In large public buildings,high-end commercial venues,and industrial plants,double-leaf Grade A stainless steel glass fire-rated doors,with their combination of large dimensions and top-tier fire resistance,have become a preferred solution for fire safety and spatial design.Their double-leaf structure not only meets the needs of rapid evacuation and large equipment handling,but also,by integrating Class A fire protection standards(fire resistance≥1.5 hours)with stainless steel and glass,balances safety and visual transparency,redefining the practical value of fire doors.
The core advantage of double-leaf Grade A stainless steel glass fire-rated doors lies in their”structural adaptability and enhanced performance.”The door body utilizes a thickened 304 stainless steel frame,laser-cut and argon-arc-welded,ensuring a seamless transition between the two leafs.Their deformation resistance is 40%greater than that of single-leaf doors.The fire-resistant glass embedded in the door leaf features a composite structure:an outer layer of 6mm high-strength tempered glass provides impact resistance,a middle layer of 12mm inorganic fire-resistant intumescent layer rapidly expands at high temperatures to form an insulating barrier,and an inner layer of anti-radiation coating reduces thermal radiation transmission.In a simulated fire test,the double-leaf door’s back-to-fire surface temperature did not exceed 100°C within 1.5 hours,and the glass showed no cracking or peeling,fully complying with Class A fire protection regulations.Furthermore,the double-leaf door design supports custom sizes up to 2.4 meters in width and 3 meters in height,easily adapting to the needs of extra-large spaces such as convention centers and airport terminals.
To meet diverse application requirements,double-leaf Class A stainless steel glass fire-resistant doors continue to advance in functionality.For clean environments like hospitals and laboratories,a removable sealing strip is added to the bottom of the door frame,coupled with a dust-free installation process,effectively blocking dust and microorganisms.To meet the evacuation efficiency requirements of commercial venues,electromagnetic door closers and sequencers ensure synchronized closing of both doors in the event of a fire,preventing fire protection failure due to a single door being stuck.Some models also integrate intelligent control systems,such as automatic fire unlocking,triggering fire alarms,or using pressure sensors to monitor door closure status in real time,enhancing intelligent fire management.
From safe passage to aesthetically pleasing spaces,double-leaf Grade A stainless steel glass fire doors,with their large design and top-tier fire performance,provide a more efficient and secure solution for modern buildings.Their balance of practicality and visual aesthetics not only enhances fire safety levels,but also,through innovative materials and craftsmanship,elevates fire doors from a”functional accessory”to a”space highlight,”making them an ideal choice for fire protection design in high-end venues.
