Stainless Steel Finishes Guide
There are a variety of finishes available on stainless steel sheet, and we stock three of the most popular ones here at Cut2Size Metals.
- Top to bottom: #8 Polish, #4 Finish, 2B Mill Finish
#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 Cut2Size Metals baseball bat in the photo, the polishing results in a true mirror-like finish.
Stainless Steel Sheet alloys available with the #8 Mirror finish: 304
#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.
Stainless Steel Sheet alloys available with the #2B finish: 304, 316, 430
