What’s the Cold Rolled Steel Coil

The cold-rolled steel sheet is rolled at room temperature, which is lower than the recrystallization temperature, which can better control the shape, thickness, size and surface brightness of the finished product

Cold rolled steel is essentially hot rolled steel that has undergone deep processing. The steel is further processed in a cold reduction mill, where the material is cooled (at room temperature), then annealed and/or tempered and rolled. This process will produce steel with smaller dimensional tolerances and a wider range of surface finishes. The term cold rolled is wrongly used on all products, but in fact the product name refers to rolled flat steel and coil products
