Continuously Cold Rolled Coil

The surface presents a non-metallic inclusion in the form of dots, blocks or lines, which is intermittently or continuously distributed in the rolling direction, and has a color of good brown, dark gray or white. In severe cases, the steel plate has holes, cracks, and broken bands.

continuously cold rolled coil is mainly used for deep drawing quality,non-aging , such as auto parts and electrical parts which demand has higher ductility.
