Product Specification

The POSCO Quality

Cold Rolled

Cold rolled steel is made using hot rolled steel through pickling, cold rolling and heat treatment. It is relatively thin with a thickness of 0.2 mm to 2.0 mm. Cold rolled steel is highly aesthetic and easily machinable, thus widely used for premium applications in modern society. We are increasingly focused on offering value-added products as demand for highly functional, cold rolled products is rising.

This product specification is subject to change, so please check the latest specifications when ordering or consult with the person in charge.
