ld Rolled steel sheetsand cold rolled steel coil have many uses. The basic process for creating cold rolled steel has been around for a long time. The basic process is rolling steel after it cools off from the Hot Rolled Steel process. With improved technology, we are able to be more precise than ever. On a basic level, one of the main results of the cold rolled steel sheet process is minimizing the thickness of the hot rolled steel, as well as increasing the durability.
