Proof Coil Chain is a light to medium duty chain commonly used in the agriculture, automotive, and marine industries. This Grade 30 Chain is made from Type 316 stainless steel and is considered marine grade. T316 stainless steel contains molybdenum, which makes it resistant to ocean water mist or spray, so it's especially useful in extreme conditions with moisture or high chloride environments.
Type 316 proof coil chain has a smooth finish, so it’s comfortable and easy to handle when hand pulling items like boat anchors or when using it as a tie-down chain.
We also offer a stainless steel proof coil chain made from Type 304 Stainless Steel. While it's resistant to rust and oxidation, it should not be used in extreme conditions where chlorides like seawater are present.
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.
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.
Check out our chain category page for more information on the different types of chain grades available.
