Industrial Scale Meets Bespoke Architectural Precision
Recognized among the Top 10 High-End Architectural Fenestration Brands in China, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates from Foshan, the epicenter of global structural metallurgy. Over 25 years, our facility has evolved from an extrusion manufacturer into a comprehensive OEM/ODM solutions provider serving landmark developments, high-density residential towers, and ultra-luxury private villas across Europe, North America, Oceania, and the Middle East.
Our facility integrates multi-axis German CNC milling centers, robotic automatic glass-curing assembly lines, and calibrated cyclonic chamber testing facilities. By keeping structural simulation, thermal bridging calculations, powder coating, and final assembly under one quality management umbrella, DERCHI guarantees full structural traceability, dimensional tolerances within ±0.5mm, and supply chain security for tier-one international construction projects.

Engineering Capabilities Built for Institutional Tenders
Why Tier-1 architectural developers, facade contractors, and regional distributors establish exclusive OEM/ODM production partnerships with DERCHI.
Multinational Certification
Fully tested under AS2047 (N6 Cyclonic Ratings), European standard CE EN 14351-1, ISO 9001, and UL Fire Safety. Backed by matched Declaration of Performance (DoP) dossiers for local municipal building approvals.
Full-Scope OEM/ODM Customization
Comprehensive custom development across bespoke extrusion dies, specialized PA66 GF25 thermal breaks, oversized structural configurations, flush sills, concealed hinge hardware, and motorization integrations.
Complete Structural Facade Bundling
Mitigate trade coordination risk. Source architectural thermal-break casements, panoramic sliding walls, heavy-duty cast aluminum entrance pivots, and architectural curtain walls within a single shipment schedule.
Dedicated Engineering Support
In-house facade engineers provide free structural review, wind-load static calculations, and localized CAD shop drawings. Bilingual project managers bridge time zones with rapid technical turnaround.
Global Procurement Trends: What Major Buyers Prioritize
Architectural requirements are shifting toward stringent thermal performance, embodied carbon metrics, and integrated lifecycle engineering.
1. Passive House & Stringent U-Value Targets
With energy codes like Germany's GEG, UK Building Regs Part L, and California Title 24 tightening thermal budgets, overall window transmittance values ($U_w$) must consistently hit sub-0.8 to 1.2 W/(m²·K). Procurement teams are moving away from basic thermal breaks to multi-cavity polyamide insulating strips filled with aerogel or polyurethane foams, complemented by triple or quadruple low-E glazing with warm-edge composite spacers.
2. Carbon Neutrality & Circular Billets
Large-scale developers in Europe and North America increasingly demand Environmental Product Declarations (EPDs). The industry is trending toward low-carbon recycled aluminum billets processed via renewable hydropower. Suppliers that provide verifiable material origin documentation and circular life-cycle tracking gain a decisive advantage during municipal tender evaluations.
3. Structural Consolidation & Panoramic Openings
High-end residential design demands maximum glazing ratios with minimal visible frame profiles. Floor-to-ceiling multi-track sliding panels exceeding 600 kg require heavy-duty stainless steel rollers, recessed perimeter frames, and integrated threshold drainage systems capable of handling 50-year storm events without perimeter seal failure.
| Performance Dimension | Standard Market Profile | DERCHI Architectural Specification | Procurement Impact |
|---|---|---|---|
| Alloy Metallurgy | Recycled scrap mixed aluminum | Virgin 6063-T6 or 6060 high-tensile billets | Guarantees surface finish depth, structural wind resistance, zero micro-cracking |
| Thermal Barrier | 14.8mm PVC or standard PA66 | 24mm - 34mm PA66 GF25 reinforced technopolymer | Prevents condensation, lowers cooling/heating loads by up to 38% |
| Glazing Architecture | Standard double float insulated (5+9A+5) | Triple laminated Low-E filled with 90%+ Argon gas | Acoustic attenuation up to 45dB; complies with strict passive solar standards |
| Surface Treatment | Ordinary commercial powder coating (40μm) | Qualicoat Class 2 Fluorocarbon (PVDF) / AkzoNobel (60-80μm) | Resists UV degradation and saltwater salt-spray pitting for over 20 years |
Future Trends: Next-Gen Fenestration Engineering
DERCHI invests 8% of annual revenue into structural innovation, material science, and automation.
BIPV & Power Generation Glazing
Integrating semi-transparent cadmium telluride (CdTe) and perovskite photovoltaic cells directly into architectural curtain walls and spandrel glass, turning exterior envelopes into distributed green power units without compromising visible light transmission.
Smart-Home Facade Automation
Direct integration of brushless low-voltage magnetic levitation drives with automated building management systems (KNX, Zigbee, BACnet). Includes automated rain and wind sensors, indoor air-quality purge controls, and biometric authorization modules.
Vacuum Insulated Glazing (VIG)
Replacing thick, heavy triple-pane units with ultra-thin vacuum glazing. Achieves center-of-glass thermal performance down to U_g 0.4 W/(m²·K) at a fraction of the weight, reducing structural load while simplifying profile depths.
