Cold Rolled Steel
Cold Rolled Steel Plate for Automobiles, the Flagship of Steel Products As a product that hot-rolls steel plate 2mm or thinner at room temperature, cold rolled steel plate is also called 'the flagship of steel products,' since it is the most difficult to manufacture of all steel products and requires high technology. Thin and with beautiful surface, cold rolled steel plate is used as outer plate and interior material of automobiles, home electronics, construction materials, etc. that are closely related to our lives. HYUNDAI STEEL possesses an annual cold rolled steel plate production capacity of ten thousand tons and is lately striving to develop high-value-added cold rolled steel plates such as ultra-high strength steel plate in step with the worldwide trend for lightweight vehicles.
