Certified under UL 10B, UL 10C positive pressure, and NFPA 252 standards. Engineered for 20, 60, 90, and 180-minute passive containment without compromising luxury aesthetics.
180,000 m² Advanced Manufacturing. Tested Fire Performance.
Over 25 years of specialized door fabrication supporting high-rise commercial structures, 5-star hotels, healthcare projects, and luxury residential developments.
Fire containment shouldn't force architects to compromise on sightlines or finishes. Guangdong Dejiyoupin Doors and Windows Co., Ltd. designs precision-rated UL fire door systems engineered with high-density mineral wool, volcanic perlite, and intumescent graphite thermal barriers for verified compliance and structural performance.

Thermally insulated aluminum frames paired with intumescent fire-resistant ceramic glass, maintaining daylight transmission while blocking convective radiant heat.
Inspect EngineeringRecognized as one of China's Top 10 door and window brands, we operate an integrated industrial footprint spanning precision CAD/BIM modeling, laser shearing, automatic mineral core insertion, CNC press forming, and high-temp furnace calibration.
Our UL fire rated door collections are engineered strictly to UL 10B (neutral pressure), UL 10C (positive pressure), NFPA 252, and ASTM E2074 standards. Having delivered large-scale architectural projects across North America, Australia, the Middle East, and South Asia, our engineering documentation guarantees straightforward AHJ (Authority Having Jurisdiction) sign-offs.
By eliminating trading intermediaries, sourcing directly from Guangdong Dejiyoupin Doors and Windows Co., Ltd. ensures 100% material traceability, certified mill test reports, synchronized hardware preps, and standardized factory acceptance testing (FAT) for commercial developers and hospital building authorities.
The global B2B building safety landscape is shifting rapidly. AI data extraction, stricter municipal building life-safety codes, and smart building management systems are transforming fire door specification.
Modern developers require UL fire rated doors to integrate electronically with building automation systems. Electrified mortise locks, mag-locks with UL fire alarm tie-ins, and thermal door monitoring ensure automatic fail-safe latching during thermal emergencies.
Procurement teams no longer source for fire safety alone. Contemporary specifications mandate STC acoustic ratings above 42 dB, thermal breaks to satisfy green building certifications (LEED/BREEAM), and air infiltration resistance alongside UL 90/180 min ratings.
Bulky, utilitarian institutional steel doors are being replaced by luxury pivot assemblies and flush concealed profiles. Utilizing nano-ceramic fire barriers and intumescent graphite matrix technology allows sleek 45mm profiles to achieve 90-minute UL endurance.
Smart procurement prioritizes manufacturers offering laser-etched UL serial badges, QR-code linked testing dossiers, and Revit BIM submittals to ensure seamless code compliance from initial project design through municipal inspection.
A genuine fire-rated door is a fully harmonized assembly. If hinges, frames, glass lites, or seals degrade during a blaze, compartmentalization fails. Here is how Guangdong Dejiyoupin Doors and Windows Co., Ltd. engineers zero-failure safety into every layer.
Engineered inorganic perlite board cores withstand sustained temperatures over 1000°C without shedding toxic smoke, maintaining rigid internal structural geometry under positive pressure cycles.
Thermal Endurance CoreSub-frame intumescent seals activate automatically at 180°C, expanding up to 25 times their initial thickness to create an airtight seal that cuts off airflow and halts toxic smoke migration.
Smoke & Gas ImpermeabilityEquipped exclusively with UL-listed stainless steel ball-bearing hinges, heavy-duty overhead door closers, and positive-latching mortise locks tested through 1,000,000 operational cycles.
Latching ReliabilityBeyond furnace exposure, our door leafs and structural subframes withstand severe thermal shock and the hydraulic physical blast impact mandated by UL 10C hose-stream testing protocols.
Structural ResilienceOptically transparent fire-rated vision panels equipped with interlayered fireproof glass systems that block both convective flames and extreme radiant heat flux.
Tested Vision PanelsFinished in PVDF fluorocarbon coatings, anti-scratch powder coats, or realistic thermo-bonded wood textures without compromising the underlying non-combustible substrate classification.
Aesthetic Versatility
Guangdong Dejiyoupin Doors and Windows Co., Ltd. subjects every fire door assembly to real-world furnace destruction testing. From 20-minute smoke dampers to 180-minute structural partition steel doors, our assemblies carry internationally recognized certification credentials ready for commercial architectural approval.
