Steel Glass Fire Rated Door
Product Features
Fire Resistance Performance
The core of steel glass fire rated doors relies on fire rated glass, which forms a heat-insulating glaze layer at high temperatures to block flame penetration. The steel frame enhances structural stability, and when combined with fire-resistant sealing strips, the doors achieve a balance between light transmission and fire protection.
Smoke Sealing
The door gap is precisely controlled within 1–3 mm and paired with a door closer to ensure the door remains closed. The fire-sealing strip stays flexible at normal temperatures and expands under heat to tightly seal gaps, effectively preventing the spread of toxic smoke.
Durability & Strength
Both the door frame and door leaf are made of high-quality galvanized steel sheets and fire-resistant glass, featuring excellent corrosion resistance and good light transmission. The door frame is processed through welding forming or an interlocking formed structure, enabling the steel glass fire rated door to withstand daily collisions.
Aesthetic Appearance
It supports electrostatic powder coating (colors can be selected from the RAL color chart) and wood grain heat transfer printing (simulating oak, walnut wood textures, etc.). The surface coating is free of pinholes and bubbles, and the glass has excellent light transmission performance. These features enable our steel glass fire-resistant doors to adapt to diverse styles such as modern and minimalist, integrating both lighting function and design appeal.
Installation & Maintenance
The frame is fixed with expansion bolts, and the gap between the frame and wall is filled with cement mortar for stability. Routine maintenance is simple—regularly check the hardware for flexibility, clean the sealing strips, and replace any damaged components individually—ensuring a longer service life for the steel fire-rated door.

| Surface Treatment | Electrostatic Powder Coating: A surface finishing process that uses electrostatic attraction to apply powder coating onto the steel surface, followed by high-temperature curing to form a protective and decorative layer. This technique is widely used for steel glass fire-rated doors to enhance corrosion and rust resistance, extend service life, and improve aesthetic appearance. | |
Wood Grain Heat Transfer Printing: A surface treatment process that transfers pre-printed wood grain patterns from a transfer film onto the surface of the door frame or leaf through controlled heat and pressure. It preserves the physical properties of the steel glass fire rated door’s base material while imparting the natural visual texture of real wood.
