Enterprise OEM/ODM Manufacturing Capabilities & Engineering Rigor
In modern fenestration architecture, a full glass door is no longer merely a visual transition—it serves as a primary environmental barrier requiring extreme structural rigidity, micro-millimeter dimensional tolerances, and multi-layered climatic resilience. Operating from our 180,000 m² state-of-the-art production base in Foshan, Guangdong, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) represents China's tier-1 industrial elite in precision aluminium systems manufacturing. With 25+ years of B2B production heritage, we manage complete vertical integration from metallurgical billet casting to precision extrusion, CNC multi-axis milling, automated glass processing, and robotic assembly.
Metallurgical Precision & Extrusion Control
Our architectural doors utilize prime virgin 6063-T5 and 6061-T6 aluminium alloy billets, completely free of re-melt scrap impurities. This raw material consistency ensures tensile strength > 215 MPa and yield strength > 160 MPa. Structural profiles undergo high-pressure extrusions through bespoke dies engineered with automated tolerance sensors, keeping axial variations within ±0.15mm per 6000mm length—exceeding standard ASTM B221 and GB/T 5237 benchmarks.
Surface treatments encompass marine-grade fluorocarbon (PVDF) 3-coat electrostatic spraying complying with AAMA 2605 guidelines, architectural hard anodizing up to 25μm (Class 1), and AkzoNobel powder coatings certified under Qualicoat Class 2. This guarantees zero peeling, micro-cracking, or chalking under intense UV indexes, coastal salt spray environments, or extreme tropical heat cycles.

Market Intelligence White Paper
B2B Global Procurement Trends (2025–2030)
Strategic shifts in international supply chain procurement, regulatory sustainability demands, and project cost engineering for aluminium glass door imports.
Direct Manufacturer Consolidation
Developers and general contractors are bypassing regional trading agents in favor of factory-direct OEM/ODM arrangements. Direct engagement cuts 18–25% in intermediaries' markup, accelerates CAD shop drawing revision speeds by 70%, and ensures uncompromised warranty accountability from single-source suppliers.
Low-Carbon & EPD Mandates
European and North American building codes are accelerating demands for Environmental Product Declarations (EPD). Tier-1 aluminium extruders must utilize scrap-traceable green aluminium smelted with renewable hydro-power, cutting embodied carbon below 4.0 kg CO2e per kg of primary billet.
Turnkey Prefabrication & Glazing
High on-site labour costs in target markets like Australia, the USA, and the UK make field-glazing economically unviable. Procurement contracts increasingly demand completely assembled, dry-glazed factory cassettes equipped with tested anchor brackets, reducing on-site installation schedules by up to 60%.
Climate-Targeted Engineering
Procurement teams reject generic off-the-shelf fenestration. Systems imported into South Asia, the Middle East, and coastal North America are engineered with heavy multi-point perimeter compression seals to eliminate tropical monsoon water penetration, salt-mist galvanic corrosion, and high-heat solar gain.
Engineering Evolution: Next-Generation Aluminium Full Glass Doors
The architectural envelope has shifted irreversibly toward visual transparency, structural lightness, and smart automation. Conventional heavy visible frames are giving way to structural glass systems where the aluminium profile transforms into an invisible perimeter chassis embedded directly into floor and ceiling finishes.
| Engineering Attribute | Legacy Aluminium Glass Doors | Next-Gen DERCHI OEM Systems | Architectural Benefit |
|---|---|---|---|
| Visible Sightlines | 80mm – 120mm heavy stiles | 18mm – 25mm Ultra-Slim | Maximizes daylight opening ratio up to 96% |
| Thermal Insulation | Non-thermal or 14mm PVC strip | PA66GF25 34mm Multicavity | U-values drop to 1.1 W/(m²·K), Passivhaus ready |
| Glazing Technology | Standard 6mm float or single laminated | Triple DGU + Argon + Low-E | SHGC < 0.28, sound attenuation up to Rw 44 dB |
| Smart Access Systems | Mechanical cylinder mortise locks | Concealed IoT Biometric Interlocks | 3D Face ID, Tuya/Zigbee integration, motorized drive |
| Sill Drainage Engineering | Raised 40mm step, passive weeping | Zero-Step Flush Sub-Sill Matrix | Barrier-free ADA compliance with 600Pa water seals |
Micro-Sightline Structural Floor Spring Pivot Systems
Modern mega-villas and flagship corporate lobbies demand continuous floor-to-ceiling panoramic glass panels exceeding 4.0 meters in height and up to 2.5 meters in width. To support sash weights up to 500 kg while maintaining effortless feather-touch operation, our engineering team integrates German hydraulic bottom-pivot bearing cartridges paired with high-tensile internal steel reinforcement tie-rods concealed within the vertical aluminium stiles. This counteracts wind-induced sash deflection and prevents structural frame sag across decades of heavy cycling.
Electrochromic Dynamic Glass Integration (PDLC / Smart Tint)
In high-end architectural and executive office applications, liquid crystal switchable privacy glass (PDLC) is being integrated directly into the factory-glazed insulated units. Electrical contact points are run invisibly through specialized wire-transfer pivot hinges or continuous concealed brush raceways. At the flip of a wall switch or smartphone prompt, the glass transitions from 88% crystal transparency to completely private opaque white within 20 milliseconds, providing intelligent thermal shading and solar reflection.
Technical & Procurement Due Diligence
Comprehensive B2B Procurement FAQ
In-depth answers addressing logistics, quality assurance, CAD detailing, container packing, and technical specifications for international project owners and import distributors.
What are the exact technical specifications of your aluminium profiles and alloy certifications? +
We exclusively extrude primary 6063-T5, 6063-T6, and 6061-T6 structural aluminium alloys strictly compliant with ASTM B221, EN 755, and GB/T 5237 standards. Wall thicknesses for our heavy sliding, stacking, and commercial storefront series range between 2.0mm and 3.0mm in load-bearing web sections, ensuring extreme structural stability against cyclonic gusts. Mill test certificates (MTC) detailing chemical composition (Si, Fe, Cu, Mn, Mg, Cr, Zn, Ti) and mechanical tensile/yield curves are provided with every export batch.
How does your factory prevent water leakage during extreme monsoon rainfall and windstorms? +
Our systems utilize a multi-barrier waterproofing design based on the "equal pressure chamber" aerodynamic principle. High-grade continuous vulcanized EPDM gaskets (imported from Germany/industrial tier-1 sources) ensure uninterrupted perimeter compression under multipoint shootbolt engagement. Furthermore, our stepped sill designs integrate concealed, one-way drainage flutter-valves and subterranean baffled sub-sills that channel wind-driven rain away even during sustained 700 Pa static water pressure tests (equivalent to a category-2 tropical storm).
Can your engineering team provide custom CAD shop drawings, BIM models, and structural calculations? +
Yes. Our in-house engineering team comprises 50+ experienced façade structural designers and draughtsmen. Upon receipt of your architectural window/door schedules or elevation DWG files, we generate full 2D AutoCAD fabrication shop drawings, 3D section details, Revit BIM families, and structural wind-load deflection calculations (FEA) within 48 to 72 hours. All shop drawings must be client-signed and approved prior to extrusion CNC toolpath programming.
What glass configurations and safety certifications are offered for international export? +
We process standard, low-iron (ultra-clear), tinted, reflective, and Low-E glass variants certified under ANSI Z97.1 (USA), AS/NZS 2208 (Australia), and CE EN 12150 / EN 12600. Common setups include 6mm+12A+6mm tempered double-glazed units (DGU), 8mm+1.52PVB/SGP+8mm hurricane-proof structural laminated glass, and triple-pane sound-dampening units filled with 95% pure argon gas. All insulating units utilize dual silicone containment with continuous polyisobutylene primary vapor seals.
What is the standard production lead time and minimum order quantity (MOQ) for custom OEM projects? +
For standard extrusion finishes (standard architectural black, matte grey, anodized bronze, natural silver), our production cycle is 25 to 30 business days following shop drawing confirmation. Bespoke PVDF custom-matched RAL colors or custom extrusion mold creation requires 35 to 40 days. We maintain high flexibility for bespoke projects: there is no rigid square-meter MOQ for custom private residential villas, while full container load (FCL) volume orders benefit from staggered batch scheduling and dedicated project management.
How do you guarantee that oversized glass doors arrive completely undamaged during long ocean transit? +
Export packing is handled via our standardized 5-tier safety packaging protocol: 1) Protective static-peel polyfilm across all aluminium surfaces; 2) High-density closed-cell EPE foam edge and corner bumpers; 3) Vacuum waterproof bubble-wrap enclosure; 4) ISPM-15 certified non-coniferous fumigated multi-plywood crates with built-in interior rubber vibration dampening buffers; 5) Steel-band exterior strap bracing. Crates are loaded with heavy-duty forklift lifting eyes and balance indicators to eliminate container shifting during ocean voyages.
What shipping terms and international delivery logistics do you accommodate? +
We operate fully under Incoterms 2020, offering FOB (Shenzhen / Guangzhou / Foshan), CIF (major worldwide seaports including Nhava Sheva, Mundra, Karachi, Colombo, Sydney, Melbourne, Los Angeles, Rotterdam), and DDP (Delivered Duty Paid directly to your warehouse or job-site). We manage full customs documentation, certificates of origin (Form A, Form E, CO), packing lists, commercial invoices, and bill of lading releases.
What warranties and post-delivery installation support do you provide? +
We provide a 10-year structural warranty on aluminium extruded frames and surface coating integrity, alongside a 5-year warranty on insulated glass edge seals and moving hardware mechanisms (rollers, handles, multi-point locks). Every project shipment includes exploded 3D installation blueprints, printed technical fixing manuals, and step-by-step video guides. Our English-speaking fenestration engineers provide remote real-time teleconference guidance during on-site subframe setting and sash calibration.
