China Steel Glass Fire Rated Door Manufacturers - High-Quality Fire Rated Door Suppliers from Factory

Steel glass fire rated doors combine high-strength galvanized steel frames with specialized fire-resistant glass. This unique structure provides robust fire protection and smoke containment while maintaining high light transmission and a modern, aesthetic appearance.

The grades represent the door's fire integrity and insulation duration. Grade C protects for ≥30 minutes (ideal for pipe shafts), Grade B protects for ≥60 minutes (suitable for stairwells and evacuation routes), and Grade A protects for ≥90 minutes (designed for critical areas like fire control and power distribution rooms).

Yes. Our doors support electrostatic powder coating in a wide selection of colors from the RAL color chart, as well as wood grain heat transfer printing to simulate premium textures like oak and walnut.

The doors feature a precisely controlled gap of 1–3 mm and are equipped with automatic door closers. Under high temperatures, the specialized fire-sealing strips expand rapidly to seal all remaining gaps, effectively preventing toxic smoke from passing through.

Maintenance is straightforward. Regularly inspect the hardware for smooth operation, clean the sealing strips to ensure they remain clear of debris, and replace any worn-out or damaged components individually to extend the door's service life.
