Manufactured in strictly audited ISO 9001 certified production lines, our structural systems harmonize heavy-duty thermodynamic insulation, hurricane impact integrity, and acoustic mitigation.
As Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI), operating from China's primary industrial fenestration hub in Foshan, we bridge bespoke architectural vision and automated industrial mass production.
In the commercial architecture and luxury estate procurement landscape, precision engineering is paramount. A millimeter variance in a curtain wall transom or an entrance aperture can cascade into massive on-site downtime and budget overrun. Backed by 25+ years of dedicated structural fenestration expertise, an intelligent 180,000 m² modern manufacturing infrastructure, and an annual delivery capacity exceeding 1,000,000 m², our OEM/ODM custom operations adhere to comprehensive 360° Quality Control inspections from raw billet extrusion evaluation through to sea-freight reinforced packaging.
Including our patented Four-Side Six-Point Anti-Theft locking mechanism, delivering unmatched burglar resistance and structural air-tightness against high wind loads.
Every door profile is certified to meet or exceed rigorous international codes: CE (EU), NFRC & Energy Star (USA), AS2047 (Australia), CSA (Canada), and ISO 9001 systems.
Spearheaded by an elite team of 30+ senior fenestration structural engineers, our CAD/BIM modeling department optimizes custom extrusions, thermal barriers, and drainage acoustics.
Exporting to over 80 territories across the Middle East (UAE, KSA, Qatar), North America, Europe, and Australasia with integrated sea-freight crating and remote engineering installation support.

The global building envelope paradigm is shifting rapidly. Architectural trends demand wider uninterrupted apertures, net-zero lifecycle operational metrics, and accelerated construction cycles.
Procurement teams are facing stricter Scope 3 emissions reporting across North America, the GCC, and Europe. Modern specifications increasingly mandate low-carbon hydro-powered aluminium billets with high post-consumer scrap content, requiring OEM exporters to present validated Environmental Product Declarations (EPDs) without sacrificing alloy structural tensile resilience.
Regulatory pressures such as ASHRAE 90.1, the EU Energy Performance of Buildings Directive, and GCC Estidama / Mostadam systems have rendered uninsulated aluminium frames obsolete. Future sourcing prioritizes widened 34mm+ PA66 fiberglass polyamide breaks and triple-glazed krypton/argon fills to achieve overall whole-system U-values below 0.22 BTU/(h·ft²·°F) [1.2 W/m²K].
Hospitality masterplanners and luxury private villa developers require frameless floor-to-ceiling sliding panoramas up to 4.5 meters in height. These designs require concealed sub-head frames, motorized mechanical drive shafts, and high-tensile concealed roller bearings capable of effortlessly carrying structural glass payloads surpassing 500 kilograms per operable leaf.
Due to escalating global extreme weather events, fenestration specs mandate dynamic testing against hurricane debris impacts, rapid cycle cyclonic winds, and sandstorm particulate infiltration. EPDM co-extruded continuous vulcanized weatherstrips and engineered stainless-steel concealed drains are becoming baseline procurement demands.
OEM aluminium door production now intersects directly with Low-Voltage architectural trades. Integrated concealed magnetic contacts, biometrics, motorized multi-point locks, and real-time Building Management System (BMS) sensors are prefabricated in-factory to ensure rapid on-site plug-and-play installation.
Overseas contractors now manage supply-chain risk through high-fidelity Revit/BIM family integrations, laser tracker dimensional checking, and cloud-monitored factory acceptance tests (FAT). This transparency guarantees dimensional compatibility long before containers arrive at regional ports.
From architectural blueprint takeoff to on-site assembly guidance, our cross-functional engineering framework protects your project lifecycle.
Comprehensive audit of structural drawings, window schedules, and environmental wind/thermal loads.
Die design, profile structural modeling, and thermal break engineering optimized for regional project parameters.
Exhaustive submittal package featuring static load calculations, U-factor modeling, and exact hardware specs.
