Cold Rolled Steel
Cold rolled steel is made using hot rolled steel through pickling, cold rolling and heat treatment. It is relatively thin with a thickness of 0.15 mm to 3.00 mm. Cold rolled steel is highly aesthetic and easily machinable, thus widely used for premium applications in modern society. We have increasingly focused on offering value-added products as demand for highly functional, cold rolled products is rising.
