Explore our primary collection of certified high-integrity fire doors, architectural wood assemblies, and high-performance safety structures engineered for multi-environment deployments.
In modern architectural design and passive fire protection (PFP) methodologies, a fire-rated door is not merely an entry block but a highly engineered, life-saving barrier. Fire door assemblies function by containing smoke, toxic fumes, and intense heat within specific compartmentalized zones. This restricts the spread of a structural blaze, maintaining clear escape pathways for occupants and protecting emergency response personnel.
Compliance with international building codes is paramount when selecting the appropriate fire door assembly. As global suppliers, Dongguan Gerald Doors Co., Ltd. develops and manufactures systems conforming to the highest industry testing protocols, ensuring compliance with strict regional and project-specific requirements:
| Standardization Code | Primary Jurisdictions | Testing Parameters / Methodology | Common Rating Ranges |
|---|---|---|---|
| UL 10B / UL 10C | North America, Middle East | Positive pressure tests, fire endurance, and the rigorous "Hose Stream Test" to verify structural durability under thermal shock. | 20, 60, 90, 180 Minutes (3 Hours) |
| BS 476 Part 22 | United Kingdom, Commonwealth, Southeast Asia | Integrity assessment evaluating the duration the assembly prevents the passage of flames and hot gases. | 30, 60, 90, 120 Minutes (FD30 - FD120) |
| EN 1634-1 / EN 13501-2 | European Union (EU), Associated Global Projects | Assessment categorized into Integrity (E) and Thermal Insulation (I). Controls thermal radiation and temperature transfer. | EI30, EI60, EI90, EI120 |
| NFPA 80 / NFPA 101 | Global Commercial Projects | Installation, testing, and maintenance standards for fire door assemblies, ensuring continuous visual inspection protocols. | Mandatory operational directives |
For high-occupancy structures such as hospitals, hotel corridors, educational facilities, and manufacturing spaces, aligning product selection with these precise certifications prevents insurance liability issues, satisfies structural codes, and protects human lives.
Every material within a certified fire door assembly contributes to fire containment. At Gerald Doors, we combine structural durability with premium finishes to deliver doors that balance aesthetic appeal with high fire resistance.
Constructed with cold-rolled steel sheet faces (1.0mm to 1.5mm thickness) and internal stiffeners. Standard insulation options include mineral rock wool cores (density > 120kg/m³), polyurethane, or honeycomb structures. This core composition limits heat transfer, ensuring the unexposed surface remains at safe temperatures during a fire.
Ideal for luxury commercial spaces, hotels, and upscale apartments. Engineered with solid mineral composite cores, high-density fiberboard (HDF) crossbands, and high-quality real wood veneers. This configuration provides up to 60-90 minutes of certified protection while maintaining a premium aesthetic.
Equipped with thermal-expansion intumescent edge strips that expand rapidly at temperatures above 150°C. This chemical reaction seals the gap between the door and frame, blocking toxic carbon monoxide and hot gases. Hardware configurations include panic exit devices, automatic closers, and heavy-duty steel hinges.
Based in China’s manufacturing hub, Dongguan Gerald Doors Co., Ltd. is a global leader in designing, testing, and manufacturing commercial, residential, and industrial doors. Our product portfolio includes industrial overhead doors, sectional doors, roller shutter doors, high-speed doors, garage doors, and certified high-integrity fire-rated assemblies.
We support international engineering partners, general contractors, and developers with custom architectural solutions that meet strict safety codes. By integrating advanced production automation with premium raw materials, we deliver reliable performance and architectural versatility.
The global commercial real estate market demands strict adherence to build quality, delivery schedules, and cost efficiency. Procuring fire-rated door assemblies directly from a certified Chinese manufacturer like Dongguan Gerald Doors Co., Ltd. offers significant advantages:
Our manufacturing facility in Dongguan utilizes advanced production techniques to deliver reliable, code-compliant door assemblies.

Different architectural designs require specific performance parameters for fire-rated doors. Our product line is engineered to meet the unique functional requirements of various sectors:
Healthcare environments require fire containment, acoustic control, and seamless accessibility. We provide UL-certified steel entry doors with integrated viewing windows, electromagnetic hold-open devices linked to building fire alarm systems, and double-swing operations to facilitate rapid patient evacuation.
Guest entry doors must balance safety codes with high-end interior aesthetics. Our collection includes fireproof wooden doors (30 to 90-minute ratings) finished with luxury wood veneers or laminates. These doors feature hidden automatic drop seals to manage smoke transfer and improve acoustic performance (STC ratings up to 45dB).
Industrial facilities require rugged, impact-resistant fire barriers. Our EI60/EI90/EI180 galvanized steel exit doors are engineered for durability. Features include heavy-duty reinforcement channels, weatherproofing seals, and integrated panic push bars to ensure reliable performance in high-traffic commercial environments.
Detailed answers to technical questions commonly raised by MEP engineers, architects, project procurement officers, and building safety inspectors.
UL 10B utilizes neutral pressure testing, where the pressure neutral plane is located at the top of the door assembly. UL 10C introduces positive pressure testing, where the neutral pressure plane is located at 40 inches above the sill, simulating the conditions of a real structural fire. Under UL 10C, hot air and gases exert pressure on the upper portion of the door, requiring the use of intumescent edge seals to prevent the escape of hot gases.
Yes, but vision lites must use certified, high-temperature borosilicate or ceramic fireproof glass (such as 4mm/5mm tempered ceramic glass options). The glass size and total area must comply with the door's fire rating. For example, a 90-minute fire-rated door has stricter limits on the maximum allowable glass area compared to a 20-minute door. All glass installations must be completed using approved fireproof steel glazing beads and ceramic gaskets.
High-density mineral rock wool (>120 kg/m³) provides superior thermal insulation and high fire resistance, making it suitable for 90-minute and 180-minute ratings. Honeycomb and polyurethane cores are lighter and provide excellent rigidity and thermal insulation for standard use, but are generally limited to 20-minute or 45-minute fire-rated assemblies.
We provide complete engineering drawings, material submittal sheets, and copies of compliance certifications for project approval. Additionally, we pre-punch locksets, hinge locations, and panic hardware channels based on specifications, ensuring hardware compatibility and reducing installation labor costs on-site.
Fire-rated door assemblies must be installed in accordance with NFPA 80 guidelines. Key requirements include maintaining specific clearances (typically 1/8 inch at the head and jambs, and 3/4 inch maximum at the bottom sill) and using only certified fire-rated hinges, latches, and automatic closers. Any field modifications not covered by the manufacturer's certification can void the fire rating.
