Fire door ratings are a critical aspect of building safety that every property owner, manager, and contractor should understand. These ratings indicate how long a door can withstand fire exposure while maintaining its structural integrity.
What Do Fire Door Ratings Mean?
Fire door ratings are expressed in minutes (20, 45, 60, 90, or 180) and represent the duration a door can resist fire. For example, a 60-minute rated door should withstand fire for at least one hour.
Common Fire Door Ratings
- FD30 (30 minutes): Suitable for residential and small commercial buildings
- FD60 (60 minutes): Common in commercial buildings and high-rise residential
- FD90 (90 minutes): Used in industrial settings and high-risk areas
- FD120 (120 minutes): Required for critical infrastructure and high-rise buildings
Choosing the Right Rating
The appropriate fire door rating depends on several factors including building type, occupancy, and local building codes. Always consult with a fire safety professional to ensure compliance.
