Stainless Steel Coil 2D Finish:
A dull finish which results from cold rolling followed by annealing and descaling, and may perhaps get a final light roll pass through unpolished rolls. A 2D finish is used where appearance is not a concern.
Stainless Steel Coil 2B/ mill finish:
A bright, cold-rolled finish resulting in the same manner as 2D finish, except that the annealed and descaled sheet received a final light roll pass through polished rolls. This is the general-purpose cold-rolled finish that can be used as is, or a preliminary step to polishing.
Stainless Steel Coil BA(Bright Annealed)
The bright annealed mill surface is obtained by annealing the material under an atmosphere, so that scale is not produced on the surface.
Stainless Steel Coil Brushed Finish (No.3/No.4/No.5/No.6):
This is a ground unidirectional finish obtained with 150/180/240/320 grit abrasive, which is characterized by parallel brushing lines, it is also known as Satin.
