FIRE DOORS
Fire doors serve as critical life safety components, designed to protect people and property in the event of a fire. At Priority Door Systems, we understand the unique requirements of fire door manufacturing, installation, and inspection. Our team is fully trained to ensure every door meets code, functions properly, and delivers the safety and security your building depends on.
HOW TO CHOOSE THE FIRE-RATED DOORS
How to choose the right Fire-Rated Door?
Check the local building code and the authority having jurisdiction to determine the rating of the fire door you need.Fire Label: Will need to be attached. This is the agency approved certified or labeled doors, frames, and anchors for minimum ratings required by code.
Fire Ratings by Hour & Letter-Designation
- Class “A” (3-hour)-Openings in firewalls that divide a single building into fire areas.
- Class “B” (1 hour)-Openings in enclosures of vertical shafts and stairwells through buildings and in 2 hour rated partitions providing horizontal fire separations
- Class “C” (3/4 hour) – Openings in walls or partitions between rooms and corridors having a fire resistance rating of 1 hour or less.
- Class “D” (1 1/2 hour) – Openings in exterior walls subject to severe fire exposure from outside the building.
- Class “E” (3/4 hour) – Openings in exterior walls subject to moderate or light fire exposure from the outside of the building.
- No letter designation (1/2 or 1/3 hour) – Openings in walls or partitions between rooms and corridors having a fire resistance rating of 1 hour or less. Note that these doors are not really considered fire doors, but rather used for smoke control only.
11 INSPECTION STEPS
These steps ensure your fire doors meet all safety and code requirements. From hardware integrity to proper sealing and alignment, we thoroughly assess every component to keep your facility protected and compliant.

Door clearances at the door edges to the frame on the pull side of the door do not exceed clearances.
Sixth Step
The self-closing device is operated by verifying that the active door will completely close when in the full open position.

Ninth Step
Auxiliary items, which may interfere with the operation of the door(s) are not installed on the door or frame.

Fire Doors are critical when seconds count. Every opening requires a combination of door components to offer the best protection. These components, when used in combination will meet the rating (45 min, 90 min, etc):
- fire door
- frame
- fire exit hardware
- door closers
- hinges
- locks
- door bolts
- and other door components
