Cold Rolled steel

Cold rolled steel is made by removing the oxide layer of hot rolled steel through acid pickling and rolling it at room temperature. Compared with hot rolled steel, its thickness is more even, and its surface is smoother. It is glossy and sufficiently withstands pressure. It can be processed even though it is long. Its universality is good. It is used to manufacture automobile bodies, electronic equipment, home appliances, architecture, and office supplies.
