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 |
|---|---|
| Grade 80 Alloy Chain | Grade 43 offers lower cost and sufficient strength for securement, but Grade 80 has higher tensile strength and is better suited for dynamic or high-stress applications |
| EN 818-2 Grade 80 Short Link Chain | Grade 43 is not rated for overhead lifting and lacks the same safety margin, but it is more cost-effective for tie-down use |
| Galvanized Chain | Zinc plated Grade 43 resists corrosion better than plain steel, but galvanized chains offer longer life in harsh environments |
| Rope Tie-Downs | Chain provides higher durability and resistance to abrasion, but rope is lighter and easier to handle in some applications |
Use Guide
How To Use And Inspect Grade 43 Chain NACM
- Always verify the working load limit matches the expected load — never exceed it
- Inspect the chain before each use for signs of wear, deformation, or broken welds
- Ensure the forged clevis hooks are fully engaged and not twisted or bent
- Use only in cargo securement, towing, or logging — do not use for overhead lifting
- Keep the chain dry and clean when not in use to preserve the zinc finish
- Replace the chain if the marking is worn, the link is stretched, or the hook shows deformation
- Store on a rack or in a drum to prevent kinking and surface damage

Answers
Grade 43 Chain NACM FAQ
Is this chain suitable for overhead lifting?
No. This chain is designed for cargo securement, towing, and logging only. It is not rated for overhead lifting and should not be used in hoisting applications.
What is the design factor for this chain?
A 3:1 design factor is used, meaning the minimum breaking force is three times the stated working load limit. This meets NACM2010 standards for securement chains.
Can I get a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order upon request. It confirms the material composition and test results.
What finishes are available?
The chain is available in self-color finish or zinc plated finish. Zinc plating improves corrosion resistance for outdoor or wet environments.
How are the chains packed for export?
Chains are packed in drums on steel pallets. We can adjust the drum count and pallet pattern to suit your warehouse or shipping needs.
Can I order custom lengths?
Yes. Custom lengths and quantities can be built to your specification. Contact us with your drawing or requirements for a quote.
What is the lead time for this chain?
For standard sizes in stock, lead time is about 15 to 20 days. New production takes about 25 days plus 7 days packing, totaling around 35 days before shipment.
