Round Ring Selection — Quick Reference
Round rings (welded lifting rings / master rings) — STEEL rigging rings used as connection points between slings, chains + hooks. Rated to working load limit (WLL) or, for tie-down rings, lashing capacity (LC). NOT rubber sealing components — see oil seals + O-rings for those.
| Round Ring Type | Best For |
|---|---|
| Welded Round Ring (316 Stainless) — Inox World | Marine + chemical + general rigging — closed welded ring, even load distribution |
| Stainless Round Ring G316 — Austlift | Specialty lifting/rigging tasks, rated WLL/SWL |
| Tie-Down Round Ring — Austlift | Vehicle/trailer load restraint — AS/NZS 4380 rated, traceable LC marking |
Critical: Match ring WLL (or LC for tie-down rings) to the actual load — for multi-leg slings, the master ring must carry the combined angle-adjusted load, not just the straight-down weight. Lifting rings must comply with AS 3776 + AS 2550; tie-down rings with AS/NZS 4380. Damaged or deformed rings — removed from service immediately. Companion: lifting shackles, rigging + lifting slings, chain slings, plate clamps.
Round Rings (Welded Lifting Rings) for Australian Rigging
Round rings (also called welded lifting rings or master rings) are the load-rated steel rings used in rigging assemblies as connection points between slings, chains, and lifting hooks. The continuous closed loop provides a clean attachment point that handles load from any direction — essential for multi-leg sling assemblies and complex lifts. AIMS Industrial supplies round rings rated to AS 3776 and the relevant lifting standards for Australian rigging and lifting work.
The ring types we stock
- Welded round ring (Inox World, 316 stainless) — formed from steel bar with a welded join, rated for marine, chemical and general rigging use, M3–M10 bar sizes with 20–75mm ring diameters
- Stainless lifting ring (Austlift, G316) — for specialty lifting and rigging tasks, rated WLL/SWL, compatible with the wider Austlift lifting range
- Tie-down ring (Austlift) — AS/NZS 4380 rated with traceable LC marking, for vehicle and trailer load restraint

Where round rings earn their place
- Multi-leg sling assemblies — connecting 2, 3, or 4 sling legs at the master ring
- Chain sling termination — fitted as the master link at the top of chain sling assemblies
- Hook attachment points — the welded ring provides a clean, even-load attachment point for direct hook or shackle connection
- Custom rigging assemblies — connection points in fabricated lifting equipment
Sizing and load ratings
Round rings are sized by ring inside diameter, ring stock diameter (the steel bar diameter), and working load limit (WLL). AIMS's welded 316 stainless range runs from M3 bar / 20mm ring diameter up to M10 bar / 50mm ring diameter, with the Austlift lifting ring and tie-down ring rated separately to their own WLL/LC. The WLL (or LC) must match or exceed the heaviest load the ring will carry; for multi-leg slings, the master ring WLL must accommodate the combined load with appropriate angle factor.
Compliance — AS 3776 and lifting standards
Round rings used in lifting applications must comply with AS 3776 (lifting components) and the broader AS 2550 lifting safety standards. Rings must be supplied with traceable manufacturer documentation, marked with the WLL and identification number, and inspected at intervals specified by the workplace lifting safety management system. Damaged or deformed rings must be removed from service immediately.

People Also Ask — Round Rings
Q: What's the difference between the Inox World welded ring and the Austlift stainless lifting ring AIMS stocks?
The Inox World ring is a closed, welded 316 stainless ring sized by bar and ring diameter (M3–M10 bar, 20–75mm ring) for general marine, chemical and rigging use. The Austlift G316 ring is built and rated specifically for lifting and rigging tasks, with a documented WLL/SWL and compatibility with the wider Austlift lifting and fall-protection range — pick it where you need a certified lifting-rated ring rather than a general-purpose rigging ring.
Q: Why does a multi-leg sling's angle affect how much load the master ring at the top actually carries?
Each leg in a multi-leg assembly carries a share of the total suspended weight, and that share increases as the legs are angled further from vertical — a wider angle increases the tension in each leg for the same load. The master ring at the top has to carry the combined, angle-adjusted tension from every leg, not just the straight-down weight of the load. Match the master ring's WLL to that combined, angle-adjusted figure rather than the nominal capacity of the individual sling legs.
Q: What's the difference between the Austlift lifting ring and the Austlift tie-down ring?
The lifting ring is rated to a working load limit (WLL) for rigging and lifting applications. The tie-down ring is a different product, built to AS/NZS 4380 with a rated Lashing Capacity (LC) and end fittings that match common vehicle anchor points (S-hook, J-hook, flat hook, eye ring) — it's for securing loads to trailers, trucks and pallets, not for overhead lifting.
Q: What must a round ring be marked with to comply with AS 3776?
A round ring used in a lifting application must comply with AS 3776 and the broader AS 2550 lifting safety standards, and be supplied with traceable manufacturer documentation. It must be marked with its working load limit and an identification number so it can be traced back to that documentation. Rings without this marking and paperwork aren't compliant for lifting use, regardless of how they appear.
Q: When should a round ring be removed from service?
A round ring must be inspected at the intervals set by the workplace's lifting safety management system, and any ring that's damaged or deformed — bent out of shape, gouged, or showing wear at the load-bearing points — must be removed from service immediately rather than kept in use pending a formal inspection. Because a ring's rated WLL assumes an undamaged, correctly shaped ring, visible deformation is reason enough to withdraw it without waiting for the next scheduled check.
