Cold rolled steel sheet production process

Since no heating is carried out during the production process, there are no defects such as pitting and iron oxide which are often caused by hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of the cold rolled product is high, and the performance and organization of the product can meet some special use requirements, such as electromagnetic performance, deep drawing performance and the like.

Specifications: thickness of 0.2-4mm, width of 600-2 000mm, steel plate length of 1 200-6 000mm.

Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06

Performance: It is mainly made of low carbon steel grade, which requires good cold bending and welding performance, as well as certain punching performance.
