Explore our CE-certified architectural line engineered with multi-layered thermal barriers, acoustic damping polymers, and corrosion-resistant aluminium alloys tailored for international building compliance.
Modern building envelopes demand unprecedented structural performance, stringent fire resistance, superior thermal boundary continuity, and distinctive architectural elegance. As a Tier-1 international manufacturer and specialized OEM/ODM supplier, DERCHI (Guangdong Dejiyoupin Doors and Windows Co., Ltd.) pioneers the fabrication of CE Certified Aluminium Composite Doors. Fabricated under stringent ISO 9001 quality management benchmarks and certified compliant with harmonized European standard EN 14351-1, our door systems unify aerospace-grade 6063-T6 architectural aluminium alloys, non-combustible core matrixes, polyamide thermal isolation, and advanced surface polymers.
Standard architectural doors manufactured exclusively from timber or singular uninsulated polymers suffer chronic dimensional vulnerability in fluctuating environments. In contrast, aluminium composite technology strategically distributes mechanical stresses across multi-layered laminae. External faces feature extruded structural aluminium with electrostatically deposited fluorocarbon (PVDF) or anodic oxide finishes, creating an impenetrable shield against UV radiation, torrential driving rain, and corrosive marine salinity. Internally, multi-axis structural ribbing and bonded hexagonal honeycomb cells absorb shear vectors, achieving unrivaled torsional rigidity while significantly lowering self-weight.
Procuring fenestration and entrance assets for multi-family residential towers, luxury resort complexes, or civic installations requires meticulous verification of laboratory test figures. DERCHI composite assemblies are subjected to accredited European third-party test chambers to substantiate physical, acoustic, and thermal thresholds:
| Performance Dimension | Test Standard / Benchmark | Certified Performance Value | Architectural Engineering Benefit |
|---|---|---|---|
| Thermal Transmittance (U-Value) | EN ISO 10077-1 / EN ISO 10077-2 | 0.85 – 1.20 W/(m²·K) | Exceeds Passive House & European Energy Efficiency directives; reduces HVAC operating loads. |
| Air Permeability | EN 1026 / EN 12207 | Class 4 (600 Pa maximum test pressure) | Triple continuous EPDM/silicone gasket compression ensures zero draft infiltration. |
| Watertightness | EN 1027 / EN 12208 | Class E1050 (Severe exposure threshold) | Pressure-equalized weep drainage prevents perimeter water ingress under heavy cyclonic driving storms. |
| Wind Load Resistance | EN 12211 / EN 12210 / AS 2047 N6 | Class C5 / Cyclic ultimate limit state ≥ 3.0 kPa | Resists severe coastal typhoons and windward high-altitude atmospheric structural deflection. |
| Acoustic Attenuation (Rw / STC) | EN ISO 10140-2 / ASTM E90 | Rw = 36 dB to 44 dB | Multi-density composite core and decoupled perimeter damping attenuate high and low-frequency urban noise. |
| Fire Retardancy & Smoke Containment | EN 1634-1 / UL 10C / WH Listed | EI30, EI60, EI90, Class A Non-combustible | Meets critical building egress compliance codes with ceramic intumescent expanding seals. |
The historical trajectory of composite entrance doors has evolved from rudimentary sheet-glued polyurethanes toward structurally sophisticated, mechanically integrated composites. The contemporary market no longer accepts compromises between thermal insulation and thin structural skins. Our continuous research and development cycles have introduced three definitive technological breakthroughs to the fenestration landscape:
Utilizing high-tensile 3003-series alloy honeycomb cores with micro-apertures. This creates superior strength-to-weight ratios, eliminating surface oil-canning and delivering absolute planar flatness up to 4-meter heights.
Reinforced polyamide thermal struts with 25% glass fiber prevent thermodynamic bridging between internal and external aluminium faces, preventing internal condensation in sub-zero or humid tropical climates.
Seamlessly fusing natural architectural hardwood veneers or antibacterial CPL polymers onto internal surfaces while maintaining hardened, weatherproof fluorocarbon aluminium exteriors.
As international supply chains navigate sustainability obligations, environmental product declarations (EPD), and accelerated on-site construction schedules, commercial procurement strategies are undergoing fundamental transformations:
1. Decarbonization and Circular Recyclability: Institutional developers in the EU, North America, and Australasia now assign weighted procurement criteria to low-carbon secondary aluminium (circular scrap extrusion) and non-hazardous binder adhesives. DERCHI utilizes hydro-powered aluminium smelting profiles and volatile organic compound (VOC)-free structural polyurethanes, providing verifiable EPD documentation for projects pursuing LEED Platinum, BREEAM, or DGNB green building ratings.
2. Pre-Hung Modular Assembly & Jobsite Labor Minimization: Escalating on-site labor expenditures and regional artisan shortages have rendered field-assembled knock-down frames financially inefficient. Future-ready specifiers require pre-machined, factory-glazed, fully balanced pre-hung door systems complete with integrated sub-frames, pre-wired conduit channels for electronic access control, and self-leveling acoustic drop seals.
3. Smart Ingress Automation & Biometric Security Integration: Modern composite entrance systems increasingly integrate hidden motorization and biometric authentication directly within the multi-point locking core. Concealed magnetic reed contacts, automated electric motor strikes, 3D facial recognition cameras, and smart home IoT protocols (Zigbee, Matter, KNX) must be pre-calibrated without compromising air tightness or acoustic ratings.
4. Oversized Monumental Scale Pivot Doors: Villa architects and commercial developers are substituting conventional standard-sized swing doors with expansive architectural pivot assemblies reaching 3.5 to 5 meters in height and up to 2.2 meters in width. Engineered composite cores are indispensable for these monumental scales to resist wind loads up to AS 2047 N6 without structural bow or deflection.

Direct technical answers addressing the critical evaluation criteria required by project architects, quantity surveyors, procurement managers, and facade engineering consultants:
Our doors are tested and certified under EN 14351-1:2006+A2:2016 (Windows and doors - Product standard, performance characteristics). For fire-rated configurations, assemblies comply with EN 1634-1 fire resistance and EN 1634-3 smoke control protocols, accompanied by authentic Declaration of Performance (DoP) documents and factory production control tracking.
When exposed to intense exterior sun exposure while interior spaces remain air-conditioned, temperature differentials of up to 45°C can cause severe differential expansion. DERCHI mitigates this by utilizing patented floating composite skin anchors, split polyamide thermal break bars, and reinforced anti-distortion cores that accommodate thermal expansion without frame warping.
Yes. Our engineering division custom-fabricates entrances up to 5,000mm in panel height and 2,500mm in width. Heavy-duty pivot systems feature German/Italian German-engineered hydraulic floor springs rated up to 800kg with 3D spatial micro-adjustability, integrated hold-open dampers, and perimeter mechanical magnetic drop seals.
Upon initial receipt of door schedules and architectural drawings, DERCHI issues complete CAD shop drawings within 48 hours. Upon drawing confirmation and deposit clearance, standard manufacturing lead times range between 25 and 35 calendar days. Expedited production pipelines are available for mission-critical project fast-tracking.
