Precision-extruded aluminum fenestration products manufactured under CE & AS2047 international compliance frameworks.
Founded in 1993, Window Wurx Industry Co., Ltd. operates as a premier OEM/ODM manufacturer located in Dali Town, Nanhai District, Foshan—the epicenter of China's structural aluminum extrusion industry. Over three decades of fenestration refinement have positioned our factory as a dependable global exporter for commercial contractors, facade architects, and regional window distributors.
Spanning a modern 20,000-square-meter workshop equipped with CNC profile machining centers and automated corner-crimping lines, our facility maintains a monthly throughput capacity exceeding 35,000 square meters of high-performance exterior aluminum storm windows and architectural door systems.
A rigorous breakdown of structural load resistance, thermal isolation physics, and severe weather sealing mechanisms.
Exterior storm windows serve as the primary defensive shield against high wind velocity, driven wind-rain, and impact debris. The structural backbone of China's top-tier storm windows lies in extruded 6063-T5 or T6 grade aluminum alloys. Unlike standard residential window profiles with wall thicknesses hovering around 1.2mm, high-load storm windows utilize heavy-duty wall profiles ranging from 1.8mm to 3.0mm.
The profile geometry incorporates webbed internal multi-chamber strengthening ribs. These internal chambers disperse localized impact energy across the structural frame, preventing permanent frame deflection during severe storm events (such as Category 4 and 5 hurricanes or cyclonic gales).
Historically, aluminum storm windows suffered from thermal bridging due to aluminum's high thermal conductivity (~200 W/m·K). Modern manufacturing solves this by inserting continuous 24mm to 34mm Polyamide PA66 reinforced with 25% glass fiber (PA66-GF25) thermal barrier strips.
This mechanical break decouples the interior and exterior aluminum profiles, reducing overall fenestration U-factors to values as low as 1.1 to 1.4 W/m²K (when paired with double-pane Low-E insulated glass units). Furthermore, this separation enables Dual-Color Anodizing & Powder Coating, allowing architects to specify dark fluorocarbon exterior finishes (such as Matt Black or Bronze) while maintaining neutral white or interior timber-grain textures indoors.
Storm window glazing relies on multi-layer composite glass assemblies. High-velocity hurricane zones (HVHZ) mandate laminated toughened glass configurations—typically composed of 6mm tempered outer pane + 1.52mm PVB/SGP structural interlayer + 6mm tempered inner pane.
When combined with an insulating argon gas chamber and soft-coat Low-E solar control films, the window achieves superior Solar Heat Gain Coefficients (SHGC < 0.23) while dampening external sound pressures by up to STC 42 - 45 dB.

Key technological transformations shaping overseas buyers' supply chain strategies when importing aluminum windows from China.
Global commercial construction is moving rapidly toward off-site prefabrication. Overseas buyers increasingly request fully unitized storm window wall sub-assemblies with pre-installed anchor brackets, enabling fast job-site installation and drastically reducing domestic labor overheads.
Driven by EU CBAM carbon tariffs and LEED green building standards, top Chinese factories are adopting hydro-powered, recycled 6063 aluminum billets. Sourcing low-embedded-carbon aluminum reduces scope 3 carbon footprints without compromising tensile yield strength.
Modern architectural aesthetics demand clean sightlines. Next-generation storm windows feature fully concealed European groove hinges and automated electronic multi-point lock actuators integrated into building automation systems (BAS).
Future-proof exterior storm windows are transitioning into energy generators and dynamic light regulators. Smart dynamic glass (smart tinting) and Building-Integrated Photovoltaics (BIPV) embedded in spandrel storm panels represent the next frontier in commercial glazing.
With increasing frequency of extreme climate events worldwide, international importers are seeking products certified for extreme wind-borne debris impact (such as ASTM E1886/E1996 and Australian AS1170.2 cyclonic standards) directly from Chinese production lines.
For coastal and resort developments, demand has shifted toward 70% PVDF fluorocarbon coatings tested to withstand 4,000+ hours of continuous salt spray exposure, preventing filiform corrosion in high-salinity marine environments.
International ocean transport subjects heavy aluminum fenestration products to high vibration, humidity, and mechanical impact. Window Wurx enforces a strict 5-layer protective packing protocol to guarantee zero-defect arrival on site.
Direct export capabilities serving contractors and dealers across North America, Australia, Europe, and the Middle East.
Comprehensive answers addressing regulatory compliance, customization specs, and international factory logistics.
Our window and door systems are fully certified for major global markets. We hold CE certification (EN 14351-1) for European Union construction standards and AS2047 / AS1288 certification verified by independent Australian testing laboratories (covering air infiltration, water penetration resistance, and ultimate strength load tests up to 6000 Pa). Furthermore, selected thermal-break systems feature NFRC energy ratings and Florida Building Code HVHZ impact certifications. Complete factory test reports and mill certificates are made available during project quotation.
Yes, 100% of our production is engineered-to-order based on structural shop drawings. You can customize profile frame depth (e.g., 65mm, 75mm, 110mm, 135mm series), aluminum wall thickness (1.4mm to 3.0mm), thermal barrier width, glass configurations (double/triple pane, laminated, smart tint, Low-E coatings), and hardware systems. We regularly integrate premium European hardware brands such as CMECH, SIEGENIA, HOppe, and ROTO alongside our high-durability proprietary factory hardware.
Standard aluminum storm windows use uninsulated solid metal profiles, which readily conduct outside cold or solar heat into the interior building envelope. Thermal-break storm windows feature an engineered structural separation where the outer and inner aluminum profiles are joined together by low-conductivity PA66-GF25 polyamide nylon strips. This mechanical break blocks heat transfer, eliminates frame condensation, significantly lowers HVAC energy consumption, and prevents interior frame frost in extreme cold climates.
Operating our own vertical powder-coating and anodizing lines allows us to produce custom RAL color matching, AkzoNobel powder coatings, anodized silver/bronze finishes, and realistic architectural wood-grain textures. Because we assemble our thermal-break profiles in-house, we can easily furnish dual-color (two-tone) windows—enabling a weather-resistant fluorocarbon dark finish on the external facade side while matching interior timber or light painted decor indoors.
Standard production lead times range between 25 to 35 calendar days following the final approval of CAD shop drawings and deposit confirmation. For custom extruded dies or specialized glass laminated builds, lead times may extend to 40 days. Our 20,000 m² facility and 3 automated assembly lines enable reliable delivery scheduling for both single luxury villa packages and multi-story commercial window replacement projects.
Every single unit undergoes a strict 5-layer protective packing sequence: anti-scratch film, EPE foam corner protectors, vacuum moisture sealing film, heavy corrugated edge guards, and solid fumigation-free plywood crates. Inside shipping containers, crates are steel-strapped and braced with shock-absorbing air bags to prevent movement caused by ocean turbulence and container handling.
