Headquartered in Foshan — China’s world-renowned aluminum and fenestration production capital. For over 25 years, Derki has been an industry leader delivering vertically integrated research, engineering, and manufacturing of premium aluminum entry doors, cast aluminum pivot main gates, interior wooden doors, and automated garage systems.
OEM/ODM Technical Authority Guarantee: Unlike trading companies, Guangdong Derki operates automated CNC double-head cutting systems, high-tonnage hydraulic casting presses, and automated powder coating lines in-house. We provide free CAD shop drawings, structural wind-load calculation submittals, and full material traceability for international project tenders.
Understanding the technical parameters that distinguish high-end custom aluminum entry doors from standard residential fenestration.
Our structural aluminum door frames utilize primary high-purity 6063-T5/T6 aluminum alloy with profile wall thicknesses ranging from 2.0mm to 3.5mm. This delivers exceptional tensile strength (up to 205 MPa) capable of supporting oversized 500kg+ pivot door panels without structural deflection.
To eliminate cold bridging and reduce thermal conductivity, our thermal break entry doors incorporate 25% glass fiber reinforced Polyamide 66 (PA66-GF25) thermal insulation strips. This achieves overall entrance assembly U-factors as low as 1.1 W/m²K, surpassing strict energy codes.
Surface treatments are critical for long-term weatherability. We apply AkzoNobel PVDF (Fluorocarbon) coatings and heavy architectural anodizing that endure 3,000+ hours of continuous salt-spray testing, preventing chalking, fading, and oxidation in coastal environments.
Key shifts driven by modern architecture, decarbonization mandates, and smart building integration reshaping the global B2B door sourcing landscape.
Modern luxury residential design is abandoning traditional standard-sized swing doors in favor of oversized pivot entrance systems reaching heights up to 4.5 meters and widths up to 2.2 meters. Architects demand heavy-duty concealed offset pivot hinges (such as German DormaKaba or Dutch FritsJurgens systems) integrated into rigid thermal break aluminum structures capable of smooth finger-touch operation.
Mechanical lock keys are rapidly giving way to motorized multi-point electronic locking systems. Procurement requirements now routinely specify pre-wired factory integration for 3D facial recognition, palm vein scanners, biometrics, and IoT protocols (Zigbee, Z-Wave, KNX). Modern entry doors must act as secure digital gateways for smart home ecosystems.
Global climate volatility has accelerated code enforcement for impact-rated fenestration. Importers across Australia, the Caribbean, North America, and coastal Asia now mandate structural certifications like Australia's AS2047 (N6 rating, supporting up to 4500 Pa wind pressures) and UL fire-rated submittals to pass municipal building sign-offs.
To combine structural strength with artistic distinction, luxury villa developments are adopting composite door designs. These fuse deep 3D relief cast aluminum exterior faces (providing zero-rust durability and high security) with interior real solid wood veneers and polyurethane insulation cores.

Designed for overseas developers, general contractors, and importers who require absolute precision, timeline compliance, and zero site modifications.
Send your architectural door schedule or elevation drawings. Our English-speaking engineering team prepares full CAD shop drawings detailing opening directions, wall jamb sections, and hardware cutouts within 24 hours.
We calculate wind pressure loads, thermal requirements, and structural panel weights to recommend the ideal aluminum profile thickness, glass build-up, and lock hardware (DormaKaba, Hoppe, or smart electronic systems).
Aluminum profiles are cut, milled, and corner-crimped using automated CNC machining centers in our 180,000 m² Foshan facility, ensuring dimensional tolerances within ±0.5mm.
Panels undergo multi-stage chemical pre-treatment followed by AkzoNobel PVDF fluorocarbon spraying or vacuum heat transfer wood-grain sublimation for maximum UV resistance.
Every custom entry door is 100% pre-assembled in the factory. Locks, hinges, weatherstripping, and glass units are fitted and cycle-tested prior to final inspection sign-off.
Doors are wrapped with protective film, corner guards, and sealed inside fully enclosed export plywood crates. We supply clear installation manuals and remote engineering video support for site installation.
Clear engineering answers regarding OEM specs, international codes, lead times, and structural options.
Guangdong Derki specializes in high-end architectural entry systems including thermal break aluminum pivot doors, cast aluminum 3D relief main entrance gates, stainless steel armored security doors, narrow-frame glass entrance doors, and solid core interior wooden doors. All products are fully customizable in dimensions, profile alloy, finish, glass specification, and hardware lock configuration.
Our entry door systems are engineered and tested to comply with major global codes. We hold CE certificates for European compliance, ISO 9001 quality management system certification, Australia AS2047 (reaching the highest N6 structural wind load and water tightness rating), and UL fire-rated assembly certifications for North American projects. Complete official test reports can be provided for municipal inspection submittals.
Yes. Oversized architectural pivot doors are one of our core OEM specialties. Utilizing heavy-duty reinforced 6063-T6 aluminum profiles and German floor-pivot spring systems, we custom fabricate pivot panels up to 4.5 meters in height and up to 1,000 kg in weight with smooth, effortless operation and complete weather sealing.
For coastal installations (such as beach house villas or island resort projects), we recommend our anodized or AkzoNobel PVDF (fluorocarbon powder coating) aluminum profiles combined with 304/316 grade stainless steel hardware. These finishes undergo 3,000+ hours of continuous salt-spray corrosion testing, preventing oxidation, pitting, or surface degradation over decades of exposure.
Our standard production lead time is 25 to 35 days following CAD drawing approval and deposit receipt. For ocean shipping protection, every door panel is wrapped with anti-scratch protective film, fitted with heavy rubber corner protectors, encased in moisture-proof plastic wrap, and packed inside fumigation-free, reinforced plywood crates designed for fork-lift handling.
Absolutely. Every custom door order includes comprehensive CAD shop drawings prepared by our engineering department free of charge. These drawings specify exact structural dimensions, frame profile sections, wall anchoring details, glass cross-sections, and lock hardware positions for architect and client approval before any cutting begins.
Yes. Our engineering team routinely integrates smart access hardware into our custom aluminum entry doors. We can factory pre-wire electric strike locks, motorized multi-point latches, 3D facial recognition units, fingerprint scanners, and keypad systems compatible with home automation protocols (KNX, Zigbee, Z-Wave, Control4).
We stand firmly behind our engineering quality. Derki provides a 10-year structural warranty on extruded aluminum profiles and cast aluminum panels, a 10-year warranty on PVDF/anodized surface finishes against discoloration, and a 5-year warranty on mechanical locks and pivot hardware components.
