In large commercial complexes and shopping malls,fire compartmentation is a core measure to ensure fire safety.However,traditional solid fire doors,due to their heavy and enclosed nature,often disrupt the visual continuity and passage experience of commercial spaces.Stainless steel glass fire doors,with their dual advantages of”fire resistance+transparent design,”have become a new open solution for fire compartmentation in commercial passageways.
Fire Resistance:Class A Standard,Worry-Free Safety
Stainless steel glass fire doors strictly adhere to national fire safety regulations,employing a sealed combination of tempered fire-resistant glass and a stainless steel frame to achieve Class A fire door standards.Their core fire protection mechanism is as follows:
Glass Fire Resistance:The door body is embedded with a single layer of tempered fire-resistant glass(thickness≥12mm),with an internal composite fire-resistant adhesive layer.When heated,this expands to form a heat insulation layer,blocking flame and high-temperature transmission for 1.5 hours.The temperature of the unexposed surface does not exceed 140℃,ensuring the safety of evacuation routes during a fire.
Frame Insulation:The 304 stainless steel frame has low thermal conductivity.Combined with internally filled fire-resistant expansion sealing strips,it expands 3-5 times its original volume when heated,filling gaps and effectively blocking smoke penetration.
Automatic Closure:Equipped with fire-resistant door closers and sequential closers,the door automatically closes and locks in case of fire,preventing the spread of fire to adjacent areas.
Open Design:Enhanced Spatial Transparency and Experience**Traditional fire doors,due to their heavy materials,can create a sense of oppression in commercial spaces.Stainless steel glass fire doors,however,achieve”visual transparency”through large-size fire-resistant glass(light transmittance≥80%),maintaining a sense of openness in passageways.For example,in shopping mall atriums,pedestrian streets,or brand corridors,this design avoids visual disruption caused by fire compartment divisions,improving the customer shopping experience.In hotel lobbies or office building lobbies,the transparent fire doors blend seamlessly with the overall decoration style,meeting fire safety requirements while showcasing the quality of the space.
Application Scenarios:From Public Areas to Special Venues
Commercial Complexes:Atriums,pedestrian streets,and brand corridors require fire compartmentation while maintaining unobstructed passenger flow.
Transportation Hubs:Stainless steel glass fire doors are used in airport and subway station passageways and equipment rooms,balancing fire protection and traffic efficiency.
Medical Facilities:Hospital corridors and examination rooms are partitioned to facilitate medical staff’s observation of patients and improve emergency response speed.
From safety protection to space optimization,stainless steel glass fire doors,with their innovative”fireproof yet not enclosed”concept,redefine the solution for fire compartmentation in commercial passageways,becoming a balanced choice between fire safety and spatial aesthetics in modern architecture.
