Explore our primary portfolio of thermal-break aluminum and wood-clad fenestration systems manufactured in Foshan, China. Tested to CE, AAMA, AS2047, and ISO 9001 quality frameworks.
In high-end architectural envelope design, standard monolithic materials inevitably present compromises: all-aluminum profiles offer unmatched structural rigidity and weather endurance but suffer from severe thermal conductivity, while solid timber provides organic beauty and natural insulative warmth but remains prone to cyclical hygroscopic warping, UV bleaching, and microbiological deterioration. As a pioneer China Aluminum Wood Door Manufacturer & Exporter, our manufacturing philosophy unites these complementary elements via decoupled composite engineering.
The system relies on an exterior structural skeleton extruded from prime 6063-T6 or 6060-T66 virgin aluminum alloy, shielded by fluorocarbon PVDF or architectural-grade 25-micron anodization, bonded mechanically to a furniture-grade, kiln-dried solid timber interior core (FAS White Oak, European Larch, Burmese Teak, or American Black Walnut). Critical to the long-term integrity of the door is the floating clip-connection matrix: because aluminum has a thermal expansion coefficient of roughly 23 × 10⁻⁶ /K whereas natural wood expands tangentially across grain fibers at wildly divergent rates, direct mechanical adhesion results in internal shearing stress. Our German-patented sliding clip fasteners accommodate differential thermal kinetic expansion across temperature fluctuations from -35°C to +75°C without warping, buckling, or joint compromise.
Thermal Bridging accounts for up to 38% of residential heating and cooling energy loss through conventional fenestration. Our composite door frames incorporate structural polyamide insulation struts reinforced with 25% transverse glass fiber (Technoform PA66-GF25). These multi-chambered thermal barriers physically isolate the external aluminum weather shield from the interior timber casing, pushing frame thermal conductivity down to Uf ≤ 1.1 W/m²·K.
Combined with continuous vulcanized triple-lip EPDM weatherstripping gaskets and silicone-injected vulcanized corner vulcanizations, the system establishes an airtight, hydrostatic envelope capable of stopping driving monsoon precipitation up to 1050 Pa while achieving laboratory sound attenuation indices of STC 42 to 48 dB against intrusive urban frequency pollution.
Rigorous performance benchmarking against commercial fenestration benchmarks in accordance with EN 14351-1, ASTM E283/E331, and AS 2047 protocols.

Our factory configures four core architectural systems tuned to distinct climate profiles, spanning tropical coastal humidity, desert solar radiation, and sub-zero continental freezes.
Engineered for seamless indoor-outdoor architectural transitions in luxury villas and penthouses. Utilizes German Siegenia or Hautau lift-and-slide hardware carriages capable of elevating and translating panels up to 450 kg with fingertip effort.
The premier choice for grand residential facades. Built with internal reinforced steel stabilizing bars, dual thermal-break aluminum chassis, and heavy-duty concealed floor spring mechanisms carrying up to 600 kg.
Dual-function perimeter compression doors featuring multi-point locking cams that pull the sash hermetically into the frame upon latching. Ideal for cold climates requiring ultra-tight building envelope certification.
Strategic fenestration sourcing is evolving beyond aesthetic choice. Developers, general contractors, and tier-1 procurement agencies are adjusting criteria under tightening climate policies, carbon taxes, and architectural shifts.
International developers under LEED v4.1 and BREEAM certifications demand Environmental Product Declarations (EPDs). Sourcing certified sustainable lumber (FSC/PEFC) fused with low-carbon hydro-smelted aluminum profiles lowers structural Scope 3 carbon expenditure by up to 42% compared to synthetic PVC alternatives.
The modern luxury residential market is prioritizing floor-to-ceiling glass expanses exceeding 3.5 meters in unbraced height. Procurement specifications demand higher structural moment of inertia (Ix value) in outer aluminum flanges while maintaining visible interlock mullions under 35mm.
Mechanical keyways are rapidly becoming secondary. Modern entry portals require integrated European multipoint motorized gearboxes (GU Secury Automatic, KFV Genius) that link seamlessly with Crestron, Control4, and KNX smart building management automation platforms.
With intensified tropical typhoon seasons and coastal salinity threats, procurement bids specify cyclone testing compliance (AS/NZS 2047 N6, Florida Miami-Dade NOA hurricane impact approvals) and marine-grade fluorocarbon C5-M anti-corrosion classifications.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates one of China's most sophisticated architectural envelope manufacturing clusters in Shishan, Foshan, spanning 180,000 square meters.
Precision woodworking for aluminum-wood doors requires rigorous humidity stabilization. Imported timber logs undergo 35-day computer-controlled vacuum drying to bring internal equilibrium moisture content precisely down to 8%–12%, matching the interior climatization standards of target export zones and eliminating latent shrinkage or seasonal cracking.
The internal timber sections are milled on high-speed German 5-axis CNC machining centers (Weinig and Homag) utilizing mortise-and-tenon and dowel bonding, coated with eco-friendly German Remmers waterborne wood preservative primers and microporous elastic polyurethane topcoats that let the wood breathe while repelling internal moisture and condensation.
Our 35+ on-staff facade engineers produce parametric Revit / BIM models, structural wind deflection calculations, and comprehensive CAD shop drawings within 48 hours for architectural submittals and tender approval.
Products are backed by accredited physical laboratory test certifications including CE EN 14351-1, ISO 9001 quality management, AS 2047 N6 Australian cyclonic wind ratings, and UL fire resistance certification.
Every shipment is enclosed in multi-layer shockproof PE foam, heavy corrugated edge guards, and custom non-fumigation reinforced plywood crates with industrial desiccant packs to prevent transit damage and moisture buildup during long sea voyages.
