BA - processed with bright heat treatment after cold rolling.
2B - after cold rolling, by heat treatment, pickling or other
equivalent treatment and lastly by cold rolling to given
appropriate luster.
2D – matt finish, best choice for deep drawing.
No.1-finished by hot rolling,annealing and packing,characterized by
white pickled surface.
No.4-Polishing with No.150 to No.180 mesh abrasives.
