D-Rings

D-Rings

D-rings are load-bearing rigging and lifting hardware used to provide an attachment point for chain, wire rope, webbing slings and load restraint straps on equipment, structures and vehicles. AIMS Industrial stocks D-rings in galvanised steel and stainless steel, in welded and bolt-on configurations, with rated working load limits (WLL) for lifting and load restraint applications.

Lifting vs Load Restraint Applications

D-rings used in overhead lifting must be rated and marked with a safe working load and be fit for the specific lifting purpose — they must never be loaded beyond their rated WLL and must be inspected regularly for wear, deformation and corrosion. D-rings used in vehicle load restraint (tie-down D-rings welded or bolted to trailer decks and truck bodies) must comply with the load restraint guidelines applicable to the vehicle and load. The two applications have different regulatory requirements and different D-ring specifications.

Welded vs Bolt-On D-Rings

Welded D-rings are fabricated as a welded assembly and are typically used in structural, vehicle and equipment applications where a permanent, high-strength attachment point is required. Bolt-on (plate) D-rings are bolted to a flat surface — trailer decks, container floors, workshop floors and walls — and are removable or replaceable if damaged without structural modification. Plate D-rings for load restraint typically include a rated tie-down capacity stamped on the plate.

Material Selection

Galvanised steel D-rings suit most outdoor and industrial applications at lower cost. Stainless steel (316 grade) is specified for marine, food processing and coastal applications where corrosion resistance is required for the rated service life.
