In high-rise buildings,commercial complexes,hospitals,and other locations with stringent fire safety requirements,stainless steel glass fire doors,with their dual advantages of”Class A fire resistance+high light transmittance,”have become an ideal choice that balances safety and spatial aesthetics.
Class A Fire Resistance:1.5-Hour Extreme Protection
According to national standards,Class A fire doors must prevent flame penetration for 1.5 hours,and the average temperature rise of the unexposed surface must not exceed 140℃.Stainless steel glass fire doors achieve this goal through a triple protection system of”frame insulation+fire-resistant glass+hardware locking”:
Frame insulation:Utilizing a 304 stainless steel frame,its thermal conductivity is only 1/3 that of ordinary steel.Combined with fire-resistant expansion sealing strips,it effectively blocks heat transfer.
Fire-resistant glass:The door body is embedded with composite fire-resistant glass(such as single-layer tempered glass+fire-resistant adhesive layer).When heated,the fire-resistant adhesive layer expands to form an insulation layer,blocking flame and high-temperature transmission for 30 minutes and maintaining structural integrity for 1.5 hours.
Hardware locking:Equipped with high-temperature resistant stainless steel locks and door closers,automatically closing and locking in case of fire to prevent smoke penetration.
High light transmittance design:Uncompromising spatial transparency.Traditional fire doors,due to their heavy materials,can easily create a feeling of confinement.Stainless steel glass fire doors,however,achieve”visual transparency”through large-size fire-resistant glass(light transmittance≥80%).For example,in shopping mall atriums or hotel corridors,this design maintains spatial continuity and avoids visual disruption caused by fire compartment divisions;in hospital operating rooms or ICUs,medical staff can observe the indoor situation in real time through the glass,improving emergency response efficiency.Some high-end products use ultra-clear fire-resistant glass with a light transmittance of over 90%,further optimizing lighting effects.
Application Scenarios:From Public Spaces to Special Environments
Commercial Venues:Shopping mall atriums,pedestrian streets,and other areas need to meet fire compartment requirements while maintaining a sense of openness to enhance the shopping experience;
Medical Field:Hospital corridors and examination rooms use stainless steel glass fire doors,which comply with fire safety regulations and facilitate medical staff’s observation of patient conditions;
Industrial Environments:In laboratories,data centers,and other places,the stainless steel frame is highly corrosion-resistant and can resist chemical gas corrosion,while the fire-resistant glass facilitates observation of equipment operation.
From technical parameters to practical applications,stainless steel glass fire doors,with their core characteristic of”maintaining visual transparency within the Class A fire resistance time limit,”redefine the balance standard between fire safety and spatial aesthetics.
