Grade 30, or "Proof Coil" chain is electrically welded from low carbon steel. Grade 30 is a durable, economical utility chain for applications which do not require a high strength to weight ratio. It has a wide range of applications throughout industry and agriculture, including logging, guard rails and towing. When galvanized it also has many marine applications. Note: Proof Coil is a carbon chain and should never be used for overhead lifting.
