Our turnkey OEM/ODM production covers precision thermal breaks, structural hurricane impacts, narrow-profile minimalist designs, and motorized luxury overheads. Review our factory-direct export product schedule below.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates China’s premier automated production complex, redefining industrial entry systems for architects and B2B distributors in over 60 countries.
With more than 25 years of engineering experience, our integrated facility bridges profile extrusion, multi-axis CNC fabrication, computerized fluorocarbon (PVDF) powder coating, and robotic glass assembly. For global developers and commercial procurers, DERCHI serves as a single accountable partner: eliminating supply chain intermediaries, enforcing zero-defect QA protocols, providing complimentary structural CAD drawings, and issuing export-ready crate packaging built for rigorous ocean transport.
Modern luxury entry portals must satisfy intense thermodynamic resistance, extreme air-tightness, and uncompromised ballistic and forced-entry deterrence. Examine the technical mechanics behind DERCHI's proprietary engineering.
We utilize primary virgin billets with strictly controlled magnesium-silicon stoichiometry. Solution heat-treated and artificially aged to T6 temper, providing a tensile yield strength exceeding 215 MPa to prevent frame distortion in massive pivot panels reaching 4.5 meters in height.
By isolating interior and exterior extruded skins using 25% glass fiber reinforced Polyamide 6.6 insulation bars, DERCHI portals eliminate thermal bridges, dropping overall assembly U-factors down to 0.18 BTU/(hr·ft²·°F) [1.02 W/(m²·K)] for zero condensation in harsh alpine or humid tropical zones.
Our pivot hardware relies on hardened German roller bearings rated up to 1,200 kg panel loads with 360-degree precision damping. Perimeter anti-lift multi-point locks integrate motorized deadbolts compatible with biometric scanners, facial recognition, and smart building KNX protocols.

Strategic B2B purchasing in the façade and fenestration sectors is rapidly pivoting from basic cost metrics to lifecycle sustainability, structural resilience against climate disruption, and seamless container optimization.
Global building codes increasingly mandate strict hurricane-proof and cyclonic certification, even in non-coastal regions. Procurers are specifying Florida NOA and AS2047-certified frames capable of resisting sustained projectile impacts and torrential rain backpressures.
European and North American ESG rules penalize high-carbon metal manufacturing. DERCHI leverages hydroelectric-powered aluminum smelting billets, allowing international contractors to present low-carbon environmental product declarations (EPDs).
Importers are minimizing multi-vendor ocean freight overhead by sourcing front entrance pivot doors, interior soundproof systems, minimalist terrace sliders, and overhead garage doors within a single factory-inspected, consolidated container.
The standard manual lock is obsolete in luxury construction. Modern high-end procurement schedules require concealed cable transfers, motorized locking latches, and integrated mobile-app-managed access control built into the factory sash frame.
Tested and pre-approved for CE, ISO9001, AS2047 (Australia), NFRC / NOA (USA), and UL Fire Standards.
From architectural sketches to on-site assembly, our structured process ensures accurate dimensional control, zero site rework, and transparent project tracking for project developers and façade engineers.
We review opening elevations, wind load calculations, coastal salt spray levels, and local building energy requirements. Our engineering team converts your project parameters into millimeter-accurate CAD shop drawings free of charge.
Profiles are cut, punched, and milled using automated 5-axis German CNC machines. Miter joints are reinforced with cast aluminum corner cleats and crimped with dual-component anaerobic polyurethane structural adhesive.
Automated vertical powder-coating lines apply marine-grade AkzoNobel fluorocarbon finishes. Insulated tempered laminated glass units with warm-edge warm spacers and argon gas are structurally bonded into place.
Every custom door undergoes full pre-hanging in our inspection bay: verifying sash alignment, hinge friction, weatherseal compression, electronic latch release, and laser squareness before approval.
Doors are wrapped in multi-layer protective PE film, edge-protected with high-density EVA shock absorbing foam, and encased in fully sealed, fumigated OSB plywood crates engineered for crane and forklift handling.
We supply step-by-step 3D exploded assembly diagrams, anchorage schedules, and live video engineering support synced to your time zone (covering North America, Europe, Australia, and South America).
Essential engineering, logistical, and commercial inquiries answered by our Senior Façade Technical Directors.
Solid wood entry doors in high-humidity or direct sun exposures suffer from hygroscopic expansion, warp, UV bleaching, and insect degradation. Traditional mild steel doors are vulnerable to galvanic oxidation and salt corrosion along hidden weld seams. DERCHI engineered 6063-T6 aluminum doors combine total structural stability with zero moisture absorption, superior resistance to marine salt mist via AAMA 2605 fluorocarbon finishes, and thermal-break insulation performance that achieves U-values unobtainable with uninsulated steel or solid hardwood.
Yes. We regularly fabricate oversized architectural pivot entrance portals reaching up to 3000mm (10 feet) in width and 5000mm (16 feet) in height. To manage self-weight and dynamic wind flutter, we use heavy-wall internal structural steel subframes encased in extruded alloy skins. The pivot mechanisms utilize heavy-duty German FritsJurgens or Dorma-Kaba concealed self-closing hydraulic pivots with adjustable damping, closing force control, and 90° hold-open detention, rated for panel weights exceeding 800 kg to 1,200 kg.
Direct contact between aluminum and stainless steel in humid or saline coastal air triggers galvanic corrosion due to differences in electrical potential. DERCHI implements complete electrical isolation: all mounting screws, hinges, and lock cases use non-conductive EPDM or polyamide isolation shims, nylon collar sleeves, and Dacromet-coated fasteners, preventing electrolyte bridge formation and ensuring structural integrity in harsh coastal environments.
Every commercial production run is accompanied by project-specific testing records. We supply CE declarations of performance (EN 14351-1), ISO9001 quality certificates, AS2047 mechanical and water penetration test reports for Australia, NFRC thermal performance ratings, and Florida NOA / ASTM impact hurricane test data. Our technical office works directly with your façade consultants and local municipal plan examiners to verify engineering compliance prior to shipment.
Standard lead times for custom architectural OEM orders are 25 to 35 calendar days following final CAD drawing sign-off and deposit receipt. We routinely provide container consolidation services: combining front entry doors, interior soundproof aluminum swing doors, minimalist sliding systems, and overhead glass garage doors in a single 40ft HQ container. Each unit is tagged with opening location codes matching your architectural schedule for rapid on-site staging.
To eliminate moisture ingress, vibration scouring, and container shifting during extended maritime voyages, all doors undergo a 4-tier packaging protocol: (1) Anti-static surface wrapping; (2) Closed-cell EVA foam edge guards; (3) Heavy corrugated surrounding corner buffers; (4) Fully enclosed structural OSB wooden crates lined with moisture-absorbing silica desiccant bags. Crates feature integrated 100mm forklift skids and heavy internal corner strapping to guarantee pristine arrival.
