As a certified OEM/ODM manufacturing facility based in Foshan, Guangdong, our high-performance aluminum impact window and door configurations are engineered to withstand extreme cyclonic wind speeds, missile projectile impacts, and rigorous coastal salinity conditions across international residential and commercial developments.
High-precision 6063-T6 aluminum profiles with architectural fluorocarbon wood grain transfer, integrated thermal barrier break, and double laminated safety impact glazing.
Heavy-duty interlocking aluminum slats injected with rigid polyurethane foam for superior wind resistance, acoustic baffling, and motorized storm protection.
Heavy-duty bottom roller carriage with European multipoint perimeter locking, engineered EPDM weather seals, and SentryGlas impact interlayer configurations.
Architectural panoramic opening systems offering unobstructed viewing angles, reinforced track guide geometry, and impact-certified tempered glass.
Engineered load-bearing rafters, integrated hidden gutter systems, and high solar-heat gain reduction low-E laminated glass for all-weather sunroom enclosures.
Ultra-narrow sightline interlocking stiles engineered with internal steel reinforcement to achieve oversized sash dimensions and superior cyclical pressure resistance.
Anodized or matte black powder-coated slender profiles, soft-close dampening mechanisms, and tempered architectural glass engineered for interior acoustic separation.
German-engineered lift-and-slide hardware facilitating single sash weights up to 400kg, continuous high-performance weatherstripping, and exceptional U-values.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands among the top architectural fenestration manufacturers in China, operating a comprehensive industrial footprint in Foshan to support enterprise procurement worldwide.
Our facility integrates automated 4-axis and 5-axis CNC machining centers, automated corner-crimping machines, robotic silicone extrusion lines, and specialized assembly lines for structural glazing. By managing extrusion precision, thermal break insertion (using premium technoform polyamide PA66 GF25 strips), and glass laminating under strict ISO 9001 quality supervision, we eliminate micro-tolerances that lead to air infiltration or structural failure under intense hurricane conditions.
Our project track record includes multi-unit luxury villa developments in the UK, commercial coastal projects across Florida and the Caribbean, and high-wind-zone installations in Australia complying with AS 2047 N6 cyclonic testing benchmarks.
Building codes worldwide are tightening their envelope resilience criteria. Understanding shifts in structural interlayers, thermal regulations, and testing protocols is essential for commercial developers and architectural distributors.
Commercial developers are shifting away from fragmented multi-tier local middle distributors to direct-from-factory OEM/ODM procurement models. Consolidating impact windows, entrance doors, and curtain walls with an integrated supplier reduces container freight fragmentation and cuts overall procurement budgets by 30% to 45% while enforcing strict consistency across structural finishes.
Historically, impact fenestration focused primarily on mechanical projectile resistance. Current energy mandates, such as the UK Part L, Germany's GEG, and IECC updates in the United States, demand combined performance: deep thermal isolations achieving overall fenestration U-values ≤ 1.3 W/m²K, coupled with large missile impact ratings.
Traditional Polyvinyl Butyral (PVB) films are increasingly being upgraded to Ionoplast interlayer technology (Kuraray SentryGlas®). SGP delivers five times the tear strength and one hundred times the structural rigidity of standard PVB, maintaining glass barrier integrity and post-breakage load performance in high-velocity storm conditions.

We work exclusively with prime-grade 6063-T5/T6 architectural aluminum alloy ingots. Our heavy-duty impact profiles are extruded to structural wall thicknesses ranging between 2.0mm and 3.2mm, matching or exceeding international fenestration codes. Each raw production batch is supported by Mill Test Certificates (MTC) certifying tensile strength, yield strength, and chemical spectrometry compositions.
Yes. Our in-house engineering and drafting office generates detailed 2D CAD and 3D shop drawings, profile section details, and glazing schedules tailored to the architectural layouts of your project. We accommodate oversized configurations, customized mullion junctions, and specific glass buildups without requiring costly custom extrusion tooling for standard adaptations.
For high-salinity coastal conditions, we offer Qualicoat Class 2 certified powder coatings, high-performance AkzoNobel PVDF fluorocarbon coatings (AAMA 2605 compliant with a 20-year colorfast warranty), and deep anodic oxidation (Class 20/25). These protect the aluminum substructure against galvanic pitting, blistering, and UV deterioration.
Given the heavy deadweight of laminated impact glazing, we package units using protective blue surface film, multi-layer shock-absorbing pearl foam, heavy cardboard edge protectors, and steel-banded, heat-treated fumigated plywood crates. Units are secured to prevent internal flexing during transit, and we pack ocean containers using balanced dunnage systems for safe unloading.
DERCHI holds CE certification under EN 14351-1, ISO 9001 quality system registration, AS 2047 performance compliance verified by NATA-accredited test laboratories in Australia, and third-party laboratory reports covering ASTM E1886/E1996 impact standards. Full test reports and Declarations of Performance (DoP) are provided alongside engineering submittals.
Standard lead times for full 20GP or 40HQ container orders run between 25 and 35 working days following signed CAD shop drawing approval and color swatch sign-off. For specialized custom-engineered extrusion profiles or bespoke curved glass configurations, production runs are scheduled with clear critical path milestones.
From single-family luxury villas to institutional multi-story developments, our end-to-end manufacturing infrastructure simplifies global supply chains.
Selected by recognized European and British construction contractors as an alternative to European domestic brands, DERCHI supplies precision-machined window and door packages that deliver equivalent thermal and acoustic performance at substantial cost efficiency.
Eliminate supplier fragmentation. Our product catalog spans thermal break aluminum casement and awning windows, minimalist sliding doors, bi-fold patio walls, cast aluminum security entry doors, and motorized insulated roll-up shutter systems within a consolidated order.
Our bilingual project engineering team works alongside your architects and quantity surveyors during European, American, and Australian working hours, providing rapid CAD submittals, structural wind-load simulations, and comprehensive anchoring installation guides.
