Stainless Steel Glass Fire Rated Door
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
