Surface Treament:
| Surface Finish | Definition and Application |
| NO.1 |
The surface is finished by heat treatment and pickling or processes corresponding there to after hot rolling |
| 2D | The finishes after cold rolling, by heat treatment, pickling or other equivalent treatment |
| 2B |
The finishes after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster |
| BA |
Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror |
| NO.3 | Polished with abrasive belt of grit#100~#200,have better brightness with discontinuous coarse stria |
| NO.4 |
Polished with abrasive belt of grit#150~#180, have better brightness with discontinuous coarse stria |
| HL | Polished with abrasive belt of grit#150~#320,have better brightness with discontinuous coarse stria |
| 8K | The product have excellent brightness and perfect reflexivity, can be the mirror |
