No. 2B Finish is a bright cold rolled finish, produced very similarly to the No. 2D finish. The difference in the production lies in the final light cold rolling pass of a No 2B Finish, that is is done using polished rolls. This light cold rolling creates a more reflective finish, similar to a cloudy mirror. Finished reflectivity varies from manufacturer-to-manufacturer and coil-to-coil, with some coils having greater or lesser reflectivity. The No. 2B is a general purpose cold rolled finish and is commonly used for all but exceptionally difficult deep drawing applications. It is more easily polished to high luster than a No. 1 or No. 2D finish.
