Cold Rolled Carbon Steel Coils - JISG3141
Cold rolled steel is steel rolled at room temperature, below its re-crystallization temperature, making it easier to control the steel’s shape, thickness, dimensions and surface finish. Cold rolled steel coil and sheet is best used where thickness tolerances and surface condition are important. Cold-rolled steel coils are widely applied to automobiles, electrical appliances, steel office equipment, containers, and numerous other products closely connected to pour daily lives.

Advantages:Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required. Until now, cold rolled coils have been available and successfully used for a variety of applications.
