Cold rolled sheet  is a product made of hot rolled coil as raw material and rolled at room temperature below the recrystallization temperature, but it is generally understood as rolling using materials rolled at room temperature, and is mostly used in automobile manufacturing, electrical products, etc.
Process specifications
Due to the lack of heating during the production process, there are no defects such as pits and oxide scales that often occur during hot rolling. The surface quality is good and the smoothness is high. Moreover, the dimensional accuracy of cold rolled products is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic performance, deep drawing performance, etc.
Specification: The minimum thickness is 0.2-4mm, the width is 600-2 000mm, and the steel plate length is 1200-6 000mm.
Brand: Q195A-Q235A, Q195AF-Q235AF, Q295A (B) - Q345 A (B); SPCC、SPCD、SPCE、ST12-15; DC01-06
Performance: Mainly using low-carbon steel grades, requiring good cold bending and welding performance, as well as certain stamping performance.
purpose
Cold rolled sheet and strip have a wide range of applications, such as automotive manufacturing, electrical products, locomotives and vehicles, aviation, precision instruments, food cans, etc.
