WELDED STEEL CHAINS provide an economical and superior method for conveying most materials. They are most common in the lumber, pulp and paper, plywood, OSB and other board mills, bucket elevator and bulk material handling.
For higher impact strength and greater wear resistance, use fully heat treated or induction hardened chain.
