Frequently Asked Questions

What is stainless steel? Stainless steel is defined as a series of steel alloys which include at least 10% chromium. Dozens of stainless steel alloys exist. By far the most common alloy used in door production is #304 which is composed of 18% chromium and 8% nickel. The #316 alloy is used with success in highly chlorinated environments such as public swimming pools or pulp mills and is composed of 16% chromium, 10% nickel, and 3% molybdenum. Contact Penner Doors & Hardware in order to help you to select the stainless alloy most appropriate to your project.

What finishes can be applied to stainless steel? Three common finishes can be applied to stainless steel alloys. The #2B "mill finish" is an unpolished and hence less expensive product suitable for use in corrosive environments where appearance is unimportant such as industrial applications. The #4 "satin finish" is the most common type of polish suitable for use in a broad variety of applications. This finish is also known as a "32D finish". The #8 "mirror finish" is suitable for highly decorative environments. This finish is also known architecturally as a "32 finish".

As well, a range of colored stainless steels are available. The colors include a deep blue, a dark bronze, and bright brass. These colors are chemically bonded to the stainless steel and maintain their color for the life of the product. They are available in mirror or satin finishes.

Penner Doors & Hardware also offers a variety of patterned finishes which can be embossed, etched or applied to the stainless steel. Send us a drawing, template or physical sample so we can match your unique finish requirements.

Can stainless steel doors and door frames be fire rated? The fire rating capabilities of a particular manufacturer are limited to those products that have been laboratory tested by that firm. Our manufacturers' capabilities in the field of fire rated stainless steel doors and frames are the broadest in the industry. They include single door/door frame units rated to 3 hours. As well they include pairs of doors rated to 90 minutes.
