Stainless Steel Glass Fire Rated Door - High-Quality Solution from China Suppliers and Factory
Product Features
Fire Resistance Performance
The door leaf is filled with our self-developed fire-resistant core material, while an intumescent fire-sealing strip between the door frame and the leaf expands under high temperatures to block flame penetration. This structure ensures the steel fire-rated door maintains its thermal insulation performance and meets fire resistance requirements across all rating levels.
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
Constructed from high-grade 304 stainless steel, both the frame and door leaf offer superior corrosion and wear resistance, standing up to humidity, heat, and harsh environments. The reinforced door structure provides excellent impact resistance and long-term stability — resisting deformation or cracking without frequent maintenance — ensuring durability and safety over years of use.
Aesthetic Appearance
It retains metallic properties while conveying natural textures, and can even be customized with special tones (such as bronze, black plating) according to requirements, breaking the single tone of traditional stainless steel and creating an echo or contrast with the main color of the space. The glass has excellent light-gathering performance, enabling our stainless steel glass fire-resistant doors to fit diverse styles such as modern and minimalist, and integrate both lighting function and design sense.
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.
Fire Rating

Frequently Asked Questions
Q: What is the fire resistance performance of these doors?
Our doors feature a self-developed fire-resistant core material and intumescent fire-sealing strips that expand under high temperatures. This design prevents flame penetration and maintains thermal insulation across various rating levels (Grade A, B, C, and others).
Q: How do the doors prevent smoke transmission?
The door gaps are precisely controlled within 1–3 mm and paired with automatic door closers. Additionally, the fire-sealing strips expand under heat to tightly block any gaps, effectively preventing toxic smoke from spreading.
Q: What materials are used to construct these fire-rated doors?
Both the frame and door leaf are made from high-grade 304 stainless steel, which offers exceptional wear and corrosion resistance. The core is filled with a specialized fire-resistant insulating material.
Q: Can the appearance of the stainless steel doors be customized?
Yes, the doors can be customized with special tones such as bronze or black plating to match the design of your space. They combine metallic durability with aesthetic glass integration for a modern, minimalist look.
Q: How are these doors installed and maintained?
The door frame is secured with expansion bolts and the gap is filled with cement mortar. Maintenance is straightforward: periodically inspect hardware flexibility, clean the sealing strips, and replace components individually if necessary.
Q: Where are these fire-rated doors typically used?
They are suitable for various sectors including industrial facilities, public institutions (hospitals and schools), commercial spaces (offices, hotels, residences), transportation hubs (airports and rail stations), and military or security complexes.
