Precision-engineered extruded aluminum exterior systems manufactured strictly to AS 2047, CE, and ASTM specifications. Direct procurement for commercial contractors, facade specialists, and luxury residential developments.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates one of Asia's most sophisticated architectural aluminum manufacturing ecosystems. Verified by independent international testing bodies, our facility delivers end-to-end extrusion, CNC machining, fluorocarbon surface finishing, and glazed assembly under strict ISO 9001 quality governance.
Our front door systems undergo rigorous cyclic pressure and structural wind loading tests up to 4500 Pa, satisfying Australian N6 criteria, tropical cyclone parameters, and North American hurricane impact standards without frame deflection.
Utilizing high-purity virgin aluminum billet (Alloy 6063-T5/T6), our computerized extrusion and anodizing lines yield wall thicknesses between 2.0mm and 3.5mm, providing unparalleled torsion resistance for oversized pivot structures.
Every commercial inquiry receives parametric shop drawings, section details, and structural anchoring calculations from our bilingual structural engineering department, eliminating site measurement mismatches before CNC milling.
Modern architectural envelope design demands a balance between minimal sightlines and extreme structural resistance. When evaluating OEM/ODM manufacturing partners, professional specifiers review metallurgical composition, thermal bridging, and multi-point mechanical engagement.
Aluminum inherently exhibits high thermal conductivity (~205 W/m·K). In high-performance OEM manufacturing, thermal bridging is neutralized using glass-fiber reinforced polyamide strips (PA66 GF25) crimped between internal and external aluminum extrusions. This achieves U-factors as low as 1.1 W/m²·K (0.19 BTU/h·ft²·°F) when paired with argon-filled low-E insulated glass units (IGU).
Furthermore, cast aluminum facade doors incorporate aerogel insulation cores and closed-cell polyurethane backings to eliminate thermal transmission, ensuring zero condensation formation even in extreme sub-zero or high-humidity tropical climates.

Procurement departments at major international construction conglomerates, wholesale importers, and architectural firms are adapting to regulatory shifts, smart building standards, and circular economy mandates.
Architects are standardizing on monumental entry doors measuring up to 2.2m wide by 4.0m high, weighing in excess of 450 kg. Procurement trend analysis indicates high demand for invisible in-floor hydraulic pivot closers featuring integrated 24V motorized multi-point locks that sync with smart home automation, biometric readers, and facial recognition.
With cross-border carbon border adjustment mechanisms (CBAM) coming into force across Europe and strict green star credentials in Oceania, wholesale buyers are requiring certified low-carbon aluminum billets produced via renewable hydropower, accompanied by full Environmental Product Declarations (EPDs).
Project procurement directors are moving away from multi-vendor fragmentation. By procuring front pivot doors, thermal break casement windows, sliding stackers, and automatic garage roller shutters from a single tier-1 OEM exporter, developers eliminate color variance, streamline sea-freight containers, and cut overhead costs by 22-35%.
Transparent quality control protocols designed to serve international distributors, developers, and project engineers without requiring frequent overseas visits.
Our engineering division audits your window & door schedules, wind exposure data, and structural anchoring constraints.
Parametric shop drawings detailing mullion depths, glazing pocket dimensions, and threshold drainage are issued for certified sign-off.
Extrusions are processed on 5-axis German CNC machining centers, guaranteeing corner joint tolerances within 0.1mm.
100% factory trial assembly, lock alignment check, surface gloss verification, and water tightness validation prior to crating.
Fumigated solid wooden crates lined with moisture barriers, steel banding, and desiccant packs shipped direct to port.
Direct answers addressing certification, lead times, sea freight risk mitigation, and custom architectural fabrication.
Send your architectural schedules, door specifications, or project CAD drawings. Our bilingual engineers will provide detailed structural reviews, thermal performance assessments, and factory-direct pricing within 24 hours.
