Steel Door Fire Ratings
Fire rated doors are specialized doors designed to resist the spread of fire and smoke within a building, providing crucial protection for occupants and the property. These doors are constructed using materials and designs that have been tested and certified to withstand fire for a specified period, typically measured in minutes. Fire ratings range from 20 minutes to 3 hours and Hollow metal is the only door material widely available with a 3 hour label.
20 Minute Fire Label
Used in one-hour rated walls to separate corridors where smoke and draft control are a possible issue
45 Minute Fire Label
Required in one-hour rated walls that serve as room partitions or divide corridors within a building. Installed in exterior door openings, particularly where there is a possibility of light to moderate fire exposure from the outside
90 Minute Fire Label
Required in two-hour rated wall openings to stairwells, elevator rooms, or egress through a building. Used in exterior openings where there is a potential for severe fire exposure from outside.
3 Hour Fire Label
Usually required in four hour rated walls that separate buildings or that divide a large building into smaller fire areas.
Steel Door Institute Fire Rating Requirements
