Design professionals generally specify stainless steel doors for their sleek appearance. Stainless steel is also the optimum door material where rust and corrosion are a concern. 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 may also be available with steel stiffeners. They can be fire and STC rated too.

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; 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.
