Grade 30 proof coil chain is a light to medium duty hardware chain designed primarily for applications such as agriculture, construction, marine, and automotive. Grade 30 chain is NOT approved for overhead lifting. We offer grade 30 chain in sizes 3/16" – 1/2" and is available by the foot or in bulk drum quantities.

Graded chain such as our 30 type is easily identified by the number markings found on the chain links themselves. These marking are not typically found on every link; however, they are more commonly spaced every 10” - 16”, or every so many links depending on the manufacturer. All graded chain is required per NACM specifications to have the grade marking stamped on the chain links so that the user can easily identify the grade type of the chain. We stock grade 30 chain, grade 43 chain, grade 70 chain, grade 80 chain, grade 100 chain, and grade 120 chain. In addition to our bulk graded chain, we offer a full range of graded chain fittings including grab hooks, slip hooks, coupling links, twin clevis links, and more.
