Recognized as an industry-leading manufacturer, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) combines massive manufacturing infrastructure with precise European machining standards to satisfy the world’s most exacting architectural requirements.
Our centralized production hub in Foshan, Guangdong encompasses automated CNC multi-axis profile machining, precision miter cutting, robotic argon-filled glass assembly, and comprehensive testing labs designed for high-capacity global contract orders.
Holding over 30 independent invention and design patents alongside CE, ISO 9001, AS 2047 N6, NFRC, and UL fire-rated certifications. Every custom production batch is traceable and verified with certified laboratory testing submittals for local building authority sign-offs.
From custom profile die development to specialized architectural hardware, our in-house structural engineering department provides parametric BIM/CAD shop drawing modeling, custom color-matching PVDF finishes, and tailored acoustic insulation treatments.
A fenestration unit specified for temperate zones will degrade rapidly under the brutal thermal shocks and particulate loads of the Arabian Gulf or coastal cyclonic zones. Our specialized OEM/ODM assemblies are calculated against intense thermal expansion, sand abrasion, and marine air corrosion.
As international energy conservation codes tighten and developers demand rapid turnkey cycle times, commercial door procurement is shifting away from fragmented component sourcing to vertically integrated contract manufacturing.
Stringent updates to ASHRAE 90.1, California Title 24, and GCC Estidama codes require whole-assembly U-values under $1.4\text{ W}/(\text{m}^2\cdot\text{K})$. Thermal break chamber depths are expanding with aerogel insulation inserts.
Enterprise buyers require concealed motorized operators, electromagnetic latches, and IoT-driven access controllers pre-channeled into structural frames during factory extrusion, eliminating on-site post-drilling.
Tier-1 contractors demand certified low-carbon primary billets smelted using renewable hydro-power, combined with closed-loop factory scrap reclamation to meet LEED v4.1 and BREEAM whole-life carbon credits.
To slash expensive on-site field labor in the US, Europe, and GCC, procurement teams are ordering fully unitized, factory-glazed subframe systems that install with concealed anchoring brackets in hours.

How global developers, architects, and engineering contractors collaborate with our Foshan manufacturing base to guarantee specification compliance from initial concept through job-site installation.
Our senior fenestration engineers review project schedules, wind-load calculations, and architectural opening elevations, providing parametric 2D/3D CAD shop drawings and static deflection calculations for structural consultant approval.
When custom sightlines are mandated, we produce custom precision extrusion dies within 15–20 days. Extrusions are cast from virgin 6063 or 6061 billet aluminum, quenched to T5/T6 temper, and finished via anodizing or 3-coat fluorocarbon PVDF lines.
Computer-controlled double-miter saws cut profiles to ±0.2mm precision. Thermal barrier insertion, pneumatic corner crimping, and high-frequency gasket vulcanization are executed in automated work cells to guarantee hermetic joint sealing.
Glazing units (IGUs) are assembled in temperature-controlled cleanrooms utilizing robotic primary polyisobutylene (PIB) extrusion and secondary structural silicone sealing. Units feature argon fill levels >90% and warm-edge composite spacer technology.
Prior to export packaging, randomized sample leaves undergo 50,000-cycle mechanical endurance tests, corner-weld break loading, laser alignment checks, and water spray testing to eliminate field assembly defects.
Finished assemblies are wrapped in moisture-barrier film, protected with high-density EPE edge protectors, and secured into fully fumigated, steel-banded plywood crates engineered for intermodal container maritime transit without racking.
Direct technical answers addressing the critical specification, testing, MOQ, and logistical requirements evaluated by procurement teams and architectural consultants.
For catalog systems using standard master dies, our MOQ starts at just 1 complete set for bespoke villa projects or prototype sample verification. For proprietary custom architectural extrusion profiles requiring dedicated extrusion dies, the standard tooling threshold is typically 500 kg to 1 ton per profile section. If overall project extrusion volumes exceed 5 tons, custom die tooling fees are credited back to the contractor's account.
Middle Eastern installations are subject to extreme diurnal temperature fluctuations causing thermal expansion and contraction. We utilize multi-chambered polyamide strips (Technoform PA66 GF25) that share the same coefficient of thermal expansion as aluminum alloy, preventing shearing or bow distortion. Additionally, our continuous dual-durometer vulcanized EPDM gaskets are chemically resistant to sand abrasion and high-intensity ultraviolet oxidation, ensuring no air leakage or sand ingress during seasonal shamal storms.
Yes. We routinely supply comprehensive engineering submittal packages including certified laboratory test results for air permeability (ASTM E283), static water penetration resistance (ASTM E331), uniform structural load capacity (ASTM E330), acoustic isolation (ASTM E90), and thermal transmittance calculations (ISO 10077 / NFRC). For European, Australian, and Middle Eastern authorities, we supply verified CE dossiers, AS 2047 certificates, and UL fire test documentation.
Our profile milling is universally compatible with industry-standard Euro-groove and custom CNC mortise configurations. We natively integrate world-renowned European hardware systems including Siegenia, GU, Roto, Hoppe, and Dormakaba, alongside heavy-capacity concealed pivot hinges capable of carrying leaf weights up to 800 kg. Smart electric strikes, motor-driven perimeter locks, and biometrics (fingerprint, facial recognition, RFID, Zigbee/Tuya home automation) can be pre-wired and factory installed.
Standard architectural finishes (anodized black, bronze, silver, or RAL standard powder coatings) typically require 25 to 30 business days following shop drawing sign-off and deposit receipt. Fully bespoke configurations involving new extrusion tooling dies, specialized PVDF metallic finishes, or triple-laminated ballistic-rated glass require approximately 35 to 45 business days. Expedited production slots can be reserved for time-critical commercial hotel or infrastructure milestones.
Every product undergoes a multi-layer protective packaging sequence: (1) low-tack protective film on all visual extrusion faces; (2) high-density expanded polyethylene (EPE) foam edge buffers; (3) fully enclosed, ISPM-15 certified fumigated heat-treated timber crates with internal cross-bracing and desiccant bags to prevent oceanic humidity condensation. Oversized glass assemblies are shipped on reinforced steel A-frames secured directly to 40ft HQ or Open-Top containers.
