What is Cold Rolling Process？
Cold Rolling refers to a steel strip which is directly rolled by a roll to a certain thickness at normal temperature and wound up into a full roll by a winder.
Compared with hot rolled coil, the surface of the cold rolled coil is bright and has a high finish, but it generates more internal stress and is often annealed after cold rolling.
Performance: It is mainly made of low carbon steel grade, which requires good cold bending and welding performance, as well as certain punching performance.
Application areas: Cold-rolled strips are widely used, such as automotive manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc.
