Audited Supplier Hot rolled steel coil is used as raw material, after pickling to remove the oxide skin, cold continuous rolling is carried out, and the finished product is rolled hard coil.
The hard rolled coil is annealed to become a cold rolled coil.

| Bright Annealed | Black Annealed |
| The biggest difference between black regression and heating is that it is not in contact with the air, with nitrogen and other inert gases have been protected, the surface color is maintained and the same as cold rolled strip steel, in addition to the use of black regression is also used for surface tinning and other surface treatment, beautiful and generous. | The cold rolled strip is heated directly to the annealing temperature, and the surface color turns black due to high temperature contact with air. The physical properties become soft, and it is generally used for steel strip repressing, stamping, and deep processing with large deformation. |
