How to use Grade 70 Transport Chain

Transport Chain is a standard link grade 70 chain made using high-strength / low-alloy carbon steel. The process that gives high grade transport chain it's strength is heat treating process. The combination of material and heat treating provides a more suitable chain strength for stabilizing heavy loads. All of our chain is plated with yellow zinc chromate finish and proof tested to ensure the load ratings. Grade 70 chain is rated approximately 20% higher than High Test Grade 43 Chain and has become the most common grade of chain used in flatbed tie downs today. Truck drivers have many names for this type of transport chain calling it binder chain, binding chain, boomer chain, load chain, and coil chain.
