Engineered to deliver exceptional thermal insulation ($U_w \le 1.0 \text{ W/m}^2\text{K}$), storm windproof rating, and modern slimline aesthetics for Belgian residential and commercial projects.
The Kingdom of Belgium represents one of Western Europe's most rigorous and demanding markets for exterior fenestration products. Characterized by a maritime temperate climate with high frequency of rainfall, strong North Sea coastal wind vectors, and substantial winter humidity, the construction sector across Flanders, Wallonia, and the Brussels-Capital Region demands highly durable, thermally decoupled building envelope components.
Modern Belgian architectural trends emphasize seamlessly transitioning indoor living spaces to outdoor gardens, terraces, and urban courtyards. Aluminum bifold doors (also known as folding glass doors or accordion patio doors) have emerged as the premier architectural choice over traditional sliding patio systems for high-end residential renovation in Ghent and Antwerp, luxury seaside villas in Knokke-Heist, and contemporary urban infill developments in Brussels.
Belgium’s regional building codes—governed by EPB (Energieprestatie en Binnenklimaat) regulations—mandate strict overall thermal transmittance thresholds ($U_w$) for building envelopes. To comply with modern Belgian NBN EN standards, exterior bifold systems must deliver superior thermal isolation. Shenzhen Astris Window & Door Technology Co., Ltd. incorporates multi-chamber polyamide thermal break strips (PA66GF25) and advanced warm-edge spacer technology, allowing our custom bifold systems to achieve overall $U_w$ values as low as $0.95 \text{ W/m}^2\text{K}$ when fitted with triple-pane argon-filled Low-E glass assemblies.
Belgian weather conditions, particularly in coastal West Flanders and exposed elevation sites, demand fenestration systems capable of resisting extreme wind pressure and driving rain. Our structural aluminum profiles (utilizing 6063-T6 aluminum alloy with dynamic wall thickness ranging from 2.0mm to 3.0mm) are paired with multi-layer continuous EPDM synthetic rubber gaskets. Certified under EN 12208 (Water Tightness Class E1050) and EN 12210 (Wind Load Resistance Class C5), Astris bifold doors ensure complete weatherproofing under harsh European autumn storms.
Built upon precision engineering, scalable manufacturing, and direct compliance with European architectural standards.
Features 24mm to 34mm PA66GF25 structural nylon thermal breaks integrated between extruded high-tensile 6063-T6 aluminum frames, virtually eliminating thermal bridging and condensation in cold Belgian winters.
Engineered for urban noise reduction in high-density European cities like Brussels and Liege. Dual or triple acoustic laminated glass configurations damp ambient traffic noise to maintain interior tranquility.
Surface treatments resistant to UV degradation and salt mist corrosion. Available in full RAL color spectrums including Belgian favorite finishes: RAL 7016 Anthracite Grey, RAL 9005 Jet Black, and RAL 9016 Traffic White.
Certified engineering data tailored for Belgian architectural specifications and building code verifications.

Streamlining global supply chain logistics, direct OEM/ODM customization, and localized architectural compliance.
Astris provides large-span exterior bifold systems configured for high foot-traffic hospitality setups, restaurant terraces, and luxury commercial complexes. Featuring flush zero-threshold tracks (barrier-free PRM accessible complying with European accessibility guidelines), high acoustic isolation, and heavy-duty bottom-hung stainless steel rollers rated for up to 400kg panel loads.
We empower Belgian importers, window distributors, and trade installers with fully customized OEM profile extrusions, knock-down (KD) packaging for optimized sea-container payload factor, and complete technical CAD/BIM drawing support. Partnering directly with our factory yields 30-45% cost efficiency compared to local Western European assembly systems.
Combining modern industrial manufacturing automation with rigorous quality control testing.
Founded in 2013, Shenzhen Astris Window & Door Technology Co., Ltd. operates a modern, state-of-the-art production complex covering 28,000 square meters. Leveraging 13 years of deep technical expertise in structural aluminum engineering and 9 years of direct international trade experience, our facility generates over $35 million in annual export revenue across premier markets in Western Europe, North America, and Australia.
Quality assurance is guaranteed by our in-house team of 45 certified Quality Control (QC) technicians who execute stringent testing protocols, including accelerated salt spray corrosion testing (ASTM B117 compliance), glass impact testing, thermal camera insulation scanning, and structural corner seam tension stress evaluations. Supported by a robust network of over 800 supply chain partners, Astris provides limitless customization possibilities: customized RAL powder coating, specialized anodizing, integrated motorized blinds, heavy-duty multi-point locking mechanisms, and triple-glazed energy efficient glass panels. Our 50 R&D engineering specialists successfully designed and launched 60 brand-new architectural window and door systems last year alone.
From raw aluminum extrusions to final commissioned bifold doors ready for shipment to the Port of Antwerp.
