| Surface | Feature | Summary of Manufacturing Method | Use |
| NO.1 | Silver white matt | Hot rolled to the specified thickness, on a rough, matte surface that has been annealed and dephosphorized | No need for surface gloss purposes |
| NO.2D | silver white | After cold rolling, heat treatment and pickling are carried out, and sometimes the matte surface is processed by the final light rolling on the rough surface. | 2D products are used for applications that do not require strict surface requirements, general materials, and deep drawing materials |
| NO.2B | Stronger gloss than NO.2D | After NO.2D treatment, the polished roller is used for the final light cold rolling to obtain a suitable gloss. This is the most commonly used surface processing, and this processing can also be used as the first step of polishing | General materials |
| BA | Bright as a mirror | There is no standard, but it is usually bright annealed surface processing, with high surface reflectivity | Building materials, kitchen utensils |
| NO.3 | Rough grinding | Grind NO.2D and NO.2B materials with 100~200# (unit) grinding belts | Building materials, kitchen utensils |
| NO.4 | Intermediate grinding | The polished surface obtained by grinding NO.2D and NO.2B materials with 150~180# stone abrasive belts. This is a general purpose, with a mirror-reflected bright surface with visible “grains” | Same as above |
