Type 304 Stainless Steel Proof Coil Chain is a corrosion-resistant general-purpose chain. While it's resistant to rust and oxidation, it should not be used in extreme conditions where chlorides like seawater are present. We do offer a T316 stainless proof coil chain option which is suitable for marine applications.
Grade 30 chain is not approved for overhead lifting but it can still be used in tie-down applications. Proof Coil Chain is a general-purpose light to medium duty chain commonly used in the agriculture, construction, and automotive industries.
Grade 30 Proof Coil Chain links are embossed with 3, 30, or 300 and sometimes L3 grade markings. Grade 30 is not approved for overhead lifting.
More Chain Grade Options
With many chain options available, it’s important to know the differences between grades of chain to ensure you select the proper chain for your application. Every grade of chain has different uses but can generally be separated into three main categories: overhead lifting chain, transport chain, and other welded industrial chain types.
