The Grade 80 Chain is engineered from alloy steel with a black protective coating for greater durability and resistance to abrasion. These chains are mostly used for lifting applications. They can be made into strong and supportive chain slings that are more than ready to hoist up the heavy-duty loads with greater ease. The chains can also be used for securement applications, giving you greater strength to keep the load stabilized for transit. The Grade 80 Chain is available in 5/16” size with a working load limit of 4,500 lbs., in 3/8” size with a working load limit of 7,100 lbs., in 1/2” size with a working load limit of 12,000 lbs., and in 5/8” size with a working load limit of 18,100 lbs. Any of these chains can be used to your advantage, offering high-quality strength to get the job done right.
