Request Engineering QuoteFoshan Apex Window & Door Co., Ltd. was established in 2014, operating from a state-of-the-art 35,000 m² manufacturing facility in Foshan, China—the epicenter of global architectural hardware and aluminum extrusion innovation. With over 12 years of core industry experience and 10 years of dedicated export expertise, we deliver high-performance aluminum door and window solutions globally, generating over $28 million in annual export revenue across premium international jurisdictions.
Quality control is engineered directly into every step of our manufacturing flow. Our dedicated team of 45 certified QC inspectors enforces rigid raw material incoming checks (verifying 6063-T6 aluminum alloy tensile strength and anodizing purity), ultrasonic weld seam testing, structural silicon adhesion tests, and full water-tightness pre-shipment inspections to guarantee flawless field performance. Built on a robust trade background serving global prime contractors, facade consultants, and real estate developers, our primary footprint spans North America, Oceania, and Western Europe, supported by an expansive supply network of over 1,200 reliable supply chain partners. We primarily collaborate with commercial builders, architectural design firms, and large-scale regional stocking distributors.
Driven by aggressive R&D capabilities, our engineering division includes 85 dedicated R&D engineers who launched 120 new products last year alone. We offer comprehensive, fully personalized OEM/ODM customization options, including multi-chamber thermal break profiles, smart sensor integrations, automated multi-track sliding mechanisms, and specialized architectural powder-coating finishes (AkzoNobel / PPG) designed to withstand extreme coastal C5-M corrosive environments and severe thermal expansion stresses.
The global architectural fenestration sector is undergoing a structural paradigm shift driven by stringent municipal energy codes, ESG mandates, and the acceleration of Net-Zero Building (NZB) standards worldwide. Enterprise buyers, general contractors, and commercial developers no longer evaluate aluminum glazed window suppliers based solely on initial capital expenditure per square meter. Modern structural procurement is defined by holistic performance lifecycle metrics: U-Factor optimization, Solar Heat Gain Coefficient (SHGC), Sound Transmission Class (STC), and life-cycle embodied carbon reduction.
Integration of multi-chamber polyamide thermal barriers (PA66GF25) reducing thermal bridge conductance to achieve U-values below 0.8 W/m²K, essential for Passive House standards.
Demands for laminated SentryGlas® interlayers and reinforced structural frames rated for Florida Dade County hurricane impact and 6000 Pa wind load testing.
Urban density growth requires multi-layer glass assemblies with asymmetric glass thickness combinations and Argon/Krypton gas infills to achieve STC ratings above 45dB.
As a premier **China Top Aluminium Glazed Window Supplier**, Foshan Apex addresses these macroscopic structural demands by fusing high-precision Chinese extrusion technologies with rigorous global engineering certifications. By operating directly out of Foshan's deep industrial supply chain ecosystem, we provide high-volume commercial projects with custom unitized curtain wall systems, thermal break sliding doors, and architectural bi-fold windows at a fraction of Western manufacturing lead times and costs.
Every fenestration unit undergoes rigorous automated fabrication and multi-stage quality control within our 35,000 m² facility.
To assist architectural engineers, specifiers, and procurement officers in technical evaluation, the following matrix outlines our standard engineering parameters across our primary product categories:

| Thermal Transmittance (U-Value) | 1.2 - 1.8 W/m²K (Low-E + Argon) | 1.4 - 2.0 W/m²K | 0.9 - 1.4 W/m²K (Triple Glazed) |
| Acoustic Insulation Rating | STC 38dB - 42dB | STC 40dB - 48dB (Laminated PVB) | STC 35dB - 40dB |
| Wind Pressure Resistance | Class 8 (3500 Pa) | Class 9 (6000 Pa / ASTM E1300) | Class 8 (4000 Pa) |
| Water Tightness Performance | Class 6 (600 Pa) | Class 8 (900 Pa) | Class 7 (750 Pa) |
| Hardware & Seal Systems | German SIEGENIA / HOPO Multi-point | Custom Stainless 316 Anti-Corrosive | EPDM Continuous Dual-DENSITY Gaskets |
Navigating international building codes is a critical capability for global Fenestration procurement. Foshan Apex maintains stringent international compliance certifications, mitigating import risk for developers, contractors, and local distributors.
Fully tested and certified under **NFRC** (National Fenestration Rating Council) and **CSA** standards. Designed to meet energy ratings required by Title 24 in California and ASTM E1886/E1996 hurricane impact standards for coastal states.
Compliant with **CE EN 14351-1** structural and thermal safety directives. Multi-chamber thermal profiles engineered to align with Passive House Low-Energy requirements across Western Europe.
Rigorously tested according to **AS2047** and **AS1288** Australian standards, ensuring proper deflection ratings, water penetration resistance, and compliance with WERS energy ratings.
Our dedicated logistics department handles comprehensive export documentation, custom heavy-duty wood-crate packing, steel-frame container consolidation, and optional DDP (Delivered Duty Paid) door-to-site shipping. From blueprinted structural shop drawings (CAD/BIM) to final jobsite unloading, Foshan Apex provides seamless end-to-end operational security.

Foshan Apex offers a unique combination of scale, technical expertise, and rigorous quality control. Operating a 35,000 m² facility with 85 R&D engineers and 45 QC inspectors, we export over $28M annually. Our products are fully certified under NFRC, CSA, CE, and ISO standards, ensuring seamless integration into major Western commercial and residential projects without compliance friction.
Standard aluminum frames conduct heat easily, leading to thermal loss and condensation. Thermally broken aluminum windows incorporate a low-conductive polyamide strip (PA66GF25) separating the interior and exterior aluminum extrusions. This structural break dramatically reduces U-Factors, prevents interior condensation, and boosts energy savings by up to 40% in harsh climates.
Our NFRC and CSA certified series utilize warm-edge spacers, multi-layer Low-E coatings (double or triple silver sputtering), and high-purity Argon gas infills. Frame designs feature multi-chamber thermal barriers and structural EPDM seals to consistently hit target U-Factors under 0.30 BTU/h·ft²·°F and low SHGC values required by North American energy codes.
Our 85 R&D engineers offer complete CAD/BIM shop drawing development, structural wind-load calculation, glass stress analysis, and custom extrusions. We assist developers and architects from pre-construction design phases through mock-up testing and final jobsite installation guidance.
Standard custom fabrication lead time ranges between 25 to 35 business days from final shop drawing sign-off. With our 35,000 m² factory footprint and automated CNC cutting and weaving machinery, we produce over 30,000 square meters of high-performance fenestration per month, ensuring reliable supply chain schedules for multi-family and commercial developments.
Our hurricane impact sliding doors and fixed windows feature laminated safety glass paired with PVB or DuPont SentryGlas® (SGP) interlayers. In the event of extreme impact, the glass shatters without detaching from the frame, maintaining envelope integrity under wind loads up to 6000 Pa, adhering strictly to ASTM hurricane testing criteria.
