The H-Lift Grade 70 Transport Chain is a high-strength, heat-treated carbon steel chain manufactured to ASTM A413/A413M-21 standards, designed specifically for heavy-duty load securement and tie-down applications.
The Grade 70 Transport Chain is the industry standard for heavy-duty load binding. Forged from heat-treated carbon steel, it provides exceptional wear resistance and a high strength-to-weight ratio. Engineered specifically for tying down heavy cargo on flatbed trailers, logging, and towing, it ensures DOT regulatory compliance for commercial transport.
Manufactured to meet the rigorous requirements of ASTM A413/A413M-21 and AS/NZS 4344, ensuring safe and legal operation for commercial haulers across multiple regions.
Forged from heat-treated carbon steel. As the highest grade available within the carbon chain category, G70 offers a significantly higher strength-to-weight ratio than Grade 30 or 43 chains.
Coated in a highly visible gold chromate finish. This allows transport inspectors, DOT officers, and riggers to instantly identify the chain grade and verify load securement compliance.
Purpose-built to withstand severe abrasion against truck beds and cargo edges. Ideal for flatbed trailer tie-downs, heavy equipment securement, logging, and heavy towing.
