Stainless Steel Finishes

Stainless steel finishes we offer:

There are many types of stainless steel finishes. Each technique requires a varying level of labor required to achieve. Furthermore, each technique can create an entirely different look. When specifying stainless steel finishes, it’s important to understand that each finish type requires a different degree of labor which will affect the cost. Some popular stainless steel options we offer are shown below:

What are four popular stainless steel finishes for railings?

The most popular types of finishes for stainless steel railings are #4 Polish (Brushed Finish), #6 Polish (Fine-Brushed Finish), #8 Polish (Mirror Finish), and Matt Finish (Bead Blast).

What is #4 Polish (Brushed Finish) Stainless Steel?

Sometimes called a line finish, this polished stainless steel option is achieved by sanding in a vertical direction using 150-180 grit abrasive sandpaper. This is one of the most common stainless steel finishes used in architectural metalwork. You can see an example of a #4 polished railing here. Stainless Steel Keuka style cable railing posts.

What is #6 Polish (Fine Brushed Finish) Stainless Steel?

A #6 polished railing will have a finer grain finish with a brighter sheen than a #4 finished railing. Fine-brushed polished stainless steel requires the same sanding but also must be buffed with a buffing compound on a cloth wheel. The quality of the surface depends greatly on the amount of sanding done and the fineness of the abrasives used.

What is #8 Polish (Mirror Finish) Stainless Steel

As the name implies, a mirror polish will result in a highly reflective finish. Mirror polishing requires a significant amount of buffing to achieve. While polishing, great care must be taken to remove deep scratches. Any defects will show through and be quite noticeable once you reach the final stage. One benefit of mirror-polished stainless steel is that the finishing process improves its corrosion resistance. This is because it removes crevices where corrosion-causing chlorides can sit and do their work.

What is a Stainless Steel Matte Finish (Bead Blast)?

A bead blasting process provides a dull, matte finish. For the best results, glass beads are used. The stainless steel matte finish is relatively cost-effective and has a nice uniform appearance. One drawback, however, is it is susceptible to fingerprint staining.
