In high-rise buildings,commercial complexes and public places,stainless steel glass fire doors have become an important innovation in the field of fire safety due to their high strength,corrosion resistance and strong permeability.As a fire protection solution that combines functionality and aesthetics,it has redefined the application boundaries of fire doors through material upgrades and process optimization.
Excellent fire protection performance,guarding life passages
Stainless steel glass fire doors use 304 or 316L stainless steel profiles,with a door frame thickness of 1.5mm,and a built-in galvanized square tube reinforcement for the door leaf frame,which increases the impact strength by 40%.The door leaf is filled with high-density expanded perlite board and matched with Class A heat-insulating fireproof glass(fire resistance integrity≥1.5 hours),which can maintain structural stability at high temperatures of 1000℃and effectively prevent the spread of fire.After a hospital project adopted this product,after third-party testing,the temperature of the back-fire surface of the door leaf in the fire simulation did not exceed 140℃,and the smoke transmittance was only 0.01%,far exceeding the national standard.
Aesthetic design,integrated into architectural language
Traditional fire doors often affect the beauty of buildings due to their heavy appearance,while stainless steel glass fire doors achieve diverse visual effects through surface treatment technology.More than 10 kinds of brushed or mirror effects such as titanium,rose gold,and black titanium can be seamlessly connected with modern minimalist,industrial style and other architectural styles.The glass of the door leaf accounts for 30%-50%,and the light transmittance exceeds 85%,which meets the high lighting requirements of shopping malls,office buildings,etc.For example,a high-end shopping center uses curved glass fire doors,which not only enhances the sense of space transparency,but also ensures safety through the tempering of fireproof glass.
Intelligent integration improves safety efficiency
In order to cope with complex fire scenes,the manufacturer launched an intelligent fire door system:the door frame has built-in temperature sensors and smoke detectors,which automatically trigger the door closer and link the fire protection system when the environment is abnormal;the fire handle is made of high-temperature resistant alloy material and can withstand 800℃high temperature;the door closer is equipped with a hydraulic damping device to ensure that there is no impact sound when the door leaf is closed.After a data center project adopted this system,it achieved a rapid response in the early stage of the fire,which bought precious time for the evacuation of personnel.
In the future,stainless steel glass fire doors will be iterated towards the direction of”low carbonization and intelligence”.Through the integration of photovoltaic glass and energy storage modules,the door body will be self-powered,providing a more efficient and environmentally friendly solution for smart building fire protection.
