Definition of cold rolled sheet
Cold-rolled coils are rolled at the temperature below the recrystallization temperature at room temperature, including rolls and rolls. Among them, the delivery is called steel plate, also known as box plate or flat plate; the long length of delivery is called steel strip, also known as coil.

Definition of cold rolling
It is a rolling under recrystallization, but it is generally understood to be rolling at room temperature. Aluminum cold rolling is divided into plate rolling and foil rolling. The thickness above 0.15~ is called plate, and 0.15~ below is called foil. In Europe and America, 3~6 continuous rolling mills are used as cold rolling equipment.
Because there is no heating in the production process, there are no defects such as pitting and iron oxide that often appear in hot rolling. The surface quality is good and the finish is high. Moreover, the dimension accuracy of cold rolled products is high, and the performance and organization of products can meet some special requirements, such as electromagnetic performance and deep drawing capability.
Specifications: thickness is 0.2-4mm, width is 600-2 000mm, steel plate length is 1200-6 000mm.
