#1 FINISH
This rolled sheet finish is produced by hot rolling followed by annealing and descaling. This is used for industrial, not architectural metal or ornamental metal, applications.
#2B FINISH
This is a dull finish used almost exclusively in industrial applications. It is cold rolled, annealed and descaled, with a final light cold roll pass on polished rolls. This finish is more able to be polished to a high luster than either #1 or #2D.
#2BA - BRIGHT ANNEALED FINISH
This is a bright annealed finish with a mirror-like appearance produced by cold rolling, then annealing in a controlled atmosphere furnace. This finish is sometimes specified for architectural applications.
#2D FINISH
This is a dull finish that offers no reflectivity. It is produced by cold rolling annealing and descaling. The #2D finish helps retain lubricants and is generally preferred for deep draw articles that will be polished after fabrication. |
