| Name | Feature | Specification | Picture |
| 2B | Bright | After cold rolling ,by heat treatment ,pickling or other equivalent treatment and lastly by cold rolling to given appropriate luster. | |
| BA | Polishing ,mirror | Processed with bright heat treatment after cold rolling | |
| Hairline | Line like hair | Hair grain grinding by appropriate particle size of material | |
| 6K/8K | Mirror, brighter than BA | Very bright, grinding and polishing surface by 1000# strop grain of abrasive belt |
Finish:BA,2B,2D,No.1,No.4,8k
BA – processed with bright heat treatment after cold rolling.
2B – after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to given appropriate luster.
2D – matt finish, best choice for deep drawing.
No.1-finished by hot rolling,annealing and packing,characterized by white pickled surface.
No.4-Polishing with No.150 to No.180 mesh abrasives.
