| Surface | Characteristic | Summary of Manufacturing Method | Application |
| NO.1 | Silvery white | Hot rolled to specified thickness | Do not need to have a glossy surface use |
| lackluster | |||
| NO.2D | Silvery white | After cold rolling, heat treatment and pickling are carried out | General material, deep material |
| NO.2B | Gloss is stronger than No.2D | After No.2D treatment, the final light cold rolling is carried out through the polishing roller |
The general material |
| BA | As bright as a sixpence | No standard, but usually a bright annealed surface with high reflectivity. | Building materials, kitchen utensils |
| NO.3 | Rough lapping | Grind with 100~200# (unit) strop tape | Building materials, kitchen utensils |
| NO.4 | Intermediate grinding | Polished surface obtained by grinding with 150~180# strop abrasive tape |
Building materials, kitchen utensils |
| NO.240 | Fine lapping | Grinding with 240# strop abrasive tape | kitchenware |
| NO.320 | Very fine grinding | Grinding was carried out with 320# strop abrasive tape | kitchenware |
| NO.400 | The luster is close to BA | Use 400# polishing wheel to grind | General timber, building timber, kitchen appliances |
| HL | Hairline grinding | Suitable particle material for hair stripe grinding (150~240#) with many grains | Building, construction material |
| NO.7 | It's close to mirror grinding | Use a 600# rotary polishing wheel to grind | For art or decoration |
| NO.8 | Mirror ultrafinish | The mirror is ground with a polishing wheel | Reflector, for decoration |
