In densely populated areas such as commercial complexes and shopping malls,fire compartmentation is a crucial measure for ensuring fire safety.However,traditional solid fire doors often negatively impact pedestrian experience due to frequent opening and closing,and are prone to failure due to human negligence in leaving them open.Glass-coated stainless steel fire doors,with their”normally closed automatic reset”function and transparent design,offer a new open solution for fire compartmentation in commercial areas,balancing safety and convenience.
Normally Closed Automatic Reset:A Balance of Safety and Convenience
Glass-coated stainless steel fire doors utilize mechanical or electric door closers,coupled with a sequencer to achieve the”normally closed automatic reset”function:
Forced Closure in Fire:The door closer has a built-in spring or hydraulic device,allowing the door to automatically close within 5-7 seconds after opening,ensuring rapid containment of fire.
Maintenance-Free Daily Use:The door closer is certified by national fire safety standards,with a durability of over 500,000 cycles,eliminating the need for frequent adjustments and reducing maintenance costs.
Anti-Stuck Design:A 3-5 second buffer period is provided before the door closes to prevent pedestrian injury.An optional electromagnetic release device is also included,allowing the fire alarm system to automatically close the door in case of fire.
Transparent Design:Open and Unconfined Space
The doors combine tempered fire-resistant glass with a 304 stainless steel frame,achieving a light transmittance of≥80%,breaking away from the closed-off feel of traditional fire doors.
Visual Continuity:In shopping mall atriums and pedestrian streets,transparent glass doors maintain visual openness,avoiding the sense of fragmentation caused by fire compartment divisions.
Optimized Natural Lighting:High-transmittance glass reduces the need for artificial lighting,lowers energy consumption,and enhances the comfort of the indoor lighting environment.
Decorative Compatibility:The stainless steel frame can be finished with brushed or mirrored surfaces,seamlessly integrating with the décor of commercial spaces.
Application Scenarios:From Public Areas to Core Corridors
Atrium Corridor:Connects fire compartments on different floors,maintaining unobstructed customer flow.
Brand Store Entrance:Separates shops from public areas,meeting fire safety regulations while enhancing store display.
Equipment Room Corridor:Protects critical facilities such as electrical rooms and air conditioning rooms;automatic closing function prevents smoke intrusion during a fire.
With”normally closed automatic reset”as its core feature,glass and stainless steel fire doors achieve”open-style safety”for fire compartments in commercial areas through technological optimization and human-centered design,providing a more efficient and comfortable solution for fire protection in modern buildings.
