Why International General Contractors & Architects Partner With Us
Operating from Foshan, Guangdong—the world’s epicentre of precision aluminum processing—Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands as an elite OEM/ODM fenestration exporter.
Fully Integrated Supply Chain
From 6063-T6 billet alloy melting and precision die extrusion to vertical electrostatic fluorocarbon (PVDF) powder coating lines, every stage is controlled in-house to maintain 0.1mm tolerances across complex curtain wall and window schedules.
North American & Oceanian Audited
Our fenestration assemblies routinely undergo third-party laboratory verification, holding Australian AS 2047 (N6 cyclone rating), American AAMA/WDMA/CSA 101/I.S.2/A440-11, CE mark, and UL fire-rated door assemblies.
Dedicated BIM & CAD Engineering
Our bilingual structural design department converts architectural drawings into precise CAD submittals, glass wind-load calculation sheets, and 3D Revit models within 48 hours to streamline architectural review boards and municipal permitting.
Export-Grade Protective Packaging
Every single frame and insulated glass unit is encased in scratch-proof protective film, cushioned with dense closed-cell EPE foam, corner-guarded, and crated in fumigated solid plywood cases engineered for breakbulk or FCL intermodal handling.
Macro Trends Transforming Global Architectural Aluminum Procurement
Commercial developers, custom homebuilders, and large-scale importers are shifting procurement strategies to navigate carbon taxation, energy codes, and building lifecycle expectations.
Decarbonization & Circular Aluminum
Driven by the EU Carbon Border Adjustment Mechanism (CBAM) and North American LEED v4.1 mandates, enterprise procurement now prioritizes low-carbon primary aluminum smelted with renewable hydro power alongside post-consumer scrap recycling rates surpassing 40%.
Deep Facade-Building Automation (BMS)
Stand-alone windows are being superseded by motorized, sensory-enabled fenestration. Actuated casements, automated drop-down bifold servery windows, and bioclimatic motorized louvers integrate into KNX, Zigbee, and Crestron building control systems for passive ventilation optimization.
HVHZ & Climate-Resilient Envelopes
With extreme weather events intensifying worldwide, demand for High-Velocity Hurricane Zone (HVHZ) impact certification has expanded beyond coastal Florida into the Caribbean, Southeast Asia, and Pacific coastlines, necessitating structural silicone glazing and thick DuPont SentryGlas interlayers.
Comparative Thermal Performance Benchmark
Thermal barrier advancements engineered at our Foshan testing facility demonstrate how PA66GF25 multi-cavity polyamide barriers dramatically outperform conventional uninsulated and standard PVC window assemblies under ASTM C1363 testing conditions.
Overall Envelope Energy Efficiency Optimization: Up to 48% reduction in HVAC thermal bridge loss.
Technical Specification & International Code Verification
Engineered fenestration requires absolute transparency in metallurgy, thermal breaks, hardware durability, and environmental endurance tests.

Step-by-Step B2B Factory Sourcing Protocol
A transparent, risk-mitigated export framework providing predictability from initial architectural drafting to container unloading at destination ports.
1. Plan Review & Optimization
Architectural plan elevations, window schedules, and wind-zone specifications are ingested by our engineering department for value-engineering recommendations and glass calculation validation.
2. Detailed CAD Submittals
Prior to machine cutting, our draftsmen generate millimeter-accurate 2D/3D shop drawings detailing anchor fasteners, sill pans, jamb depths, and expansion joints for client architect sign-off.
3. Production & Factory Trial Run
Full-size mockups of folding doors and hurricane casements undergo dry-assembly in our 180,000m² facility. Hardware operation, gasket compression, and frame squareness are audited on video.
4. Intermodal Freight Logistics
We handle customs documentation, ISF filings, export packaging, marine cargo insurance, and FOB/CIF/DDP shipments directly to US, Canadian, Australian, European, and Middle Eastern ports.
Procurement & Technical Engineering Clarifications
Crucial commercial, technical, and regulatory answers for overseas procurement officers, developers, and trade importers.
Q1 How do your aluminum windows meet North American NAFS and Florida NOA standards?
Our export lines utilize 6063-T5/T6 alloy profiles with minimum wall thicknesses of 2.0mm to 3.0mm, structural silicone glazing (Dow Corning 983/995), reinforced steel stiffeners inside lock jambs, and laminated impact glass with Kuraray SGP or Saflex PVB interlayers. Our systems have successfully completed test protocols covering ASTM E1886, ASTM E1996, and TAS 201/202/203.
Q2 What are the lead times for custom bespoke architectural orders?
Standard custom architectural orders generally require 20 to 35 business days for factory production following final CAD shop drawing approvals and hardware finish selection. For large-scale container-volume commercial projects, we establish milestone batch delivery schedules aligned directly with your jobsite construction milestones.
Q3 What type of thermal break technology is incorporated in your profiles?
We engineer multi-chamber extruded profiles featuring genuine Technoform® glass-fiber-reinforced polyamide insulation strips (PA66GF25). This structure physically isolates the exterior and interior aluminum extrusions, eliminating condensation risks and lowering frame U-values to meet or exceed Energy Star and European Passivhaus thermal requirements.
Q4 How is glass breakage prevented during transoceanic shipping?
We deploy industrial-grade export crating protocols. Insulated glass units (IGUs) and assembled frames are wrapped with protective scratch-resistant polyolefin films, padded with corner impact blocks, and crated within steel-banded, fumigated solid timber or composite plywood crates. Desiccant packs prevent transit moisture clouding.
Q5 Can hardware be specified to North American or European hardware preps?
Yes. Our CNC machining centers route precision lock cutouts tailored to North American mortise locks, multi-point latch systems, Schlage/Kwikset deadbolt preps, or top-tier European hardware brands including German Siegenia, Hoppe, GU, Sobinco, and Italian Giesse systems.
Q6 What warranties and post-installation technical assurances are provided?
DERCHI backs all aluminum architectural extrusions with a 10-to-25-year structural warranty depending on surface coating classification (AAMA 2604/2605), 10 years on insulated glass unit seal integrity, and 5 to 10 years on hardware moving mechanisms, accompanied by complete installation manuals and bilingual video assistance.
