AIMS Marine Capability — Why Marine Industry Trusts Us

AIMS Industrial has supplied Australian industry from our Milperra warehouse since 1988. Marine — cruise refits, shipyards, ports, offshore platforms and defence yards — sits squarely in our wheelhouse because marine work demands exactly what we're built for: breadth of range across every category a ship needs, quality brands that survive a saltwater environment, and speed when a vessel is alongside and the tide won't wait.

Think of a modern cruise liner like a floating city. Thousands of castors on service trolleys, hospitality carts and laundry equipment. Hundreds of bearings in HVAC, galley equipment, deck machinery and stabilisers. Dozens of belts, pulleys and couplings driving everything from sewage treatment to ice machines. Tonnes of cleaning chemicals, PPE for thousands of crew members, fasteners by the pallet, lubricants by the drum. The same logic applies — at different scale — to a naval frigate mid-build, an FPSO doing a turn-around, or a tugboat in for its annual.

Brands we lean on heavily for marine work: BUMAX (316 stainless A4-80 — the Swedish-made flagship marine fastener), Macnaught (marine-grade greases and lubrication systems), Loctite (marine anti-seize, retaining compounds, threadlockers), Gates (drive belts and hose), NACHI (sealed bearings for marine machinery), Bossweld (welding consumables across steel, stainless and aluminium), CRC (salt-removal cleaners and corrosion inhibitors), PFERD and Klingspor (abrasives), Sutton Tools (Australian-made drilling), Stahlwille (premium German hand tools), Mackay and Champion.

Cruise Liner Refit & Maintenance Supply — Built for the Refit Clock

Cruise liner refits are intense, compressed supply events. A typical wet-dock or alongside refit window in Australia runs 14 to 21 days, during which the ship is open from engine room to lido deck and procurement is firing requisitions every hour. Miss a delivery slot and the ship sails with the work incomplete — that's the operational reality cruise lines, refit project managers and yard procurement teams live with.

AIMS's value to cruise refits comes from three things:

1. Breadth. One supplier covering castors, bearings, fasteners, lubricants, abrasives, welding, PPE and cleaning chemicals reduces the procurement overhead of running 20 specialist accounts.
2. Speed. In-stock items typically ship within one business day from Milperra. Items we need to bring in: freight ETA confirmed when you place the order, so you can plan around it.
3. Quality. Cheap product fails twice as fast in a saltwater environment. Our brand focus is exactly what marine maintenance crews need — Loctite, Macnaught, Gates, BUMAX, NACHI, Bossweld, CRC, PFERD, Stahlwille.

What Cruise Refits Buy in Volume — Real Operational Categories

• Castors at scale — service trolleys, hospitality carts, supply trolleys, laundry equipment, food-service trolleys, housekeeping carts. Stainless steel or zinc-plated for salt-spray resistance. A single cruise liner can run thousands of castors and a refit will replace hundreds of failed or seized units. Cross-link wheels and trolleys for whole-assembly replacements.
• Bearings across the ship — HVAC fan motors, galley equipment, sewage treatment pumps, laundry equipment, deck machinery. Deep groove ball bearings, needle roller bearings, sealed industrial bearings. NACHI and Gates are our heavy-hitters here.
• Fasteners by the pallet — 316 stainless for exposed work, BUMAX A4-80 for structural, zinc-plated for internal. Stainless fasteners in M5 through M24, plus imperial for legacy systems on older vessels.
• Marine-grade greases and lubricants — saltwater-resistant greases (Macnaught marine grade), wire rope grease for crane wires, gear oil for drive systems. Macnaught, Alemlube, general greases and full lubrication range.
• PPE for crew and contractors — hard hats, safety glasses, gloves, respirators, fall arrest gear. PPE consumption on a refit is enormous because cleaning, painting, grinding and welding all happen simultaneously.
• Cleaning chemicals and degreasers — for engine room work, bilge cleaning, galley deep-clean, deck preparation before painting. CRC heavy industrial range plus WD-40 bulk for general MRO.
• Hand tools and power tools — replacement, top-up, lost-to-the-deep replacement. Stahlwille premium spanners, sockets and torque tools (Stahlwille); Sidchrome and Mackay (Mackay) volume; impact wrenches and cordless tools.

Australian cruise terminals we deliver to: Sydney Overseas Passenger Terminal at Circular Quay, White Bay Cruise Terminal, Brisbane International Cruise Terminal at Luggage Point, Fremantle Passenger Terminal, Cairns Cruise Terminal, Hobart Macquarie Wharf. Delivery to refit yards (Garden Island, Forgacs Brisbane, Henderson) by arrangement.

Naval & Defence Shipbuilding — Henderson, Osborne, Williamstown, Forgacs

Australian naval shipbuilding is in a multi-decade growth phase. Henderson Western Australia is the AUKUS submarine sustainment hub plus a major naval shipbuilding precinct. Osborne South Australia hosts ASC and BAE Systems building Hunter-class frigates and supporting AUKUS. Williamstown Victoria runs BAE's naval refit and build operations. Forgacs in Brisbane is Tier 1 defence-rated. The Henderson Defence Precinct upgrade alone is projected to generate billions in supply chain spend through 2040.

For shipyards working defence contracts, the supplier requirements are different from commercial refit. Defence work typically demands:

• Quality system documentation — ISO 9001 or equivalent, traceable material certs, batch records on critical fasteners and consumables.
• ADF Naval Standard Procedure (NSP) compliance on specific structural and welding consumables.
• AS/NZS welding consumable compliance — welding rod certified to AS/NZS 4855 for steel, AS/NZS 2576 for aluminium, AS/NZS 4854 for stainless.
• High-strength fasteners — Grade 8.8 / 10.9 / 12.9 to AS 1252 (high-strength friction-grip), AS 1110 (commercial bolts), with material certs on demand. Bolt range includes structural grades.
• Security-cleared delivery — for higher-classification yards, our delivery process can integrate with your gate procedures and visitor management.

What we supply day-to-day to defence and commercial shipyards:

• Welding consumables — stick, MIG and TIG across steel, stainless, aluminium. Bossweld is our volume marine welding brand; welders and TIG welders available.
• Abrasives at scale — cutting wheels, flap discs, grinding wheels, sanding belts. PFERD and Klingspor for high-performance / long-life duty.
• Drilling consumables — cobalt drill bits, annular cutters, hole saws. Sutton Tools Australian-made HSS-Co for stainless and high-tensile work.
• Structural fasteners — Grade 8.8 and 10.9 structural bolts, 316 stainless for exposed deck and superstructure work, BUMAX for critical applications.
• PPE at industrial scale — welding helmets (PAPR-compatible), respirators for confined space and welding fume, fall arrest.

The AUKUS programme through 2040+ means defence shipbuilding will be a multi-decade demand cycle for Australian industrial supply. AIMS is positioned to scale with it.

Port Authority & Maintenance Supply

Australian ports run continuous maintenance programmes — wharf infrastructure, container handling equipment, tug fleets, pilot boats, mooring hardware, port-side cranes and lifting equipment. Port Authority of NSW operates Sydney Harbour, Port Botany, Newcastle, Eden and Yamba. Port of Brisbane, Fremantle Ports, Port of Melbourne, Flinders Ports (Adelaide), North Queensland Bulk Ports each run substantial in-house and contracted maintenance teams.

What ports buy from AIMS:

• Lifting and rigging — wire rope, shackles (to AS 2741), lifting hooks, chain blocks, turnbuckles, complete lifting equipment. Mooring lines and mooring hardware servicing for tugs and pilot boats.
• Crane maintenance lubricants — high-tackiness chassis greases, open gear lubricants, wire rope dressings. Macnaught grease systems for centralised lube delivery on port cranes.
• Site PPE — hard hats (AS/NZS 1801), safety glasses (AS/NZS 1337), gloves, fall arrest harnesses for crane and wharf work.
• Bulk supply on maintenance contracts — scheduled deliveries against blanket purchase orders for fasteners, consumables, abrasives, cleaning chemicals.
• Welding for wharf and structural repair — coastal corrosion eats wharf structures; MIG repair on steel piles and bracing is constant work.

Coastal environments accelerate everything. Stainless that lasts 20 years inland will pit and crevice-corrode within 5 years exposed to salt aerosol. Port maintenance teams know this and procure accordingly.

Offshore Oil & Gas — FPSO, Platform & Supply Vessel MRO

Australian offshore O&G clusters across the North West Shelf (Karratha, Dampier — Woodside, Chevron operations), Darwin (Ichthys, Bayu-Undan), and the Bass Strait (ExxonMobil and offshore Otway). FPSOs (Floating Production, Storage and Offloading vessels), fixed platforms, and the supply vessel fleets servicing them all consume industrial supplies at scale and operate in some of the harshest marine environments on the planet.

Offshore work brings particular demands:

• Heavy-duty everything — offshore platforms see relentless wind, salt aerosol, UV and mechanical loading. Cheap product fails fast and replacement involves helicopter freight or supply vessel time — both expensive.
• Hose, fittings, valves for hydraulic systems on cranes, BOPs (blowout preventers) and process equipment. Hoses, hydraulic fittings, valves, ball valves, butterfly valves.
• Fall arrest and confined space PPE — offshore work involves tank entry, vessel internals, high steel. AS 2865 (confined space) and AS/NZS 1891 (industrial fall arrest) compliance is mandatory.
• Long lead times — supply chains route through Karratha, Darwin or Bass Strait ports. We mobilise via your nominated freight forwarder or direct to port for vessel loading.

Stainless Steel for Marine Environments — 316, 904L & Duplex

The marine fastener and structural stainless conversation has more depth than most catalogues let on. 316 (and its high-purity variant 316L) is the default marine stainless — it's the right answer for the great majority of marine fastening jobs. But 316 isn't bulletproof, and getting the grade right matters when corrosion failure means rework, leaks or worse.

316 Stainless — The Marine Default

316 contains ~2-3% molybdenum, which dramatically improves resistance to chloride pitting compared to 304. For marine fasteners exposed to salt aerosol and intermittent salt spray, 316 is the standard. BUMAX 316 A4-80 (the property-class 80 designation under ISO 3506-1) is our flagship marine fastener line — Swedish-made, full traceability, the gold-standard 316 marine bolt.

Use 316 stainless for:

• Above-waterline exposed structural fastening
• Deck hardware and superstructure
• Galley, accommodation, and laundry equipment
• HVAC systems and ductwork supports
• General marine MRO where stainless is specified

904L & Duplex 2205 / Super Duplex 2507 — When 316 Isn't Enough

High-chloride or warm-seawater environments can pit and crevice-corrode even 316 within years. The step-ups:

• 904L — a high-alloy austenitic stainless (~6% molybdenum) with strong resistance to chlorides and sulfuric acid. Used for chemical processing on tankers, scrubber systems, and exhaust components handling acidic condensate.
• Duplex 2205 — austenitic-ferritic dual structure, roughly twice the yield strength of 316 and dramatically better stress-corrosion cracking resistance. Common in offshore structural and high-load marine applications.
• Super Duplex 2507 — even higher chromium and molybdenum. Used in warm seawater (tropical offshore, desalination plants) and severely chloride-laden environments where 2205 isn't enough.

904L and duplex fasteners are specialty items — we source them on request rather than holding stock. Ring us with the spec and we'll quote against your delivery window.

Cathodic Protection — Sacrificial Anode Selection

Cathodic protection on marine hulls and immersed equipment uses sacrificial anodes that corrode preferentially to protect the parent metal. Anode material depends on water salinity:

• Zinc anodes — for saltwater (open ocean). The traditional choice. Inactive in fresh or brackish water.
• Aluminium anodes — increasingly the default for saltwater, especially under MARPOL and environmental scrutiny over zinc dissolution. Works in saltwater and high-salinity brackish.
• Magnesium anodes — for fresh water and low-salinity (river, estuarine). Far too reactive for saltwater (consumes itself within months).

Using zinc in fresh water = no protection. Using magnesium in saltwater = anode disappears in weeks. Sacrificial anodes are a specialty item we source on request — ring with the application and we'll quote.

Marine Lubricants, Greases & Anti-Seize

Saltwater is brutally hostile to standard industrial lubricants. The wrong grease will wash out within days; the right one lasts a refit cycle. Across Macnaught, Alemlube, Loctite, CRC and the broader lubrication range, AIMS holds the marine-specific grades.

Greases for Marine Service

• Calcium sulfonate marine greases — exceptional water resistance (won't wash out under direct salt-water immersion), excellent mechanical stability, broad temperature range. The right grease for boat trailer bearings, immersed pivots, wire rope dressing.
• Aluminium complex marine greases — water-resistant, high dropping point, good for HVAC fan bearings and high-temperature deck applications.
• Lithium complex — better than standard lithium but still gets washed out under sustained water exposure. OK for protected pivots and indoor marine MRO.
• Wire rope grease (specialty) — for crane wire ropes on port and offshore equipment. Penetrating, water-displacing, with corrosion inhibitors.

Anti-Seize for Stainless-on-Stainless Underwater

Stainless fasteners going into stainless or aluminium underwater fittings need anti-seize, full stop. The problem: standard copper-based anti-seize is wrong for two reasons in marine — copper contributes to galvanic mismatch on aluminium, and standard formulations break down in seawater.

Loctite 8023 Marine Grade Anti-Seize is the right specification for stainless fasteners in seawater immersion or splash zones — formulated without copper, with corrosion inhibitors specific to saltwater. Standard Loctite retaining compounds and threadlockers also have marine-grade variants for fastener locking in vibrating environments (deck machinery, engine room mounts).

For deeper reference: Anti-Seize Compound Guide, Industrial Lubricants Guide, Oil Viscosity Chart, Gear Oil Guide.

Marine Sealants, Gaskets & Bonding

Marine sealants and adhesives are a category where product choice has to be exactly right. Underwater bond failure isn't an inconvenience — it's a leak path or a structural failure.

Sika Marine vs Sika Construction — They Are Not Interchangeable

One of the most common product confusions in marine work: Sika manufactures both marine-grade (Sika Marine) and construction sealants under similar-looking labels. They are formulated for completely different chemistries and substrates and they do not cross over.

• Sika 291 — the standard marine adhesive sealant for deck hardware bedding, hull-to-deck joints, sealing through-hull fittings.
• Sika 292 — high-strength structural marine adhesive for stronger bond applications.
• Sika 290 DC — deck caulking specifically for teak deck seam sealing.
• Sika 296 — clear marine glazing sealant for portlights and windows.

Sika Marine grades are specialty items we source on request — ring with the product code and application and we'll quote against your delivery window. For general industrial sealing on board (machinery flanges, ventilation, non-immersion), our sealants and adhesives and sealants range covers the standard requirements.

Gaskets for Marine Flanges

Pump, valve and pipework flanges throughout a ship's engine room and process systems use the same gasket types as land-based industrial. For high-pressure / high-temperature steam, exhaust and process flanges, spiral wound gaskets are the standard — refer to our Spiral Wound Gasket Guide for the AS 4087/2129 and ASME B16.5 flange standard work. Our general gaskets range covers PTFE, graphite, fibre and rubber sheet gaskets for the bulk of low-pressure marine sealing.

Dowty Washers for Hydraulic Fittings

Marine hydraulic systems (crane circuits, steering rams, deck machinery) use BSP and JIC fittings sealed with bonded seal washers — Dowty washers. See our Dowty Washer Guide for sizing and pressure ratings.

Welding for Marine Hulls, Structures & Repair

Marine welding spans three substrate families that each need specific consumable selection. Get the filler wrong and your weld cracks within months in service.

Aluminium Welding — Marine 5XXX Series Hulls

Aluminium boat and ship hulls use 5XXX series marine-grade alloys — specifically 5083 (high-strength, used for hull plating on commercial and military vessels), 5086 (slightly lower strength, easier to form), and 5052 (lighter applications). These alloys can only be reliably welded with matching filler:

• 5083 plating → use 5183 filler (or 5356 for less critical work)
• 5086 plating → use 5356 filler (or 5183 for higher strength)
• 5052 plating → use 5356 filler (standard match)

Using 4043 silicon filler on 5083 — a common mistake from welders coming off automotive — produces a weld that cracks within months in salt-water service. The magnesium in 5083 requires a magnesium-matched filler. AS/NZS 2576 covers aluminium filler classifications. Bossweld stocks the marine aluminium fillers; ring us with the substrate and we'll spec the right wire.

Stainless Welding for Marine Service

For stainless welding on marine equipment (sanitary, ballast, cargo holds), use:

• 316L parent → 316L filler (matches molybdenum content for chloride resistance)
• 304L parent → 308L filler (standard austenitic match)
• Duplex 2205 → 2209 filler (matches duplex chemistry)

Using 308L on a 316L base for marine work strips out the molybdenum and produces a weld that pits before the parent metal. AS/NZS 4854 covers stainless filler classifications.

Steel Welding for Ship Structure & Repair

For mild steel hull and structural repair, AS/NZS 4855 covers the consumable classifications. Bossweld covers MIG wire (ER70S-6 standard), stick electrodes (E7016 / E7018 low-hydrogen for structural), and TIG rod. MIG welders and TIG welders available; refer to our MIG Welding Guide and Welding Helmet Guide for setup detail.

Castors, Material Handling & Hospitality Equipment

This category is bigger for marine industry than most categories realise. Castors alone — service trolleys, hospitality carts, supply trolleys, laundry equipment, food-service trolleys, deck trolleys — run into the thousands on a single cruise liner. The same applies at smaller scale on ferries, naval vessels (mess trolleys, equipment carts) and offshore platforms (galley and accommodation carts).

Marine castor specification:

• Stainless steel housing — for direct salt-spray exposure or external use. The mid-priced choice that delivers the longest life.
• Zinc-plated steel housing — for protected internal use (accommodation, galleys, laundries). Cheaper, works well where salt-spray isn't direct.
• Polymer / nylon housing — for specific corrosive-environment applications.
• Wheel material — polyurethane for smooth deck surfaces and low noise, rubber for grip on wet surfaces, nylon for heavier loads.
• Bearing — sealed precision bearings outlast pressed-steel cup-and-cone by 5–10× under marine exposure.

For complete trolley assemblies and material handling: trolleys, wheels, lifting equipment. We can quote bulk orders and pre-staged refit deliveries.

Bearings, Power Transmission & Drive Components for Marine Machinery

Marine machinery — HVAC, refrigeration, pumps, deck winches, stabilisers, sewage treatment, laundry equipment, ice machines — runs on bearings, belts, chains, pulleys and couplings, all in environments where moisture, salt and temperature swing all conspire against drive components.

Our marine drive-train coverage:

• Bearings (492 SKUs) — including sealed and shielded for marine moisture exposure. Deep groove ball bearings (6200, 6300 series) for HVAC fan motors and general pumps; needle roller bearings for compact / high-load drive ends.
• NACHI & supporting brands — NACHI (Japanese-made precision bearings) is our marine-environment hero. Sealed (-2RS) variants for moisture-protected service.
• Drive belts — Gates V-belts, timing belts, micro-V for marine fan drives, generator-set drives, pump drives. Heat-and-oil-resistant variants for engine-room duty.
• Pulleys and taper-lock bushings for belt-drive servicing. See Pulley Types Guide and Taper Lock Bush Guide.
• Flexible couplings and sprockets for pump and motor drives, plus roller chain for conveyors and lifting equipment.
• Marine bearing maintenance — refer to Bearing Maintenance Guide, Bearing Puller Guide, Deep Groove Ball Bearing Guide, Thrust Bearing Guide, Needle Roller Bearing Guide.

Tools, PPE & Site Equipment for Marine Workers

Marine work — refit, shipyard, offshore, port — runs identical PPE requirements to any other high-hazard industrial environment, layered with marine-specific exposures (confined spaces, working at height on hulls, welding fume in tight compartments, fall hazard from open decks).

Standards reference and AIMS coverage:

• AS/NZS 1801 (Hard hats) — hard hats for all shipyard, port and offshore work.
• AS/NZS 1337.1 (Eye protection) — safety glasses rated medium-impact for grinding/cutting work, plus tinted for welding flash. Cross-link Safety Glasses Guide.
• AS/NZS 1716 + AS/NZS 1715 (Respiratory) — respirators for welding fume, paint spraying, abrasive dust. Refer to our Respirator Guide.
• AS 2865 (Confined Space) — critical standard for tank entry on ships. Atmospheric monitoring, harnesses, rescue plan all required.
• AS/NZS 1891 (Fall arrest) — height safety for working at height on hulls, masts, gantries, offshore structures.
• AS/NZS 2210 (Safety footwear) — refer to our Safety Boots Guide.
• High-visibility workwear — refer to our Hi-Vis Vest Guide.
• Lockout / tagout — LOTO for engine room and electrical isolation during maintenance.

Hand tools and power tools: Stahlwille (premium German), Champion (volume), Mackay, full hand tool range, power tools, sockets, measuring tools, impact wrenches.

Maritime Regulatory Context — Australian & International

Marine industrial supply works inside a stacked regulatory framework — Australian domestic regulators on top of international IMO conventions on top of classification society rules. Quick orientation:

Australian Maritime Regulators

• AMSA (Australian Maritime Safety Authority) — the federal regulator. Issues and enforces Marine Orders covering everything from seafarer certification (Marine Orders Part 3) to ship construction (Part 32) to safety equipment (Part 25) to environmental compliance (Part 91-97). AMSA inspections (Port State Control for foreign-flag, Flag State for Australian-flag) verify compliance — and in 2026 AMSA is running a minimum of 2,400 PSC inspections with intensified focus on planned maintenance systems and ISM Code compliance.
• Navigation Act 2012 (Cth) — the primary federal Australian shipping legislation.
• State maritime regulators — Transport for NSW (RMS), Maritime Safety Queensland, Marine Safety Victoria, Department of Transport WA, etc. — handle state-registered domestic commercial vessels.

International Conventions

• SOLAS (Safety of Life at Sea) — IMO convention covering ship construction, fire protection, life-saving appliances, navigation safety. The cornerstone of international maritime safety law.
• MARPOL (Marine Pollution) — IMO convention covering pollution prevention. Annex I (oil), Annex II (chemicals), Annex IV (sewage), Annex V (garbage), Annex VI (air pollution including ECA / sulphur emissions).
• STCW (Standards of Training, Certification and Watchkeeping) — IMO convention setting seafarer qualifications.
• ISM Code (International Safety Management) — mandates Safety Management Systems on board, with planned maintenance regimes being one of AMSA's primary inspection focus areas through 2026.

Classification Societies

Class societies set the rules for ship construction, materials and survey. Active in Australian waters:

• Lloyd's Register (LR) — UK, oldest of the majors
• DNV — Norwegian, major class society for offshore and shipping
• ABS (American Bureau of Shipping) — US
• Bureau Veritas (BV) — French
• ClassNK (Nippon Kaiji Kyokai) — Japanese

Class-approved consumables (welding electrodes, structural steel, fasteners) carry the class society stamp on the certificate. For class work, ring us with the spec and class society requirement and we'll source consumables with the right certification.

Defence Naval Standards

Royal Australian Navy and Australian Defence Force work runs to ADF Naval Standard Procedures (NSP) plus civilian standards where called up. Henderson, Osborne, Williamstown shipyards working AUKUS submarine programmes, Hunter class frigates, Offshore Patrol Vessels and continuous naval sustainment require Tier 1 supplier qualification.

Marine Industrial Supplies — FAQs

What does AIMS supply to marine industry in Australia?

AIMS supplies the full industrial breadth that marine industry needs day-to-day: 316 stainless and BUMAX A4-80 fasteners, saltwater-grade greases and lubricants (Macnaught, Alemlube, CRC), bearings (NACHI, deep groove, needle roller), drive belts and pulleys (Gates), castors and trolleys at scale, welding consumables across steel/stainless/aluminium (Bossweld), abrasives (PFERD, Klingspor), hand and power tools (Stahlwille, Champion, Mackay), pumps, valves, hoses, hydraulic fittings, PPE, cleaning chemicals and Loctite 8023 marine anti-seize. We cover cruise refit MRO, shipyard new-build and repair, port maintenance, offshore O&G platforms, defence shipbuilding, ferry operators and marine engineering shops.

Do you supply cruise liner refit projects in Australia?

Yes — cruise refit is one of our strongest marine fits. The breadth of categories we cover means a single AIMS account can replace multiple specialist accounts, our in-stock items typically ship within one business day from Milperra, and our brand focus (Loctite, Macnaught, Gates, BUMAX, NACHI, Bossweld) is exactly what marine maintenance crews need. We deliver to Sydney OPT and White Bay, Brisbane, Fremantle, Cairns and Hobart cruise terminals, and to refit yards (Garden Island, Forgacs Brisbane) by arrangement. For refit windows, we pre-position stock and run scheduled deliveries.

Do you supply Tier 1 defence shipyards (Henderson, Osborne, Williamstown)?

Yes — we step into Tier 1 yard supply chains where required. We can provide material certs on critical fasteners and consumables, support quality system documentation, and meet AS/NZS welding consumable standards (AS/NZS 4855 steel, AS/NZS 4854 stainless, AS/NZS 2576 aluminium). For ADF Naval Standard Procedure (NSP) requirements on specific consumables, ring us with the spec. The AUKUS programme and Hunter-class frigate build through 2040+ make defence shipbuilding a multi-decade supply opportunity and AIMS is positioned to scale with it.

What stainless steel grade should I use for seawater exposure?

316 (or 316L) is the marine default and the right answer for most marine fastening — exposed deck work, superstructure, accommodation, HVAC, general MRO. BUMAX 316 A4-80 is our flagship marine fastener line. Above-waterline and intermittent salt-spray applications, 316 is fine. For high-chloride, warm-seawater or crevice-prone applications, step up to 904L (high-molybdenum austenitic) or duplex 2205 / super duplex 2507. If you're seeing 316 fasteners pit and fail within months, the problem is the grade is wrong for the environment — not the supplier.

When do I need 904L or duplex stainless instead of 316?

Three indicators: (1) warm seawater exposure (tropical offshore, North West Shelf, desalination plants); (2) crevice geometry with sustained chloride exposure (gasket faces, threaded joints under wetting); (3) high-strength requirement combined with marine corrosion (offshore structural, drive shafts, pump impellers). Duplex 2205 has roughly twice the yield strength of 316 plus far better stress-corrosion cracking resistance. 904L excels for chemical processing on tankers and scrubber systems. These are specialty items — we source on request.

What's BUMAX 316 A4-80 and why is it the marine fastener flagship?

BUMAX is a premium Swedish-made stainless fastener brand. The "316" is the steel grade (austenitic, ~2-3% molybdenum, the marine-standard chloride-resistant stainless). The "A4-80" is the ISO 3506-1 classification — A4 means molybdenum-containing austenitic stainless (the 316/316L family) and 80 is the property class (800 MPa minimum tensile strength). That combination — proper marine-grade stainless chemistry plus high property class — makes BUMAX A4-80 the gold-standard marine bolt for critical structural fastening where both corrosion resistance and load capacity matter. Full traceability and certification supplied. Browse BUMAX.

What grease should I use on boat trailer bearings or marine pivots exposed to salt water?

Calcium sulfonate marine grease or aluminium complex marine grease — not standard lithium. Lithium grease washes out under direct or repeated salt-water immersion within days. Calcium sulfonate is the standout for water resistance: it physically refuses to emulsify with water and stays in place under salt-water exposure. Aluminium complex is a close second with strong high-temperature performance. Macnaught marine grades and our broader greases range cover the specifications. For pivots that get repeated salt-water dunking (boat trailers, immersed deck machinery), calcium sulfonate is the right call.

What's the difference between Sika Marine and Sika construction sealants?

They are different products formulated for different chemistries and substrates. Sika Marine (Sika 291, 292, 290 DC, 296) is engineered for marine substrates — fibreglass, marine plywood, teak deck timbers, marine aluminium — under saltwater exposure. Sika construction grades (Sikaflex 11FC, 221, etc.) are for building substrates and don't survive marine immersion. Using construction Sikaflex where marine Sika 291 is specified is a common and expensive mistake — bonds fail within weeks underwater. If you're not sure which grade you need, ring us with the application (deck hardware bedding, through-hull, teak seam sealing, portlight glazing) and we'll source the right grade.

Why does aluminium-to-stainless galvanic corrosion happen so fast on marine builds?

Saltwater is an outstanding electrolyte. Put two dissimilar metals in electrical contact in saltwater and you've built a battery — the more anodic metal (aluminium) corrodes preferentially to protect the more cathodic metal (stainless). On an aluminium hull with uninsulated stainless fasteners, the aluminium becomes the sacrificial anode and dissolves around the fastener within 12 months, often faster in warm water. Standard practice: nylon insulating bushes through bolt holes, isolation pads between dissimilar metals, marine-grade bedding compound to break electrical contact. This trap is documented heavily across r/Boatbuilding and r/MarineEngineering operational threads.

What anti-seize should I use on stainless fasteners exposed to seawater?

Loctite 8023 Marine Grade Anti-Seize. Standard copper-based anti-seize is wrong for marine because (1) copper contributes to galvanic mismatch on aluminium substrates, and (2) standard formulations break down in saltwater. Loctite 8023 is formulated without copper and with corrosion inhibitors specific to saltwater — it's the right specification for stainless fasteners in seawater immersion or salt-spray zones. Without anti-seize, stainless-on-stainless threading underwater galls and seizes regularly because biofilm plus chloride accelerates the galling chemistry.

Can AIMS supply castors at cruise refit scale (hundreds per order)?

Yes — castors at scale is one of our marine industry strengths. We hold 178+ castor SKUs across stainless steel housings (the longest service life under salt-spray), zinc-plated steel (cost-effective for protected internal use) and polymer housings. For cruise refit windows, we'll pre-position bulk stock based on your forecast and run scheduled deliveries. Ring us with the application (service trolleys, hospitality carts, laundry, deck) and quantity and we'll quote.

Do you deliver to Australian shipyards, cruise terminals and offshore mobilisations?

Yes — national delivery to shipyards, cruise terminals, port maintenance depots, naval bases (by arrangement) and offshore mobilisation points. In-stock items typically ship within one business day from our Milperra warehouse. Specific destinations we deliver to regularly: Sydney OPT and White Bay cruise terminals, Garden Island, Henderson WA (defence and commercial), Osborne SA (ASC, BAE), Williamstown VIC, Forgacs Brisbane, Cairns and Townsville commercial yards, Newcastle, plus port maintenance for Port Authority NSW, Port of Brisbane, Fremantle Ports, Port of Melbourne. Offshore mobilisations through Karratha, Dampier and Darwin by arrangement.

What welding filler do I use for marine aluminium 5083 hull plate?

5183 filler is the matched-strength choice for 5083 plate (or 5356 filler for less critical structural welds). 5083 is a magnesium-alloyed aluminium and requires a magnesium-matched filler — using 4043 silicon filler on 5083 (a common mistake from welders coming off automotive work) produces a weld that cracks within months in salt-water service. For 5086 plate use 5356 filler. AS/NZS 2576 covers aluminium filler classifications. Bossweld stocks marine aluminium fillers; ring us with the substrate and we'll spec the right wire.

What does AMSA regulate and how does it affect ship maintenance supply?

AMSA (Australian Maritime Safety Authority) is the federal maritime regulator. It issues and enforces Marine Orders covering ship construction, safety equipment, seafarer certification, environmental compliance and operational safety. AMSA runs Port State Control inspections on foreign-flag ships in Australian ports and Flag State inspections on Australian-flag vessels. In 2026 AMSA is conducting a minimum of 2,400 PSC inspections with intensified focus on ISM Code (International Safety Management) planned maintenance system compliance. For ship operators and refit yards, that translates to documented, traceable maintenance regimes — including verified parts and consumable provenance. Our role: timely supply with documentation when required.

Can AIMS open a trade account for a shipyard or marine engineering business?

Yes — we offer trade accounts with automatic credit terms for established Australian businesses, volume pricing on bulk orders, scheduled delivery for refit windows and shutdown programmes, and Tier 1 yard supplier qualification where required. Apply via Customer Account Application or ring (02) 9773 0122 to discuss your supply chain requirements.

Can AIMS source a specific marine product not on the website?

Yes. Our standing offer for marine work: if you can't find it on the site, ring us. We have established trade relationships across the Australian industrial supply chain including specialist marine suppliers and we can typically source within the same delivery window as our in-stock range. Common requests we handle: specific Sika Marine grades (291, 292, 290 DC, 296), sacrificial anodes (zinc / aluminium / magnesium for different water salinities), 904L and duplex 2205/2507 stainless fasteners for chloride-extreme environments, marine paints and antifouling, specialist navigation hardware, marine-grade electrical fittings. (02) 9773 0122 or sales@aimsindustrial.com.au.

What's an AUKUS-compliant supplier and is AIMS positioned for the AUKUS supply chain?

AUKUS-compliant supply refers to suppliers qualified to support the AUKUS submarine programme — multi-decade build and sustainment work at Henderson WA and Osborne SA. Compliance involves ISO 9001 (or equivalent) quality systems, ITAR / DTC considerations for technology transfer, security clearance for staff handling controlled information, and Australian Industry Capability (AIC) participation. For industrial supply (fasteners, consumables, abrasives, PPE) the bar is more accessible — ISO 9001-aligned quality, documented material certs, and reliable delivery. AIMS supplies industrial consumables into defence shipyard supply chains and we can step up where Tier 1 supplier qualification is required. Ring (02) 9773 0122 to discuss.

Do you supply Sika Marine products?

Sika Marine grades are specialty items we source on request rather than holding stock. Ring (02) 9773 0122 or email sales@aimsindustrial.com.au with the specific product code (Sika 291, 292, 290 DC, 296) and the application and we'll quote against your delivery window. For general industrial sealing on board (machinery flanges, ventilation, non-immersion applications) our sealants and adhesives, sealants and tapes range covers most requirements without needing to wait on specialty marine sourcing.
