Guide to Stainless Steel Finishes

Posted in: Guides October 7, 2009 - by J. Andrew Hubbard

There are a variety of finishes available on stainless steel sheet, and we stock three of the most popular ones here at  [We can get others as well, so if you don't find what you're looking for, give us a call at 812.429.1634].

#8 Mirror Finish 

The #8 Mirror finish is a polished, highly reflective finish with the grain marks polished out. It is closest to the top in the picture above.  As you can see from the reflection of our warehouse ceiling in the piece, the polishing results in a true mirror-like finish.

#4 Polish 

The #4 Polish finish has a 150-180 grit grain in one direction. This finish is often used when the material is subject to rough handling, such as restaurant equipment.  It is in the middle in the picture above.  When we cut #4 polished stainless for you, the grain will run whichever way allows us to utilize the material best.  If you need a certain grain direction on your pieces, please call and let us know.

2B Finish 

The 2B finish is a bright, cold-rolled industrial finish with no grain pattern. This is the standard industrial finish you'll find on stainless steel sheet.  It is closest to the bottom in the picture above.  It is bright, but not polished like the other finishes.
