Explore our export-certified aluminum system solutions tailored for residential towers, commercial developments, coastal luxury villas, and mixed-use complexes.
In-depth technical analysis for facade consultants, structural engineers, and global commercial project contractors specifying extruded aluminium assemblies.
Custom OEM Aluminium Ke Doors manufactured at our Foshan facility utilize primary architectural billet alloys compliant with 6063-T5, 6063-T6, and 6061-T6 standards. Unlike secondary recycled scrap that compromises tensile integrity, our profiles ensure yield strengths exceeding 160 MPa and ultimate tensile strengths above 205 MPa. This structural rigidity allows our Ke Doors (engineered key entrance doors and integrated structural pivot/hinged entrance systems) to support leaf dimensions exceeding 3,500 mm in height and 2,000 mm in width without flex deflection under high mechanical loads.
In high-wind and severe weather corridors—such as typhoon-prone coastal regions across Southeast Asia, North America, and the Caribbean—our assemblies incorporate internal steel stiffener reinforcements and multi-point mortise locking gear that easily surpass AS 2047 N6 cyclonic ratings (structural deflection resistance up to 4,500 Pa and water penetration resistance up to 700 Pa).
| Performance Parameter | Industry Standard Target | DERCHI OEM Aluminium Ke Door Spec | Validation / Test Method |
|---|---|---|---|
| Aluminium Alloy Profile | GB 5237 / ASTM B221 | 6063-T6 Primary Extrusion (2.0mm - 3.5mm wall) | Spectrometric Chemical Analysis |
| Wind Pressure Resistance | Class 4 (≥ 2.5 kPa) | Class 8 / AS 2047 N6 (≥ 4.5 kPa to 5.0 kPa) | ASTM E330 / AS 4420.2 |
| Thermal Transmittance (U-Factor) | 2.8 - 3.5 W/(m²·K) | 1.2 - 1.8 W/(m²·K) (Multi-Cavity PA66 Break) | NFRC 100 / ISO 10077-2 |
| Acoustic Isolation (STC/Rw) | Rw 28 - 32 dB | Rw 38 - 44 dB (Laminated Acoustic IGU) | ASTM E90 / ISO 717-1 |
| Surface Corrosion Resistance | AAMA 2603 (500 hrs salt spray) | AAMA 2605 / Qualicoat Class 2 (≥ 3,000 hrs) | ASTM B117 Neutral Salt Spray |
Thermal separation is achieved via precision knurled crimping of polyamide PA66 GF25 (25% glass fiber reinforced) structural thermal break barriers. This breaks conductive bridge pathways, preventing internal condensation in humid, air-conditioned hospitality projects while drastically lowering total solar heat gain coefficient (SHGC) values to as low as 0.22.
Direct supply from Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) eliminates middle-tier broker markups while securing Tier-1 manufacturing consistency.
Equipped with computerized 5-axis CNC machining stations, automatic sealant injection lines, and dust-free robotic powder coating booths, ensuring 100% mechanical alignment and defect-free finishes.
Complete project documentation packages for CE, AS 2047, ISO 9001, and UL fire ratings. Tested rigorously to meet strict municipal building codes across the Americas, Australasia, and Southeast Asia.
Free shop drawing generation (BIM & CAD) to fit scheduled structural openings. Customized profile shapes, integrated smart motorized locks, custom cast handles, and specialized glass configurations.
Direct English-speaking engineering sales consultants operating across GMT+8 with rapid 24-hour drawing turnarounds, real-time video workshop audits, and live factory tracking.
Strategic purchasing guidance for institutional buyers navigating decarbonization mandates, smart home integration, and aesthetic shifts over the next 5 to 10 years.
Commercial building ratings such as LEED v4.1 and BREEAM are requiring low-embodied-carbon aluminium extrusions. Modern procurement focuses on verified hydro-powered smelting and high-percentage post-consumer recycled billets accompanied by Environmental Product Declarations (EPDs).
The traditional mechanical mortise lock is rapidly evolving into integrated biometric concealed hardware. Next-generation custom aluminium Ke doors embed face-recognition sensors, hidden motorized multipoint latches, and wireless building management system (BMS) relays directly into the thermal break cavities.
Architects demand maximum glass-to-frame ratios. Structural engineering allows 20mm ultra-narrow interlocking stiles capable of carrying 800 kg insulated glass units with whisper-quiet, concealed bottom magnetic levitation or heavy-duty bearing wheel mechanisms.
The global aluminium door manufacturing landscape is transitioning from single-material fabrication to multi-material hybrid systems. Modern luxury villa entrance Ke doors and commercial entrance portals combine fluoropolymer PVDF-coated exterior extrusions with cast aluminium 3D relief panels, internal bullet-resistant composite plates, and acoustic ceramic thermal isolators.
Furthermore, vacuum-insulated glass (VIG) technology is actively displacing conventional double-glazed units in high-end projects, dropping Center of Glass (Cog) U-values below 0.60 W/(m²·K) without increasing door leaf mass. As an agile OEM exporter, DERCHI maintains proprietary tooling and CNC pathways to implement these high-value innovations rapidly into client specifications.
Critical considerations regarding lead times, logistics, quality compliance, and custom fabrication addressed by our technical team.
Standard OEM extrusion and assembly lead times typically span 25 to 35 working days following final shop drawing and sample finish sign-off. For complex projects requiring custom tooling dies or specialized smart glass lamination, our engineering division offers accelerated phased shipment schedules.
For installations within 5 km of coastlines, we specify AkzoNobel or PPG certified fluorocarbon PVDF finishes (minimum 3-coat system conforming to AAMA 2605) or marine-grade anodizing (Class 1, 25-micron thickness), coupled with AISI 316 stainless steel hinges, rollers, and lock cases.
Yes. Our heavy-duty hydraulic floor spring pivot systems and tandem stainless steel wheel carriages support single leaf weights up to 1,000 kg and clear opening heights reaching 4.5 meters, engineered with internal wind load deflection channels verified by structural FEA modeling.
All finished units are wrapped in peelable protective film, cushioned with multi-layer high-density EPE foam corner protectors, strapped with heavy-duty tension belts, and enclosed within IPPC-certified fumigated fully enclosed plywood shipping crates with integrated moisture desiccants.
We provide full, unredacted third-party test reports issued by ILAC-MRA accredited laboratories (such as Intertek, TÜV, and Win-Test) detailing test results for AS 2047, CE EN 14351-1, and NFRC thermal ratings alongside factory ISO 9001 quality compliance dossiers.
For standard architectural profiles in our catalog, our MOQ is flexible (starting at 1 complete unit for luxury bespoke estates). For completely customized proprietary extrusion dies, an initial trial run of 500 kg to 1 ton is typical, with mold tooling costs fully rebated upon reaching target container volumes.
