The cold rolled sheet is manufactured from the hot rolled sheet. The hot rolled sheet is cleaned chemically and processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. Cold rolling increases strength, enhances the surface finish and offers uniform thickness. To prevent the cold rolled coils from rust, they are usually coated with a thin layer of oil. Further coating of Zinc-Aluminium alloy or galvanization on the metal can be processed. HUARO Steel offers cold rolled coils in a range of international standard grades. As one of the professional cold rolled steel sheet suppliers, HUARO offers high-quality cold rolled steel sheet for sale, come and buy cold rolled steel sheet at HUARO.
The cold rolled sheet as known as CRS. The CRS is made of hot rolled steel products. The cold rolling process helps to obtain the Cold Rolled Steel Sheet from the cooling (in the cold rolling mill) of hot rolled pickled products (made from finest steel), which is reduced too much finer thickness with increased strength via strain hardening (up to almost 20%). The resulting Cold Rolled Steel Sheets are smaller as compared to the sheets formed by the hot rolling process, and they are less ductile. They possess improved surface finish and tighter tolerances.
