| No.2D | Annealing and pickling are performed after cold rolling; material is soft with surface of silver-white luster; used for general applications and deep drawing. |
| No.2B | After 2D finish, skin pass rolling is performed to obtain a more suitable luster; the surface becomes very exquisite; used for general applications. |
| No.3 | Intermediate 100-120 grit finish; used for applications in which surface polishing is performed after shaping. |
| No.4 | General 150-180 grit finish; used for restaurants and kitchen equipment and tools. |
| #240 | 240 grit finish; used when a finer finish than No. 4 is required; typically for restaurants and kitchen equipment and tools. |
| #320 | 320 grit finish polished product. |
| HL | This finish is performed by continuous linear polishing using an abrasive of appropriate grain size; mainly used for architectural applications. |
| BA | Achieved by performing bright annealing after cold rolling and then skin pass rolling to obtain even greater reflectance; provides excellent corrosion resistance; used for household appliances, kitchen equipment, and automobiles. |
