Stainless Steel Fire Door Technical Requirements
Stainless steel fire resistant doors are manufactured in strict accordance with the latest national standard GB 12955-2024 Fire Doors. The products have been comprehensively optimized and upgraded to meet the new technical requirements for fire doors dedicated to facility and equipment spaces.
Under the new standard, fire doors are classified into three categories by application scenario: fire doors for evacuation routes, fire doors for facility and equipment spaces, and residential entrance fire doors. Differentiated requirements on fire resistance, airtightness and structural performance are specified for equipment room applications.
The product complies with newly added core indicators of the new standard, including smoke tightness, resistance to water jet impact and mechanical stability. During fire suppression, the door can withstand water jet impact from fire hoses without door deformation, seal failure or loss of fire resistance. It meets stringent fire protection requirements for critical fire zones in equipment rooms.
Full sets of 3C certification, test reports and factory documentation are available to ensure smooth project acceptance.
Products Description
To address irregular building opening dimensions and differentiated functional requirements across applications, we provide one-stop customized services for stainless steel fire rated doors. Custom options include single-leaf, double-leaf, transom window equipped, threshold-free, extra-large and special-shaped sizes.
Suitable for both new construction equipment room installations and fire door retrofits of existing projects. Doors are precisely fabricated according to site-measured dimensions, fire resistance ratings, installation conditions and aesthetic requirements. No on-site cutting or modification is needed, eliminating potential risks during subsequent acceptance inspections.
All custom products are manufactured in strict compliance with national standard process specifications, with qualified structural, fire resistance, airtightness and mechanical properties. The products are applicable to equipment room and passage projects in office buildings, industrial parks, manufacturing plants, hospitals, rail transit, data centers and other full-range scenarios.
