WebCold-rolled steel is a product that has been cold reduced, as opposed to hot-rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape. The benefits of cold-rolled sheet is excellent performance in operations that require deep drawing and intricate bending and forming. WebSendzimir Mill (Z Mill) In a Sendzimir mill (also called a Z mill), steel is rolled in a 20-high roller configuration, which applies higher roll pressure and allows very hard and elastic materials to be rolled. Temperature monitoring ensures the steel is cooled sufficiently that it will not stick to and burn the separating paper when coiling.
