No. 1 |
Hot rolled
Annealed and discased. Produced by hot rolling followed by annealing and resealing. Generally used in industrial applications, such as for heat or corrosion resistance, where smoothness finishing is not of particular importance. |
2B |
Cold rolled
This is produced as 2D finish, but a final light rolling using highly polished rolls gives the surface a smooth, reflective, grey sheen. This is the most widely used surface finish in use today and forms the basis for most polished and brushed finishes. |
Hairline |
Cold rolled
Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
BA |
Cold rolled
Bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
8K |
Cold rolled
The product have excellent brightness and prefer reflexivity can to be the mirror. |
