Explore our CE-compliant fenestration and entrance systems, precision-machined in our 180,000 m² facility with structural performance testing for commercial and ultra-luxury residential builds.
Dedicated production base in Foshan with integrated precision CNC processing.
Decades of technical leadership in high-end structural door and window systems.
Strict adherence to CE EN 14351-1, ISO 9001, AS 2047, and UL fire standards.
Senior engineers and assembly technicians providing project-ready execution.
Unlike standard butt-hinged entrances, architectural pivot doors transfer structural loads directly to the floor substrate, enabling dramatic structural spans while demanding superior thermal breaks and airtightness control.
Our systems incorporate floor-recessed hydraulic systems engineered to accommodate panel loads upwards of 800 kg (1,760 lbs). Featuring 360-degree adjustable pivot pins, mechanical self-closing speeds, and 90-degree hold-open functionality, each set is cycle-tested beyond 500,000 openings without sag or mechanical failure.
Overcoming the historical thermal vulnerability of oversized doors, we employ high-density PA66 GF25 thermal breaks coupled with aerodynamic insulated cores. This architecture yields overall thermal transmittance values as low as UD ≤ 0.92 W/(m²·K), meeting strict European Passivhaus and GEG benchmarks.
To eliminate air infiltration at the floor clearance, our doors utilize automated mechanical drop seals. Upon door closure, twin high-resilience EPDM gaskets deploy automatically to compress firmly against zero-barrier, flush-floor architectural thresholds, achieving Class 4 Air Permeability (EN 12207) and Class 8A Water Tightness (EN 12208).

Procurement directors and project developers face shifting regulatory demands and evolving aesthetic expectations. Here is where the high-end entrance door market is heading over the next five years.
The global demand for massive proportions continues to accelerate. Portals exceeding 2.4m in width and 4.0m in height are moving from custom novelties to standard specifications in modern architectural designs. Engineering focuses heavily on structural extrusion thickness (≥ 3.0mm) to eliminate thermal bowing caused by extreme temperature differentials between indoor and outdoor faces.
Mechanical keys are increasingly obsolete in premier residential projects. The standard is now seamlessly integrated motorized multipoint locks driven by concealed facial recognition, biometric finger scanners, or home automation systems (KNX, Crestron, Control4). Concealed cable power loops inside the pivot axis provide continuous clean power delivery without exposed wiring.
Aluminum frameworks are increasingly mated to exotic outer skins. Procurement trends show architectural demand for aluminum pivot doors clad in sintered porcelain stone, real wood veneers protected by fluorocarbon resin, cast bronze relief panels, and anti-glare architectural safety glasses. This hybrid approach blends the structural stability of metal with artisan exterior textures.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands among China's top tier fenestration manufacturers. We serve as a direct factory bridge for European contractors, developers, and architectural firms.
Our manufacturing precision is demonstrated by our partnership with a long-standing UK Schüco installation partner, who selected DERCHI to manufacture complex architectural portals for a multi-villa development. Our components meet the strict tolerances and engineering rigour expected of Europe's top building system brands.
Eliminate procurement guesswork before running aluminum extrusions. Our in-house technical department of over 40 engineers generates detailed CAD drawings, threshold elevation details, glass load calculations, and BIM assets based on your architectural schedules, ensuring zero field errors during final assembly.
Cross-border procurement simplified. Our bilingual sales engineers operate aligned with European and British time zones, giving you rapid access to project quotes and technical support. Shipments leave our Foshan base packed in ISPM-15 reinforced plywood crates, landing smoothly at ports such as Rotterdam, Hamburg, Antwerp, and Felixstowe.
Clear, technical answers to the most common queries raised by quantity surveyors, facade consultants, and general contractors.
We supply a complete Declaration of Performance (DoP) compliant with European standard EN 14351-1:2006+A2:2016. Every door assembly is tagged with its individual CE label, accompanied by factory production control (FPC) certificates and accredited lab test results covering air permeability, water tightness, wind resistance, and thermal transmittance.
When tall entrance doors face direct sun outside while the interior is air-conditioned, the temperature delta can cause panels to bow. We solve this by using anti-bi-metal polyamide insulating strips within the thermal breaks, alongside rigid structural aluminum alloy (6063-T6 / 6061-T6) profile walls measuring 3.0mm to 4.0mm thick, keeping the leaf true across seasons.
Yes. We regularly prepare custom CNC millings for third-party European hardware brands including Dormakaba, FritsJurgens, GU, and Siegenia. We also supply our own CE-certified motorized locking assemblies compatible with smart intercoms, keypad panels, and home automation networks.
Custom fabrication takes 25 to 35 working days following final CAD drawing and finish sign-off. Ocean freight to primary European ports typically requires 28 to 35 days. Every crate is custom-built with moisture barriers and impact-resistant internal cushioning to guarantee arrival in zero-defect condition.
