    HVG LINK CHAINS 0006: Grade 70 Transport Chain

    • Grade 70 transport chain is a kind of welded carbon steel link chain. The chain is an improvement over high test chain. Load ratings of grade 70 chain are approximately 20% higher than grade 43. Grade 70 transport chain meets ASTM and NACM standards. The chain is most popular in the cargo industry as trailer tie downs, however the chain is not used for overhead lifting purposes.
    • The grade 70 transport chain generally features a gold chromate finish, which makes it easily identifiable. Besides, it is usually embossed with 7, 70, or 700.
    • In addition to grade 70 transport chain, grade 43 high test chain, grade 30 proof coil chain, grade 80 alloy chain, and grade 100 alloy chain are all available.
