D-Rings
Weld-on Lifting Point Grade 80 Alloy Steel Forged D-Ring with Piovting Link
A heavy-duty forged alloy steel D-ring with a pivoting link designed for permanent welding to equipment or structures. It provides a secure, fixed lifting point for slings, chains, or hooks in industrial, construction, and marine environments. The 360-degree rotating link allows alignment with the load path, reducing side loading and improving lifting efficiency. Available from 1.12T to 20T safe working load, with dimensions and weight provided for each size. The D-ring is painted for corrosion resistance and suppl

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Screw pin D-ring | The weld-on version is permanently fixed and does not risk pin loss during lifting, but it cannot be removed or reused |
| Swivel eye bolt | The pivoting link offers more rotation freedom and better load alignment, but the eye bolt is easier to install without welding |
| Rigid welded lifting lug | The pivoting link reduces side loading and cable twist, but the rigid lug has no moving parts to fail |
| Temporary lifting hook | The weld-on D-ring is fixed and secure, but a temporary hook can be moved or removed after use |
Use Guide
How To Use And Inspect Weld on Lifting Point China Supplier
- Verify the welded joint is complete and free of cracks before lifting
- Ensure the pivoting link rotates freely and is not seized by debris or paint
- Match the stamped working load limit to the calculated load, not the equipment rating
- Avoid side loading by aligning the lifting sling with the D-ring centerline
- Inspect the weld and D-ring for deformation or damage after each use
- Retire the lifting point if the D-ring shows bending, the pivot seizes, or the marking is unreadable

Answers
Weld on Lifting Point China Supplier FAQ
Can this be welded to any steel thickness?
Yes, but the weld must be designed to the base material thickness and meet standard welding procedures. A qualified welder should perform the joint.
Is the pivoting link safe under dynamic loads?
Yes, when properly welded and used within the rated working load. The link is designed to rotate under load without binding.
What safety factor does this lifting point carry?
A standard 4:1 design factor, so the minimum breaking load is four times the safe working load stamped on the D-ring.
What certificates come with the order?
A Material Test Certificate to EN 10204 3.1 is supplied on request. Every batch is proof load tested with dimensional and breaking strength checks recorded.
Can you custom stamp a different tonnage or add our brand?
Yes. Custom tonnage stamping, private label marking, and OEM packing are standard options. Finishes can be zinc plated or powder coated on request.
How are they packed for export?
Cartons on pallets as standard. We can configure the carton count and pallet pattern to suit your warehouse or retail pack. Goods can be held in our Qingdao warehouse free for two months while you consolidate a container.
