Explore DERCHI's flagships engineered for extreme structural stability, multi-locking security, and architectural luxury.
In modern architectural design and high-end real estate development, an exterior entry door acts as both the primary statement of aesthetic luxury and the ultimate physical barrier against environmental extremes, forced entry, and ballistics.
DERCHI security entrance doors are tested in accordance with EN 1627-1630 standards. Featuring multi-layer reinforced internal steel frameworks, anti-drill manganese plates, and multi-point kinetic lock systems, our doors resist physical attacks from heavy hand tools, crowbars, cordless drills, and impact rams for extended durations.
Utilizing high-tensile 6063-T5 aluminum extrusions alongside solid A356 aluminum sand casting (6mm to 12mm thickness), DERCHI creates seamless double doors and grand villa gates. The surface features hand-polished patinas combined with fluoropolymer PVDF coatings to ensure zero oxidation, fading, or marine corrosion.
Our security doors seamlessly incorporate motorized European multi-point locks with 3D biometric facial recognition, encrypted RFID keycards, dual fingerprint sensors, and smart home IoT protocol connectivity (Zigbee, Z-Wave, Control4) with manual mechanical override cylinders rated to SKG*** security levels.
Located in Foshan—the world's capital of aluminum extrusion and fenestration engineering—DERCHI operates a fully integrated, vertically controlled 180,000 m² production base delivering unmatched B2B manufacturing economies of scale.
From raw billet aluminum casting and precision profile extrusion to automated German CNC milling, corner welding, thermal break strip insertion (PA66 GF25), and PVDF electrostatic painting, DERCHI maintains total quality control inside a single complex. This eliminates third-party component markups and ensures profile tolerances strictly within ±0.5mm.
Global distributors, residential hardware suppliers, and project contractors gain direct access to Chinese manufacturing economics. By streamlining automated production lines with over 600 skilled technicians, DERCHI delivers architectural-grade security doors at wholesale price points 30% to 50% lower than European equivalents without compromising material certified performance.
A high-security entrance door must adapt to local building codes, extreme thermal cycles, and stringent municipal compliance rules across different continents.
For US and Canadian project procurement, DERCHI doors are engineered to satisfy NFRC thermal conductivity guidelines (U-factors down to 0.24 BTU/h·ft²·°F) and Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) impact standards, featuring ADA-compliant low-profile thermal barrier thresholds.
Tested for coastal wind loads, cyclic water ingress, and air infiltration up to AS2047 N6 requirements (3,000 Pa wind load resistance). Ideal for coastal Queensland and storm-prone regions, incorporating heavy-duty stainless steel sub-frames and corrosion-resistant hardware.
Full CE Marking (EN 14351-1) for thermal performance and air tightness. For Gulf Region (GCC) projects, our doors utilize extreme temperature PVDF coatings and dual EPDM weather seals designed to block desert dust storms and withstand ambient heat exceeding 55°C without warping.
The global entrance door market is undergoing a rapid transition toward oversized pivot configurations, smart IoT access integration, and ultra-insulated low-E glazing assemblies.
Modern luxury architecture demands grand entrance scale. DERCHI leads the industry with single pivot door leaves measuring up to 2,000mm in width and 4,000mm in height. Operating on 500kg-rated concealed hydraulic floor pivots, these massive leaves open effortlessly with single-finger pressure.
Keys are rapidly becoming obsolete. Next-gen door designs integrate hidden 3D infrared biometric cameras, invisible touch-to-open sensors in pulled handles, and direct cloud API integration to notify property owners of security status and remotely manage entry permissions.
High security no longer means opaque steel slabs. Modern vision-lite doors feature bulletproof laminated triple-pane insulating glass (Argon filled, Low-E soft coated) achieving passive house U-values while withstanding sledgehammer or firearm impact threats.
Specific architectural environments require customized physical parameters. DERCHI provides tailored technical build-ups for diverse commercial and residential applications.
Primary Concern: Salt-spray oxidation, hurricane force wind-driven rain, atmospheric moisture.
DERCHI Technical Solution: 6063-T5 thermally broken profile with 30-micron PVDF fluoropolymer coating, SUS316 stainless steel hinges, marine-grade hardware, and SGP hurricane laminated double glazing certified for AS2047 N6 environments.
Primary Concern: High traffic duty cycles (100,000+ operations), acoustic isolation, emergency egress.
DERCHI Technical Solution: Oversized pivot systems fitted with German-engineered dormakaba/Geze floor springs, soundproofing acoustic core filling (reducing noise by 38dB+), and panic egress automatic multi-locking assemblies.
Primary Concern: Fire-resistance regulations, burglar anti-prying security, sound attenuation.
DERCHI Technical Solution: UL 10C / EN 1634 60-minute fire-rated armored steel-aluminum hybrid doors with perimeter intumescent seals, anti-pry hooks, and hidden biometric access sensors.
Primary Concern: Ballistic protection, explosion blast suppression, total access containment.
DERCHI Technical Solution: Custom armored bulletproof steel core overlaid with cast aluminum relief panels, NIJ III-A ballistic glazing, explosion-proof strike plates, and encrypted remote access controls.

DERCHI manufacturing systems operate under strict ISO 9001 quality management protocols. Our door platforms possess CE Marking (EN 14351-1), Australian AS2047 N6 wind/water pressure test approvals, NFRC thermal performance reports, and fire resistance test certifications (UL 10C reference). Full factory test reports, material mill certificates, and structural engineering calculations are supplied directly with quote packages for rapid local plan approval.
For standard production, leaf dimensions reach up to 1,600mm width and 3,200mm height. For custom architectural villa gates or commercial grand entrances, our engineering department designs custom heavy-duty leaves up to 2,000mm wide by 4,000mm high. These utilize internal steel box-section reinforcements and German-engineered floor pivots rated for up to 500 kg total leaf weight.
Each door leaf is wrapped in anti-scratch protective film, fitted with heavy-duty EPE foam corner armor, sealed in five-layer corrugated cartons, and fully enclosed inside a fumigation-free solid plywood crate. Frame components and hardware boxes are individually numbered according to the project door schedule, maintaining our shipping transit damage claim rate below 0.3% across more than 60 export countries.
