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.
