1. Fire Resistance:
Fire rated steel doors are specifically designed to withstand exposure to high temperatures and flames, serving as a barrier to prevent the spread of fire and smoke. They are rated in minutes (e.g., 30, 60, 90 minutes) based on their ability to resist fire.
2.Durable Construction:
These doors are made of steel, which provides excellent strength and durability. Steel is highly resistant to heat and fire, making it an ideal material for fire-rated doors.
3.Fire Testing:
Fire rated steel doors undergo rigorous testing to ensure they meet fire resistance standards set by organizations like Underwriters Laboratories (UL) or the National Fire Protection Association (NFPA).
4.Intumescent Seals:
Many fire rated steel doors feature intumescent seals around their edges. These seals expand when exposed to heat, effectively sealing gaps and preventing the passage of smoke and hot gases.
5.Self-Closing and Self-Latching:
Fire rated doors are equipped with self-closing and self-latching mechanisms, ensuring they automatically close and latch during a fire event, maintaining their integrity and preventing the spread of fire.
6.Fire-Rated Hardware:
The door's hardware, including hinges, locks, and handles, is typically fire rated and designed to withstand the effects of fire, ensuring that the door functions as intended during an emergency.
7.Smoke Control:
Some fire-rated steel doors also provide smoke control by blocking the passage of smoke, which is equally dangerous as the fire itself.
