| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better brightness and flatness than NO.2D, with improved mechanical properties through special surface treatment for comprehensive uses. |
| NO.1 | Surface finished by heat treatment and pickling after hot rolling. |
| NO.4 | Polished with abrasive belt grit #150-#180, featuring better brightness with discontinuous coarse striations. Used for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with abrasive belt grit #150-#320 on NO.4 finish with continuous streaks. Primarily used for building ornaments, elevators, building doors, and frontal plates. |
| BA | Cold rolled, bright annealed and skin-passed with excellent brightness and mirror-like reflexivity. Ideal for kitchen apparatus and ornaments. |
| 8K | Excellent brightness and superior reflexivity, can be used as a mirror. |
| Property | Value | Property | Value |
