Stainless Steel Finishing Options

Your application requirements will largely determine the type of finishing options you need. Some applications will require finishing that provides enhanced corrosion resistance while other applications will require finishing that smooth surface finishes. Finishing options are numbered one through eight, with higher numbers being more reflective than lower numbers. Lower numbers have a more of a matte finish whereas higher numbers have a reflective, polished finish.

Stainless Steel Mill Finishes

Mill finishes offer a matte finish for stainless steel. It is ideal for applications that do not require bright finishes or where durability remains the most important factor.cold rolled stainless steel with BA finish

#1D Finish

Hot-rolled, annealed and pickled with a coarse surface

Suitable for structural projects and support projects

#2D Finish

Cold-rolled, annealed and pickled, with a dull matte appearance

Ideal for gutters and drainage applications

#2B Finish

Cold-rolled, annealed and pickled, with a bright/high polish appearance

Well-suited for solar panels and architectural applications

304 and 316 ss grades often come with a 2B finish

BA Finish

Cold-rolled, bright annealed with smooth reflective surface

Similar to #8 mirror finish

Ideal for fabrication projects

Stainless Steel Brushed Finishes

Brushed finishes offer a reflective option with parallel or patterned lines. Brushed finishes are often used for buildings and architectural applications.

#3 Finish

100-120 grit

Coarse grain finish

Suitable for high traffic areas/applications

#4 Finish

150-180 grit

Bright brushed finish

Works for architectural/aesthetic projects

Stainless Steel Polished Finishes

Hot rolled, then buffed, polished stainless steel finishes are highly reflective with a mirror-like shine.

#8 Mirror Finish

Reflective and polished

Ideal for ornamental applications and structures

Differences between Brushed Stainless Steel and Polished Stainless Steel

Brushed stainless steel finishes can vary due to different abrasive techniques and sanding belt differences used for brushed stainless steel products. #4 finish offers more reflective qualities and lines than the #3 finish.

Brushed stainless steel finishes have a dull lustered appearance whereas polished stainless steel has a bright, mirrored finish.

Polished stainless steel finishes are mirror-like with a highly-reflective appearance.

Which Stainless Steel Finish is the Best Type of Finish?

The best stainless steel finish will depend on your project requirements. Matte finishes are suitable for industrial uses that do not require smooth surface finishes. Highly reflective polished finishes are well-suited for aesthetic and ornamental uses.
