Stainless Steel Sheet Finishes
Stainless steel sheet is produced in many types of
finishes due to the various uses and applications that
stainless steel can be used in. It has become popular
in kitchens due to its low maintenance, cleanliness,
appearance, and corrosion resistance to food acids
and water.
For example, the most commonly used finish for most
stainless steel appliances is the No. 4 "Brushed"
finishes. This finish provides a nice bright, brushed
appearance that will withstand daily use and mask
the fingerprints, scuffs, scratches, etc.
2B (Bright, Cold Rolled)
A bright, cold-rolled finish is the most commonly "Mill" finish for light gauge stainless steel sheet. It
resembles a very hazy mirror, with some reflection evident. It is obtained by a final light roll pass of
the sheet through polished rolls. This is the general-purpose cold-rolled finish that can be used as
is, or a preliminary step to polishing. 2B sheets do not typically have any protective coating and
therefore may contain light marks from handling and shearing operations.
No. 3 (Brushed, 120 Grit)
An intermediate polished surface obtained by finishing with a 120-grit abrasive. A directional course
"grain" running in one direction. Used in heavy use areas or can be further polished after fabrication.
Our #3 polish stainless sheets come with peel off protective covering on one side that can be
removed after the material is installed.

Like the #3 finish, these sheets also come with a peel off protective coating on one side.
No. 8 (Mirror)
The most reflective surface of stainless steel commonly available, It is produced by polishing with
successively finer abrasives and buffing extensively until all grit lines from preliminary grinding
operations are removed. It is used for cosmetic applications such as mirrors and reflectors.
BA (Bright Annealed)
Sometimes confused with the No. 8 finish, although it is not as "clear and defect free" as the No. 8
mirror finish. This is obtained by annealing the material under an atmosphere so that scale is not
produced on the surface. This results in a highly reflective, mirror-like finish, without further polishing.
