Grade 70 chain
Grade 70 and 75 chains are coated with yellow-carbon alloy steel. Which protects the chain from corrosion and is made of heated carbon steel. This feature makes it recognizable from a distance.
This chain can be used as a hoist chain in chain lifts and it should be noted that the chain is vertically stretched and its use is not allowed. This chain is used for transporting and moving cargo. Sometimes a yellow plate is attached to distinguish these chains from others.
