Fire-Rated Steel Security Door for Data Centers & Equipment Rooms

This fire-rated door adopts a heavy‑duty all‑steel reinforced structure with high strength, stable performance and long service life. The door leaf and frame are made of hot‑dip galvanized steel sheets with strong anti‑corrosion and anti‑deformation performance. The surface is treated with electrostatic spraying, which is scratch‑resistant, dust‑proof and easy to clean, matching the clean environment of machine rooms.

The door leaf is filled with Class A non‑combustible fireproof core material, supporting fire ratings of 30min, 60min, 90min and 120min to meet different fire compartment requirements. It is equipped with a fire‑expansion sealing strip around the door leaf, which expands rapidly at high temperatures to block smoke and flame penetration. The door is equipped with heavy‑duty fire hinges, fire door closer and optional panic bar device, ensuring reliable self‑closing in case of fire and smooth emergency escape.

It supports anti‑static surface treatment with surface resistance controlled at 1.0×10⁶ ~ 1.0×10⁹ Ω, avoiding static damage to precision electronic equipment. The door features good sound insulation and airtightness, helping stabilize the temperature and humidity environment of the equipment room and reduce energy consumption of air conditioning. The modular design allows customized sizes, single/double leaf, left/right opening, with/without fire‑resistant glass viewing window, adapting to various machine room openings and installation conditions.
