- Product Description
-
Cold rolled steel coil (CR Coil) is a kind of steel with high mechanical properties and high surface smoothness made at room temperature. It has a smooth surface and a dimensional tolerance of ±0.02mm, and improves strength through work hardening. It is mainly used in automobile sound panels, electrical appliances, electronic product manufacturing, etc. The main grades are SPCC, DC01-06, Q195A-Q235A, ASTM, etc. Surface treatment processes such as oiling and passivation can be adopted. Compared with hot-rolled products, it has better formability and higher hardness and precision.

Cold rolled steel coil Application
Cold rolled steel coil are mainly used in industries that require small tolerances, smooth surfaces and high mechanical properties. It is suitable for auto parts, household appliances, furniture, office equipment, building materials, and precision instrument manufacturing. In addition, it has excellent formability and surface finish, and can also be used in pipes, containers, and metal stampings.
