The round link steel chains have become a proven standard in aggressive mining, ash handling, cement production, and other heavy-duty applications due to their high strength and flexibility in operation.
They are built to meet or exceed the German Institute for Standardization (DIN) for dimensional consistency, interchangeability, and correct sprocket engagement, most commonly with the DIN 22252 & DIN 764 specifications. They are offered in both the standard hardness state (through-hardened) or with upgraded surface hardness (case-hardened) to best combat abrasive wear.
