Grade 100 can be marked 10, 100, or simply may have anything with a 10 or 100 embossed on the link. There may be a letter before the number (like D10 or D100) which is usually a manufacturer’s ID code. 

Here at Advantage, our Grade 100 Alloy Chain is our own “BLUE CAT” Finish. Finishes vary by supplier. Grade 100 Alloy Chain can be Self Colored (no rust-proofing) as well.

Grade 100 is made from a different alloy and heat treating process than grade 80 Chain. As a result, X100 Grade 100 chain is stronger than Grade 80 Chain.

Grade 100 Chain is primarily used in Overhead Lifting (OHL) by crane operators, heavy equipment operators and in manufacturing. Other applications include high strength requirements such as Heavy Vehicle Recovery, pulling excavation equipment from mud, cargo control/tie down, etc.  

A fabricated rigging product, known as a Chain Sling, is fabricated, and inspected by a qualified individual, using products engineered for the agreed upon application. There are many different Chain Sling configurations (see a few examples below). Each Grade 100 Chain Sling has a unique rating that coincides with the grade and configuration.  

Rigging training is required when using Certified Chain Slings. It is required that Grade 100 Hooks and Components be used on Grade 100 Certified Chain Slings in order to maintain its Safe Working Load rating. Using components such as hooks that are Graded below Grade 100 (such as a Grade 70 or Grade 80 hook), shall make the Chain Sling out of compliance with OSHA Standards.

Grade 100 is approved by US DOT for use in Cargo Control on Interstate Highways.
