Explore our core certified entry door product lines engineered for global architecture, luxury villas, and high-security installations.
Redefining physical entry security through advanced materials science, multi-tier thermal barriers, and structural engineering compliance.
DERCHI high-security entry doors feature an internal heavy-duty carbon steel matrix encased within dual SUS304/SUS316 stainless steel skins or 6063-T5 high-tensile extruded aluminum profiles. Designed to withstand mechanical forced entry, physical impact, and severe shear forces, our systems deliver unprecedented physical protection for modern residential estates and high-value commercial assets.
Elimination of thermal bridging is achieved using precision-engineered multi-chamber polyamide (PA66 GF25) thermal insulation bars. By separating exterior aluminum/steel skins from internal decorative fascias, DERCHI doors achieve low thermal transmittance (U-values down to 1.6 W/m²K), preventing interior condensation while reducing HVAC energy loads significantly across extreme hot or freezing climates.
For large-format architectural entry doors up to 2000mm wide by 4000mm high, DERCHI integrates German-engineered floor spring pivot assemblies rated up to 500kg. Equipped with 3D multi-axis adjustments, hydraulic self-closing control, and hold-open features, these systems allow massive structural doors to glide effortlessly with minimal operational force.
How DERCHI is pioneering smart mechatronic integration, ballistic armor shielding, and carbon-neutral production lines for the next generation of architectural entrances.
The future of physical access control lies in seamless, invisible mechatronic hardware. DERCHI’s R&D department is embedding motorized multi-point automatic locking systems directly into door frames. Connected via encrypted Zigbee, Matter, or RS485 protocols, our doors support 3D biometric facial scanning, vein recognition, and remote smart building management without compromising manual override security.
Meeting international anti-terror and extreme security requirements, DERCHI is expanding its bullet-resistant (UL 752 Level 3 to Level 8) and explosion-proof entry door series. Utilizing multi-layered ceramic-composite backing plates, high-density aramid fiber interlayers, and heavy cast aluminum skins, these assemblies deliver military-grade physical protection in refined architectural finishes.
In accordance with global ESG directives, DERCHI utilizes 100% recyclable primary 6063-T5 aluminum alloys processed with zero-VOC electrostatic powder coatings and marine-grade PVDF (Polyvinylidene Fluoride) surface treatments. Our eco-friendly surface finishing guarantees 25+ years of color fastness and resistance against salt-spray degradation without toxic off-gassing.
Targeted door engineering configurations tailored to diverse geographic microclimates, structural building codes, and architectural typologies.
High-end single-family residential projects demand statement architecture without sacrificing family security. DERCHI provides bespoke cast-aluminum panels, custom hand-carved solid brass details, and oversized glass pivot doors. Equipped with multi-point hook locks and concealed automatic drop-down bottom seals, these doors ensure maximum airtightness, noise reduction (>38 dB), and anti-burglary performance (RC3 rating).
Commercial office towers and luxury hotels require heavy-duty cycle endurance. DERCHI's commercial pivot and sliding entry solutions undergo 500,000-cycle operational testing. Integrated with panic hardware, emergency keycard override systems, and fire-rated mineral core insulation, our commercial entrances balance high foot-traffic efficiency with strict life-safety compliance.
Projects in coastal Florida, Australia, or Southeast Asia require rigorous wind-load and hurricane protection. Tested to AS2047 N6 and ASTM E1886/E1996 missile-impact standards, DERCHI hurricane-rated entry doors utilize heavy-wall aluminum extrusions, laminated storm-glass, and corrosion-proof 316 stainless steel hardware that withstands wind pressures up to 3000 Pa.
Inside DERCHI’s 180,000 square meter smart production ecosystem: precision automation, total vertical integration, and zero-defect quality control.
Located in Foshan, China's premier architectural hardware capital, DERCHI operates a fully integrated manufacturing facility covering profile extrusion, thermal break strip insertion, 5-axis CNC machining, precision laser cutting, robotic welding, and automated surface coating lines. By eliminating sub-contractor friction, we maintain dimensional tolerances within ±0.5 mm across mass production orders.
Every single door frame and leaf manufactured at DERCHI passes five mandatory QC checkpoints: material tensile testing, structural corner joint load verification, electrostatic coating thickness measurement, water tightness chamber testing, and pre-shipment trial assembly. This rigorous protocol maintains our global transit defect rate well below 0.3%.
Our strategic Foshan location provides direct access to raw material aluminum foundries, premium glass processors, and international port hubs (Guangzhou / Shenzhen). With a standard production lead-time of 25–35 days following CAD sign-off, DERCHI offers global builders, distributors, and real estate developers unparalleled delivery reliability and inventory security.
How DERCHI supports commercial purchasing managers, architects, and master contractors through complete technical transparency, custom engineering, and international logistics packaging.
Procurement teams need precise drawing schedules before placing factory orders. DERCHI’s in-house engineering team issues full CAD shop drawings, elevation profiles, threshold anchorage details, and BIM-ready Revit blocks within 24–48 hours of project receipt, ensuring smooth coordination with site architectural plans.
We simplify local authority approvals by providing complete certification compliance packages. DERCHI door systems hold ISO 9001 certification, CE structural markings, Australian AS2047 testing compliance, and UL fire-rating test documentation, allowing fast site sign-offs across North America, Europe, Australia, and the Middle East.
Long-distance ocean transport requires superior protective packaging. Every DERCHI entry door unit is wrapped in scratch-resistant protective film, fitted with heavy-duty EPE foam corner guards, sealed in multi-layer corrugated cartons, and crated within solid, fumigation-free plywood crates labeled per opening schedule.

In-depth responses from DERCHI Senior Door Engineers to assist architects, procurement teams, and importers during technical specification.
DERCHI high-security entry door systems are manufactured under a certified ISO 9001 quality management protocol. Our product lines carry full CE compliance documentation for the European Union, AS2047 N6 wind and water penetration test reports for Australia and New Zealand, and UL-referenced fire resistance ratings for commercial lobby applications. Complete certification testing dossiers and factory mill certificates are released alongside detailed project quotation packages.
While standard residential door openings average 1200mm × 2400mm, DERCHI specializes in oversized custom architectural pivot doors. Our factory routinely engineers single pivot leaves up to 2000mm in width and 4000mm in height. These oversized units incorporate internal steel-core tensioners to prevent thermal bowing, paired with heavy-duty German floor springs rated for up to 500kg leaf weights.
To support architectural prototyping and custom luxury residential projects, DERCHI maintains flexible OEM minimum order criteria. Sample units for testing or showroom display take approximately 12–18 days to produce. Commercial volume project orders typically require 25–35 production days following final shop drawing approval and deposit receipt.
All DERCHI security doors utilize multi-point hook locking gear (including 3 to 7 locking points), anti-pry interlocking hinge pins, and drill-resistant manganese steel lock cylinder guards. Our systems are fully compatible with European profile key cylinders and motorized smart locks, achieving EN 1627 RC3 to RC4 resistance classes against mechanical forced entry tools.
Yes. DERCHI operates as a dedicated OEM/ODM manufacturer. Builders, architects, or door importers can submit existing door schedules, CAD sections, or specific brand target specifications. Our technical engineering division will generate an equivalence matrix showing direct profile, thermal, and security matches to fulfill your exact project schedule.
