At SMEOCEAN, we supply the G70 Transport Binder Chain for cargo securement in both land transport and marine environments – including flatbed trailers, deck cargo, and container lashing. Grade 70 chain offers a working load limit approximately 20% higher than Grade 43 (High Test) chain, making it the strongest carbon steel transport chain available for load securement applications.
G70 chain is also referred to as Transport Chain, System 7, or Spectrum 7. G70 chain is NOT approved for overhead lifting.

Frequently Asked Questions (FAQ)
1. What is the difference between G70 and G43 transport chain?
G70 chain has a working load limit approximately 20% higher than Grade 43 (High Test) chain of the same size. G70 is heat-treated alloy steel, while G43 is carbon steel. For heavy-duty flatbed securement, G70 is the preferred grade.
2. Is G70 chain approved for overhead lifting?
No. G70 chain is designed for load securement and binding only. It is NOT approved for overhead lifting. For lifting applications, use G80 or G100 chain.
3. What does the gold chromate finish mean?
The gold (yellow zinc chromate) finish serves two purposes: it provides corrosion resistance, and it serves as a visual identification for Grade 70 chain, making it easy for inspectors to confirm the grade.
4. What is the working load limit for 3/8" G70 chain?
A standard 3/8" G70 binder chain has a WLL of 6,600 lbs (2,994 kg) and a minimum breaking load of 26,400 lbs.
5. What certifications does this chain meet?
All SMEOCEAN G70 transport binder chains meet NACM 2020, DOT (FMCSA CFR49 Section 393.104), and CVSA/CCMTA requirements.
6. Can I get custom lengths?
Yes, SMEOCEAN offers custom cut lengths from 6 ft to 50 ft. Contact us for a quote.
