An FD rating defines how long a fire door can withstand fire exposure while helping prevent the spread of fire and smoke.
What Does FD Mean?
FD stands for Fire Door rating, and the number represents the duration of fire resistance in minutes:
- FD30 – 30 minutes of fire protection (offices, commercial spaces, internal fire separation)
- FD60 – 60 minutes of fire protection (industrial buildings, warehouses, electrical rooms)
- FD90 – 90 minutes of fire protection (high-risk industrial areas, technical rooms)
- FD120 – 120 minutes of fire protection (data centres, power facilities, industrial plants)
- FD180 – 180 minutes of fire protection (heavy industrial facilities, high-risk fire zones)
How to Choose the Right FD Rating?
Select based on building type, fire risk level, installation location, and required safety standards.
