Architectural Fire-Rated & Structural Aluminium Systems
Precision-engineered profiles built from 6063-T6/6060-T6 structural aluminium, designed to integrate seamlessly into modern façades requiring certified fire protection, high acoustic isolation, and weather resistance.
Engineering Integrity: Custom OEM Fire-Rated Aluminium Door Systems
In high-density commercial developments, hospitality projects, and modern mixed-use towers, passive fire protection must perform flawlessly without compromising architectural aesthetics. Specifying custom OEM aluminium fire doors requires balancing structural aluminium alloys, intumescent thermal breaks, ceramic fire glass, and perimeter seals under intense temperatures exceeding 1000°C. DERCHI (Guangdong Dejiyoupin Doors and Windows Co., Ltd.) operates a specialized fabrication division dedicated to building fire-rated entry assemblies, pivot systems, and commercial curtain barriers that satisfy stringent international building codes including EN 1634-1, EN 13501-2, UL 10C, and BS 476-22.
Unlike standard architectural aluminium that softens rapidly when exposed to fire, our OEM composite assemblies incorporate specialized internal fire-core materials, reinforced steel bracket armatures, and patented multi-chamber ceramic silicate cooling fills. These design enhancements limit thermal transfer, prevent structural frame deflection, and restrict smoke migration along critical escape routes.
Classifications: Integrity (E) vs Insulation (EI)
Specifiers must distinguish between Class E (Integrity) and Class EI (Integrity & Insulation). Class E prevents flames and hot toxic gases from breaching the door envelope, while Class EI incorporates fire-rated intumescent gel interlayers within laminated glazing panels to control radiant heat transfer. In European and high-tier global standards, Class EI (EI30, EI60, EI90, EI120) is essential for fire stairwells, server rooms, and luxury escape corridors, ensuring the unexposed surface remains below a safe average temperature rise of 140°C above ambient.

| Performance Attribute | Standard Reference | Achievable Range / Rating | OEM Structural Construction Detail |
|---|---|---|---|
| Fire Resistance (EI Rating) | EN 1634-1 / BS 476-22 | EI30, EI60, EI90, EI120 mins | Multi-chamber aluminium profile filled with fire-resistant ceramic paste; high-expansion intumescent seals. |
| Glazing Integrity | EN 1363-1 / ISO 834 | Laminated / Toughened Fire Glass | Multi-layer clear float glass interleaved with intumescent fire gel, turning opaque and insulating during fire events. |
| Thermal Transmittance (Ud) | EN ISO 10077-1/-2 | Ud down to 0.85 W/(m²·K) | Polyamide PA66 GF25 thermal break bar integrated with high-density polyurethane insulation cores. |
| Burglar & Intrusion Resistance | EN 1627 - RC2 / RC3 / RC4 | Up to Class RC3 / RC4 | Multi-point motorized or mechanical automatic deadbolt locking, anti-drill plates, and high-tensile alloy reinforcement. |
| Air & Water Permeability | EN 12207 / EN 12208 | Class 4 (Air) / Class 9A (Water) | Continuous EPDM vulcanized sealing gaskets paired with specialized automatic drop-down mechanical thresholds. |

Future Sourcing & Procurement Trends in Fire Doors
Architects, facade consultants, and general contractors are adapting to shifting regulatory frameworks, sustainability targets, and smart building integration.
1. Ultra-Narrow Sightlines & Flush Profiles
Bulky, industrial fire door frames are being replaced by minimalist 6000-series alloy systems. Specifiers now favor 20mm-50mm visible profiles, concealed high-capacity pivot mechanisms, and frameless fire glass that integrate cleanly into surrounding walls.
2. Embodied Carbon & Circularity (EPDs)
European developers under the EU Taxonomy, BREEAM, and LEED v4.1 frameworks increasingly require Environmental Product Declarations (EPDs). Sourcing certified recycled billets (e.g., >75% post-consumer aluminium) significantly reduces scope 3 carbon impacts.
3. BMS & Biometric Access Integration
Modern fire assemblies must interface seamlessly with Building Management Systems (BMS). Procurement specifications often mandate motorized multi-point locks that disengage during life-safety alerts while supporting encrypted RFID or biometric access for daily operation.
4. Dual Testing: Fire + Cyclone & Acoustic
Urban density and climate volatility call for multi-functional doors. Overseas projects routinely combine fire ratings (EI60) with acoustic damping (Rw 42dB) and extreme wind-load resistance (such as Australian AS 2047 N6 testing), all in one system.
5. Strict Digital Audit Trails (Golden Thread)
Following legislation like the UK Building Safety Act, project teams maintain detailed digital records for every fire door. Custom OEM manufacturers must supply traceable batch certificates, glass identification stamps, and clear component schedules for handover.
6. Turnkey Single-Source Supply Chains
Developers are moving away from piecemeal sourcing to reduce liability risks. Sourcing fire-rated entrance doors, oversized pivot entries, and matching glazed curtain walls from a single integrated factory streamlines engineering warranties and site installation.
