Our USA-made grade 100 chain is a heat-treated steel chain with a high strength-to-weight ratio, which makes it safe for overhead lifting and lifting slings. It may also be used as a recovery, safety, or towing chain. Grade 100 chain is sometimes used to secure heavy duty industrial loads.
Grade 80 chain is sometimes used in place of grade 100 chain. It provides approximately 25% lower work load limits than grade 100 chain and is approved for overhead lifting applications as well.
