What is a fire rated door?

By definition, fire-rated doors are an entryway or door manufactured with the purpose to resist spreading fire if any part of your commercial structure catches fire. Fire rated doors in a kitchen slow down the spread of fire to other areas when closed.

CDF distributors proudly carries the largest variety of commercial fire rated doors in the industry. The most popular door sizes of hollow metal doors, wood doors, glass doors and louver options are always in stock - available, ready for super rush shipping to your job site.

Commercial Fire Safety

All commercial properties in the United States must be inspected annually by the National Fire Protection Association. Additionally, the underwriters laboratory agency determines whether a specific door model meets acceptable fire resistance ratings within the country. 

CDF's metal doors (both single and double doors) ratings consist of 20 minutes, 45 minutes, 90 minutes or a 3-hour rating. CDF distributor's fire rated wood doors come with three options: 20, 45 and 90 minute ratings.

These time-based tests are based on the timed exposure of flames the door and assembly can handle; examining the hardware, wall and door assembly as written in the building code standards. The doors are put into a large furnace to properly test the door against its specific rating.

When you choose a door model, "UL 20" indicates that it has undergone testing for 20 minutes of fire resistance.

Materials Used in Fire Rated Metal Doors

Our hollow metal doors and frames meet specific UL safety ratings for fire protection standards.

Example materials used to make our doors include galvanized, galvannealed, cold rolled, and hot rolled steel materials. Each of our doors undergoes rigorous testing for fire resistance, including closing devices and other components.

Fire Rated Door Labels

All fire rated doors within the United States must be labeled with a permanent label which must remain legible. In addition to fire rated doors, fire rated door frames must also include a permanent readable label.

While each door manufacturer must meet the UL criteria and are often part of a standards organization like the Steel Door Institute, hollow metal door ratings and tests are conducted by independent, internationally known labs.

Fire Rated Doors Aesthetic Appeal

When designing your building's experience, consider details and materials for both function and aesthetics. To meet most fire requirements, you do not have to sacrifice aesthetics for safety.

CDF distributors always keep commercial fire rated wood in stock, however, if these typical-fire-safe-doors do not fit the design of your building's corridors, we also offer wired glass and clear high-temperature fire rated glass options.

CDF distributors offer fusible link louvers for added ventilation in closed-off rooms or mechanical closets during fires.

We provide everything to make sure your building's hallways, stairwells, and other corridors are matching to fire code requirements.

Checking Building Codes For Fire Doors

Building codes specify fire resistance ratings for walls and fire door assemblies based on location and type.

Door type requirements depend on building use and occupancy levels. Always ask your building professional for more information. Be sure to always check with your local building code authority to confirm fire door requirements in your location before the unthinkable happens.
