▣ COLD ROLLED STEEL
※ feature of product
Also called cold rolled steel sheet, the scale (rust) and impurities of the hot rolled coil are removed by pickling process, and the compressive force is applied in the vertical direction through a rolling mill to increase the thickness, and the hardened material is improved by heat treatment. It is a product that ensures workability, surface roughness and flatness.
The cold rolled product is generally used as a generic name for CR products that have only been pickled, rolled and heat treated as well as those that have been plated or surface treated. Unlike plating materials, cold rolled products do not have a layer that protects them from rust by the reaction of iron and oxygen in the air.
