Surface Treatment Options
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Superior brightness and flatness compared to NO.2D. Enhanced mechanical properties through special surface treatment, suitable for comprehensive applications. |
| NO.1 | Heat treatment and pickling finish after hot rolling process. |
| NO.4 | Polished with #150-#180 grit abrasive belt. Features better brightness with discontinuous coarse striations. Ideal for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with #150-#320 grit abrasive belt 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. Excellent brightness and mirror-like reflectivity. Suitable for kitchen apparatus and decorative applications. |
| 8K | Excellent brightness and superior reflectivity, achieving mirror-like quality. |
