Precision-engineered back door systems designed for maximum durability, security, and climate adaptation. Certified to CE and AS2047 international standards.
Operating from Dali Town, Foshan—China's premier aluminum manufacturing cluster—Window Wurx Industry Co., Ltd. provides factory-direct access to raw material extrusions, thermal break technology, and advanced surface finishing.
Engineered to exact project shop drawings. We offer specialized dual-color anodizing, 60-80 micron Qualicoat powder coating, customized sash proportions, integrated pet flap cutouts, and 316 marine-grade stainless hardware.
Every back door is wrapped in protective PE film, corner-guarded, padded with high-density EPE foam, and sealed inside fumigation-free solid plywood crates, backed by container-level internal bracing.
In modern architectural procurement, the secondary exterior envelope—traditionally referred to as the aluminum back door—has evolved from a purely utilitarian service entrance into a critical vector for building thermal envelope efficiency, structural security, and smart access control. For global general contractors, real estate developers, and wholesale importers, sourcing directly from specialized manufacturers in Foshan, China, offers significant cost-to-performance optimizations when backed by stringent engineering standards.
The structural backbone of any high-durability aluminum back door relies on metallurgical selection. Standard commercial profiles typically utilize 6063-T5 aluminum alloy, offering tensile strength up to 185 MPa and yield strength of 145 MPa. This alloy provides optimal extrusion precision for intricate thermal break strip channels and multi-point lock mortises.
However, for heavy-duty security entrances and luxury villa rear gates, cast aluminum panel doors utilize high-density A356 aluminum casting alloys. These panels achieve structural thickness ranging from 8mm to 15mm, creating an impenetrable physical barrier resistant to high impact, forced entry, and mechanical shear. When combined with 6063-T6 perimeter frames, these units meet international FE (Forced Entry) resistance standards while remaining completely immune to iron oxide rust.
Aluminum exhibits an inherently high thermal conductivity ($k \approx 200 \text{ W/m}\cdot\text{K}$). Uninsulated aluminum frames act as thermal bridges, resulting in severe HVAC energy loss and interior condensation. Premium Chinese OEM manufacturers overcome this thermal bridge by implementing Isobaric Thermal Break Technology.
Commercial B2B buyers frequently require specialized functionality for back-of-house operations:
As international energy codes tighten and smart facility management expands, commercial buyers must align their procurement criteria with four major manufacturing trends shaping the Chinese export market:
Standard key cylinders are being phased out in favor of 3D facial recognition, Tuya/Zigbee smart connectivity, embedded fingerprint readers, and emergency mechanical override locks. All pre-wired inside door stiles at factory level.
Architects demand maximum natural daylight for courtyard entrances. Heavy-duty concealed pivot hinges capable of carrying 300kg+ sashes are replacing traditional butt hinges, permitting door heights exceeding 3.5 meters.
Shift toward volatile-free Fluorocarbon (PVDF) 3-coat spray finishes and water-based eco-friendly woodgrain transfer processes that resist 3,000+ hours of neutral salt spray testing (ASTM B117 compliant for coastal zones).

Detailed technical answers for importers, project management teams, and wholesale distributors regarding compliance, shipping, and OEM options.
Our window and door systems are fully tested and certified for key global markets. We carry CE certification (EN 14351-1) for the European Union and structural compliance under AS2047 and AS1288 for Australia and New Zealand. Furthermore, our insulated glass units meet SGCC (Safety Glazing Certification Council) standards for North America. Full lab test reports for wind pressure resistance (PA), water penetration, and air infiltration are provided upon project shop drawing approval.
Yes. As a factory-direct OEM/ODM manufacturer in Foshan, every aluminum back door is built-to-order according to architectural elevation plans. We support non-standard frame depths, arched tops, side lites, specialized glass build-ups, and two-tone finish configurations—allowing you to specify one color (e.g., Matt Black RAL 9005) for the exterior façade and another color (e.g., Powder White RAL 9016 or Natural Woodgrain) for the interior decor.
We utilize a heavy-duty 5-layer export packaging protocol. First, all metal surfaces are wrapped in protective non-residue PE film and fitted with plastic corner guards. Next, units are cocooned in shock-absorbing EPE foam sheet padding. The protected doors are then packed into fumigation-free, fully enclosed plywood wooden crates equipped with bottom pallet runners for forklift handling. Inside shipping containers, crates are steel-strapped and timber-braced to eliminate sea motion damage.
Standard lead times for customized aluminum back doors range from 25 to 35 calendar days following final approval of CAD shop drawings and deposit receipt. For complex custom extrusion profiles or specialized powder coating colors outside standard RAL charts, lead times may extend to 40 days. Our 20,000 m² facility with 3 automated fabrication lines allows us to maintain strict schedule adherence even on multi-container commercial development orders.
We offer flexible, cost-effective partnership programs tailored for overseas distributors, construction suppliers, and architectural dealers. Unlike restrictive franchise models, our dealer program provides direct factory pricing, exclusive geographic protection for qualified volumes, unbranded catalog collateral, technical CAD engineering support, and sample corner cutouts for your showroom. Contact our sales department to evaluate regional market availability.
We work with both premium international hardware suppliers and top-tier domestic hardware manufacturers. Options include German-engineered SIEGELIA, GU, and HOPPE systems, as well as high-precision HOPO and KIN LONG multi-point lock mechanisms. For smart electronic locks, we pre-machine mortises to house biometric fingerprint systems, RFID card readers, digital keypads, and smart home connectivity hubs (Tuya, TTLock, or Zigbee protocols).
