Frequently Asked Questions
What are the primary features of a steel glass fire rated door?
Steel glass fire rated doors combine fire-resistant glass with a durable galvanized steel frame. They provide excellent fire resistance, smoke sealing, impact durability, and aesthetic customization (such as powder coating or wood grain transfer) while maintaining natural light transmission.
How do the different fire rating grades (Grade A, B, and C) differ?
The grades are classified by their fire integrity and insulation durations: Grade C offers ≥ 30 minutes of protection; Grade B offers ≥ 60 minutes; and Grade A offers ≥ 90 minutes. Higher ratings are reserved for critical utility rooms, while lower ratings are typical for pipe and cable shafts.
How does the smoke sealing mechanism prevent toxic gas spread?
The door gaps are kept tight (within 1–3 mm) and paired with an automatic door closer. Upon exposure to high heat, specialized fire-sealing strips expand rapidly to seal the gaps completely, blocking hazardous smoke and gas infiltration.
Where are these fire rated doors typically installed?
They are widely used in commercial buildings, public institutions (like hospitals and schools), industrial facilities, transportation hubs (airports and rail stations), and high-security military zones where both light transmission and fire safety are required.
Can the appearance of these doors be customized?
Yes. The steel frames support electrostatic powder coatings in various RAL colors as well as wood grain heat transfer printing (simulating wood textures like oak and walnut) to match modern architectural aesthetics.
What maintenance is required for steel glass fire doors?
Maintenance involves regular checks on hardware flexibility, cleaning the expansion sealing strips, and ensuring the door closer functions correctly. Damaged components can be replaced individually to extend the door's overall service life.
