Fire Doors are unique in their manufacturing, their installation and their inspection. Choosing a company that is trained in the proper installation and inspection process is critical to helping to you provide the safety and security you expect. Fire doors fall categories include:
- horizontal sliding

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
- fire exit hardware
- door closers
- door bolts
- and other door components
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 & by 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.
