Brief of Product
Made from hot rolled steel coil by pickling off hot roll black skin (surface crust) and rolling under flow temperature, as it is not heavily rolled and is without heating so gain the name of cold rolled steel coil.
Cold rolled steel coil can roll steel thinner than hot rolled steel coil with high dimensional precision. After pickling, the surface is fine, shining and free of oxidized crust. Through different process controls, it can produce various surface conditions and coating and plating treatment, such as coating, electroplating and lamination, …etc, to expand and extend the application of products as required by different industries.
