Engineered for high structural stability, acoustic dampening, and extreme weather resilience. Directly fabricated to custom architectural openings.
Recognised consistently among the Top 10 architectural fenestration and door manufacturing enterprises in China, Guangdong Dejiyoupin Doors and Windows Co., Ltd. represents the peak of industrial-grade entrance engineering. Headquartered in Shenke Chuangzhi Park, Shishan Town, Nanhai District, Foshan, our modern facility spans over 180,000 square meters of vertically integrated fabrication infrastructure. We serve large-scale international real estate developers, commercial contractors, and facade consultants across North America, Europe, Australia, and emerging luxury developments throughout Africa and the Middle East.
Our OEM and ODM custom engineering framework is calibrated to resolve complex architectural challenges. By operating computer numerical control (CNC) automated 5-axis extrusion centers, automated multi-point corner crimping systems, and dust-free robotic paint application tracks, we achieve microscopic tolerances under ±0.5 mm across oversized pivot doors, floor-to-ceiling entry assemblies, and high-performance bifold facades. Whether fulfilling baseline structural engineering requirements for cyclone-prone coastlines or optimizing multi-chamber profiles for net-zero passive buildings, DERCHI provides an integrated manufacturing route directly from raw virgin 6063-T5 aluminum billet extrusion to seaworthy crate delivery.
Validated by accredited third-party laboratories holding CE (EN 14351-1), ISO 9001:2015, Australian AS2047 cyclonic pressure ratings (N6 criteria), NFRC thermal standards, and UL 10C fire resistance ratings.
Full-scale shop drawing generation in CAD/Revit BIM environments. Complete tailor-made flexibility for door leaves exceeding 6 meters in height, cast aluminum 3D reliefs, and integrated fixed sidelight transoms.
Every custom entrance door undergoes individual multi-layer protective packaging: PE shrink film wrapping, heavy-duty cellular honeycomb board protection, corner guards, and fully fumigated solid wooden crates.
Specifying custom OEM aluminium entrance doors requires an in-depth understanding of metallurgy, mechanical load dissipation, and surface boundary interactions. Generic commercial doors often underperform due to inconsistent wall thickness, poor thermal barrier integration, or inferior alloy chemistry. At DERCHI, entrance door architecture is treated with the rigor of structural curtain wall engineering.
We strictly utilize primary, virgin A00-grade aluminum billets, extruding into 6063-T5 or 6063-T6 alloys configured with specific tensile strengths (≥205 MPa) and yield points (≥170 MPa). For oversized exterior pivot main doors and hurricane-resistant sliding panels, our profile wall thicknesses range from 2.0 mm to 3.5 mm—far exceeding standard residential thresholds of 1.4 mm. This enhanced moment of inertia eliminates structural deflection under high wind loads up to 4,500 Pa (equivalent to Category 5 cyclonic environments under AS4055 and ASTM E330 testing protocols).
To mitigate the naturally high thermal conductivity of aluminum (approx. 205 W/m·K), our systems incorporate multi-chamber PA66 GF25 thermal break strips (polyamide reinforced with 25% glass fiber). Unlike cheap PVC alternatives, PA66 GF25 matches the linear thermal expansion coefficient of aluminum (2.3 × 10-5 /K), preventing frame delamination under extreme thermal cycling ranging from -30°C in Nordic winters to +55°C in Middle Eastern and African summers. Combined with triple-glazed argon-filled Low-E insulated glass units (IGU), our assemblies achieve overall system U-values as low as 1.1 to 1.4 W/m²·K.

Coastal and urban environments present airborne saline and sulfur contaminants that induce filiform corrosion. Our OEM facility applies automated vertical electrostatic powder coatings and AkzoNobel fluorocarbon (PVDF / 70% Kynar 500) surface conversions adhering to AAMA 2605 requirements. Certified to withstand over 3,000 hours of continuous neutral salt spray (NSS) testing (ASTM B117), our exterior aluminum finishes offer complete UV fading resistance, ensuring decades of architectural brilliance without chalking or surface blistering.
The global facade and fenestration procurement landscape is undergoing structural evolution. Developers, general contractors, and facade consultants are systematically abandoning multi-tier distributor models in favor of direct engagement with accredited manufacturing origins. Five primary macro trends dictate modern entrance door procurement strategies:
Procurement teams no longer rely on paper submittals. Modern supply chains demand direct algorithmic transfer of architectural models via Revit and IFC data into factory-floor CNC machining files, eliminating manual measurement translation errors.
Developers reduce port handling and forwarding overhead by pairing main entry doors, bifold patio systems, acoustic casement windows, and cast aluminum perimeter gates into single consolidated factory sea containers.
Commercial developers targeting LEED, BREEAM, or Green Star status prioritize suppliers using sustainably refined, hydroelectricity-smelted aluminum profiles accompanied by verified Environmental Product Declarations (EPD).
The contemporary entrance door is no longer merely an access point; it has become a central technological showpiece integrating mechanical sophistication, spatial grandeur, and smart security. When consulting with architects, DERCHI incorporates several breakthrough architectural vectors:
Architectural trends favor colossal entrance apertures exceeding 3,000 mm in height and 2,000 mm in width. Traditional butt hinges fail under these cantilevered loads. DERCHI utilizes concealed, bottom-pivot hydraulic mechanisms engineered from high-grade German stainless steel capable of supporting single leaf weights up to 800 kg. Features include continuous 360-degree rotation damping, hold-open positions at 90 degrees, adjustable closing velocity, and integrated soft-closing deceleration that prevents frame shock waves.
Mechanical keys are rapidly becoming obsolete in modern commercial and luxury villa installations. Our OEM aluminum doors are manufactured with pre-milled, concealed wiring conduits and reinforced mortise pockets to receive smart locksets. Options include biometric fingerprint scanners flush-mounted into architectural pull handles, facial recognition cameras, motorized multi-point deadbolts, and PoE (Power over Ethernet) modules supporting BACnet or dry-contact automation loops for centralized security stations.
For high-end residential estates, modern minimalist design intersects with classical sculpture. By combining CNC engraved solid aluminum plates and one-piece cast aluminum slabs with thicknesses up to 10 mm, we create textured relief entries offering bullet-resistant and forced-entry deterrence without the rotting, swelling, or seasonal twisting inherent to solid timber main gates.
To assist international procurement managers, architects, and quantity surveyors, we have compiled comprehensive technical clarifications regarding our OEM aluminum main door manufacturing operations.
