Precision-engineered fenestration solutions certified to international thermal, structural, and acoustic compliance standards.
In contemporary architectural design, the boundary between indoor living spaces and external environments has evolved from a simple functional barrier into a fluid design canvas. **CE Certified Aluminium Folding Glass Doors** (commonly designated as bi-fold glass doors, folding patio doors, or concertina door systems) serve as the cornerstone for modern residential luxury villas, high-end commercial hospitality developments, and sustainable urban extensions.
As a verified manufacturer and global exporter operating from Foshan, China—the world's preeminent hub for architectural aluminium profile processing—**Window Wurx Industry Co., Ltd.** delivers precision-engineered folding glass door assemblies built strictly according to European Union Standard **EN 14351-1:2006+A2:2016** (Windows and doors - Product standard, performance characteristics). CE certification is not merely a regulatory stamp; it provides rigorous, third-party benchmarked proof covering structural wind load resistance, air permeability, water tightness, thermal insulation parameters (U-values), and mechanical durability over tens of thousands of opening cycles.
Equipped with heavy-duty bottom-hung quad-roller assemblies constructed from SUS304 stainless steel bearings, supporting panel weight capacities of up to 150 kg per leaf without structural noise or track friction.
Engineered with concealed shoot-bolt locking mechanisms operating at top and bottom track points, integrated with European profile anti-snap lock cylinders meeting EN 1303 security ratings.
Multi-chambered profile geometry supporting double (5mm+12Ar+5mm) or triple insulated glass units (IGU) with argon gas filling, reducing noise transmission by up to STC 42 dB.
For international commercial procurement directors, real estate developers, and wholesale distributors, sourcing fenestration products from Chinese manufacturers requires understanding macro architectural shifts. Based on global building code updates (such as the EU Energy Performance of Buildings Directive and Australia's NCC 2022 climate requirements), sourcing priorities have shifted from initial unit cost to **whole-lifecycle thermal efficiency, material circularity, and supply chain transparency**.

Founded in **1993**, Window Wurx Industry Co., Ltd. has established itself over 30+ years as a leading OEM/ODM manufacturer and exporter of custom aluminium windows, doors, skylights, sunrooms, and curtain wall systems. Situated in Foshan City, Guangdong Province, our factory spans an expansive **20,000 square meter automated production facility** powered by over 150 skilled fabricators, experienced structural engineers, and dedicated quality assurance specialists.
We operate **three fully automated German CNC extrusion and cutting production lines**, enabling millimetric precision during profile mitering, corner crimping, and hardware mortising. This advanced automation guarantees consistent quality whether executing a custom single-villa project or supplying container loads for large-scale multi-building commercial developments.
We provide comprehensive custom design flexibility, offering dual-color powder coating (PVDF), anodizing, and real woodgrain heat-transfer finishes. Specify internal frame colors to match indoor decor while maintaining external facade color schemes.
International ocean freight demands robust packing standards. Every unit undergoes a 5-layer packing process: protective surface film, EPDM corner guards, bubble wrap, shock-absorbing cardboard, and sea-freight compliant fumigation-free wooden crates.
With active export channels across Europe, North America, Australia, New Zealand, and the Middle East, our technical teams possess deep expertise in regional building codes (CE, AS2047, NFRC, CSA), streamlining your import customs clearance.
Our aluminium folding door systems are fully certified under EU Standard EN 14351-1:2006+A2:2016. Factory production control (FPC) procedures ensure that air permeability, watertightness, structural wind resistance, and thermal transmittance values comply with European Construction Products Regulation (CPR 305/2011). Full test reports from accredited laboratories are provided alongside official Declarations of Performance (DoP).
For large-opening bi-fold installations (e.g., individual sash heights exceeding 3000mm or total width exceeding 10 meters), we utilize heavy-duty 6063-T6 aluminium structural profiles featuring internal steel or aluminium reinforcing mullions. Additionally, bottom-hung weight-bearing guide tracks shift panel loads directly onto the floor structure, preventing top lintel deflection and tracking jams.
Yes. Every door panel is built to custom order drawings. For noise-sensitive urban settings, we integrate laminated sound-control glass (e.g., 6mm Low-E + 1.52PVB + 6mm Clear IGU) achieving up to STC 42 dB sound attenuation. For storm or hurricane-prone coastal regions, we supply high-impact SentryGlas (SGP) laminated glass units tested for severe wind-borne debris protection.
We offer both top-tier domestic hardware and premium European hardware systems, including Siegenia, Hoppe, and custom Window Wurx heavy-duty stainless steel mechanisms. All exterior hardware components undergo rigorous 500-hour neutral salt spray testing (ISO 9227), making them suitable for severe coastal environment corrosion conditions.
Standard custom fabrication lead time ranges between 25 to 35 calendar days following shop drawing approval and color sample sign-off. Products are fully assembled and tested for smooth operation in our workshop prior to dismantling into serialized export packaging. Container loading is conducted using dedicated ramps and internal bracing systems to eliminate transit shifting during ocean transport.
We provide complete technical support, including BIM/CAD shop drawing creation, engineering calculations, structural wind-load simulations, and physical sample kits. Our global dealer partnership model offers factory-direct pricing without restrictive franchise fees, supported by dedicated English-speaking technical sales managers.
