Headquartered in Foshan, Guangdong—the world’s premier architectural aluminum processing capital—Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates as a globally ranked fenestration specialist with over 25 years of engineering precision. Our integrated facility spans over 180,000 square meters of automated fabrication workshops, robotic extrusion processing lines, and certified quality-testing laboratories.
From custom curtain walls, slim-frame casement windows, and oversized hurricane-proof sliding systems to architectural entry doors, our comprehensive product portfolio provides end-to-end reliability for real estate developers, structural contractors, civil engineers, and overseas fenestration distributors.
Procuring architectural glazed windows from China requires an analytical evaluation of profile metallurgy, polyamide thermal barriers, insulated glass unit (IGU) gas retention, and dynamic air-water structural infiltration ratings.
We utilize primary A00 aluminium ingots extruded to wall thicknesses of 1.4mm to 2.0mm for residential windows, and 2.0mm to 3.0mm for high-span sliding systems. T6 artificial aging enhances yield strength beyond 170 MPa, resisting extreme positive and negative typhoon gusts without permanent frame deflection.
Cheap PVC or low-grade polyamide strips crack under solar thermal stress. We strictly specify technoform polyamide PA66 reinforced with 25% glass fiber. This guarantees coefficient matching with aluminum expansion, eliminating linear shear failure while dropping overall assembly Uw values down to 1.1 - 1.4 W/m²·K.
Our dual- and triple-glazed units integrate double-silver (Low-E2) or triple-silver (Low-E3) soft vacuum magnetron sputter coatings. Filled with 90%+ Argon gas and sealed with dual-barrier polyisobutylene (PIB) plus structural silicone, they prevent condensation while filtering 99% of damaging UV rays.

How international developers, architects, and volume importers are shifting their procurement strategies to balance sustainability, speed-to-market, and supply chain transparency.
Global green building rating schemes (LEED, BREEAM, Green Star) now audit embodied carbon in fenestration. Procurement tenders increasingly demand Environmental Product Declarations (EPDs) and recycled scrap content in billet extrusion, rewarding factories with hydro-powered metallurgical supply chains.
Due to surging on-site construction labor costs in North America, Australia, and Europe, buyers are shifting from knock-down (KD) field assembly to pre-glazed, factory-calibrated unitized window cassettes with pre-fitted sub-sills and flashing fins, drastically shortening erection cycles.
Modern procurement bypasses manual 2D CAD handoffs. Specifiers mandate BIM (Building Information Modeling) objects at LOD300 or LOD400. Automated CNC five-axis milling centers directly ingest schedule coordinates, slashing production lead-times and eliminating on-site dimensional misfits.
Next-generation thermal, mechanical, and smart automation technologies engineered into modern architectural aluminum systems.
Replacing bulky triple glazing with ultra-thin (8-10mm) vacuum insulated panels. Featuring micro-spacer arrays with internal pressure lower than 0.1 Pa, VIG achieves center-of-glass Ug values of 0.4 W/m²·K while maintaining slim profile depths suitable for minimalist sightline windows.
Window frames now seamlessly host 24V brushless DC linear actuators, magnetic contact sensors, and motorized perimeter multipoint gearboxes. Connected through KNX, Zigbee, or BACnet protocols, windows auto-cycle for night purge cooling and close instantaneously upon rain-sensor detection.
To resist 3,000+ hours of coastal neutral salt spray (ASTM B117), our factory applies fluorocarbon 3-coat/2-bake PVDF and Qualicoat Class 3 super-durable powder coatings, providing 20- to 30-year resistance against severe chalking, UV degradation, and maritime humidity corrosion.
