Grade 70 1/4 inch chain is built to our highest specifications to handle intense heavy-duty applications. We construct our chain with durable, carbon steel chain and finish it with zinc-plated gold chromate for protection against rust and corrosion. The heat-treated carbon steel has been 100% proof-tested to twice its original working load limit so you can depend on it for years to come.
Grade 70 chain is made to NACM standards per Department of Transportation and CCMTA specifications for tie down use with properly marked links. We sell our 1/4-in. grade 70 chain in bulk barrels of 400-ft. of chain. The barrels are color-coded brown for easy identification.
