In building fire protection engineering,Class A steel fire doors,as the highest fire-resistant protection,must meet a fire resistance limit of at least 1.5 hours.They are widely used in crowded or high-value locations such as hospitals,shopping malls,and data centers.Unlike standardized products,custom-made Class A steel fire doors can be precisely designed based on the building structure,usage scenario,and fire regulations.From material selection and sizing to functional integration,they fully meet individual needs and provide tailored solutions for fire safety.
The core advantage of custom-made Class A steel fire doors lies in performance customization and structural optimization.The door body is constructed of thickened cold-rolled steel(typically≥1.2mm)that undergoes CNC bending and laser welding to ensure a seamless connection between the door frame and door panel,increasing impact resistance by 30%.The internal filling,made of modified perlite or inorganic fiberboard,offers uniform density and low thermal conductivity,effectively blocking high temperatures.For example,a custom-made Class A fire-resistant door for a high-rise office building,by increasing the door leaf thickness to 55mm and optimizing the sealing structure of the fireproof rubber strips,achieved a 1.5-hour non-fire surface temperature of no more than 140°C,far exceeding national standards,in a simulated fire test.Furthermore,the custom service supports non-standard dimensions.Whether it’s a special-shaped door opening,an oversized door body,or a built-in installation,precise adaptation can be achieved through 3D modeling and structural mechanics analysis.
To meet diverse application requirements,custom-made Class A steel fire-resistant doors continue to innovate in functionality.For clean areas such as hospital operating rooms and laboratories,custom stainless steel doors with a brushed finish are available,offering corrosion resistance and easy cleaning.For locations requiring moisture protection,such as data centers and archives,waterproof grooves are added to the bottom of the door frame and silicone sealant is used to prevent moisture penetration.Furthermore,some custom-made products integrate intelligent modules,such as electromagnetic trip devices(interconnected with the fire protection system)and temperature-sensing automatic door closers,which automatically close the door in the event of a fire and provide status feedback to the monitoring platform.The custom-made door manufacturer also provides a full-process service,from on-site measurement and drawing development to installation and commissioning,ensuring that every door meets fire inspection requirements.
From simple protection to intelligent fire protection,custom-made Class A steel fire doors are driving safety standards through personalized design.Their precise adaptability not only solves fire protection challenges in non-standard buildings,but also,through customized materials and functions,provides more efficient and reliable fire protection for diverse scenarios.
