Cold-rolling is a process of manufacturing metal plates, which is opposite to hot rolling. For the cold-rolling, the metal blank is treated with a cold-rolling machine to reduce the thickness of the plate, improve the surface quality, and adjust the hardness and mechanical properties of the material.

The main advantages of cold-rolled technology are that it can improve the surface quality while maintaining the strength and reducing the thickness of the raw material. It makes cold-rolled plates applied to applications that require higher flatness and surface quality, such as automotive manufacturing, electrical manufacturing, construction, and some special engineering projects.
