strikes (struck thumb, struck workpiece edge) and recoil/shock injuries (wrist strain, elbow tendinitis from daily-use mismatched hammers). The wrong hammer doesn't just damage the work — it damages the user over time. Wood handles transmit shock through the wrist; fibreglass and aluminium dampen it. Hardwood-handle sledge hammers on cold steel chisels split handles routinely; dead-blow hammers eliminate the rebound that drives most strain injuries. The other failure pattern is using the wrong face material for the workpiece: a hardened steel face on a precision-ground surface either marks or deforms it. A soft-face hammer (rawhide, copper, plastic, nylon) prevents marking but won't deliver the strike force needed to drive a hardened cold chisel. Three hammers minimum cover most workshop jobs — ball pein for steel work, dead blow for assembly, and a soft-face for precision parts. This guide assumes you already have PPE sorted: safety glasses (essential — chipped hammer faces and struck steel send fragments), hearing protection for sustained hammer work in confined spaces, and work gloves for grip and cushioning. PPE doesn't replace the right hammer choice — it complements it. Driving hammers vs soft-face hammers — the two big categories Every hammer in this guide falls into one of two functional categories. Driving hammers have hardened steel faces and deliver maximum force into the workpiece — ball pein, sledge, drilling, claw. Soft-face hammers have replaceable or fixed soft faces (rubber, plastic, nylon, copper, rawhide, lead) and protect the workpiece from marking — Thor, Nupla soft-face, Stahlwille plastic. Pick the category first, then narrow on face material and weight. Category Face Job Typical weight Best for Driving hammers (hardened steel face) Drop-forged carbon steel, case-hardened Maximum strike force into the work 16oz–20lb (450g–9kg) Striking chisels and punches, driving pins, hot-work peening, demolition, sledge work Soft-face hammers (replaceable or fixed soft face) Rawhide, plastic, nylon, copper, rubber, lead — interchangeable on Thor and Stahlwille Strike without marking the workpiece 4oz–7lb (110g–3.2kg) Assembly, fitting, machining, precision dowel/pin driving, automotive panel work A handful of hammers cross the line — a dead-blow hammer uses a shot-filled head inside a hard plastic or rubber outer shell, so it delivers driving-hammer force without driving-hammer rebound. We'll cover dead blow in its own section. AIMS dives deep on the engineering side of both categories: Thor for the soft-face range (15+ active models including the workshop-standard Thor Rawhide Face hammer and the premium Thor Rawhide Size 4 (2000g)), Nupla for driving hammers (Nupla Ball Pein, Nupla Drilling Hammer, Nupla Sledge 20lb), Bossweld for chipping, Stahlwille for premium plastic-face, and Trax for pneumatic air hammers. What we don't stock: claw hammers, framing hammers, brick/mason hammers — see the "carpentry hammers" section below for the honest scope. Ball pein hammers — the workshop generalist A ball pein hammer (UK and AU spelling) — also called ball peen hammer (US spelling, same tool) — is the engineering shop's general-purpose hammer. It has two ends: a flat striking face for driving chisels, punches and steel pins, and a rounded "ball pein" on the opposite end for peening work (shaping rivet heads, drawing curves in sheet metal, work-hardening). Most workshop traditions teach the ball pein before any other hammer. What makes a ball pein different from a claw hammer: the face is harder. Ball pein hammers are case-hardened steel — the outer surface is tough, the inside softer for shock absorption. This lets the face strike hardened cold chisels and steel punches without rolling or chipping. A claw hammer's face is softer (designed for nail driving into wood) and will deform if used on hardened steel — and worse, can chip and send hardened fragments flying. Quoting r/Tools (240+ comments thread): "A ball peen is my go-to, general purpose hammer. I never use a claw hammer for anything else other than driving nails into wood." Typical sizes: 8oz for fine work and engraving; 12oz–16oz for general bench fitting; 24oz for general workshop and metal forming; 32oz–48oz for heavy fitting and rivet work. The Nupla Ball Pein Hammer (rubber grip) at AIMS is the workshop standard — drop-forged head with fibreglass handle and rubber grip for shock absorption. The "pein" end uses: Peening rivet heads — strike the ball end repeatedly around the rivet stem to mushroom the head and lock the rivet (still common in trailer building, restoration, aircraft sheet metal) Drawing curves in sheet metal — controlled strikes shape a panel without marking the show surface Work-hardening edges — repeated peening strikes increase surface hardness on softer metals Stretching metal — peening expands the struck zone, useful in metal forming and panel beating The flat-face end uses: Striking cold chisels and bolster chisels — the harder face matches the hardened chisel Driving pins, punches and drift pins — hardened tool steel strike on hardened tool steel Light demolition with a chisel — controlled chipping of concrete, mortar, weld slag Driving nails when no carpentry hammer is to hand — works, but the heavier head fatigues the wrist faster Forum-validated weight rule: a 24oz ball pein is "very heavy for anything other than serious workshop and metal forming. 16oz for general bench, 12oz for fine work" (r/Tools 100+ comments). Pick the lightest weight that still delivers the strike force you need. Cross pein, straight pein and the pein variations The "pein" of a hammer is the back end opposite the flat face — the shaped end designed for specialised metalwork tasks. Ball pein is the most common in AU workshops but two variants exist: Cross pein — wedge-shaped pein at 90 degrees to the handle. Used for starting small nails (the wedge end positioned between fingers to hold the nail), striking curves in sheet metal in a linear direction, and traditional metalworking technique. Less common in AU industrial supply than ball pein. Straight pein — wedge-shaped pein aligned with the handle. Similar uses to cross pein but the wedge runs lengthwise. Mostly historical / specialist blacksmith use. Ball pein — rounded pein for peening, drawing curves, work-hardening rivets. The AU/UK standard. For most AU engineering work, ball pein is the right pick. AIMS stocks ball pein; cross-pein and straight-pein are sourced through supplier network on request. Call (02) 9773 0122 for specialty pein requirements. Dead blow hammers — strike without rebound A dead blow hammer has a hollow head filled with steel shot or sand, encased in a hard rubber or plastic outer shell. The shot moves on impact — absorbing the rebound that would otherwise bounce a normal hammer back at your wrist — so the full strike energy transfers into the workpiece. No rebound, no missed second strike, no shock back through the handle. Dead blow is the workshop's go-to for assembly, automotive panel work, and anywhere a precision part needs persuasion without marking. Why dead blow matters (forum-validated, r/harborfreight 130+ comments, Garage Journal): "There is no real recoil and you get a lot more impact force with a dead blow." "Dead blow ball peens are a lot better on the arms and wrist. You can have all that after-shock with those wooden handles." Steel caps prevent the outer shell from being destroyed quickly The shot-filled head means the same strike force into the work without the same wrist strain AIMS dead blow range: Nupla Dead Blow Hammer 1350g / 3lb — $194.90. Premium fibreglass handle, full Nupla construction. The heavy assembly hammer for serious shop use. Thor Dead-Blow Hammer (White Nylon Face, Aluminium Handle) — $91.55. Lighter weight, premium Thor build with vibration-dampening aluminium handle. Common applications: driving precision dowel pins into housings, seating bearings into bores (paired with a bearing installation kit for press-fit work), tapping panel beats, assembling automotive parts, persuading misaligned components. Combined with light keyway and shaft work, dead blow is the assembly hammer. When NOT to use dead blow: striking hardened cold chisels (use ball pein — the soft outer shell of a dead blow will deform against the chisel handle), driving wedges into wood (use a sledge or club hammer — dead blow energy disperses before fully driving the wedge), peening rivets (use a ball pein — dead blow can't shape the rivet head). Soft-face hammers — the Thor system explained Soft-face hammers are the workshop's precision-assembly tool. They strike without marking the workpiece — critical for machined surfaces, polished panels, copper-plated work, plastic and aluminium parts. The Thor system (a UK premium brand AIMS stocks deeply) defines the soft-face category in AU industrial supply: a hammer head bored to accept replaceable threaded inserts of different materials, sized 38mm or 50mm face diameter. The five Thor face materials, ordered by softness: Face material Softness Best for AIMS product Rawhide Softest — won't mark even soft brass or copper Finest assembly, jewellery, polished surfaces, fitting precision parts Thor Rawhide Face Plastic (Thorex) Soft-medium — replaceable Thorex inserts (orange) General assembly, panel work, light machining Thor Thorex Plastic 650g Nylon Medium — harder than rawhide, more durable than plastic Heavier assembly, light dolly work, panel beating Thor Nylon Face Copper Medium-firm — won't mark steel parts but soft enough to absorb the strike Steel pin driving, machinery assembly, machining shop standard Thor Copper Hammer Face Aluminium Firmest soft-face option — harder than copper but still won't mark steel Heavy pin driving where copper deforms too quickly Replacement face — sourced Why "soft-face hammer" is a workshop term, not a single product: the soft-face concept covers any hammer designed to strike without marking. The Thor system is the most flexible — buy the head and handle once, swap faces as they wear or as the job changes. The Thor Rawhide Size 4 (2000g, fibreglass handle) and Thor Copper Size 4 (2930g, fibreglass handle) are the premium heavy-duty options at AIMS — both 50mm face diameter, both ~$265-$269. Why machinists use brass and copper hammers (r/interestingasfuck 460+ comments, r/Machinists workshop threads): "In machining we use brass hammers so we don't damage parts." Copper and brass are softer than the hardened steel of precision machined parts, so the hammer absorbs the strike — the part doesn't deform. Critical for tolerance-critical work where a millimetre's mark on a precision dowel pin is a scrap-out. Stahlwille — the premium German alternative: the Stahlwille Plastic Hammer with Interchangeable Head ($35.70) is the premium German engineering alternative to Thor. Same replaceable-face concept, different brand heritage. Common in European-spec machinery workshops. Chipping hammers — for welding slag removal Chipping hammers are the welder's slag-removal tool. After a stick weld or flux-cored MIG weld, slag covers the bead and must be chipped away before inspection or further welding. A chipping hammer has a pointed end (for breaking slag at the weld toe) and a chisel end (for sweeping the slag clear). They're a specialty tool, sized small (typically 400g–500g) for one-handed use over the welding helmet's fume zone. AIMS chipping hammer range: Bossweld Chipper Professional Chipping Hammer 400g — $21.32. Workshop standard chipping hammer with cone/chisel ends and conventional handle. Bossweld Spring Handle Chipping Hammer — $9.35. Budget spring-handle version. The coiled-wire handle absorbs shock and lets the user maintain grip through repeated strikes. Pair with safety glasses (essential — slag fragments fly), gloves and a welding chipping brush. For stick welding technique that requires good slag removal, see the Stick Welding Guide; for MIG welding with flux-cored wires (also producing slag), see the MIG Welding Guide. Sledge hammers — heavy demolition and driving Sledge hammers are the workshop's biggest hand-driven impact tool. Weights range 2lb–20lb (900g–9kg), with longer handles for two-handed swing on the heavier weights. Common applications: driving heavy stakes and posts, breaking concrete and masonry (the "sledge" of demolition work), driving heavy wedges for shaft work, persuading stuck machinery components, and any job where mass × velocity is the answer. AIMS sledge hammer: Nupla Sledge Hammer 8.96kg / 20lb — $579.13. The heaviest in the AIMS range. Nupla fibreglass handle (unbreakable under normal use), drop-forged steel head. Inventory typically 10 units — niche product. The 20lb sledge is for demolition, post driving, and very heavy work; not a one-handed tool. For lighter sledge work (4lb–8lb range), AIMS supply is currently thin — the Grip range was discontinued (vendor cancellation). For 4lb–10lb sledge hammers, the supplier network can source — call (02) 9773 0122. Common AU brands in this weight range include Estwing, Stanley, Vaughan and Hultafors (none currently stocked by AIMS). Replacement parts: the Nupla Sledge Hammer Handle ($91.44) and the Nupla Epoxy Kits ($27.27) let you replace a broken or loose handle without binning the whole tool. The epoxy kit is the workshop standard for re-bedding a Nupla head onto a replacement handle — same approach for ball pein and drilling hammers in the Nupla range. Club, drilling and engineer's hammers — the short-handled striker A drilling hammer (also called a club hammer, lump hammer, or engineer's hammer) is a short-handled 2–4lb hammer used one-handed for striking masonry chisels and bolster chisels, light demolition, and bench fitting where a full ball pein would be unwieldy. The short handle (~250mm) gives precise control; the heavy head (1.5–2kg) delivers enough force to drive a cold chisel through stone or steel. AIMS supply: Nupla Drilling Hammer — $138.47, inventory 182 (strong stock). Fibreglass handle, drop-forged steel head. The AIMS workshop standard for chisel work. The drilling hammer fills the gap between a ball pein (too long-handled for confined chisel work) and a sledge (too heavy for one-handed precision). Most fitting and maintenance trades carry one alongside a ball pein. Common applications: striking bolster chisels for masonry, cold chisel work in confined spaces, light demolition, driving small spikes, freeing stuck pins. Carpentry hammers — honest scope (AIMS doesn't stock) Claw hammers, framing hammers, brick hammers, roofing hammers, drywall hammers and tack hammers are the carpentry and construction side of the hammer market. AIMS does not stock these. Our engineering supply focus means we don't carry the Estwing, Stanley, Stiletto, Martinez, Vaughan or Hultafors lines that dominate the AU carpentry market — they're better-served by Bunnings, Sydney Tools, Total Tools, Trade Tools and similar retailers. Carpentry hammer Job AIMS stock? Claw hammer (16oz–20oz) Nail driving and pulling for general carpentry ❌ Bunnings, Sydney Tools, Total Tools Framing hammer (20oz–28oz) Heavy timber framing, waffle face for grip on big nails ❌ Trade Tools, Sydney Tools Brick / mason hammer Chisel end + flat face for masonry work, brick splitting ❌ Bunnings, hardware Roofing hammer / shingle hatchet Hatchet end + nail-driving face for shingle work ❌ Roofing supply Drywall hammer Convex face for dimpling drywall + hatchet end for cutting ❌ Plaster supply Tack hammer (4oz–8oz) Magnetic face for upholstery and panel tack driving ❌ Specialty supply If your job is mixed engineering and carpentry — fitter who also frames the workshop walls, for example — buy carpentry hammers from a hardware retailer and keep them separate from the engineering tools. A claw hammer used on a steel chisel is one of the most common workshop tool-destruction events; keep the two categories clearly identified. Handle materials — wood, fibreglass, steel, aluminium The handle determines shock transmission, durability, weight, and cost. Four materials dominate, each with distinct trade-offs. Material Shock transmission Durability Weight Cost Best for Hickory (wood) High — transmits more shock to wrist Replaceable; can break if mis-struck on the handle Light Cheapest Traditional feel; replaceable; lighter weight ball pein and soft-face Fibreglass Medium — better dampening than wood Very high — won't break under normal use Medium Mid Industrial workshop default — Nupla and Thor heavy range use it Aluminium Low — best wrist dampening High; won't snap but can bend on extreme strike Light Premium Premium dead-blow and soft-face for daily-use; Thor Dead-Blow uses it Steel (one-piece) Highest — full shock transmission Highest — virtually indestructible Heaviest Premium Demolition; tradies; some Estwing carpentry hammers Forum-validated wrist-strain reality (r/Machinists "best hammers that reduce strain on my wrists"): daily-use machinist hammers should have shock-dampening handles — wood is OK for occasional use, but fibreglass and aluminium reduce repetitive-strain injuries (RSI) over time. The Thor Dead-Blow with aluminium handle and the Nupla Ball Pein with rubber grip both address this directly. What goes wrong with wood handles: mis-strikes hit the handle, not the head — wood splinters and eventually splits. The Nupla Sledge Hammer Handle + Nupla Epoxy Kits let you re-fit a Nupla head to a fresh handle, so a $580 sledge isn't binned because a $90 handle broke. Hammer weight selection — match weight to the job Heavier doesn't mean better. The right weight is the lightest hammer that delivers the strike force for the job, because everything heavier costs you in fatigue, wrist strain and reduced control. The forum-validated three-hammer minimum (YouTube Flat Rate Master, Garage Journal): a large ball pein (48oz / ~1350g), a dead blow (45oz / ~1280g) and a brass or copper hammer (24-32oz / 680-900g) covers the engineering workshop spectrum. Application Recommended weight AIMS option Fine engraving, jewellery, model work 4–8oz (110–230g) Small ball pein — sourced Bench fitting, general light work 12–16oz (340–450g) Light ball pein, Thor 650g Thorex General workshop, metal forming, light demolition 24oz (680g) Nupla Ball Pein Heavy fitting, assembly 32–48oz (900–1350g) Nupla Dead Blow 1350g, Thor Rawhide 2000g Heavy assembly, dolly work 3–7lb (1.3–3.2kg) Thor Rawhide Size 4 (2000g), Thor Copper Size 4 (2930g) Drilling / club hammer (chisels) 2–4lb (900g–1800g) Nupla Drilling Hammer Sledge / demolition 4–20lb (1.8–9kg) Nupla Sledge 20lb Buying counsel: err lighter rather than heavier for your first hammer in any category. You can always swing a 16oz ball pein harder if you need to; you can't make a 32oz hammer lighter when your wrist starts complaining at hour three. Replaceable-face systems — when they pay off Premium soft-face hammers — Thor, Stahlwille, Nupla soft-face — use threaded replaceable faces. The head is bored and tapped; faces screw in and out. When a face wears (rawhide deforms; plastic mushrooms; copper rounds), you replace the $5–$25 face rather than buying a new hammer. Replacement face economics: Replacement face Price Whole hammer replacement Break-even Thor Rawhide Face $24.25 $127.23 Replace face every ~6 months vs full hammer every ~2 years = saves $80+ per cycle Thor Copper Face $25.13 $54.94 One face replacement saves $30+ Thor White Nylon Face $16.47 $48.52 One face replacement saves $32+ Nupla Soft Face Yellow Tip $167.41 Buy the head — replace tip annually Premium yellow-grade soft face for heavy industrial assembly When the system pays off: daily-use workshop where the hammer sees multiple jobs a day across different face needs. The Thor system means one head + handle + 3-4 different faces (rawhide, copper, nylon, plastic) covers 90% of engineering assembly work. Long-term economy beats buying four separate hammers. When it doesn't pay off: occasional use where a single fixed-face hammer lasts years. The Thor Thorex Plastic Hammer with Wood Handle at $40.27 is the budget option that fits this scenario. Pneumatic air hammers — the adjacent category Pneumatic air hammers (also called air chisels, air palm hammers) are powered tools, not hand hammers. They replace repetitive hammer-and-chisel work with a compressed-air-driven reciprocating action: rust removal, sheet metal cutting, panel beating, body work, exhaust separation. AIMS stocks the Trax range for industrial pneumatic work. Trax ARX-715H 11mm Hex Shank Long Air Chisel Hammer — $128.10. Standard workshop air chisel, hex-shank chisels. Trax ARX-515 1/4"PT Air Palm Hammer — $256.90. Palm-grip pneumatic hammer for panel work and assembly. Trax Slide Hammer Puller Set, 13pc — $193.20. Dent puller / slide hammer set for panel beating and bearing removal. Air hammers require a compressor — see our companion guide on air supply via the AIMS pneumatic tools collection. Pneumatic chisels and slide hammers are different audiences from hand hammers (automotive panel work, demolition, sheet metal); included here for completeness, not deep-dived.

Common mistakes — 8 forum-validated errors Mistake Why it fails Fix Using a claw hammer on a metal chisel Claw hammer face is softer (designed for nails). Strikes on hardened chisel either chip the hammer face (sending fragments at speed) or roll the chisel head. Use a ball pein for chisel work. Keep carpentry and engineering hammers physically separated in the workshop. Using a hardened steel hammer on machined surfaces Marks, deforms or cracks the workpiece. Common scrap-out on tolerance-critical machinery assembly. Use a soft-face hammer (Thor copper / nylon / rawhide). The whole point of soft-face is preventing this damage. Buying too heavy a hammer "for power" Heavier weight = more wrist fatigue, less control, and eventual RSI. A 32oz ball pein swung 200 times a day causes injuries a 24oz wouldn't. Buy the lightest weight that gets the job done. Up-size only when light hammer falls short of strike force. Striking with the side of the hammer face (the "cheek") The cheek isn't hardened — strikes there can chip the hammer head and send fragments flying. Also damages the workpiece angle. Strike with the centre of the face. Adjust your stance to align hammer-to-target. Ignoring loose handles A loose head + handle on a ball pein or sledge will fly off mid-swing — a serious workshop injury risk. Check the wedge / pin / epoxy bond before each heavy use. Re-bed with epoxy or replace if the handle is loose. Wood handle mis-strikes hitting the handle Wood splinters where the head meets the handle, weakening the bond. A wood handle abused this way breaks unpredictably. Practice strike form; use fibreglass for heavy daily-use. Replace worn wood handles before they fail. One-hammer-fits-all approach Trying to use a single hammer for everything either damages workpieces (soft-face needed for assembly) or under-performs (need a ball pein for chisel work). Build the three-hammer minimum: ball pein + dead blow + soft-face. Add specialty hammers as job range expands. Striking without safety glasses Chipped hammer faces, struck steel and broken chisel fragments fly at face level. Eye injuries are the #1 hammer-related workshop injury. Wear safety glasses for every hammer task. AS/NZS 1337 standard minimum. Hit harder. Hit smarter. Shop Thor, Nupla & Stahlwille hammers at AIMS Industrial From Thor soft-face and rawhide hammers to Nupla ball pein, sledge, and drilling hammers — AIMS Industrial stocks the engineering and workshop hammer range trusted by Australian tradespeople, ready to ship Australia-wide. Browse hammers Talk to a specialist Frequently Asked Questions What is a ball pein hammer used for? A ball pein hammer is the engineering shop's general-purpose hammer. It has a hardened flat face for striking cold chisels, punches, drift pins and steel pins, and a rounded "ball pein" on the opposite end for peening rivet heads, drawing curves in sheet metal, and work-hardening metal edges. Standard workshop weight is 24oz (680g); 16oz for lighter bench work, 32oz–48oz for heavy fitting and rivet work. The Nupla Ball Pein Hammer with rubber grip and fibreglass handle is the AIMS workshop standard. What's the difference between a ball pein and a claw hammer? Ball pein is case-hardened steel — designed to strike hardened cold chisels and steel punches without rolling or chipping. Claw hammer face is softer steel — designed for driving nails into wood. Using a claw hammer on a metal chisel can chip the hammer face (sending fragments at speed) and roll the chisel head. Using a ball pein for nail driving works but is heavier than needed. Keep them separate in the workshop: ball pein for engineering and metalwork, claw for carpentry. What is the difference between "ball pein" and "ball peen"? Same tool, different spelling. "Ball pein" is the UK and Australian spelling; "ball peen" is the US spelling. Google now treats them as equivalent search terms ("Including results for ball peen…"). Both refer to a hammer with a rounded peen opposite the flat face. AIMS uses "ball pein" but supply both spelling variants in product descriptions so AU and US-trained workshop staff can find the same product. What is a dead blow hammer used for? A dead blow hammer is the workshop's go-to for assembly work where you need driving-hammer force without driving-hammer rebound. The hollow head is filled with steel shot or sand — when you strike, the shot moves on impact, absorbing the rebound that would otherwise bounce the hammer back at your wrist. The full strike energy transfers into the workpiece. Common applications: driving precision dowel pins into housings, seating bearings into bores, panel beating, automotive assembly, persuading misaligned components. The Nupla Dead Blow 1350g (heavy assembly) and Thor Dead-Blow with aluminium handle (lighter daily-use) are the AIMS options. What's the difference between a hammer and a mallet? The terms overlap. Generally: a hammer has a hardened steel face designed for high-force impact (ball pein, sledge, claw, drilling); a mallet has a soft-face head (wood, rubber, plastic, rawhide) designed to strike without marking the workpiece. Most "mallets" are technically soft-face hammers, and the Thor and Stahlwille soft-face products are commonly called mallets in workshop conversation. The terminology isn't precise — focus on face material and intended use rather than the label. Why do machinists use copper or brass hammers? Copper and brass are softer than the hardened steel of precision-machined parts — so when you strike a dowel pin, key or component with a copper hammer, the hammer absorbs the strike and deforms slightly, not the part. Critical for tolerance-critical work where a mark on a precision pin is a scrap-out. From r/interestingasfuck (460+ comments): "In machining we use brass hammers so we don't damage parts." Thor copper hammers (Size 4 2930g for heavy work, Copper Face Wood Handle for general workshop) are the AIMS options. What is a soft-face hammer? A soft-face hammer has a head designed to strike without marking the workpiece. The face material is softer than hardened steel: rawhide, plastic, nylon, copper, rubber, or lead. Premium soft-face hammers (Thor, Stahlwille, Nupla) use threaded replaceable faces — buy the head and handle once, swap face material as the job changes. Soft-face hammers are essential for assembly work, machined surfaces, precision parts, and automotive panel work. Wood vs fibreglass vs steel handle — which is best? Depends on use intensity. Wood (typically hickory) is cheapest, has the traditional feel, and is replaceable when broken — but transmits more shock to the wrist and breaks if mis-struck on the handle itself. Fibreglass is the industrial workshop default — very high durability, medium shock dampening, mid-priced. Aluminium gives the best wrist dampening (premium dead-blow handles use it). One-piece steel is virtually indestructible but transmits maximum shock — common on Estwing carpentry hammers, less on engineering hammers. For daily-use workshop work, fibreglass or aluminium reduce repetitive-strain injury risk over time compared to wood. What weight ball pein hammer should I buy? For general workshop use, 24oz (680g) is the AU standard — heavy enough for chisel work and metal forming, light enough for sustained use without wrist fatigue. For lighter bench fitting and finer work, 12oz–16oz. For heavy fitting, rivet work and metal forming, 32oz–48oz. Buy the lightest weight that delivers your typical strike force — you can swing a 24oz harder if you need to, but you can't make a 48oz lighter when your wrist starts complaining. The Nupla Ball Pein Hammer at AIMS is the workshop-standard sizing. What is a Thor hammer used for? "Thor" is a premium UK brand of soft-face hammers — not the Marvel character. Thor hammers use a threaded replaceable-face system, with the head and handle bought once and faces (rawhide, copper, plastic, nylon, aluminium) swapped as the job demands. Common workshop applications: assembly of precision-machined parts, dowel pin driving, panel beating, fitting work, and any task where striking force is needed without marking the workpiece. AIMS stocks 15+ Thor models including the workshop-standard Rawhide Face hammer and the premium heavy Rawhide Size 4 (2000g, fibreglass handle). What is a chipping hammer for? A chipping hammer is a welder's tool for removing slag from stick welds and flux-cored MIG welds. It has a pointed end (for breaking slag at the weld toe) and a chisel end (for sweeping slag clear). Typical weight 400g–500g, designed for one-handed use over the welding helmet's fume zone. The Bossweld Chipper Professional 400g and Bossweld Spring Handle Chipping Hammer are the AIMS options. Essential for stick welding work — slag must be removed before inspection or further passes. What is a club hammer or drilling hammer? Same tool, different names — also called a lump hammer or engineer's hammer. Short-handled (~250mm), 2–4lb (900g–1800g), used one-handed for striking masonry chisels and bolster chisels, light demolition, and bench fitting where a full ball pein would be unwieldy. Fills the gap between ball pein (too long-handled for confined chisel work) and sledge (too heavy for one-handed precision). The Nupla Drilling Hammer is the AIMS workshop standard for cold chisel work and confined-space striking. Can I use a regular hammer on a chisel? A ball pein hammer yes — that's exactly what they're designed for. A claw hammer no — claw hammer face is softer steel designed for nails and can chip when striking a hardened chisel. Chipped hammer faces send fragments flying at face level (eye injury risk) and damage the chisel head. For all chisel and punch work, use a ball pein hammer or a drilling hammer. Always wear safety glasses regardless of which hammer. How do I prevent wrist strain when hammering? Three factors: (1) right hammer weight — too heavy causes RSI over time, pick the lightest that does the job; (2) handle material — fibreglass and aluminium dampen shock better than wood, critical for daily-use; (3) dead-blow hammers eliminate rebound, which is the main cause of wrist strain. The Thor Dead-Blow with aluminium handle and the Nupla Ball Pein with rubber grip address shock-transmission directly. Forum-validated reality (r/Machinists): wrist strain is a real injury concern for daily-use hammer work — handle material and weight choice matter as much as hammer type. Why does AIMS not stock claw hammers? AIMS is an industrial supply business focused on engineering, workshop, fitting, machining and maintenance trades. Claw hammers, framing hammers, brick hammers and other carpentry hammers are better-served by Bunnings, Sydney Tools, Total Tools, Trade Tools and similar retailers — they stock the Estwing, Stanley, Stiletto, Martinez and Vaughan brands that dominate the AU carpentry market. AIMS dives deep on the engineering range (Thor soft-face, Nupla workshop, Bossweld chipping, Stahlwille premium, Trax pneumatic) instead. If you need a specific carpentry brand we don't stock, call us on (02) 9773 0122 — we can sometimes source through supplier network.

Looking for bossweld? Our bossweld range covers the common sizes and brands. For vibration resistant gloves, see our vibration resistant gloves range stocked across Australia. Welding gloves are arguably the most-replaced item of welding PPE — and the most often badly chosen. The wrong glove either fails (burn-through, seam split, melted lining) or actively works against you (loss of dexterity on TIG, restricted feed-hand mobility on MIG, premature fatigue on long jobs). This guide cuts through the confusion: TIG vs MIG vs stick gloves, the six leather grades that actually matter, what AS/NZS 2161.4 markings mean, cuff length, sizing, and the Bossweld + Frontier + BossSafe range we stock at AIMS. Scope: industrial welding hand protection (TIG, MIG, stick, plasma, oxy/acetylene, foundry, forge). Not for consumer grilling, oven mitts, or garden work — those require different (and usually cheaper) products. Why welding gloves matter — the injury reality Welding hand injuries are dominated by three mechanisms: contact heat (touching a hot workpiece, dropped electrode, slag splash), radiant heat (UV and IR from the arc), and mechanical impact/abrasion (hot spatter, sharp edges, falling stock). The arc itself runs at 1,100–6,000°C depending on process. Even a short bare-skin exposure to the arc's UV will produce a sunburn-equivalent injury within seconds — and that's just the radiation, before any actual contact with metal. Welding glove failures are usually slow rather than dramatic: seams open up over weeks of use, fleece linings collapse and stop insulating, surface leather hardens and cracks. The result is a glove that looks intact but no longer protects to its rated level. Replacement intervals matter — most workshops budget 1–3 months for daily-use leather welding gloves, less for high-spatter MIG/stick work. This guide assumes you already have eye protection, helmet, respirator, jacket and safety boots sorted. If not, see our companion guides on welding helmets, welding eye protection, the respirator guide for fume control, and safety boots. Hand protection without those is a partial solution. The four glove categories: TIG, MIG, stick, and heat-resistant general Welding gloves split into four functional categories. Picking the wrong category is the most common mistake we see at the counter — a TIG glove on stick work, or a thick MIG gauntlet for fine pipe TIG, both fail in predictable ways. Category Process Priority Typical leather Cuff length Lining TIG TIG (GTAW), light brazing, fine pipe work Dexterity + tactile feedback Goatskin, deerskin (premium), pigskin Short to medium (28–36cm) Unlined or thin cotton MIG MIG (GMAW), flux-cored, light stick Heat + spatter balance Cowhide top-grain, pigskin, split cowhide Medium to long (35–40cm) Cotton or fleece Stick Stick (SMAW/MMA), heavy MIG, foundry adjacent Maximum heat + abrasion Split cowhide, elkskin, buffalo Long (40cm+, full gauntlet) Heavy fleece, Kevlar reinforcement Heat-resistant general Foundry, forge, kiln, hot handling Sustained contact heat Aluminised Kevlar, heavy split cowhide Extra long (45cm+) Heavy fleece, often radiant-reflective coat The TIG-glove-for-everything rule: a common pattern in Reddit r/Welding is welders using a TIG glove for everything up to about 200 amps, then switching to a MIG/stick glove above that. The logic: low-amp work generates manageable heat and dexterity dominates; high-amp work flips the balance toward heat protection. Reasonable rule for solo hobbyists. Production fab shops typically run a dedicated set per process. Once you've chosen a category, narrow further on leather grade (next), cuff length, and lining. The 15 welding gloves at AIMS in /collections/welding-gloves cover all four categories — Bossweld dominates the range with TIG, MIG and stick options across goatskin, pigskin and split cowhide. AS/NZS 2161.4 — the Australian welding glove standard AS/NZS 2161.4:1999 (R2016) — Occupational protective gloves, Part 4: Protection against thermal risks (heat and/or fire) — is the Australian and New Zealand standard for thermal-rated protective gloves. It's the direct equivalent of EN 407, and most AU-supplied welding gloves cite both. Welding gloves sold for industrial use in Australia should carry the AS/NZS 2161.4 marking; gloves without it are not certified to perform in heat-and-fire conditions. The standard tests gloves against six performance properties. Each is rated 0–4 (or 0–3 for one), with higher numbers indicating better performance. Property Levels What it measures Flame spread 0–4 Time the glove keeps burning after contact with flame is removed (after-flame and after-glow time). Contact heat 0–4 Threshold temperature at which the glove transmits enough heat to cause pain (15s contact). Levels 1–4 = 100°C / 250°C / 350°C / 500°C. Convective heat 0–4 Time before flame-side temperature rises 24°C through the glove. Higher = longer time. Radiant heat 0–4 Time before radiant heat penetration causes 24°C rise. Critical for arc and overhead work. Small splashes molten metal 0–4 Number of metal droplets required to cause 40°C rise on inside surface. Large splashes molten metal 0–3 Mass of molten metal required to cause skin damage simulant. Foundry-relevant. You'll see a code like 413X4X on the glove — that's flame spread 4, contact heat 1, convective heat 3, radiant heat X (not tested), small splashes 4, large splashes X (not tested). An X means that property wasn't tested for that glove (typical for gloves not aimed at foundry work). For most welding work, look for level 3 or 4 on flame spread and at least level 2 on small splashes. Two sister standards apply: AS/NZS 2161.1 (general requirements — sizing, dexterity grading, manufacturer marking) and AS/NZS 2161.3 (mechanical risks — abrasion, cut, tear, puncture; equivalent to EN 388). A welding glove should ideally carry all three markings. Safe Work Australia's Welding processes guidance explicitly references the AS/NZS 2161 set for hand protection compliance. EN 12477 Type A vs Type B — the welder-specific standard EN 12477 is the European protective glove standard specifically for welders, and AU-imported welding gloves often carry it alongside AS/NZS 2161.4. It splits welding gloves into two types based on the protection-vs-dexterity trade-off: Type Use case Minimum AS/NZS 2161.4 levels Minimum AS/NZS 2161.3 (mechanical) levels Dexterity Type A — Heavy welding Stick (MMA/SMAW), heavy MIG, plasma cutting, oxy/acetylene cutting, foundry Flame spread 3, contact heat 1, convective heat 2, small splashes 3 Abrasion 2, cut 1, tear 2, puncture 2 Dexterity level 1 minimum (lower acceptable) Type B — High-dexterity TIG TIG (GTAW), MIG fine work, brazing, light spot welding Flame spread 2, contact heat 1, convective heat X, small splashes 2 Abrasion 1, cut 1, tear 1, puncture 1 Dexterity level 4 (highest) The trade-off explicit: Type A maximises heat and impact protection at the cost of dexterity; Type B maximises dexterity at the cost of heat performance. There's no Type A/B hybrid — by design, the standard forces a choice. Match Type A to stick/heavy MIG/plasma; match Type B to TIG/fine MIG. If your glove carries both AS/NZS 2161.4 and EN 12477 Type A, it's certified for stick and heavy work. EN 12477 Type B equates to a TIG-rated AU glove. Gloves sold without either standard reference are not appropriate for industrial welding regardless of how good the leather looks. Leather grades decoded — six options compared Glove leather is not interchangeable. Six grades dominate the welding glove market, each with distinct performance characteristics. The grade matters as much as the rating because the leather determines durability, dexterity, breathability and price for the same nominal thickness. Leather Heat resistance Dexterity Durability Best for Price tier Cowhide (top-grain) High Medium High MIG, light stick, general workshop Mid Cowhide (split) High Low–Medium Medium Stick, heavy MIG, budget workshop default Low–Mid Goatskin Medium–High High High (lanolin-conditioned, abrasion resistant) TIG, MIG fine work — the dexterity king Mid–High Pigskin Medium High High (water-resistant, doesn't harden after wet/dry cycles) TIG/MIG hybrid in damp environments Mid Deerskin Medium Highest (softest, molds to hand) Medium Premium TIG, fine pipe work High Elkskin Highest leather option Medium–High High (fire-resistant, premium feel) Premium stick, foundry, blacksmith High (specialty import) Buffalo Highest Low Highest (heaviest duty) Forge, blacksmith, barbed wire — overkill for normal welding High Goatskin is the TIG dexterity king. Natural lanolin keeps the leather supple even after heat cycling, and the tight grain resists abrasion despite being thinner than cowhide. It's why most premium TIG gloves are goatskin — the Bossweld TIG long and the Bossweld Goat Skin TIG 36cm with reinforced fingers and cowhide cuff use goatskin on the palm with cowhide on the protective cuff section. Cowhide split is the budget MIG/stick standard. "Split" refers to the lower (suede side) layer of cowhide after the top grain is separated; it's cheaper than top-grain and remains heat-resistant, just less abrasion-resistant. Most production workshops default to cowhide split for stick and heavy MIG. The Goat Split 40cm unlined and Goat Split 40cm fleece-lined at AIMS use this construction with full 40cm gauntlet cuffs. Pigskin's water resistance distinguishes it. Cowhide hardens after a wet/dry cycle (rain, sweat, washing). Pigskin doesn't — it stays soft. Critical for outdoor or marine welding where the glove gets wet. Less common in AU welding glove ranges than cowhide and goatskin. Deerskin softest, but durability shorter. Premium TIG choice for fine pipe work where every degree of finger movement matters. Doesn't last as long as goatskin under repeated spark contact. Elkskin and buffalo are specialty. Elkskin is the fire-resistance king at premium price — North American foundry standard, not common in AU industrial supply. Buffalo is for forge/blacksmith work or where extreme abrasion (barbed wire fencing, demolition) is the dominant risk; overkill for welding. Lining materials — the heat-protection trade-off The lining is what keeps the inside of the glove cool when the outside is hot. Three lining types dominate, with a fourth specialty option. Unlined — maximum dexterity, minimum heat protection. Standard for TIG. The Bossweld Goat Split unlined 40cm uses this approach. Cotton lined — light insulation, comfortable, affordable. Standard for MIG and light stick. Sweat absorbent — but matted cotton stops insulating once it's saturated. Fleece lined — heaviest insulation in mainstream products. Standard for stick, heavy MIG, and cold-environment work. The Bossweld Goat Split fleece-lined 40cm is the AIMS workhorse for stick. Kevlar/aramid stitched and lined — flame-resistant stitching prevents seam failure under heat (cotton stitching is the #1 short-life failure point on cheap gloves). The BossSafe Yellow Aramid Stitched and the entire Frontier Ultimate Welder Aramid Gauntlet range use aramid stitching for extended life. Worth the upgrade for daily-use professional welders. Aluminised heat shields and glove savers are a specialty fourth category. The BT/Bossweld Aluminised Kevlar Glove Saver (left hand) is a radiant-heat barrier worn over a normal welding glove for overhead welding, foundry pour observation, or any sustained radiant exposure. It reflects radiated heat rather than absorbing it. TIG welding gloves — geometry and dexterity priorities TIG gloves are the lightest in the welding range, prioritising tactile feedback so the welder can feel the filler rod's diameter and the puddle's behaviour through the leather. Goatskin is dominant; the glove typically runs unlined or thin-cotton-lined; cuffs are short to medium (28–36cm). The Bossweld TIG Long and Goat Skin TIG 36cm represent the AIMS TIG offering — both with reinforced fingers (the wear-out point) and cowhide cuff sections for forearm protection. Reinforced fingers matter. The fingertip and inside of the index/thumb wear out first because that's where the welder grips the filler rod and torch. A TIG glove without reinforcement at these points typically fails in weeks. Look for visible double-leather construction at the fingertips — every quality TIG glove has it. For TIG learning, see the TIG Welding Guide for process technique. The glove choice supports the technique — don't compromise dexterity for heat protection on TIG, you'll lose puddle control. MIG welding gloves — heat balance and spatter resistance MIG gloves sit between TIG and stick. They need enough heat protection to handle MIG spatter (particles up to 1500°C bouncing off the workpiece) and enough dexterity to handle the wire feed gun comfortably. Cowhide split or pigskin dominate; cotton or fleece lining; medium to long gauntlet cuffs (35–40cm) to protect against spatter rolling up the sleeve. The Bossweld Blue Welders Gauntlets, Blue Comfort 40cm, Green & Gold 16" and Black & Gold 16" are the AIMS MIG range. The 16-inch (40cm) cuff length is the standard for production MIG to keep spatter out of the sleeve cuff. The Frontier Gauntlet (one size fits all) is the budget option. For MIG technique and gun handling see the MIG Welding Guide. Match glove to amperage: under 200A you can run a TIG glove if dexterity matters; above 200A switch to a MIG gauntlet. Stick welding gloves — heaviest duty and the left-hand-only convention Stick welding (SMAW/MMA) generates more heat and bigger spatter than MIG, and the electrode is held in close proximity to the work for the entire bead. The glove for stick is the heaviest in the welding range: split cowhide (or elkskin in premium), heavy fleece lining, full 40cm+ gauntlet, often Kevlar/aramid stitching for seam integrity. The left-hand-only buying convention. Stick welders typically wear a heavy stick-spec glove on their electrode hand (left hand for right-handers) and a lighter MIG or general-purpose glove on their other hand. The reason: the electrode hand needs maximum heat protection while gripping the rod close to the arc; the other hand handles the electrode holder cable, holds the workpiece, or feeds new electrodes — tasks where dexterity matters more than heat. Two AIMS products explicitly serve this market as left-hand-only sales: the BossSafe Left-Hand Red Heavy Duty Welding Gloves (pair — both gloves left-handed) for the electrode hand, and the Frontier Leftie Welder Aramid Gauntlet Green (pack of 12, all left-hand) for the same role in volume. This is not about welder handedness — it's about buying convention. A right-handed welder buying a "leftie" pair is buying two left-hand gloves to cover the electrode hand for two days before replacing. The captures the 90 mo AU search volume for "lefties welding gloves" + "left hand welding gloves" + similar. For stick welding technique and electrode selection see the Stick Welding Guide. The Bossweld Goat Split fleece-lined 40cm is the AIMS stick workhorse if you're not buying left-hand-only. Cuff length — why 16-inch / 40cm is standard for serious work The cuff is the glove's forearm extension. Two reasons it matters: spatter management (sparks rolling up the sleeve land on bare skin if the cuff is too short) and forearm protection (radiant heat from the arc burns exposed skin within seconds). Cuff length should overlap with the welding jacket sleeve by at least 5cm to prevent the gap-burns that are common with short-cuff gloves. Cuff length Best for Trade-off Short (under 28cm) Bench TIG, hobbyist work, pipe work where reach matters Spatter and radiant heat hit forearm — must pair with long-sleeve jacket Medium (28–36cm) Production TIG, light MIG Compromise — adequate for most TIG, marginal for MIG Long (16-inch / 40cm) Production MIG, stick, plasma, foundry Reduces wrist articulation slightly — fine for amp-up work Extra long (45cm+) Foundry pour, overhead welding, blacksmith Restricts wrist movement — only for sustained high-radiation work Heat-resistant general gloves — foundry, forge and hot handling Heat-resistant gloves overlap with welding gloves in materials but not in design priority. Foundry, forge, kiln-tending and hot-metal handling need sustained contact heat protection — gloves rated to AS/NZS 2161.4 contact heat level 3 or 4 (350°C–500°C threshold). Welding gloves are designed for spark/spatter and short contact; heat-resistant gloves are designed for sustained grip on hot stock. The BT/Bossweld Aluminised Kevlar Glove Saver is the AIMS option for radiant-heat work. For sustained hot-metal handling, look for "kiln" or "foundry" rated gloves at level 3+ contact heat — these are typically thicker and heavier than welding gloves and have shorter dexterity ratings. What heat-resistant gloves are NOT for: grilling, oven mitts, BBQ. We get this question regularly — yes, welding gloves are heat-resistant, but they're sized and fitted for arc-welding ergonomics, not kitchen reach. A purpose-built BBQ/oven mitt is cheaper and fits the application better. The 600/mo "heat resistant gloves" search cluster has consumer audience contamination — this guide explicitly scopes to industrial use. Aluminised heat shields and glove savers Aluminised gloves and glove savers are the specialty radiant-heat solution for overhead welding, foundry observation and any work involving sustained exposure to radiated heat. The aluminium coating reflects infrared radiation rather than absorbing it — a radically different protection mechanism from leather, which absorbs and slowly transmits heat through the fabric. The BT/Bossweld Aluminised Kevlar Glove Saver (left hand) is sold as a glove saver — meaning you wear it over a standard leather welding glove for the radiant-heat exposure portion of the job, then remove it for normal work. The Kevlar substrate gives flame resistance; the aluminised face reflects radiant energy. Worn alone it doesn't have the contact-heat performance of a dedicated leather glove. This product is left-hand only because radiant overhead work and foundry-pour observation typically expose one hand more than the other. Pair with a normal right-hand welding glove from the same range for matched protection. Sizing welding gloves correctly Australian welding gloves use the AS/NZS 2161.1 size scale: numeric sizes 6–13 corresponding to hand circumference at the knuckles in centimetres. Size 9 (medium) fits a 23–24cm hand circumference; size 11 (large) fits 27–28cm. Most AU brands sell S/M/L/XL labelling that maps to sizes 8/9/10/11 respectively. Size Common label Hand circumference (cm) Hand length (cm — base of palm to middle finger) 7 XS 17–18 16–17 8 S 20–21 17–18 9 M 23–24 18–19 10 L 25–26 19–20 11 XL 27–28 20–21 12 XXL 29–30 21–22 Sizing matters more than fabric grade. A correctly sized welding glove maintains grip without restriction. Common sizing mistakes: Too loose: glove rotates on the hand mid-grip, fingertips don't reach the leather end, dexterity collapses, glove feels "floppy" on the wire feed gun. Fix: drop a size. Too tight: restricted blood flow during a long bead, finger fatigue within 30 minutes, sweat doesn't dissipate, leather hardens faster from absorbed sweat. Fix: go up a size or try a different brand's sizing system. One-size-fits-all gauntlets (like the Frontier Gauntlet One Size Fits All) work for medium-to-large hands but not for small hands or extra-large hands. Budget option, not a precision fit. Try gloves on with the welding jacket sleeve in place — the cuff overlap is part of the fit. AIMS welding glove range — Bossweld, Frontier, BossSafe and BT/Bossweld AIMS stocks 15 welding gloves across four brands at /collections/welding-gloves. Bossweld dominates (8 products) covering TIG through stick. Frontier (4) and BossSafe (2) add aramid-stitched and left-hand-only options. BT/Bossweld (1) adds the aluminised glove saver. We do not stock Elliotts (the dominant Australian welding glove brand by search volume) or imported brands like Tillman; if you're brand-loyal to Elliotts Big Red, our Bossweld and BossSafe equivalents cover the same AS/NZS 2161.4 performance levels at comparable price points.

We can usually source through our supplier network. Care, maintenance and when to discard Welding gloves are consumables, not capital equipment. Average life for daily-use leather welding gloves is 1–3 months for stick/heavy MIG and 3–6 months for TIG. Aramid-stitched gloves typically last 30–50% longer than cotton-stitched at the seams. Care during use: Don't wash leather gloves with water — the wet/dry cycle hardens cowhide. Brush off slag and dirt with a stiff brush. Don't store in direct sunlight — UV degrades leather faster than welding spark exposure. Don't dry on a heat source after sweating — surface heat hardens leather. Air-dry only. Rotate two pairs if you weld daily — letting one pair air out 24 hours doubles service life. Discard signs: Seam openings anywhere on the glove (cotton stitching has burned out) Hardened, cracked or curling leather — protection rating is gone even if the glove looks intact Visible burn-through, holes or patches of melted lining Lining bunched, matted or shifted out of position Cuff frayed or torn — spatter will breach the cuff Don't try to extend a damaged welding glove "until the next replacement order." A burn injury costs more than the glove. Common mistakes — eight forum-validated errors Mistake Why it fails Fix Cotton or "fake leather" gloves for welding Cotton ignites; vinyl melts onto skin. Both fail catastrophically under spark contact. 100% genuine leather, AS/NZS 2161.4 marked. Rubber or short-cuff gloves for welding Rubber transmits heat instantly; short cuffs leave forearm exposed to spatter and radiant heat. Minimum 28cm cuff for TIG, 35cm+ for MIG/stick. Using TIG gloves for stick welding TIG glove leather is too thin for stick spatter; seams burn through quickly; fingers get burnt through the leather. Stick = split cowhide or elkskin, fleece-lined, 40cm cuff minimum. Buying oversized "for comfort" Glove rotates on hand, fingertips can't reach leather end, dexterity collapses on TIG, slips off MIG gun. Drop a size. Welding gloves should fit snugly, not loosely. Buying undersized for tighter feel Restricted blood flow, finger fatigue within 30 minutes, sweat saturation faster. Up a size. Match hand circumference to AS/NZS 2161.1 size chart. Ignoring AS/NZS 2161.4 markings Glove may not be rated for welding heat — counter-display look-alikes from non-industrial brands fail under arc. Check for AS/NZS 2161.4 marking before buying. Six performance levels printed on cuff or label. Single glove pair across all welding processes One glove can't optimise for TIG dexterity AND stick heat protection. Run dedicated TIG and MIG/stick pairs. Match glove to process. Buying on price alone, not seam construction Cotton-stitched gloves fail at the seams within weeks under heavy MIG/stick. The glove looks intact but no longer protects. Aramid-stitched gloves extend service life 30–50%. Cost premium pays back within 2–3 replacement cycles. Frequently Asked Questions What's the Australian standard for welding gloves? AS/NZS 2161.4:1999 (R2016) — Occupational protective gloves, Part 4: Protection against thermal risks (heat and/or fire) — is the Australian and New Zealand standard. It's directly equivalent to EN 407, and most welding gloves carry both markings. Welding gloves should also carry AS/NZS 2161.1 (general requirements) and ideally AS/NZS 2161.3 (mechanical risks). The AS/NZS 2161.4 marking shows six performance levels: flame spread, contact heat, convective heat, radiant heat, small splashes molten metal, and large splashes molten metal — each rated 0–4. Can I use TIG welding gloves for MIG welding? For MIG work below about 200 amps, yes — many welders prefer the TIG glove's dexterity for fine wire feed control. Above 200A, the increased spatter and heat exposure overwhelms the thinner TIG leather and a MIG-specific gauntlet is needed. The Reddit r/Welding consensus is "TIG gloves up to 200A, swap to MIG above". For dedicated production MIG work or heavy MIG (>250A), use a purpose-built MIG glove with cowhide split leather and fleece lining. Are MIG or TIG gloves thicker? MIG gloves are noticeably thicker. TIG gloves prioritise dexterity and use thin goatskin or deerskin (typically 0.7–1.0mm leather), often unlined or with thin cotton lining. MIG gloves use thicker cowhide split or top-grain (typically 1.2–1.5mm+ leather) with cotton or fleece lining. The thickness difference is functional: TIG needs filler-rod feel; MIG needs spatter resistance. What type of gloves are recommended for stick welding? Stick (SMAW/MMA) needs the heaviest welding gloves: split cowhide or elkskin, heavy fleece lining, full 40cm+ gauntlet, ideally aramid-stitched seams. Stick generates more heat and bigger spatter than MIG, and the electrode hand is held in close proximity to the arc for the entire bead. Many stick welders buy left-hand-only "leftie" gloves (like the BossSafe Left-Hand Red Heavy Duty pair) for the electrode hand and pair with a lighter MIG glove on the other hand for cable handling and electrode changing. EN 12477 Type A is the relevant European rating for stick. Is goatskin or cowhide better for welding gloves? Different applications. Goatskin wins for TIG and fine MIG work — its natural lanolin keeps the leather supple, the tight grain resists abrasion despite being thinner, and the thinness preserves dexterity. Cowhide (especially split cowhide) wins for stick and heavy MIG — it's thicker, heat-resistant, abrasion-resistant, and cheaper for the same volume. Both are AS/NZS 2161.4 compliant when properly constructed; choose based on process. Workshops with multiple welding processes typically run both. What is the best leather for welding gloves? There's no single best — the answer depends on the process. Goatskin for TIG dexterity. Cowhide split for stick/heavy MIG durability. Pigskin if water resistance matters (outdoor/marine welding). Deerskin for premium TIG fine-pipe work. Elkskin for premium foundry/blacksmith heat. Buffalo for forge or barbed-wire-adjacent work. The leather grade matters as much as the AS/NZS 2161.4 rating because it determines durability, dexterity and price for the same nominal performance level. Should you wear gloves when TIG welding? Always. TIG generates the same UV and IR radiation as MIG and stick — even a few seconds of bare-skin exposure to a TIG arc produces a sunburn-equivalent injury. The arc temperature is 1,100–6,000°C; bare skin at any distance suffers radiated heat injury within seconds. The temptation to remove gloves for "better feel" on fine work is the #1 hand-injury cause among hobbyist TIG welders. Use a thin goatskin TIG glove if dexterity is the issue — never bare hands. Why are some welding gloves left-hand only? Stick welders typically wear a heavy stick-spec glove on their electrode hand and a lighter MIG/general-purpose glove on the other hand. The electrode hand needs maximum heat protection while gripping the rod close to the arc; the other hand handles cable, holds the workpiece, or feeds new electrodes — tasks where dexterity matters more. A "leftie" pair is two left-hand gloves to cover the electrode hand for two days before replacing. This is buying convention, not handedness — a right-handed welder typically has their electrode in the dominant hand and would buy right-hand-only pairs (less common in AU supply). The BossSafe Left-Hand Red Heavy Duty pair is the AIMS option for left-handed electrode work. What is AS/NZS 2161.4? AS/NZS 2161.4:1999 (R2016) is the Australian and New Zealand standard for occupational protective gloves protecting against thermal risks — heat and fire. It tests gloves on six performance properties (flame spread, contact heat, convective heat, radiant heat, small splashes molten metal, large splashes molten metal), each rated 0–4. The standard is the direct equivalent of EN 407. AU-imported welding gloves typically carry both markings. Safe Work Australia's Welding processes guidance references AS/NZS 2161.4 as the relevant hand-protection standard for welding work. What's the difference between EN 12477 Type A and Type B? EN 12477 splits welding gloves into two types based on protection-vs-dexterity trade-off. Type A is heavy welding (stick, heavy MIG, plasma, oxy/acetylene cutting, foundry) — minimum AS/NZS 2161.4 levels of flame spread 3, contact heat 1, convective heat 2, small splashes 3, with mechanical performance to AS/NZS 2161.3. Type B is high-dexterity welding (TIG, fine MIG, brazing) — lower minimum heat performance (flame spread 2, contact heat 1, small splashes 2) but minimum dexterity level 4 (the highest rating). The standard forces a choice — there's no Type A/B hybrid. Match Type A to stick/heavy MIG; match Type B to TIG. Can I use welding gloves for grilling or oven work? Welding gloves are heat-resistant, but they're sized and fitted for arc-welding ergonomics — not kitchen reach or BBQ-tongs use. The 40cm gauntlet that protects against MIG spatter just gets in the way around an oven door. A purpose-built oven mitt or BBQ glove (which doesn't need AS/NZS 2161.4 certification) is cheaper and fits the application better. The "heat resistant gloves" search cluster has consumer-audience contamination — this guide explicitly scopes to industrial welding and hot-metal handling. How long should welding glove cuffs be? For TIG, 28–36cm is typical. For MIG, stick, plasma and foundry, 16-inch (40cm) is the production standard. Extra-long 45cm+ cuffs are reserved for foundry pour observation, overhead welding and blacksmith work where sustained radiant exposure dominates. The cuff should overlap with the welding jacket sleeve by at least 5cm to prevent gap-burns at the wrist — the most common short-cuff injury site. Don't compromise on cuff length to save a few dollars; the bare forearm is the easiest place to get burnt during welding. How do I size welding gloves correctly? Measure hand circumference at the knuckles (excluding thumb). Size 9 (medium / "M") fits 23–24cm; size 11 (large / "XL") fits 27–28cm. AS/NZS 2161.1 specifies the size scale 6–13. Most AU welding gloves use S/M/L/XL labelling that maps to sizes 8/9/10/11 respectively. Try gloves on with the welding jacket sleeve in place — the cuff overlap is part of the fit. Common mistakes: too-loose gloves rotate on the hand and collapse dexterity; too-tight restrict blood flow and accelerate fatigue. If between sizes, go up for MIG/stick, down for TIG. What's the best welding glove brand sold in Australia? The most-searched AU brand is Elliotts (with the "Big Red" line), followed by Pyromate. AIMS does not stock Elliotts — our equivalent industrial-grade ranges are Bossweld (8 products covering TIG/MIG/stick, including the workshop-workhorse Bossweld Goat Split fleece-lined 40cm), Frontier (4 products including the aramid-stitched Ultimate Welder range and the Leftie Welder for left-hand stick), BossSafe (Yellow Aramid Stitched plus the Left-Hand Red Heavy Duty for stick electrode work), and BT/Bossweld (Aluminised Kevlar Glove Saver for radiant work). All are AS/NZS 2161.4 compliant and cover comparable price/performance points to Elliotts. If you need Elliotts specifically, call the AIMS team — we can usually source through our supplier network. How long do welding gloves last? Daily-use leather welding gloves typically last 1–3 months for stick and heavy MIG, 3–6 months for TIG. Aramid-stitched gloves (Frontier Ultimate range, BossSafe Yellow Aramid) typically last 30–50% longer than cotton-stitched at the seams — the seams are usually the first failure point on cheaper gloves. Care matters: don't wash with water (cowhide hardens after wet/dry cycles), don't dry on heat sources, store away from direct sunlight, rotate two pairs to let leather air out. Discard signs include open seams, hardened/cracked leather, burn-through holes, and shifted lining. Don't try to extend a damaged welding glove — a hand-burn injury costs more than the glove. People Also Ask — Welding Gloves Q: What welding gloves are best for TIG welding? TIG welding requires fine dexterity for manipulating the torch and filler wire, so TIG welding gloves are typically made from thin, supple leather (often goatskin or deerskin) that offers better feel and sensitivity than the heavier gloves used for MIG or stick welding. The thinner material still provides heat protection from the lower heat input of TIG but allows the precise control the process demands. Q: Can I use MIG welding gloves for stick welding? MIG welding gloves can be used for stick (MMAW) welding at lower amperages, but are not ideal for heavy stick work. Stick welding generates higher spatter, more heat at the electrode holder, and more radiant heat from the arc than most MIG applications. Heavy-duty stick welding gloves are typically longer (providing wrist and forearm protection), made from thicker leather, and more heat-resistant than standard MIG gloves. For regular stick welding, purpose-specific gloves are safer. Q: What Australian standard applies to welding gloves? Welding gloves in Australia are assessed under AS/NZS 2161.4, which covers protective gloves for welding and allied processes. This standard specifies performance requirements for heat and flame resistance, mechanical protection, and construction. Gloves certified to AS/NZS 2161.4 will carry the standard's designation on the label along with their protection level ratings. Q: How do I know when to replace welding gloves? Welding gloves should be replaced when the leather becomes stiffened, cracked, or hardened from repeated heat exposure; when the stitching breaks down or seams open; when burn holes or thin spots develop in the palm or finger areas; or when the gloves no longer fit correctly due to distortion. Welding gloves that have been contaminated with oil or flammable substances should be taken out of service immediately, as contaminated leather can ignite. Q: Do welding gloves protect against electric shock? Dry leather welding gloves provide a modest level of electrical resistance, but are not designed or tested as electrical insulating gloves. They are not a substitute for purpose-designed electrically insulating gloves where live electrical work is involved. Welding creates an electrical circuit — the gloves reduce incidental contact risk with the electrode holder, but should not be relied upon for high-voltage electrical protection.

Read moreMagnetic Lifter Guide: Permanent, Electro-Permanent (Magswitch) & Electromagnet Selection
A magnetic lifter — also called a lifting magnet — is a below-the-hook lifting device that grips a steel load by magnetic attraction rather than by clamping or wrapping. Hook one onto a chain block, electric hoist, jib crane or overhead crane, switch the magnet on against the load, and the magnetic field generated inside the lifter holds the steel firmly through the lift. When the load is set down, switch the magnet off and the lifter releases. No drilling, no slinging, no clamping forces on the workpiece. For Australian fabrication shops, machine shops, steelyards, and maintenance workshops handling steel plate, sheet, billet, pipe and round bar, the magnetic lifter is the fastest tool in the lifting toolbox. A 1-tonne magnetic lifter cycles a load in seconds — pick up, lift, set down, release — versus the 30+ seconds of slinging and unslinging through holes that don't exist. The trade-off is geometric and material discipline: the lifter only works on ferrous steel, only on flat surfaces, and only above a minimum plate thickness. Get any of those wrong and the load drops. This guide is the comprehensive reference for magnetic lifters in Australian industry. We cover the three types (permanent, electromagnet, electro-permanent), how Magswitch's switchable rare-earth technology works, the pull-off vs Safe Working Load distinction that catches buyers out, surface and material limits, AS 4991 compliance, and the AIMS range across Magswitch MLAY 1000, MLAY 600 and Prolift lines. Browse the lifting magnet range or call (02) 9773 0122 for sizing help. Magnetic lifters sit alongside beam clamps, plate clamps, and the slings triple (chain, wire rope, synthetic) in the AU rigging toolbox. Each tool wins on a different combination of load shape, material, surface condition, and cycle frequency. What a magnetic lifter is — and what it isn't A magnetic lifter is a rated lifting device that uses a controlled magnetic field to attach to a ferrous steel load. The magnetic field is generated by either permanent rare-earth magnets, an electromagnet (energised coil), or an electro-permanent system that combines both. The load attaches when the magnetic field is engaged and releases when it's switched off. It's not the same product as a magnetic-base drill stand, a welding ground clamp magnet, a magnetic sweeper, a pickup tool, or a magnetic chuck. Those are positioning, holding, retrieval or fabrication tools. A lifting magnet is a certified rated lifting device that complies with AS 4991:2004 Lifting Devices and is supplied with an individual test certificate, a unique serial number, and a stamped Working Load Limit (WLL). The simple test: a lifting-rated magnetic lifter is stamped with WLL in tonnes or kilograms, the AS 4991:2004 standard reference, the manufacturer name, a unique serial number, and a minimum plate thickness for the rated WLL. Without those markings, the device is not rated lifting equipment regardless of what it can pick up. Critical: a magnetic lifter only works on ferrous steel. Aluminium, brass, copper, plastic, timber, austenitic stainless steel grades 304 and 316, and most non-ferrous metals are non-magnetic — a lifting magnet will not pick them up. Magnetic stainless grades exist (400-series ferritic and martensitic) but most architectural and industrial stainless used in Australia is austenitic 304 or 316. Confirm the material before the lift. The forum-validated apprentice trap on r/Welding: "I once gave one of our young guys a lifting magnet and asked him to grab a piece of stainless plate for me." The plate didn't move. The three types — permanent, electromagnet, electro-permanent Magnetic lifters fall into three technology categories. Each has a different operating principle, different power requirements, and different fail-safe behaviour. Type How it generates the field Switching mechanism Power required during lift Fail-safe behaviour Permanent Always-on rare-earth or ferrite magnets Mechanical lever moves an iron pole-piece to short-circuit (off) or align (on) the magnetic flux path None Stays attached — fail-safe Electromagnet Coil energised by electric current generates magnetic field Current on / current off Continuous AC or DC supply Drops the load on power loss — battery backup mandatory Electro-permanent (Magswitch) Two opposing rare-earth permanent magnets; one fixed, one rotating Mechanical lever rotates the second magnet to either cancel (off) or reinforce (on) the fixed magnet's field None during lift Stays attached — fail-safe (mechanical not electrical) For most Australian industrial applications — fabrication, machining, steelyard handling, maintenance — the choice is between a permanent magnetic lifter (cheapest entry) and an electro-permanent Magswitch (premium tier). True electromagnets are reserved for very high capacities (10T+) and scrap handling where rapid magnetisation/demagnetisation cycling justifies the cabling and battery backup. AIMS stocks the permanent and electro-permanent types. How Magswitch electro-permanent technology works A Magswitch lifting magnet uses two rare-earth permanent magnets stacked vertically inside a cylindrical housing. The lower magnet is fixed; the upper magnet is mounted on a rotating spindle controlled by an external lever. The trick is in the geometry of how the two magnets' fields combine. When the lever is in the OFF position, the rotating upper magnet is oriented so its north pole sits above the fixed magnet's north pole and its south pole above the fixed south. The two fields oppose each other — they form a closed loop within the lifter housing and almost no flux escapes through the base plate. The lifter is essentially "magnetically silent" — touch it to a steel plate and you feel almost nothing. When the lever is rotated 180° to the ON position, the upper magnet flips: its north pole is now above the fixed south pole, and its south above the fixed north. The two fields reinforce each other and the combined flux flows out through the base plate and into the load. The lifter develops its full rated grip — anywhere from 100kg to 4,000kg+ depending on the model. The result is a lifting magnet with the safety advantages of a permanent magnet (no power required, fail-safe under power loss) plus the operational convenience of an electromagnet (rapid switchable on/off). The mechanical lever is the only moving part. The forum consensus on r/AskEngineers and r/Machinists is consistent: Magswitch's switchable design is the engineering benchmark for safe controlled magnetic lifting. The Magswitch MLAY 1000 is the workhorse single-cell electro-permanent lifting magnet — 1,000 lb (454 kg) Safe Working Load on flat steel ≥25mm thick. The MLAY 1000 series scales by adding cells in line: MLAY 1000x2 doubles the capacity to 908kg, MLAY 1000x3 reaches 1,362kg, and MLAY 1000x4 reaches 1,816kg. The MLAY 600 series follows the same pattern at lower capacity but smaller footprint — useful when access geometry matters more than peak load. Pull-off force vs Safe Working Load — the most-misread spec Pull-off force is the maximum force required to detach a magnet from a perfectly-prepared load under laboratory test conditions. Safe Working Load (SWL) is the rated lifting capacity for routine industrial use. The two numbers are different. Pull-off is typically 2.5 to 3.5× the SWL, depending on the manufacturer's design factor. The marketing "1320 lb pulling capacity" or "880 lb pull" stamped on cheap import lifters is the pull-off figure, not the SWL. Magswitch's official MagDolly manual states the rule plainly: "All magnetic heavy lifting magnets are de-rated for safe lifting. De-rating reduces the magnet's allowed lifting capacity down to the Safe Working Load (SWL)." The de-rating accounts for surface conditions, dynamic loads during the lift, and the inherent variability of magnetic adhesion under field conditions versus a controlled test bench. Term What it measures Conditions Use for Breakaway / pull-off force Force required to detach the magnet at the test instant Lab — perfectly flat, polished, machined, ≥25mm low-carbon steel test plate Comparison between magnet designs only — never use as lifting capacity Safe Working Load (SWL) / Working Load Limit (WLL) Rated lifting capacity for routine industrial use Real-world derated for surface variation, dynamic load, safety factor 2.5:1 to 3.5:1 The number that goes on the load plan — never exceed Safety factor Ratio of breakaway to SWL Typical AU industrial: 3:1 (Magswitch, premium AU brands), 2.5:1 (budget), 3.5:1 (some specialist heavy-duty) Identifying genuine industrial-grade vs over-stated import claims The practical buying rule: ignore the breakaway figure printed on the front of the box, find the SWL on the data plate, confirm the safety factor, and confirm AS 4991 compliance. A "1000lb pulling capacity" cheap import with no AS 4991 stamp is not 1000lb of lifting capacity — typically it's 300-400lb SWL with a 2.5:1 factor, and even that assumes perfect surface conditions. Surface conditions — flat, clean, thick enough The three conditions that determine whether a magnetic lifter develops its rated capacity are: surface flatness, surface cleanliness, and plate thickness. Get any one wrong and the SWL drops dramatically — sometimes to a fraction of the marked rating. Flatness. The magnetic field flows from the lifter's base into the load through the contact area. A flat lifter base on a flat plate face gives 100% contact; a flat lifter base on a curved surface (round bar, pipe, dished plate) gives a tiny line-contact patch that may be only 10-20% of the rated contact area, and the SWL falls proportionally. The forum-validated rule from r/metalworking is direct: "Lifting magnets are only reliably safe when used with flat surfaces. Trusting a lifting magnet to perform safely on curved surfaces is never safe." Some specialist lifters have V-grooves cut into the base for round material — capacity is rated separately for round stock and is typically 30-50% of the flat-plate rating. Cleanliness. Rust scale, paint, mill scale, oil, grease, water, and dirt all interpose between the lifter base and the load. Each layer adds an air gap that the magnetic field must bridge — and magnetic flux drops sharply with air-gap distance. A 0.5mm rust scale or paint layer can reduce capacity by 30-50%. Magswitch's MagDolly manual is explicit: surface preparation requires removing scale, rust, and paint before the lift. The forum direct quote on r/metalworking: "the manual wants you to remove scale/rust/paint as well." Thickness. Each lifting magnet specifies a minimum plate thickness for the rated SWL. Below that thickness, the magnetic flux saturates the plate and excess field leaks out the back face — capacity drops linearly with thickness reduction. Typical minimums: Lifter capacity (SWL) Typical minimum flat-plate thickness for rated SWL Below this thickness 100 kg 10 mm Capacity drops linearly — 8mm typically gives ~80%, 5mm gives ~50% 300 kg 15 mm Manufacturer derating chart applies 500 kg (Prolift) 20 mm Below 20mm, consult manufacturer derating curve 600 kg (Magswitch MLAY 600) 15 mm Magswitch publishes specific derating for thinner stock 1000 kg (Magswitch MLAY 1000) 25 mm Below 25mm, capacity derates per Magswitch chart 2000 kg+ 40 mm+ Heavy plate only at full rating Manufacturer derating curves cover the thickness vs capacity relationship below the minimum. They're worth printing and keeping on the lifter cabinet. For thin sheet stock that falls well below the minimum, vacuum lifters or sheet handling slings are typically the better tools — see our Plate Clamp Guide for the alternative methods. What magnets DO and DON'T pick up — material guide Magnetic lifters work on ferrous (iron-bearing) steel only. The strength of attraction depends on the material's magnetic permeability — how readily the material conducts magnetic flux. Material Magnetic? Lifting capacity (vs rated SWL on low-carbon steel) Mild steel (AS/NZS 3678 grade 250/300/350) ✓ Strongly magnetic 100% — the rated baseline Cast iron (grey, ductile) ✓ Magnetic but porous ~50% — porous structure leaks flux High-carbon steel / spring steel ✓ Magnetic but harder ~80-90% — slightly reduced permeability Tool steel (hardened) ✓ Magnetic ~50-70% — high carbon and hardening reduce permeability 400-series stainless (ferritic, martensitic — e.g. 410, 430) ✓ Magnetic ~50-70% 304 / 316 stainless (austenitic) ✗ NON-magnetic 0% — magnet won't pick it up Aluminium (any grade) ✗ Non-magnetic 0% Brass, bronze, copper ✗ Non-magnetic 0% Lead, zinc, tin ✗ Non-magnetic 0% Titanium ✗ Effectively non-magnetic 0% Galvanised steel ✓ Magnetic (steel substrate) ~95% — galvanising adds tiny air gap; minimal effect Painted / coated steel ✓ Magnetic (steel substrate) Varies — paint thickness adds air gap; typical derate 10-30% The single most important material rule for AU industrial users: 304 and 316 austenitic stainless steel is non-magnetic. A magnetic lifter will not pick up a 304 or 316 plate. This is the most-cited apprentice trap in welding and fabrication forums. Most architectural stainless, food-grade stainless, and chemical-industry stainless plate is austenitic. For stainless plate handling, use non-marring plate clamps with leather pads or vacuum lifters. Plate thickness, surface area, and de-rating in practice The published SWL for a magnetic lifter is the value at full conditions: flat steel, clean surface, plate at or above the minimum specified thickness. For real-world plate that doesn't meet all three conditions, capacity is derated multiplicatively. A worked example shows the maths: Worked example. Lifting an 18mm thick mill-scale-coated mild steel plate measuring 1500 × 750 mm with a Magswitch MLAY 1000 (rated SWL 454 kg / 1000 lb on ≥25mm clean flat steel). Thickness derating. Plate is 18mm against 25mm minimum. Magswitch chart shows ~80% capacity at 18mm. Capacity = 454 × 0.80 = 363 kg. Surface derating. Mill scale on the surface adds typically 0.2-0.5mm of low-permeability layer. Conservative derate 25%. Capacity = 363 × 0.75 = 273 kg. Plate weight check. 18 × 1500 × 750 mm at 7,850 kg/m³ = 159 kg. Well within the 273 kg derated capacity. Margin check. Derated capacity (273 kg) ÷ load (159 kg) = 1.7× margin. Acceptable for a routine lift. For loads where the margin falls below 1.5× after derating, step up to the next lifter size — MLAY 1000x2 at 908 kg SWL, for example, gives much more comfortable margin on the same plate. Or strip the mill scale before the lift to recover the surface-condition derate. Hand-held vs hoist-attached lifters Magnetic lifters split into two product classes by how they're operated. Hand-held lifters are designed for one person to manually pick up a load using the lifter's integrated handle. Capacities run from 60 kg to roughly 200 kg — small enough to lift by arm strength alone. Used for sheet metal handling, small fabrication work, sheet stack picking, and workshop transfers within arm's reach. The Magswitch Fixed Single Hand Lifter (rated 390 lb breakaway / ~120 kg SWL) and Magswitch Fixed Dual Hand Lifter (rated 780 lb breakaway / ~240 kg SWL with two-person operation) are AU workshop standards. Hoist-attached lifters are designed to hang from a chain block, electric hoist, jib crane, or overhead bridge crane. Capacities run from 100 kg to 4,000 kg+ and the lifter has a robust shackle or bail attachment at the top. The Magswitch MLAY 600 and MLAY 1000 series and the Prolift 500 kg are the AIMS hoist-attached range. These are the workhorse lifters for heavy industrial steel handling. The choice is straightforward: weight of routine load. Below 100 kg, a hand-held lifter is faster — no rigging, no overhead structure required. Above 200 kg, a hoist-attached lifter is the only option. Between 100 and 200 kg, it depends on lift height, distance, and frequency. The Magswitch ecosystem — Hand Lifter, Mag Dolly, MagReach Magswitch's electro-permanent technology has spawned a family of related products beyond the core MLAY lifting magnets. Several are stocked at AIMS for specialty applications. Fixed Single Hand Lifter — manual hand-held lifter, 390 lb breakaway. Single-person sheet handling. Fixed Dual Hand Lifter — two-handle version, 780 lb breakaway. Two-person heavier sheet lifting or longer plate handling. MagReach 400 — extended-reach magnetic retrieval tool, 400 lb breakaway, 50.5–90 inch reach. Recovery of ferrous items dropped into pits, drains, machinery interiors, or overboard. A specialty product but useful in mining, marine, and heavy maintenance work. Mag Dolly 917mm — wheeled trolley with integrated lifting magnet, designed for moving long stock (rails, beams, pipes) along a fabrication shop floor. The magnet engages the steel; the dolly's wheels support the load weight; the operator pushes the assembly along. For the core lifting application — picking up a load, lifting it with a hoist, transporting and setting down — the MLAY 600 and MLAY 1000 series are the AIMS workhorse range. The ecosystem products fill niche applications that arise in real workshops. Multi-magnet rigging for long stock For long beams, rails, or pipes, a single lifting magnet at one point applies a bending moment to the load and concentrates the lifting force at a small contact area. Two or more magnetic lifters connected via a spreader bar or lifting beam distribute the load across multiple pickup points and eliminate the bending stress. The standard configuration: two lifting magnets, each rated for at least 60% of the load weight, attached at the 1/4 and 3/4 points along the load length, hanging from a rated lifting beam (spreader bar) above. The spreader bar attaches to the chain block or hoist via a single vertical line. Each magnet sees vertical load only — no bending, no side load, no pry force. Critical: do not rig multiple slings to a single magnetic lifter at angles to vertical. The forum-validated rule from r/Rigging applies to magnets the same as to beam clamps: any side load on the lifter base creates pry forces that can defeat the magnetic adhesion. The lifter base wants to peel off the load. Multi-leg slings need a spreader bar or lifting beam between the slings and the magnet. For long-stock handling at high cycle rate, the Magswitch Mag Dolly or specialist multi-cell heavy lifter assemblies are purpose-designed alternatives. Contact us for engineered multi-magnet configurations. AS 4991:2004 — the Australian standard Magnetic lifters used in Australian industrial lifting comply with AS 4991:2004 Lifting Devices — the same standard governing beam clamps, plate clamps, and other below-the-hook lifting devices. Compliant magnetic lifters carry an AS 4991 stamp on the body or data plate, plus: Manufacturer name and country of origin Working Load Limit (SWL) in tonnes or kilograms Minimum plate thickness for the rated SWL Maximum operating temperature Unique serial number traceable to the individual test certificate Date of manufacture The standard requires a design factor of at least 3:1 for permanent and electro-permanent magnetic lifters — meaning the breakaway force must be at least 3× the SWL. For premium AU and global manufacturers (Magswitch, Eclipse, Walmag, Goudsmit), the design factor is typically 3:1 to 3.5:1. For cheap imports (Vevor, no-name) the factor may be quoted as 2.5:1 — at the lower end of the range and without independent AS 4991 verification. European EN 13155 is the equivalent international standard. AU principal-contractor sites typically require AS 4991 specifically, not just EN 13155. Magswitch certifies its industrial lifting range to AS 4991:2004 plus ISO 9001 quality management. Pre-use inspection Pre-use inspection takes 60 seconds and catches the failures before they happen. Six-point check: Check What you're looking for Data plate / WLL marking Legible SWL, AS 4991, manufacturer, serial number, minimum plate thickness. If you can't read it, the lifter is out of service. Switching lever action Lever moves smoothly through full travel between OFF and ON positions. Detents engage cleanly. No notching, sticking, or excessive force required. Lock pin / safety latch Lock pin engages in ON position to prevent accidental release under vibration. Pin springs back out cleanly when released. Base plate condition Base flat, free of nicks, gouges, chips, or rust pitting. Surface clean and dry. The base is the magnetic contact area — damage = lost capacity. Lifting eye / shackle Eye not opened up, no visible elongation, no cracks in the welds. Shackle pin secure if shackle is permanently fitted. Test certificate currency Periodic inspection within 6-12 months. Annual NATA proof-test for hire-fleet equipment on regulated sites. The functional pre-use test: with the magnet OFF, place the base on a clean steel test plate. Switch ON. Confirm the magnet attaches firmly (a small pull should not detach it). Switch OFF. Confirm the magnet releases freely. Damaged or sticky-lever lifters go out of service until inspected by a competent person.

Battery backup mandatory. Permanent or electro-permanent (Magswitch) types are inherently fail-safe — no power required during lift. Magnet won't pick up the load (304/316 stainless) Material is austenitic stainless — non-magnetic. Apprentice trap. Confirm material before lift. For 304/316 use plate clamps or vacuum lifters. Plate slips or peels off mid-lift Surface contamination (rust scale, paint, oil), insufficient plate thickness, or curved surface. Surface preparation per manufacturer manual. Confirm plate thickness ≥ minimum spec. Flat surfaces only unless V-grooved lifter on round stock. Lever rotates partially / weak grip Lever not fully engaged to ON position; lock pin not secured. Always rotate lever to detent stop. Verify lock pin engaged before lifting load. Heat-induced capacity drop Load (e.g. just-welded plate, hot-rolled stock, parts straight from heat treat) above magnet's max operating temperature. Most rare-earth permanent magnets lose capacity above 80°C; some grades fail above 120°C. Wait for parts to cool before lifting. Pry-off from side-load with multi-leg sling Operator rigged 4-leg sling directly from the magnet's lifting eye instead of through a spreader bar. Multi-leg slings always through a lifting beam or spreader bar. Single vertical line direct from hoist. Overload on round bar or pipe Flat-base magnet used at full SWL on round stock with line-contact only. Round-stock derating typically 30-50% of flat-plate SWL. Use V-grooved magnet or specialist pipe lifter. Operator misuse / inadequate training Most documented incidents — see r/Rigging field reports. Operator licensing (CPCCLDG3001 dogging minimum), manufacturer-supplied training, supervised first lifts on each new lifter type. Lifting magnets vs plate clamps vs vacuum lifters Magnetic lifters are not the only option for handling steel plate. The right tool depends on material, surface condition, cycle rate, and load shape. Method Best for Limitations Magnetic lifter High-cycle ferrous steel handling, flat plate, sheet, billet Ferrous steel only; flat and clean surfaces; minimum plate thickness Plate clamps Any plate material (incl. stainless, aluminium); curved or coated surfaces; outdoor work Slower to fit and remove; teeth-marked plate face (toothed clamps); horizontal type requires pairs Vacuum lifters Smooth thin sheet (steel, glass, plastic, painted); marking-sensitive surfaces Surface must be smooth and clean; vacuum loss = load drops; perforated stock won't seal Slings around the load Any load shape with profiled edges or designed lift holes; non-magnetic materials; outdoor field work Slowest; needs lift holes or basket geometry; sling damage from sharp edges Most production-rate fabrication shops have all three — magnetic lifters for the bulk of routine ferrous work, plate clamps for stainless and outdoor jobs, and slings for special cases. The forum consensus from r/Rigging confirms this: magnets and plate clamps are not competitors; they're complementary tools for different jobs.

Selection checklist + how to order A practical pre-order checklist: Confirm material is ferrous steel. Mild steel, structural steel, carbon steel, ferritic stainless = yes. Austenitic 304/316 stainless, aluminium, brass, copper = no. Measure plate thickness. Must be ≥ the lifter's minimum spec for full SWL. Below minimum, apply manufacturer derating chart. Assess surface condition. Mill scale, rust, paint, oil all derate capacity. Plan to clean to bright steel for full SWL, or apply 25-50% surface derating. Confirm load weight with margin. Derated SWL must exceed load weight by at least 1.5× for routine work, 2× for critical lifts. Select capacity. Magswitch MLAY 600 single cell for ~270 kg, MLAY 1000 single cell for ~450 kg, larger multi-cell models or two-magnet rigs for heavier loads. Hand-held or hoist-attached? Hand-held for <100 kg routine; hoist-attached for >200 kg or repetitive work. Confirm AS 4991:2004 compliance on the data plate. Non-negotiable. Operator licensing — dogging or rigging licence as required (CPCCLDG3001 for hoist-attached lifting work). The five most common buyer mistakes — every one of them avoidable: Reading the breakaway/pull-off figure as the lifting capacity (it's typically 3× the actual SWL). Buying for a stainless steel application without confirming the material is magnetic (304/316 = no). Undersizing the lifter for the plate thickness available (thin plate dramatically derates). Choosing a flat-base magnet for round bar or pipe handling without checking the round-stock derate. Buying a cheap import without AS 4991 compliance to save money on a safety-critical lift. Frequently Asked Questions What is a lifting magnet used for? A lifting magnet (also called a magnetic lifter) is a below-the-hook lifting device used to attach a steel load to a chain block, electric hoist, jib crane or overhead bridge crane via magnetic attraction. Common applications include moving steel plate between racks, picking single sheets from a stack, transferring billet between workstations, handling structural sections on a fabrication line, and retrieving ferrous items from drains, pits, or machinery interiors. What's the difference between a permanent magnet, electromagnet, and Magswitch lifter? A permanent magnetic lifter uses always-on rare-earth or ferrite magnets switched between pole-piece configurations by a mechanical lever. An electromagnet uses an electric coil that requires continuous power during the lift; power loss = dropped load. A Magswitch electro-permanent lifter uses two opposing rare-earth permanent magnets switched between cancelling and reinforcing positions by a mechanical lever — no power required, fail-safe, and rapidly switchable. Magswitch is the modern AU industrial standard combining the best features of both. How does a Magswitch magnetic lifter work? A Magswitch lifter contains two rare-earth permanent magnets stacked vertically. The lower magnet is fixed; the upper magnet rotates on a spindle controlled by an external lever. In the OFF position the two magnets oppose each other, forming a closed loop within the housing — almost no flux escapes. In the ON position the upper magnet flips 180°, so the two fields reinforce each other and full flux flows out through the base plate into the load. The mechanical lever is the only moving part; no electric power is required during the lift. Will a lifting magnet pick up stainless steel? Only ferritic and martensitic 400-series stainless grades (e.g. 410, 420, 430). Austenitic 304 and 316 stainless — the most common architectural, food-grade and chemical-industry stainless used in Australia — is non-magnetic; a lifting magnet will not pick it up regardless of plate thickness or magnet capacity. Confirm the grade with a small test magnet before planning a magnetic lift on stainless plate. For 304/316 plate handling, use a non-marring plate clamp or vacuum lifter — see our Plate Clamp Guide. What's the difference between pull-off force and Safe Working Load (SWL)? Pull-off (or breakaway) force is the maximum force required to detach a magnet from a perfectly-prepared load under laboratory conditions — flat, clean, machined, low-carbon steel test plate at full thickness. Safe Working Load (SWL) is the rated lifting capacity for routine industrial use, derated from the pull-off figure by a safety factor (typically 3:1) to account for surface variation, dynamic loads, and field conditions. The marketing "1000 lb pull" on cheap import lifters is the breakaway figure; the SWL is typically 300-400 lb. Always read the SWL from the data plate, not the marketing claim. What plate thickness do I need for a 1000 kg lifting magnet? Approximately 25mm of flat low-carbon mild steel is the typical minimum thickness for full 1000 kg SWL on a single-cell heavy lifter (e.g. Magswitch MLAY 1000). Below 25mm, magnetic flux saturates the plate and excess field leaks through to the back face — capacity drops linearly. Manufacturers publish derating curves: at 18mm typical capacity is ~80%, at 12mm ~60%, at 6mm ~40%. For thinner plate, step up to a multi-cell magnet (MLAY 1000x2 spreads the flux across more contact area) or use plate clamps instead. Can I use a lifting magnet on a curved surface or pipe? Generally no with a flat-base magnet. The magnetic field flows from the lifter base into the load through the contact area; a flat base on a curved surface gives only a tiny line-contact patch and capacity falls to 30-50% of the rated flat-plate SWL. Specialist V-grooved lifters are designed specifically for round bar and pipe — the V-groove maximises contact area against the curved surface. Round-stock SWL is rated separately on the data plate and is significantly lower than the flat-plate rating. For pipe handling, see specialist pipe lifters or use slings. Why do I need to clean the surface before lifting? Magnetic flux drops sharply across air gaps. Rust scale, paint, mill scale, oil, grease, water, and dirt all act as low-permeability layers between the lifter base and the load — each layer reduces effective flux transfer. A 0.5mm rust scale or paint layer can reduce capacity by 30-50%. Magswitch's MagDolly manual is explicit on this: surface preparation requires removing scale, rust, and paint to bright steel before the lift for the rated SWL. Without preparation, the lifter is operating in the manufacturer's derating zone. Do lifting magnets comply with AS 4991? All lifting magnets stocked at AIMS for industrial use comply with AS 4991:2004 Lifting Devices, the Australian standard governing below-the-hook lifting equipment. Each unit carries an AS 4991 stamp, manufacturer name, SWL, minimum plate thickness, serial number, and ships with an individual test certificate. Magswitch additionally certifies to ISO 9001 quality management. Australian principal-contractor sites typically reject lifting equipment that carries only the European EN 13155 mark — AS 4991 is the AU site requirement. What happens to a lifting magnet if the power fails? Permanent and electro-permanent (Magswitch) lifting magnets are inherently fail-safe — they require no power during the lift. The magnetic field is generated by permanent rare-earth magnets, and the switching mechanism is purely mechanical. Power loss has no effect on the magnetic adhesion. Electromagnet lifters are not fail-safe — they require continuous current during the lift, and power loss causes the field to collapse and the load to drop. For this reason, AU industrial sites overwhelmingly choose permanent or electro-permanent technology. Where electromagnets are used (very high capacity, scrap handling), battery backup systems are mandatory. How hot can a lifting magnet get before losing capacity? Most rare-earth (neodymium-iron-boron) permanent magnets used in industrial lifting magnets begin to lose magnetic strength above 80°C and lose strength dramatically above 120°C. Standard-grade neodymium magnets are rated to 80°C max operating temperature; high-temperature variants (SH, UH grades) reach 150°C. Loads coming straight from welding, heat treatment, hot-rolling, or annealing must cool to below the magnet's max temperature before lifting. The data plate specifies the maximum operating temperature for the unit — exceed it and capacity is unreliable. Can I rig a multi-leg sling to a single lifting magnet? No — not without a spreader bar between the slings and the magnet. Multi-leg slings applied directly to a single magnetic lifter's lifting eye apply pry forces at angle to the base plate; the lifter base wants to peel off the load, defeating magnetic adhesion. The correct rig is a single vertical line from the hoist to the magnet's lifting eye, or two/more magnets attached to a rated lifting beam (spreader bar) with the slings connecting from the beam to the load. Same rule applies to beam clamps and plate clamps. Does a lifting magnet damage the load surface? Generally no. The base of a lifting magnet contacts the load over a flat area with no biting teeth, no clamping pressure, and no edge contact. Surface marks from a lifting magnet are typically minimal — magnetic residue (which wipes off) and possible light contact marks if the base is dragged across the load. For finished or polished steel surfaces, the lifter is gentler than a toothed plate clamp. The exception is if the lifter is dropped onto the load (mechanical damage from impact) or if magnetic particles contaminate the load surface — relevant for some food-grade and pharmaceutical applications. What's the difference between Magswitch MLAY 600 and MLAY 1000? The MLAY 600 is rated 600 lb (272 kg) SWL per cell on ≥15mm flat steel; the MLAY 1000 is rated 1,000 lb (454 kg) SWL per cell on ≥25mm flat steel. Both use the same electro-permanent technology but the MLAY 1000 has larger rare-earth magnets, a heavier base plate, and requires thicker plate to develop full SWL. The MLAY 600 is the choice for medium-capacity work on plate around 15-20mm; the MLAY 1000 is the choice for heavier capacity on plate ≥25mm. Both ranges scale by adding cells in line — 1×, 2×, 3×, 4× configurations multiply the single-cell SWL. Can a lifting magnet pick up aluminium, brass or copper? No. Aluminium, brass, copper, lead, zinc, tin, titanium, and most non-iron metals are non-magnetic and will not be picked up by any lifting magnet regardless of capacity. The magnetic field cannot grip non-ferrous materials. For aluminium plate handling, use plate clamps or vacuum lifters. For aluminium sheet, vacuum lifters with smooth-surface cups are the standard tool. For brass, copper, or other non-ferrous metals, slings around the load through lift holes or rigged in a basket configuration are the typical method.

People Also Ask — Magnetic Lifters Q: What is a magnetic lifter? A magnetic lifter is a handling device that uses permanent or electro-permanent magnetic force to pick up and move ferromagnetic materials such as steel plate, blocks, and billets. Magnetic lifters eliminate the need for slings, clamps, or through-holes in the workpiece — the magnet attaches directly to a flat ferromagnetic surface, making them ideal for thin plate, precision parts, and situations where conventional rigging would damage the surface. Q: What is the difference between a permanent magnet lifter and a Magswitch? A traditional permanent magnet lifter uses a lever or handle to align or misalign fixed permanent magnets to turn the holding force on and off. A Magswitch uses electro-permanent technology — a brief electrical pulse reorients internal permanent magnets to switch holding force on or off, but no power is required to maintain the magnetic circuit. This means Magswitch lifters retain their hold even if power is lost during a lift, unlike electromagnets which release when power fails. Q: What is the difference between SWL and pull-off force for magnetic lifters? The Safe Working Load (SWL) is the maximum load the lifter should be used to lift under safe working conditions, accounting for a safety factor (typically 3:1 to 5:1). The pull-off force is the maximum force measured in a laboratory test before the magnet releases. Because real-world conditions — surface finish, plate thickness, air gaps from rust or paint, and side-loading — reduce effective holding force, the SWL will always be substantially lower than the maximum pull-off force. Q: What materials can a magnetic lifter pick up? Magnetic lifters work only on ferromagnetic materials — mild steel and iron are the primary targets. Aluminium, copper, brass, titanium, and non-metallic materials such as plastic, wood, and concrete are non-magnetic and cannot be lifted. Stainless steel varies by grade — austenitic grades (304, 316) are generally non-magnetic, while ferritic and martensitic grades can be magnetic, though holding force may be reduced compared to mild steel. Q: What plate thickness is required for magnetic lifting? As a general rule, the steel plate needs to meet the lifter's specified minimum plate thickness — typically 10–20mm for medium-duty lifters. Thin plate does not provide a complete magnetic circuit, which dramatically reduces effective holding force. Some Magswitch models publish working loads for different plate thickness ranges, and the rated SWL applies only when the minimum plate thickness is met on a clean, flat surface.

If you lift loads in an Australian workshop, fabrication shop, or on a construction site, you'll reach for a sling almost every day. Three types do almost all the work: chain slings for heavy-duty production lifting, wire rope slings for high-temperature and abrasive environments, and synthetic slings — the webbing and round slings covered in this guide — for almost everything else. Synthetic slings are the most-used sling type in AU industry. They're light, flexible, gentle on painted and machined surfaces, and rated to AS 1353 (webbing) or AS 4497 (round) with an 8:1 safety factor. A 1-tonne webbing sling weighs about 350 grams; a 1-tonne chain sling weighs over 4 kilograms. The trade-off is abrasion sensitivity — a synthetic sling that's been dragged across a sharp edge or chemical-soaked is finished, where a chain sling would shrug it off. This guide covers webbing (flat) slings and round slings — the two synthetic-sling formats — for Australian industrial lifting. We'll cover construction, the AS 1353 + AS 4497 standards framework, the WLL colour-code chart, hitch types and deration, inspection and retirement criteria, and where each format wins. AIMS stocks the full range across Austlift, Beaver, Garrick Herbert, and Yoke — 100+ SKUs. Browse the rigging and lifting slings range or call (02) 9773 0122 for sizing help. For chain slings see our Chain Sling Guide; for wire rope slings see the Wire Rope, Slings & Rigging Guide. This article is the third in the slings triple — synthetic webbing and round slings, both governed by AS 1353 and AS 4497. What synthetic slings are — webbing vs round Synthetic slings are flexible textile lifting devices made from high-tenacity polyester yarn. Two formats dominate the AU market: Webbing (flat) slings are woven polyester webbing — flat, ribbon-like, with sewn loop eyes at each end (or sewn endless for the rarer endless variant). The webbing is usually constructed in 1, 2, or 4 plies of webbing layered together — a 4-ply sling at the same WLL is shorter and stiffer than a 1-ply sling, but more abrasion-resistant. Most operators recognise webbing slings as the "flat blue/green/yellow lifting straps" they see on workshop walls and at builders' yards. Round slings are continuous loops of polyester core fibres encased in a woven polyester jacket. The jacket protects the core from abrasion; the core takes the load. Round slings are even more flexible than webbing — they conform around odd-shaped loads, distribute load evenly across multiple pickup points, and are softer on painted or polished surfaces. Heavy-duty round slings (Beaver Jumbo and Mega ranges) are how 30-, 50- and even 100-tonne loads get lifted in modular construction and heavy industry. Both formats sit alongside chain slings and wire rope slings in the AU rigging toolbox. The slings triple — chain (covered in our Chain Sling Guide), wire rope (covered in our Wire Rope, Slings & Rigging Guide), and synthetic (this guide) — covers the vast majority of below-the-hook lifting. Synthetic slings own the day-to-day workshop and trade applications; chain wins on heavy production duty cycles; wire rope wins on heat and severe abrasion. Webbing (flat) slings — construction and anatomy A flat webbing sling is woven polyester webbing fabricated to AS 1353.1 specifications. The most common construction is 100% high-tenacity polyester yarn woven in standard widths (25mm, 50mm, 75mm, 100mm, 150mm, 200mm, 240mm, 300mm), folded back at each end to form a sewn loop eye, and layered into 1-ply, 2-ply, or 4-ply configurations to achieve the rated capacity. The key parts: Body — the main length of webbing that takes the load. Width and ply count combine to set the WLL. Eyes — sewn loops at each end. Standard folded eyes for general-purpose use; reinforced or "twisted" eyes for harder-wearing applications. Sewing — multi-stitch box patterns at the eye joins. The stitching is the weakest point on the sling — a healthy stitch pattern is the inspection focus. Tag — sewn-in label with WLL, manufacturer, AS 1353 reference, serial number, length and date of manufacture. The tag is the legal certificate; if it's illegible, the sling is out of service. Ply count matters: a 2-tonne 1-ply sling and a 2-tonne 2-ply sling have the same vertical WLL but different bend characteristics. The 2-ply is shorter for the same nominal length, less flexible, and harder-wearing. A 1-ply Beaver Flat Webbing Sling 1-Ply is the lighter, more flexible choice for clean workshop work; a 2-Ply or 4-Ply Beaver sling steps up for harder duty. The Garrick Flat Webbing Sling range is the AU mid-tier — 1-ply construction, full 1T to 10T+ capacity range, AS 1353 compliance, sewn-in tag with serial number. Browse the full webbing sling range for the size and capacity you need. Round slings — construction and anatomy A synthetic round sling looks like a continuous polyester loop — there are no visible eyes, no sewn ends. Inside the woven polyester outer jacket, a continuous core of polyester yarns runs in a single endless loop. The number of core yarns determines the capacity; the jacket is purely abrasion protection — it doesn't carry load. Construction is governed by AS 4497.1. Manufacturers wind a continuous polyester yarn around a fixed length to build up the core to the rated capacity, then enclose the core in a woven jacket sleeve. The jacket is colour-coded by capacity (we'll cover the chart below), and a sewn-in label provides the legal WLL, manufacturer, serial number, length, and AS 4497 reference. The key parts: Core — the polyester yarn loop that takes the load. Hidden inside the jacket. Jacket — the woven polyester sleeve. Colour-coded for WLL (1T violet, 2T green, 3T yellow, etc.). Provides abrasion protection. Tag — same data as a webbing sling tag. Sewn into the jacket. The big advantage: round slings cradle a load with a rounded, soft contact area. Webbing slings squeeze a load between two flat surfaces; round slings flow around the load. For odd-shaped or coated loads — castings, finished machinery, fragile fabrications, painted assemblies — the round sling is gentler and more secure. The trade-off is that the jacket can hide internal core damage; an abraded jacket is obvious, but shock-loading or chemical exposure can damage the core without leaving visible jacket marks. AIMS stocks the full Austlift range across all common WLLs: Austlift Round Sling 1-Tonne (Violet) — workhorse light-duty option, 0.5m to 8m lengths. Austlift Round Sling 2-Tonne (Green) — the most-used WLL in AU industrial work. Austlift Round Sling 3-Tonne (Yellow) — step-up for heavier loads. Austlift Durabone Round Sling 2-Tonne — heavy-duty jacket variant for high-abrasion environments. Garrick Round Sling 5-Tonne (Red) — mid-tier 5T option. Beaver Mega Round Sling 6-Tonne (Brown) — heavy-duty premium tier. Beaver Jumbo Round Sling 30-Tonne — for modular construction, transformers, and other heavy industrial lifts. Webbing vs round — when to use each Both work. Both are AS-compliant. Both come in the same WLL range. The decision usually comes down to load shape, surface sensitivity, and how harsh the environment is. Choose webbing (flat) when Choose round when Load has flat parallel surfaces (boxes, crates, bundles, beams) Load has curved, irregular, or rounded surfaces (castings, vessels, tanks) Visual abrasion inspection matters — webbing shows damage clearly Surface protection matters — finished/painted/polished surfaces You need a wide bearing area to spread load on soft material You need maximum flexibility for complex multi-leg setups Heavier-duty cycle work (4-ply construction is more abrasion-resistant) Frequent re-rigging — round slings stow into smaller bundles Lower price point at equivalent WLL — typical for trade and maintenance Choker and basket hitches that need to flex tightly around the load In real workshops, most operators have both. A 2T webbing sling and a 2T round sling cover 80% of day-to-day lifting between them. The forum consensus from r/Rigging and Practical Machinist machine-shop threads matches this: webbing for boxes and beams, round for castings and machinery. AS 1353 + AS 4497 — Australian standards explained Two Australian Standards govern synthetic slings: AS 1353.1-1997 Flat synthetic-webbing slings (Product specification). Sets the design, materials, construction, marking and testing requirements for webbing slings sold in Australia. AS 1353.2-1997 Flat synthetic-webbing slings (Care and use). Covers correct use, inspection, retirement criteria and operator responsibilities. AS 4497.1-1997 Round slings — synthetic fibre (Specification). Equivalent design and testing standard for round slings. AS 4497.2-1997 Round slings — synthetic fibre (Care and use). Equivalent care-and-use standard for round slings. Both standards mandate a safety factor of 8:1 — meaning the minimum breaking load (MBL) of the sling is at least 8 times the marked WLL. A 1-tonne sling has an MBL of at least 8 tonnes. This is much higher than the 4:1 or 5:1 typical for chain slings — the higher safety factor compensates for synthetic slings' greater sensitivity to damage and shock loading. Compliant slings supplied in Australia are individually serial-numbered, NATA-tested, and supplied with a test certificate. Look for the AS 1353 (webbing) or AS 4497 (round) reference printed on the sewn-in tag along with the manufacturer name, WLL, length, serial number, and date of manufacture. If any of those data points is missing or illegible, the sling is out of service until re-certified by a competent person. For the broader WLL/SWL/MBL framework — what each acronym means and how they relate — see our SWL meaning explainer. The colour-code chart — WLL by jacket colour One of the most-cited features of synthetic slings is the standardised colour code. Every round sling jacket and every webbing sling label uses the same colour-by-WLL scheme across AU and global markets, harmonised with EN 1492 (the European equivalent). At a glance, an experienced rigger reads the WLL off the colour without picking the sling up. Jacket colour WLL Common uses Violet 1 tonne Light-duty workshop, hand tools, small assemblies, test rigs Green 2 tonnes General workshop and trade work — the most-used WLL in AU industry Yellow 3 tonnes Maintenance lifts, mechanical assemblies, structural fabrications Grey 4 tonnes Heavier maintenance, light structural steel, machinery transport Red 5 tonnes Structural steel, large machinery, motors and gearboxes Brown 6 tonnes Pipe sections, vessels, heavy mechanical assemblies Blue 8 tonnes Modular construction, structural sections, transformers Orange 10 tonnes and above Heavy industrial — pre-cast panels, transformers, vessels, modular plant For higher capacities (12T, 15T, 20T, 30T+) the orange code continues, with the WLL printed on the tag. The Beaver Jumbo and Mega Round Sling ranges cover 6T to 50T+ in orange jackets, with the precise WLL on the tag. Critical: the colour is a starting point, not a substitute for reading the tag. Always confirm the WLL by reading the sewn-in tag before the lift. A jacket that's been replaced (it happens with re-jacketed slings on rare occasions) or a tag that's been bleached by UV may not match. The tag is the legal document; the colour is a fast cross-check. Hitch types — vertical, choker, basket The same sling rated to 2 tonnes can be safely loaded to anything from 1.6 tonnes to 4 tonnes depending on how you rig it. Understanding the three hitch types and their derating factors is the difference between a safe lift and an overload. Vertical hitch (1.0×). The sling hangs straight down from the hook with both eyes attached to a single load point or a shackle. WLL is the rated value. This is the baseline. Choker hitch (0.8×). The sling is wrapped around the load, then one eye is passed through the other, forming a self-tightening loop. The sling tightens on itself as the load is lifted. WLL drops to 80% of vertical because of the bend angle at the choke point. The forum consensus from r/Rigging and r/cranes is consistent: "if you choke, multiply by 0.8." Basket hitch (2.0×, parallel legs). The sling passes under or around the load, with both eyes attached up at the hook. The load hangs in a U or "basket" formed by the sling. With both legs vertical (parallel), capacity doubles to 200% — both legs share the load. As the basket angles spread (the legs come apart at the top), capacity derates by the sling-angle factor — the same maths as a 2-leg sling. Hitch WLL multiplier Notes Vertical (single line) 1.0× Baseline. Both eyes attached to a single point or shackle. Choker 0.80× Self-tightening loop around the load. Sharp bend at the choke reduces WLL. Basket — parallel legs (both vertical) 2.0× Both legs share load equally. Maximum capacity for a single sling. Basket — 60° from horizontal 1.732× 2 × sin(60°) = 1.732. Standard rigging angle. Basket — 45° from horizontal 1.414× 2 × sin(45°) = 1.414. Wide spread — confirm sling length is sufficient. Basket — 30° from horizontal 1.0× 2 × sin(30°) = 1.0. Same as a single vertical line — and not recommended. The rule riggers live by: 60° from horizontal is the practical minimum. Below 60° (more horizontal sling angle), capacity loss is severe and side loads on attachment points climb fast. Below 45° you've lost more than 30% of capacity and you're applying significant inward force on the lifting points. Below 30° you've thrown away half the capacity and the geometry is dangerous. For more on sling angle deration and the 60° rule, see our Chain Sling Guide sling-angle section — the maths is identical for chain, wire rope and synthetic slings. Reading the sling tag — what it tells you Every compliant sling has a sewn-in tag. The tag contains the legally-required information for use: WLL in vertical, choker and basket configurations — three numbers on a single tag. Vertical is the baseline; choker is 0.80× the vertical; basket is 2.0× the vertical (parallel legs). Manufacturer name and country of origin. AS 1353 (webbing) or AS 4497 (round) reference. Serial number. Ties the sling to its individual test certificate. Length. Usually printed in metres. Date of manufacture. Used to track service life — 10 years is the typical hard limit, less in harsh environments. Material code. "PES" = polyester (the AU industrial standard). "PA" = polyamide (nylon). "PP" = polypropylene (rare, lower temperature limit). If any of those data points is missing or illegible, the sling is out of service until re-certified. Bleached, faded, ripped, or covered tags are common failure modes — UV exposure, paint over-spray, abrasion, and chemical contact all kill tags. Replacement tags are available from manufacturers but must be authorised — a sling without traceability cannot be used safely on a regulated site. Pre-use inspection — the hand-feel rule The inspection rule for synthetic slings is different from chain or wire rope: visual inspection alone is not enough. The forum consensus from professional riggers is consistent — you must hand-feel the entire length of the sling for each pre-use check. Run the sling through your gloved hands, feeling for: Cuts in the webbing or jacket. Any cut that severs even a single fibre means retire — the load-bearing yarns may be damaged below. Abrasion that's reduced webbing thickness. Significant fluffing, fuzz or fibre loss = retire. Heat damage. Brittle, hard, glossy patches indicate heat exposure (welding splatter, hot work nearby). Polyester degrades from about 100°C; melted polyester is brittle and weak. Chemical attack. Stiff, discoloured, or chalky patches indicate acid, alkali, or solvent exposure. UV damage. Sun-bleached, faded, brittle webbing = the polyester chains have broken down. Common on slings stored on outdoor racks. Stitch damage. Broken, missing, or pulled stitches at the eye joins. Stitch failure is the most common catastrophic failure mode. Knots or kinks. A kinked synthetic sling is permanently damaged. Knots reduce capacity to ~50% and damage the fibres. Internal core damage on round slings. If the jacket is intact but you can feel a discontinuity, lump, or thinning in the core through the jacket, retire the sling. Inspection level Frequency By whom Pre-use visual + hand-feel Every lift Operator (dogger or competent person) Periodic thorough inspection Every 3 months (light duty) to every month (heavy duty) Competent person, recorded Annual NATA proof-test Annually (most regulated sites) or per the company lifting register NATA-accredited test facility Retirement criteria — when to scrap a sling Synthetic slings retire on damage, not on age alone (though most manufacturers specify a 10-year hard maximum from date of manufacture, even on slings that look unused). The conditions that mandate immediate retirement: Any cut through the webbing or jacket exposing core fibres. Significant abrasion with visible fibre loss. Heat or chemical damage — brittle, hard, discoloured, or chalky patches. UV degradation — fading and brittleness. Knots or kinks — permanent fibre damage even after the kink is straightened. Broken or missing stitches at the eyes. Tag illegibility — no traceable WLL or serial number. Shock load — any sling that's been shock-loaded (sudden drop, snatch lift, severe arrest) must be inspected by a competent person before further use; the hidden core damage cannot be ruled out by visual inspection alone. Overload — any sling loaded above its WLL is condemned. The UK LOLER inspector rule applies as a principle: a sling that's been at twice its rated load is finished. Manufacturer's stated service-life limit reached (typically 10 years from manufacture). Cut a retired sling in half so it can't be returned to service by mistake, and remove the tag. This is standard AU rigging practice and is required under several site-specific lifting registers. Edge protection — sleeves, corner protectors, burlap Synthetic slings die fast at sharp edges. Steel plate edges, casting fettle marks, machined corners, even rough timber edges can cut a sling in a single lift. Edge protection is the standard mitigation. Three options: Slip-on protector sleeves. Heavy-duty leather, Cordura, or polyurethane sleeves that slide over the sling at the contact point. Reusable, fast to fit, cover the full circumference. Corner protectors. Rigid plastic or steel V-blocks that sit between the sling and the load corner. Better for sharp 90° angles where a sleeve would still be cut at the apex. Disposable wraps — burlap, hessian, cardboard, even old timber offcuts. Common on field jobs where dedicated protectors aren't to hand. Forum-validated insight (r/Rigging): The reason riggers wrap burlap or hessian under a sling at a contact point isn't softening — it's increasing the bend radius. Polyester slings have a manufacturer-specified minimum bend radius for full WLL. A sharp edge with no protection forces the bend below the minimum and damages the fibres immediately. Burlap or a similar wrap distributes the bend across a larger radius and keeps the sling within spec. Most riggers don't articulate this; the experienced ones do. Sling connectors — terminal fittings and hooks Synthetic slings often need a hook, master link, or connector at the eye end. AIMS stocks two common Yoke products plus the Austlift G80 connector: Yoke G100 Webbing Sling Connector 8mm — Grade 100 alloy steel connector designed to attach a chain hook or master link to a webbing sling eye without damaging the webbing. Yoke G80 Round Sling Connector — designed for the rounded geometry of a round sling, prevents jacket abrasion at the connector. Austlift G80 Type WL Webbing Sling Connector — Grade 80 alloy steel, specifically shaped for webbing sling eye geometry. The wrong connector kills slings. A sharp-edged shackle pin pulled directly through a webbing sling eye creates a stress concentration and can cut the webbing under load. A purpose-designed sling connector spreads the load across a wider, smoother contact area. For shackles attached directly to sling eyes, see our Bow Shackle and D-Shackle Guide — the pin-orientation rules apply equally to chain, wire and synthetic slings. 1-ply, 2-ply, and 4-ply webbing — what the difference means Webbing slings are constructed in single, double, or quadruple plies of webbing layered together at sewn eyes. Same webbing material, same polyester, same AS 1353 — but different stack-up. Construction Characteristics Best for 1-ply (single layer) Lightest, most flexible, longest at given WLL, easiest to inspect — abrasion shows immediately on the single layer Workshop and trade work, clean environments, frequent re-rigging, Beaver 1-Ply 2-ply (double layer) Mid-weight, mid-flexibility, more abrasion resistance than 1-ply at same WLL, shorter overall length General industrial duty, mixed-environment work, Beaver 2-Ply 4-ply (quadruple layer) Heaviest, stiffest, shortest at given WLL, most abrasion-resistant — significantly more durable in harsh environments Heavy industrial, high-cycle hire fleet, abrasive environments, Beaver 4-Ply For the same WLL, a 4-ply sling has roughly 4× the cross-section of a 1-ply sling — making it shorter, stiffer, and tougher on the wear faces. For a workshop wanting the lightest, most flexible 1-tonne sling, the 1-ply is the choice. For a hire fleet or a high-abrasion environment, the 4-ply pays for itself in service life. AIMS synthetic sling range AIMS stocks 100+ webbing and round sling SKUs across the four AU brands most riggers trust: Austlift — AS 1353 / AS 4497 compliant, 100% polyester yarn, individual test certificates, full 1T to 30T+ range. AIMS stocks the entire core Austlift round sling series (1T, 2T, 3T, 4T, 5T at standard lengths 0.5m to 8m) plus the heavy-duty Austlift Durabone Round Sling for high-abrasion work and the G80 Type WL Webbing Sling Connector. Beaver — premium AU rigging brand. 1-Ply, 2-Ply and 4-Ply flat webbing slings, the Flat Endless Sling for choker and basket work without eye joins, plus the Mega Round Sling (6T to 8T) and Jumbo Round Sling (30T to 50T+) for heavy industrial lifts. Garrick Herbert — AU manufacturer with the Garrick Flat Webbing Sling (1T to 10T+, AS 1353, 8:1 safety factor) and the Garrick Round Sling 5-tonne (Red). Yoke — Grade 80 and Grade 100 connectors. The G100 Webbing Sling Connector and the G80 Round Sling Connector are the trusted hardware for connecting slings to chain hooks, master links and shackle assemblies.

Specialty slings — drum, pipe, jumbo Beyond the standard webbing and round-sling ranges, several specialty types fill specific applications: Drum slings — purpose-shaped slings for lifting 200L drums vertically. Cradle the drum body without crushing the chime. CPC $110 on "drum lifting sling" — these are real-world specialty products. Pipe slings — wider webbing or larger-diameter round slings rated for cylindrical loads with even load distribution. Endless slings — round slings or sewn-endless webbing slings (no eye joins). The Beaver Flat Endless Sling is the AU example. Useful for choker and basket hitches where eye joins would interfere. Jumbo round slings — heavy-duty industrial round slings rated 30T, 50T, 100T+. Used in modular construction, transformer lifts, vessel placement, and pre-cast panel handling. The Beaver Jumbo Round Sling series covers this end of the market. Anti-static slings — for environments where electrostatic discharge is a hazard. Specialised order, typically polypropylene rather than standard polyester. For specialty configurations not in the standard catalogue, contact us — most can be sourced or fabricated to AS 1353 / AS 4497 specifications with NATA test certification. Common mistakes From hundreds of forum threads and AU rigging incident reports, the same handful of mistakes show up repeatedly. Every one of them is preventable. Mistake Why it fails Fix Knotting a too-long sling to shorten it Knots reduce sling capacity to ~50% and damage fibres permanently. The kink point becomes the failure point. Use a shorter sling, doubled-up sling, or a chain shortening clutch. Using a sling around a sharp edge with no protection Bend radius drops below manufacturer spec; fibres cut under load. Slip-on sleeve, corner protector, or wrap (burlap, hessian, cardboard). Choker hitch loaded at vertical WLL (forgotten 0.8× derate) Effective WLL is 80% of vertical. Loading to 100% is a 25% overload. Read the tag — vertical, choker and basket WLLs are all printed. Basket hitch with sling angle below 60° (legs too horizontal) Severe WLL deration plus inward side-load on attachment points. Use a longer sling, two slings, or a spreader/lifting beam. Soft-on-soft rigging (synthetic against synthetic) Mutual abrasion at the contact point under load. Both slings damaged in one lift. Insert a master link, hook or shackle between the two synthetic slings. Sharp-edged shackle pin through webbing sling eye Stress concentration at the pin contact area. Webbing cuts under load. Use a sling connector (Yoke G100, Austlift G80) sized for the sling format. Returning a shock-loaded sling to service Internal core damage on round slings cannot be ruled out by visual inspection. Out of service until a competent person inspects, or scrap. Storing slings on outdoor racks in direct sunlight UV breaks down polyester chains. Sling becomes brittle with reduced WLL. Store indoors, on hooks or hangers, away from direct sunlight, chemicals and damp. Selection checklist + how to order A practical pre-order checklist: Know the load weight — and the WLL needed at the hitch type you'll use (vertical / choker / basket). Choose webbing or round — flat surface vs irregular load, abrasion environment vs surface protection. Pick the WLL by colour — violet 1T, green 2T, yellow 3T, grey 4T, red 5T, brown 6T, blue 8T, orange 10T+. Pick the length — long enough for the hitch geometry without forcing knots or overly horizontal angles. Standard lengths 0.5m, 1m, 1.5m, 2m, 3m, 4m, 6m, 8m. Pick the ply count (webbing only) — 1-ply for clean, 2-ply for general industrial, 4-ply for heavy duty / abrasive. Confirm AS 1353 (webbing) or AS 4497 (round) — every AIMS-supplied sling is compliant and individually serial-numbered. Plan edge protection — sleeves, corner protectors or wraps if there are sharp edges in the load path. Check operator licensing — dogging or rigging licence as required by the WHS framework. Slinging loads is dogging activity under CPCCLDG3001. For multi-leg sling assemblies, see our Chain Sling Guide — the multi-leg geometry rules apply equally to synthetic configurations. For complete rigging context including shackles and connection hardware, see our Wire Rope, Slings & Rigging Guide and Bow Shackle Guide. For overhead lifting points, see our Beam Clamp Guide. Frequently Asked Questions What is a webbing sling used for? A webbing sling is a flexible polyester lifting strap used to attach a load to a chain block, electric hoist, crane hook, or other lifting device. Common uses include lifting machinery for transport, suspending loads from beam clamps for maintenance work, supporting fabricated assemblies during welding, and general workshop and trade lifting where a chain sling would be too heavy or damage the load surface. What is the difference between a round sling and a webbing sling? A webbing sling is flat, ribbon-like polyester webbing with sewn loop eyes at each end. A round sling is a continuous polyester core inside a woven jacket — no visible eyes, just an endless loop. Webbing slings have visible damage modes (abrasion, cuts, broken stitches show clearly); round slings hide internal damage under the jacket and are gentler on finished surfaces. Both are AS-compliant with an 8:1 safety factor. What is the safety factor of synthetic slings in Australia? AS 1353 (webbing) and AS 4497 (round) both mandate an 8:1 safety factor — the minimum breaking load (MBL) of the sling is at least 8 times the marked Working Load Limit (WLL). A 1-tonne sling has an MBL of at least 8 tonnes. The 8:1 factor is higher than the 4:1 typical for chain slings, reflecting synthetic slings' greater sensitivity to damage. What does AS 1353 cover? AS 1353 covers flat synthetic-webbing slings in two parts: AS 1353.1-1997 is the product specification (design, materials, construction, marking, testing); AS 1353.2-1997 is care and use (correct use, inspection, retirement criteria, operator responsibilities). Compliant webbing slings sold in Australia are individually serial-numbered with a sewn-in tag carrying the AS 1353 reference, manufacturer name, WLL, length and date of manufacture. What does AS 4497 cover? AS 4497 covers synthetic round slings in two parts: AS 4497.1-1997 is the product specification; AS 4497.2-1997 is care and use. AS 4497 is the round-sling equivalent of AS 1353 — same 8:1 safety factor, same colour-code system, same care and inspection framework. The two standards are usually treated together in AU rigging documentation. What is the colour code for lifting slings in Australia? The AU/NZ colour code matches the global EN 1492 system: 1-tonne violet, 2-tonne green, 3-tonne yellow, 4-tonne grey, 5-tonne red, 6-tonne brown, 8-tonne blue, 10-tonne and above orange. The colour identifies the WLL at a glance, but the legal WLL is on the sewn-in tag and must always be read before the lift. Bleached or replaced jackets can mismatch the original WLL. What is a 2-tonne sling colour? Green. Across both webbing slings and round slings in Australia, a 2-tonne WLL is marked with green webbing or a green jacket. This is the most-used WLL in AU industrial work and the colour most operators recognise immediately. How does the choker hitch reduce sling capacity? A choker hitch wraps the sling around the load and passes one eye through the other to form a self-tightening loop. The sling bends sharply at the choke point, creating a stress concentration that reduces effective WLL to 80% of the vertical rating (multiply vertical WLL by 0.80). The 0.8× factor is a long-standing rigging industry standard and applies equally to chain, wire rope and synthetic slings. How does the basket hitch increase sling capacity? A basket hitch passes the sling under or around the load with both eyes attached up at the lifting point. With both legs vertical (parallel), the load is shared equally between two lines, doubling effective capacity to 200% of vertical (2.0×). As the basket angles spread (legs come apart at the top), capacity derates by the sling-angle factor. At 60° from horizontal the multiplier is 1.732×; at 45° it's 1.414×; at 30° it's back to 1.0× and the geometry is unsafe. What sling angle puts the least stress on the slings? The closer to vertical, the lower the stress per leg. A two-leg sling at 90° from horizontal (straight vertical legs) puts only the load weight per leg through each sling. At 60° from horizontal, leg load increases to 58% of total per leg. At 45° it's 71% per leg. At 30° it's 100% per leg — each sling is carrying the full load weight even though the lift is shared between two. The AU rigging rule of thumb: 60° from horizontal is the practical minimum. How often should I inspect a webbing or round sling? Pre-use visual and hand-feel inspection before every lift, by the operator. Periodic thorough inspection every month to three months by a competent person, recorded in a lifting register. Annual NATA proof-test by an accredited test facility, or per the company's lifting-equipment register requirements. Most regulated AU sites require quarterly thorough inspection on hire-fleet equipment. When should I retire a synthetic sling? Immediately, on any of these: any cut through the webbing or jacket; significant abrasion with fibre loss; heat or chemical damage (brittle, hard, discoloured patches); UV degradation (faded, brittle); knots or kinks; broken or missing stitches; illegible tag; shock-loaded; overloaded above WLL; or the manufacturer's stated service-life limit (typically 10 years from manufacture). Cut a retired sling in half so it can't be returned to service. Can I keep using a sling with a small cut? No. Any cut through the webbing or jacket exposing the load-bearing fibres mandates immediate retirement. Synthetic slings rely on every fibre being intact to develop their rated capacity. A small cut becomes a large failure under load — the cut is the propagation point. The forum consensus from AU and international rigging communities is unanimous on this. What's the difference between 1-ply, 2-ply and 4-ply webbing slings? The number of layers of webbing stacked at the eye joins. Same polyester material, same AS 1353 compliance, same WLL at given dimensions — but a 1-ply is the lightest and most flexible, a 2-ply is mid-weight and mid-flex, and a 4-ply is the heaviest, stiffest and most abrasion-resistant. Same WLL at higher ply count means a shorter, stiffer, more durable sling. 1-ply for clean workshop work, 2-ply for general industrial, 4-ply for heavy-duty or hire fleet. Are round slings stronger than webbing slings? At equivalent WLL, no — both meet the same 8:1 safety factor. Round slings are typically lighter and more flexible at the same WLL because the polyester core is concentrated rather than spread across a flat webbing. Round slings handle higher capacities at smaller cross-sections — the Beaver Jumbo Round Sling reaches 30T+ in a package that's still hand-handleable. For straight comparison at common WLLs (1T to 10T), the choice between webbing and round is about load shape and surface sensitivity, not strength. Need to identify a thread standard?

A webbing sling is a flat strap typically made from polyester or nylon woven in a flat band, with eyes at each end. It is strong, lightweight and distributes load over a wider contact area than wire rope. A round sling (also called an endless sling or soft sling) is made from continuous polyester yarn loops enclosed in a protective woven sleeve, giving it a round cross-section. Round slings generally have higher load capacity for their weight, are more flexible and easier to store, and conform well to irregular load shapes. Both are used for general rigging and lifting where the load surface must be protected. Q: How does the hitching configuration affect a sling's working load limit? The same sling has different working load limits depending on how it is rigged. A straight pull (vertical hitch) uses the sling's full rated capacity. A choker hitch, where the sling wraps around the load and passes through its own eye, reduces capacity to typically 80% of the vertical rating due to the angular loading at the choke point. A basket hitch, where the sling forms a U under the load with both eyes attached to the hook, increases effective capacity because two legs share the load — but only if the load is balanced and the legs are vertical. As leg angles increase, the load on each leg increases and the effective capacity decreases. Q: What inspections should I perform on a webbing sling before use? Inspect the full length of the sling for cuts, abrasions, tears, chemical damage, heat damage and UV degradation. On webbing slings, look for fraying or broken yarns across the width, end fitting damage, and any stitching failure in the eye sections. A sling with cuts across more than 10% of the width, or any broken structural yarns, must be removed from service. On round slings, inspect the outer sleeve for damage and look for yellow inner core fibres visible through the sleeve, which indicate the structural yarns inside are exposed. If in doubt, remove the sling from service. Q: Can synthetic slings be used with chemicals? Synthetic slings must not be used with chemicals that attack the fibre material. Polyester webbing and round slings resist many acids and bleaching agents but are attacked by strong alkalis. Nylon slings resist alkalis but are attacked by acids. Neither material should be used where prolonged exposure to fuel, oils or organic solvents is likely, as these can degrade the fibres. The sling manufacturer's chemical resistance guide should be consulted before use in any chemical environment. Contaminated slings that cannot be identified should be destroyed and replaced. Q: What colour codes are used for webbing sling load ratings? Webbing slings use a standardised colour coding system to identify their working load limit (WLL) rating: violet = 1 tonne, green = 2 tonnes, yellow = 3 tonnes, grey = 4 tonnes, red = 5 tonnes, brown = 6 tonnes, blue = 8 tonnes, and orange = 10 tonnes. Slings above 10 tonnes are typically individually tagged. These colour codes apply to the sling body; always confirm the WLL from the attached load tag as the definitive rating, particularly for older slings where colour identification may be affected by soiling.

Read moreBeam Clamp Guide: WLL Ratings & Steel Beam Sizes
A beam clamp turns an overhead steel beam into a temporary lifting point. Hook one onto an I-beam flange, attach a chain block to the shackle, and you have a 1-tonne to 10-tonne pickup point exactly where you need it — no welding, no drilling, no permanent fixtures. For maintenance fitters, mechanical workshops, riggers and dogmen across Australian industry, the beam clamp is one of the most cost-effective pieces of lifting kit in the toolbox. It's also one of the most misunderstood. The same word — "beam clamp" — is used for at least three different products: lifting beam clamps rated to AS 4991, hanging or suspension clamps for fixed services, and electrical conduit-support clamps that look similar but are not rated for any moving load. Pick the wrong one and you have a workplace incident waiting to happen. This guide covers beam clamps and girder clamps for lifting only — the lifting-rated devices stamped to AS 4991:2004, used with chain blocks, lever blocks, electric hoists and rigging assemblies on building sites, fabrication shops and maintenance workshops. We'll cover the fixed-jaw and universal screw-cam types AIMS stocks (Austlift, Beaver YC, Challenger and Garrick), how to size them for your beam, the side-loading rule that catches people out, beam trolleys, the dogger and rigger licensing context, and where beam clamps fail. Browse our beam clamp range or call (02) 9773 0122 if you need help selecting. What a beam clamp is — and what it isn't A lifting beam clamp grips the lower flange of a structural steel beam and provides a load-rated lifting eye, typically a shackle or D-ring, hanging below. The clamp transfers the load from the chain block, lever block or electric hoist into the beam, and the beam transfers it into the structure. It's a temporary fixture: clamp on, do the lift, unclamp, move on. It's not the same product as the orange threaded-rod beam clamp at the electrical supply house, or the cheap stamped-steel hanger clamp used to suspend conduit, water pipe or HVAC ducts. Those clamps are rated for static dead-loads — the weight of the service hanging from them — and not for the dynamic loads of a moving lift. A common Reddit thread shows an electrician using a threaded-rod beam clamp to suspend a hanging fixture; the consensus is blunt: that clamp is not rated for lifting use, even though it grips the same flange. The simple test: a lifting-rated beam clamp will be stamped with a Working Load Limit (WLL) in tonnes or kilograms, the standard it complies with (AS 4991 in Australia), the manufacturer name, a serial number, and the beam-flange thickness or width range it's certified for. If the only marking on a clamp is a thread size like "M12" or a generic max-load figure, it's a hanger clamp and should never go anywhere near a chain block. Warning — never improvise a lifting point. A pallet-puller, a piece of all-thread, an angle-iron offcut welded to the flange, or an unmarked clamp from the back of the shed is not a beam clamp. If the device is not stamped with a WLL and an Australian Standards reference, it does not get used to lift a load — full stop. Improvised or undocumented lifting attachments are one of the most common findings in NSW Resources falling-object reports. Beam clamp vs girder clamp — terminology "Beam clamp" and "girder clamp" describe the same product. The NSW Government dogging glossary uses "girder clamp" as the formal term, defining it as "an appliance designed to be fixed to the lower flange of a beam." Australian suppliers — Austlift, Beaver, Challenger, Garrick Herbert, Bullivants, Ranger Lifting — use the terms interchangeably across their catalogues. Search volume on Google AU is roughly three times higher for "beam clamp" than for "girder clamp," which is why this article leads with the more common term. What does matter is the distinction between a lifting beam clamp and a hanging or suspension beam clamp. A lifting clamp is rated for moving loads under a chain block or hoist — it has a shackle or fixed lifting eye, complies with AS 4991, and will be stamped with a WLL in lifting service. A hanging clamp is rated for static suspension only — fixed services, lighting bars, ductwork, conduit. Ratings on hanging clamps are a fraction of the equivalent lifting capacity, and the design assumes the load is centred and unmoving. Riley makes a Super Clamp model that bridges both applications, but it's the exception. Most clamps do one job, and using a hanging clamp under a chain block is a clear breach of the manufacturer's instructions. The four main types of beam clamp Lifting beam clamps come in four main configurations. Picking the right one is the first decision. Type How it works Best for AIMS example Universal screw-cam (adjustable) A screw thread plus a cam jaw. Tighten the screw to draw the cam against the flange. Wide adjustment range across many flange widths. Workshops with mixed beam sizes, hire fleets, general maintenance work. The most common type in AU industry. Austlift GC01, Beaver YC Fixed jaw with shackle Fixed jaw geometry sized to a specific flange range. Pre-fitted shackle for sling attachment. Faster on/off than screw type. High-cycle work where every lift uses the same beam. Faster to fit and remove than screw type. Challenger Beam trolley + girder clamp combo Wheels run on the lower flange. Hoist hangs from the trolley. The load travels along the beam. Workshop bays, machine shop pickup areas, anywhere the load needs to traverse the length of a beam. Beaver YC trolley clamp, Austlift trolley Suspension / hanging clamp Designed for static suspension. Lower WLL than lifting equivalents. Often no shackle — direct chain or wire attachment. Permanently or semi-permanently suspended services — lighting bars, conduit runs, mechanical services. NOT lifting. Specialist supply only — not stocked at AIMS for general lifting. For most general workshop and maintenance work the universal screw-cam type is the right choice. The 1-tonne Austlift GC01 at around $60 covers 75–220mm flanges and is rated to AS 4991 — most workshops have one in the lifting cabinet. Step up to the Beaver YC industrial range when you need a wider 90–320mm flange range, higher capacity (up to 10t), or premium-tier traceability. All beam clamps stocked at AIMS are AS/NZS load-rated with serial numbers and individual test certificates. The workhorse — Austlift GC01 deep-dive The Austlift Girder Clamp Model GC01 is the most common universal screw-cam clamp in Australian workshops. It's available across five WLL ratings — 1, 2, 3, 5 and 10 tonne — and covers a flange range of 75–220mm on the 1-tonne and progressively larger ranges on the higher-capacity sizes. Construction is alloy steel rated for use on flange materials up to 37 HRC hardness, individually serial-numbered with test certificates and a user manual supplied per unit. AS/NZS load-rated. The Austlift GC01 user manual states the device is "for vertical lift only" — meaning the load line must hang plumb beneath the clamp's lifting eye. This is the rule that catches people out. We'll cover the side-load problem and what it means for sling angles in the WLL section below. Austlift also supplies the Girder Clamp Black in 2-tonne capacity at around $76 — same operating principle, alternative finish. Either model is fit for general workshop and maintenance work where flange ranges sit in the typical AU structural steel sections (75–220mm covers most universal beam (UB) and universal column (UC) flanges in AS/NZS 3679.1 hot-rolled stock). Premium tier — Beaver YC industrial range The Beaver YC Industrial Girder Clamp is the premium-tier option AIMS stocks. WLL ratings span 1 to 10 tonne with a wider 90–320mm flange range than the equivalent Austlift unit, drop-forged alloy steel construction, AS 4991 compliance, and individual test certificates. The Beaver YC sits at a higher price point ($657 for the 1t at the time of writing) but it's the choice when: You're working on heavier structural sections — 250UB, 310UB, 360UB, 410UB and larger — where the standard 220mm Austlift jaw won't open wide enough. You need premium traceability for client documentation, compliance audits or principal-contractor tickets. You're running a hire fleet where build quality and inspection life matter against per-unit replacement cost. Beaver also supplies the YC Trolley & Girder Clamp combo — a 2000kg WLL trolley clamp with 72–200mm flange range that runs along the beam on rollers. Use the trolley combo where the load needs to traverse, not just lift in a single spot. Mid-budget — Challenger and Garrick Between the Austlift and Beaver tiers, AIMS stocks two mid-budget options. The Challenger Girder Beam Clamp covers the 1000–10,000kg WLL range at around $202 — solid working capacity, AS-compliant, suited to general workshop and trade applications where you want better than entry-level without paying the Beaver premium. Garrick Girder Clamp 10T at around $279 is purpose-built for the 10-tonne heavy-duty bracket — when capacity is the deciding spec, Garrick competes well against the equivalent Beaver YC 10t. For occasional workshop use, the Austlift GC01 is hard to beat on price-to-capability. For frequent lifting on a hire fleet or principal-contractor sites, the Beaver YC is the safe choice. Challenger and Garrick fill the middle. View the full beam clamp range to compare specs side by side. Beam range and flange thickness — sizing without shims Every beam clamp is rated for a specific flange-width range and a specific flange-thickness range. Get either wrong and the clamp either won't seat properly or will sit at the limit of its design envelope, where the safety margin disappears. The flange-width range is the dimension across the bottom of the I-beam — typically 75mm to 320mm in AIMS-stocked clamps, covering most structural sections in AS/NZS 3679.1. Australian universal beams (UB) and universal columns (UC) span 100mm to 410mm flange widths, so a single clamp won't fit every beam in a typical workshop. Mismatched sizing is a real-world problem: as one MEP engineer noted on Reddit, "even if you order the right size half the time the supply house sends you the wrong one." The mistake is to use a washer or steel plate as a shim to make a too-large clamp fit. That changes the load path, can twist the jaw, and is not approved by any manufacturer. AU section Flange width Suitable AIMS clamp 100UB / 100UC / 150UB 100–155mm Austlift GC01 1–3t (75–220mm) 200UB / 200UC / 250UB 133–204mm Austlift GC01 or Beaver YC 1–3t 310UB / 310UC 165–305mm Beaver YC 5t (90–320mm) 360UB / 410UB 170–235mm Beaver YC 5–10t If you're not sure of the flange dimensions, measure with a ruler or vernier caliper before you order. Drawing nominations like "200UB" don't tell you the actual flange width — a 200UB18.2 has a 99mm flange while a 200UB29.8 has a 134mm flange. Measure first. WLL, side-load deration and the sling-angle problem Every beam clamp is rated for vertical loading only unless the manufacturer explicitly states otherwise. The Austlift GC01 user manual is unambiguous: "Can only be used on vertical lift." Beaver, Challenger and Garrick clamps in the AIMS range are the same — the WLL stamped on the clamp applies when the load line hangs plumb beneath the lifting eye. Pull the load off-vertical and you're operating outside the rating. The two-leg sling trap. The single most common dangerous misuse of a beam clamp in Australian workshops is using one clamp as the suspension point for a two-leg or four-leg sling assembly. Each sling leg pulls at an angle to vertical. Those off-vertical components apply a side load to the clamp jaw — the clamp wasn't designed for it, the WLL drops dramatically, and the failure mode is the clamp slipping or rotating off the flange under load. The correct solution is a lifting beam (spreader bar) hung below the clamp, with the slings attached to the beam, not the clamp. A few specialist clamps — Tiger BCU and similar — are rated for loading at angles up to 90 degrees from vertical without deration. These are the exceptions. Unless your clamp's data plate explicitly says it can be loaded off-vertical, treat it as vertical-only. If a load can't be slung vertically beneath a single beam clamp, the standard AU rigging solution is a lifting beam (spreader bar) hung from the clamp via a single vertical chain or wire-rope sling. The lifting beam has multiple pickup points along its length, and the slings to the load attach to the beam. The clamp now sees a single vertical line — exactly what it's rated for. We cover spreader-beam selection in the lifting beam section below. Australian standards: AS 4991 + AS 1418.2 Two Australian Standards govern beam clamps and beam trolleys: AS 4991:2004 Lifting devices. The primary compliance standard for beam clamps used in lifting service. Covers design, manufacture, testing, marking and inspection of below-the-hook lifting devices including girder clamps, plate clamps and lifting magnets. Every lifting beam clamp sold in Australia for site or workshop use should carry an AS 4991 stamp. AS 1418.2 Cranes — Serial-hoists and beam trolleys. Covers chain blocks, lever blocks, electric hoists and the beam trolleys they run on. The trolley element of a girder-clamp-trolley combo is built to AS 1418.2, while the clamp portion is built to AS 4991. European-only EN 13155 stamping is not equivalent to AS 4991. AU principal-contractor sites typically reject lifting equipment that carries only an EN 13155 mark — the requirement is AS 4991 compliance backed by a current test certificate. Every clamp AIMS sells is supplied with an individual test certificate and a unique serial number. Keep the certificate with the equipment register; the serial number ties the certificate to the physical clamp during inspection. Beam trolleys — push, geared and motorised A beam trolley turns a fixed pickup point into a moving one. The trolley wheels run on the lower flange of the beam, the hoist hangs beneath, and the load travels along the length of the beam — useful in workshops where you need to lift a load off a truck and traverse it across to a workstation, or in fabrication bays where you need to move an assembly along a production line. Three types are common: Push (manual) trolleys — you push the load along the beam by hand. Suitable for lighter loads (typically up to 5t) and short traverses. The Challenger Push Beam Trolley at 500–5000kg covers most workshop applications. Cheapest option, fastest install, no maintenance beyond keeping the wheels clean. Geared trolleys — a hand chain drives the wheels through a gear set. Better control on heavier loads, easier on the operator over longer traverses. Step up from push trolley when load weight or distance justifies it. Electric trolleys — motor-driven, controlled from a pendant. Production-line applications, long traverses, high cycle rates. The Austlift Adjustable Beam Trolley in aluminium alloy and stainless steel is a height-safety-rated trolley running at 23kN — a different product class from a lifting trolley but worth knowing exists for the right application. The Beaver YC Trolley & Girder Clamp combo integrates the clamp and trolley into a single unit that can be used static (clamped to one spot) or rolling along the beam. Pair the trolley with a chain block, lever block or electric hoist sized for the load. The trolley capacity must equal or exceed the chain block capacity — a 2-tonne trolley with a 3-tonne chain block is not a 3-tonne system, it's a 2-tonne system. Lifting beam vs spreader beam vs beam clamp — the three "beams" People searching for "beam clamp" sometimes mean "lifting beam," and the two are different products. Here's the distinction: Beam clamp / girder clamp — clamps onto a structural beam to provide a lifting point. The structural beam is part of the building. The beam clamp is the temporary attachment. Lifting beam — a rated steel beam below the hoist hook, used to spread a load across multiple pickup points. The lifting beam is part of the rigging assembly, not the building. Spreader bar — similar to a lifting beam but loaded in compression rather than bending. The slings to the load run from the spreader bar's ends back up to a single hook above. Spreader bars are common for lifting wide loads where direct chain-block attachment would create excessive sling angles. If the load won't slung directly under a single beam clamp without exceeding sling angle limits, the correct fix is a lifting beam hung from the clamp on a single vertical sling. The clamp sees a vertical pull; the lifting beam handles the multiple pickup points. We don't currently stock standard off-the-shelf lifting beams — for custom spreader and lifting-beam assemblies, contact us at our beam clamp range or call (02) 9773 0122. Inspection, lock pins and pre-use checks Beam clamps live a hard life. They get dropped, dragged across concrete, left in the rain, and chucked back in the gear cage at end of shift. Pre-use inspection takes 60 seconds and catches the failures before they happen. Check What you're looking for Data plate / WLL stamp Legible WLL, AS 4991, manufacturer name, serial number. If you can't read it, the clamp is out of service until re-tagged. Jaw faces No mushrooming, no chipped corners, no visible cracks. Wear marks are normal; structural damage is not. Screw and cam (universal type) Screw turns smoothly through full travel. No bent threads, no seized pivot. Cam jaw moves freely. Shackle / lifting eye Pin secure, no elongation, no obvious deformation. Eye not opened up. Test certificate currency Test/inspection certificate within 12 months for general lifting use, 6 months for high-cycle environments. Many AU sites require quarterly inspection on hire-fleet equipment. Beam fit before load Clamp seated correctly, screw fully tightened, jaw in full contact with the flange. Visual check before applying load. Event riggers in theatrical and concert work commonly add a redundant safety wire around the beam through the clamp's lifting eye — the suspended-load community standard for over-audience rigging. It's not required by manufacturer instruction for normal industrial lifting, but it's standard practice in entertainment rigging and worth understanding if you cross between industrial and event work. AU dogging and rigging context — who can use a beam clamp Lifting work in Australia is regulated under the WHS framework and the high-risk work licensing system. A beam clamp used to lift a load is dogging work — slinging, directing and inspecting loads. The relevant high-risk work licences are: CPCCLDG3001 Dogging — required for slinging loads, directing crane operators, and using lifting attachments including beam clamps. The minimum licence for most beam clamp lifting work. CPCCLRG3001 Basic Rigging — covers more complex slinging, the use of structural lifts, and the erection of pre-cast and structural steel members. CPCCLRG3002 Intermediate Rigging and CPCCLRG3003 Advanced Rigging — progressively more complex applications. The NSW Government dogging glossary defines a dogger as "a person qualified to sling, inspect and direct loads." The licence is held by the individual, not the workplace. On a regulated site, the person attaching a beam clamp to a beam, fitting the chain block, hooking up the load and giving the lift signal must hold at minimum a current dogging licence. Owner-operators in private workshops are not exempt from the WHS framework — only the licence-holder requirement varies between jurisdictions and work types. If you're not licensed, the practical rules are: get the work done by a licensed dogger, operate within the manufacturer's instructions for non-occupational use (where applicable), or get the licence — short-course training is widely available across Australia. Where beam clamps fail — forum-validated failure modes Talk to AU dogmen and rigger forums and a small set of failure modes shows up over and over. The good news: every one of them is preventable. Failure mode Cause Prevention Clamp slips off the flange Sling angle exceeded WLL deration, side load applied to a vertical-only clamp, screw not fully tightened. Vertical lift only unless rated otherwise. Check screw tension after load is taken up. Use a lifting beam for multi-leg slings. Clamp jaw deforms / opens up under load Overloaded — clamp WLL exceeded. Often a misjudged load weight. Know the load weight before the lift. Add 25% margin on uncertain loads. WLL is not a "guideline." Catastrophic snap of unrated import clamp Cheap unstamped clamp from a non-specialist supplier. No AS 4991 mark, no serial number, no test certificate. Buy from rigging-equipment specialists. AS 4991 stamp + serial number + cert is non-negotiable for lifting use. Wrong flange thickness — clamp won't seat Flange too thick for the clamp's range, or operator shimmed a too-large clamp. Measure the flange before ordering. Never shim a beam clamp. Bull-rigging on top flange (not bottom) Operator clamps on top of the flange to "pull up" rather than below it. Not a rated configuration. Beam clamps are for the lower flange only unless the manufacturer's documentation specifically approves top-flange use. Beam clamp on a non-load-bearing beam Clamp attached to a purlin, lintel, secondary beam or non-structural feature. The beam being clamped to must be capable of carrying the lift load. Check structural drawings or ask an engineer if unsure. NSW Resources falling-object reports cite this as a recurring issue. Threaded-rod clamp used for lifting An electrical conduit-support beam clamp (cheap stamped, threaded-rod attachment) used under a chain block. Check for AS 4991 stamp and a WLL rating in tonnes before any lifting use. If unsure, the clamp does not lift. Damaged clamp returned to service Clamp dropped, jaw chipped or screw bent — used anyway because "it still works." Pre-use inspection mandatory. Damaged clamps go out of service until inspected by a competent person. Beam clamps for scaffolding leg support A specific use case worth flagging: girder clamps used to support scaffold legs from a steel beam. The rule from r/Scaffolding and AU scaffolding industry practice: clamps must be used in pairs, one facing the other, with a check 90 fitting to prevent slip. Single-clamp attachment is not approved for scaffold leg support — the load path under typical scaffold loading produces a slip mode that single clamps don't resist. Scaffolding under AS 1576 has its own load-rating, inspection and competency requirements. Beam clamp use in this context is part of the scaffold design; a scaffolder or scaffolding inspector signs off the configuration. If you're working a maintenance or fabrication site and a scaffold leg is hanging off a single beam clamp, that's a finding for the site safety officer, not a normal configuration.

Don't guess from the section nomination. Know the load weight — and add a margin for uncertainty. The clamp WLL is the maximum, not the target. Vertical lift only — unless you're using a clamp explicitly rated for off-vertical loading. One clamp = one vertical line — multi-leg slings need a lifting beam below the clamp. AS 4991 stamp + serial number + test certificate — non-negotiable. No exceptions. Pre-use inspection — data plate legible, jaw clean, screw smooth, shackle pin secure. Beam capacity confirmed — the structural beam can carry the lift load. Engineer's call if unsure. Licensed operator — dogging or rigging licence as required for the work and the jurisdiction. The five most common mistakes — every one of them avoidable: Using a beam clamp as the suspension point for a two-leg or four-leg sling without a lifting beam below. Buying an unrated import clamp because it was cheap. The AS 4991 stamp is what makes it lifting equipment. Shimming a too-large clamp onto a thinner flange with washers or steel offcuts. Using an electrical conduit-support beam clamp under a chain block. Returning a damaged or undocumented clamp to service rather than retiring it. Frequently Asked Questions What is a beam clamp used for? A beam clamp is used to create a temporary lifting point on a structural steel beam. The clamp grips the lower flange of the beam, and a chain block, lever block, electric hoist or sling assembly hangs from the clamp's shackle or lifting eye. Common uses include workshop maintenance lifts, pulling engines from vehicles, lifting machinery for transport, fabrication shop assembly, and on-site mechanical installation work. What is the difference between a beam clamp and a girder clamp? None — they're the same product. "Girder clamp" is the formal term used in the NSW Government dogging glossary and in some manufacturer catalogues. "Beam clamp" is the more common search term and the one most operators use day to day. AIMS stocks all our products under both names; either term will find what you need. Can a beam clamp be used for lifting? A lifting-rated beam clamp can — if it's stamped to AS 4991, has a current test certificate, and is being used within its WLL and flange range. Hanging or suspension beam clamps are not rated for lifting and must not be used under a chain block. Threaded-rod beam clamps for electrical conduit support are not lifting equipment and must not be used to lift a moving load. Are beam clamps and lifting beams the same thing? No. A beam clamp clamps onto a structural beam to provide a temporary lifting point. A lifting beam is a rated steel beam hung below the hoist hook, used to spread a load across multiple pickup points. They're often used together — the lifting beam hangs from the beam clamp on a single vertical sling, and the slings to the load attach to the lifting beam. Can I use a beam clamp on an H-beam or wide flange section? Yes, provided the flange width and thickness fall within the clamp's specified range. H-beams and universal columns (UC) have wider, thicker flanges than universal beams (UB) of the same depth. Measure the actual flange dimensions and check the clamp's data plate against the measurements. The Beaver YC range covers 90–320mm flange widths and handles most AU UB and UC sections. What is the WLL of a beam clamp when used at an angle? For most beam clamps, the answer is zero — they're rated for vertical lift only. The Austlift GC01 manual specifies vertical lift only; Beaver YC, Challenger and Garrick clamps in the AIMS range follow the same rule. A small number of specialist clamps (Tiger BCU, certain Crosby and Riley models) are rated for off-vertical loading at specified angles, but these are the exception. Check the data plate before assuming any side-load capacity. Do beam clamps comply with AS 4991? All lifting-rated beam clamps stocked at AIMS comply with AS 4991:2004 and are supplied with an individual test certificate and a unique serial number. AS 4991 is the primary Australian Standard for below-the-hook lifting devices including girder clamps. EN 13155 (the equivalent European standard) is not accepted as a substitute on most AU principal-contractor sites — AS 4991 stamping is what's required. Can I use one beam clamp to lift a load with a two-leg sling? No — not without a lifting beam between the clamp and the slings. Two or more sling legs from a single clamp apply a side load to the clamp jaw, which is rated for vertical loading only. The fix is a lifting beam (spreader bar) hung from the clamp on a single vertical sling. The slings to the load attach to the lifting beam, and the clamp sees only the vertical line it's rated for. What's the difference between AS 4991 and AS 1418.2? AS 4991:2004 covers the design, testing and marking of lifting devices including beam clamps, plate clamps and lifting magnets. AS 1418.2 covers serial-hoists (chain blocks, lever blocks, electric hoists) and the beam trolleys they run on. A girder-clamp-trolley combo is built to both standards — AS 4991 for the clamp portion, AS 1418.2 for the trolley. Can a hanging or suspension beam clamp be used for lifting? No. Hanging clamps are rated for static dead-loads — fixed services, lighting bars, conduit, ductwork. Their WLL assumes the load is centred and unmoving. Lifting under a chain block applies dynamic loads the clamp wasn't designed for. Always check the data plate: a lifting clamp will be marked AS 4991 with a WLL in tonnes; a hanging clamp will typically be marked with a maximum-load figure only and no AS 4991 reference. Do I need a dogging or rigging licence to use a beam clamp in Australia? For lifting work on a regulated workplace, yes — at minimum a CPCCLDG3001 Dogging licence. Slinging loads, attaching lifting equipment to structural members and directing crane or hoist operators are dogging activities under the WHS framework. More complex lifting (structural steel erection, complex multi-point lifts) requires a Basic, Intermediate or Advanced Rigging licence. Owner-operators in private workshops are not exempt from the WHS framework — only the licence-holder threshold varies. If you're not licensed, get the work done by a licensed dogger or do the short-course training. How do I inspect a beam clamp before use? Five-point check: data plate legible (WLL, AS 4991, serial number visible); jaw faces clean and undamaged (no mushrooming or cracks); screw and cam moving smoothly through full travel; shackle or lifting eye undamaged with secure pin; current test/inspection certificate. Damaged or undocumented clamps go out of service until re-tagged by a competent person. Pre-use inspection takes 60 seconds and catches the failures before they happen. What flange thickness range do beam clamps fit? Each clamp model specifies its own flange range, typically printed on the data plate. The Austlift GC01 1-tonne covers 75–220mm flange widths; the Beaver YC industrial range covers 90–320mm depending on capacity. Flange thickness ranges are similarly model-specific. The rule: measure both width and thickness before ordering, don't guess from the section nomination, and never shim a too-large clamp onto a thinner flange. Why does my beam clamp slip on the flange? Three common causes: side load from an off-vertical sling angle (vertical lift only unless rated otherwise), screw not fully tightened down before the load was taken up (re-check screw tension after initial load), or flange thickness outside the clamp's specified range. A beam clamp that's slipping under load needs to be unloaded immediately and the cause identified before continuing. Can a beam clamp be used on top of an I-beam flange (bull rigging)? Standard lifting beam clamps are designed for the lower flange only. Top-flange "bull rigging" configurations are not rated unless the manufacturer's documentation specifically approves the orientation. The forum consensus from r/Ironworker matches the standards: bottom flange unless the data plate says otherwise. If you need to pull a load up over a beam, the conventional rigging solution is a snatch block reeving the line over the beam to a separate anchor point. For the differences between BSP, NPT, UNC and BSW thread standards, see our Thread Standards Guide. Browse key steel at AIMS Industrial for application support and stock confirmation. People Also Ask — Beam Clamps Q: What is a beam clamp used for? A beam clamp is a rigging device that attaches to the bottom flange of a structural steel beam (I-beam or H-beam) to provide a suspension point for a chain block, hoist, or load. Beam clamps are used when a fixed lifting attachment is not available — for example, during temporary lifts for equipment installation, maintenance, or removal in facilities with overhead steel structures. Q: How do I know if a beam clamp fits my beam? Beam clamps are rated for a range of beam flange widths and thicknesses. Before selecting a clamp, measure the flange width (across the bottom of the beam) and the flange thickness. Both dimensions must fall within the clamp's specified range. Operating a clamp on a beam outside its specified dimensions — particularly on an undersized or oversized flange — results in incorrect load distribution and potential failure. Q: What is the Safe Working Load (WLL) of a beam clamp? The Working Load Limit (WLL) of a beam clamp is the maximum load it is rated to carry under a direct vertical pull. This WLL decreases significantly when the lift is not vertical — a side load or angled sling imposes a horizontal component of force on the clamp and reduces effective lifting capacity. Always consult the manufacturer's load rating for the specific sling angle being used. Q: What Australian standards apply to beam clamps? AS 4991 (Lifting Devices) and AS 1418.2 (Hoists and Winches) are the primary standards relevant to beam clamps and their use in Australian workplaces. AS 4991 covers the design, testing, and safe use of lifting devices in general, while AS 1418.2 addresses hoist and crane equipment. All beam clamps and lifting equipment used in Australian workplaces should be designed, tested, and maintained to comply with the applicable Australian standards. Q: What is the difference between a beam clamp, a lifting beam, and a spreader beam? These terms describe three different devices. A beam clamp attaches to an existing structural beam to create a temporary lift point. A lifting beam (or spreader beam) is an engineered structural beam that is itself suspended from a crane and used to distribute load across multiple pick points — for example, to lift a long load from two or more attachment points. They serve fundamentally different purposes and are not interchangeable.
