Stainless Steel Doors

The Stainless Steel Advantage

Design professionals generally specify stainless steel doors and frames for their sleek appearance. Stainless steel is also the optimum door material where rust and corrosion are a concern. They are also very hygienic. For these reasons, they are found in a wide variety of buildings such as offices, hospitals, and food processing plants, to name a few.

Stainless steel doors typically have a composite core such as polystyrene or honeycomb, but are also available with steel stiffeners. They can be fire and STC rated too.

Stainless Steel Door Design

There are many finishing options, enabling architects to add a distinct design element to their doors. Standard industry finishes are referenced by #1-8. Lower number finishes are more matte, while higher numbers are more reflective. The most common finishes include:


#2B Unpolished

Suitable for painting, such as in concealed areas where stainless steel performance is required but aesthetics are not important


#4 Brushed Satin

Low reflectivity


#6 Long Grain Satin

More reflective than a #4 finish

#8 Mirror

Highly reflective where fine polishing lines are barely visible. Fingerprints show on mirror-like finishes, so they are best-suited for low traffic openings

… and many more such as angel hair, swirl and distressed
