Our OEM/ODM manufacturing facility integrates heavy-duty 6063-T5 aluminum extrusions, polyamide technoform thermal barriers (PA66GF25), and robotic insulating glass line technology to deliver commercial, institutional, and luxury residential fenestration assemblies.
Operating as a Top 10 Door and Window brand from our intelligent manufacturing hub in Foshan, Guangdong, we bridge the gap between architectural vision and industrial fabrication for prestigious developments across North America, Europe, Australia, and Southeast Asia.
Unlike regional window fabricators who assemble piecemeal third-party components, Guangdong Dejiyoupin (DERCHI) operates a vertically integrated production infrastructure. From custom tooling of proprietary extrusion dies to automated insertion of glass fiber reinforced polyamide thermal barriers, we maintain micron-level tolerance management.
Every commercial façade unit, custom glazed window, and architectural entry door system is fully pre-assembled, squared, and pressure-tested inside our facility prior to export crating. This eliminates jobsite dimensional drift and guarantees that field installation aligns perfectly with project BIM and CAD rough-opening schedules.
Our in-house technical department collaborates directly with client structural consultants, translating architectural schedules into millimeter-precise shop submittals, anchor calculations, wind load structural reports, and thermal modeling.
Engineered to conquer the planet's harshest microclimates. Our fenestration envelopes have achieved Australia's highest AS 2047 N6 rating for extreme wind loads, severe cyclic pressure, and uncompromising water penetration resistance.
Reinforced non-fumigation plywood crates with internal moisture-wicking desiccant, shock-absorbent corner dampers, and labeled lifting points ensure containerized freight reaches job sites in the US, Canada, Australia, and the Middle East in pristine condition.
A rigorous breakdown of physical properties across primary aluminum glazed fenestration typologies. All test values benchmarked against ASTM, NAFS, and AS 2047 international façade protocols.

Get CatalogThe convergence of strict municipal energy mandates, architectural minimalism, and supply chain rationalization has radically disrupted the window and curtain wall procurement market. Commercial developers and high-end residential builders must navigate key strategic paradigms.
With North American Title 24, IECC 2024, and European EPBD mandates slashing allowable U-values across building envelopes, traditional non-broken aluminum profiles have become obsolete for exterior applications. The future procurement focus is anchored on multi-chamber polyamide thermal breaks (PA66GF25) exceeding 24mm to 34mm in depth.
Coupled with triple-glazed IGUs filled with 90%+ Argon gas and warm-edge structural polymer spacers (such as Technoform or Swisspacer), modern aluminum glazed windows achieve whole-window U-factors below 0.18 BTU/hr·ft²·°F (1.0 W/m²K), matching Passivhaus operational thresholds without sacrificing structural rigidity.
Architectural demand has decisively moved toward dematerialized sightlines: interlock profiles under 20mm, totally concealed sash frames, and frameless flush threshold designs. Achieving this aesthetic while maintaining structural load-bearing capacity against Category 5 typhoon or hurricane forces requires high-strength metallurgy.
Our OEM manufacturing integrates 6063-T6 and 6061-T6 structural aluminum billets with advanced structural silicone glazing (SSG). Glass ceases to be merely infill; it becomes an active structural diaphragm resisting positive and negative wind loads, allowing ceiling-to-floor expanses up to 4.5 meters in height.
Institutional developers, REITs, and Tier-1 general contractors are increasingly held to strict ESG criteria. The embedded carbon footprint of building materials is under immense regulatory scrutiny. Virgin aluminum smelting is energy-intensive; therefore, procurement contracts demand certified low-carbon billets.
Guangdong Dejiyoupin integrates certified low-carbon recycled aluminum (utilizing renewable hydroelectric smelting) yielding carbon footprints below 4.0 kg CO2e per kg of aluminum extruded, supported by full Environmental Product Declarations (EPD) to secure LEED Platinum and BREEAM Outstanding credits.
Contractors cannot afford delivery delays or discrepancy between architectural plans and delivered fenestration. The industry has migrated from static CAD files to full Building Information Modeling (BIM) Level of Development (LOD) 350/400 models containing physical metadata, fastening schedules, and thermal boundaries.
Our OEM workflow provides comprehensive BIM parametric families early in the design phase. Real-time factory progress tracking, milestone video inspections, and container barcode scanning ensure commercial contractors maintain tight critical-path scheduling across multi-million dollar contracts.
Navigating municipal building codes requires empirical documentation, not sales conjecture. DERCHI fenestration products are backed by exhaustive third-party laboratory test reports that satisfy the International Building Code (IBC), International Residential Code (IRC), Australian NCC, and European CE harmonized fenestration standards.
Our products have passed the pinnacle AS 2047 N6 Cyclonic Rating, demonstrating water resistance beyond 700 Pascals and structural serviceability pressures exceeding 4,500 Pascals. When you specify our custom OEM aluminum glazed windows, your local building inspector receives an unassailable engineering submittal package.
