Austria’s architectural landscape demands fenestration products that effortlessly balance extreme environmental durability with refined visual minimalism. From the dense urban topography of Vienna and Graz to the high-altitude, freeze-thaw cycles of Tyrol, Salzburg, and Vorarlberg, imported architectural window systems face complex structural and thermal challenges.
As a specialized manufacturer and global exporter of high-spec aluminium window systems, our factory delivers tailor-made fenestration solutions engineered strictly to European standards (EN 14351-1) and localized Austrian building guidelines (ÖNORM B 5320). Anthracite Grey (RAL 7016)—particularly in fine-texture (Feinstruktur) and architectural matte finishes—has established itself as the dominant exterior aesthetic across contemporary residential and commercial construction in Austria. Below is a comprehensive breakdown of the technical mechanics, structural specifications, and regulatory compliance considerations governing our direct export program for Austrian buyers.
Austrian building regulations (OIB Richtlinie 6) mandate strict total window U-values ($U_w$). Our thermal-break aluminium frames utilize high-precision Polyamide PA66-GF25 glass-fiber reinforced insulating strips, combined with multi-chamber internal geometry and Swisspacer Ultimate warm-edge spacers, achieving whole-window values down to $0.78 \text{ W/m}^2\text{K}$.
High-altitude UV exposure in alpine regions accelerates thermal expansion and surface degradation. We utilize Qualicoat Class 2 architectural powder coatings. The RAL 7016 fine-texture finish provides superior scratch resistance, repels dirt buildup, and minimizes frame surface temperature buildup during peak summer irradiance.
In accordance with Austrian fenestration preferences, our casement series integrates heavy-duty European Groove (Euro-Groove) concealed hardware (Siegenia / Roto origin compatibility). This allows dual-action operation: micro-ventilation tilting for controlled air exchange and 90°/180° inward turning for safe interior cleaning.
When sourcing aluminium windows directly from a Chinese OEM/ODM factory, technical clarity is essential. The table below outlines our core profile systems engineered for Austrian residential and commercial imports:
| System Designation | Profile Depth & Alloy | Thermal Break Tech | Glazing Specification | Max Wind Load (EN 12210) | Target Local Application |
|---|---|---|---|---|---|
| AT-75 Passiv Series | 75mm / 6063-T6 (1.8-2.0mm) | 34mm PA66-GF25 + Aerogel | 48mm Triple (4-18Ar-4-18Ar-4 Low-E) | Class C5 (2000 Pa) | High-Altitude Chalets & Passivhaus Austria |
| AT-68 Urban Tilt & Turn | 68mm / 6063-T5 (1.6mm) | 24mm Multi-Chamber Strip | 36mm Double/Triple Insulated | Class C4 (1600 Pa) | Vienna Altbau & Neubau Residential |
| LS-150 Lift & Slide Door | 150mm Track / 6063-T6 (2.2mm) | Polyamide Heavy Duty Break | 40mm Toughened Triple Safety Glass | Class B5 (1800 Pa) | Panoramic Patio & Balcony Entrances |
| FW-50 Architectural Fixed | 50mm Slim Sightline Profile | Continuous Isolator Block | 52mm Laminated Low-E Triple IGU | Class C5 (2400 Pa) | Commercial Facades & Modern Villas |
The Challenge: Extreme winter sub-zero temperatures, heavy snow-load accumulation, and high wind pressures on elevated slopes in regions like Kitzbühel and Innsbruck.
Our Solution: Heavy-wall 6063-T6 profiles coupled with triple-pane laminated safety glass (featuring double soft-coat Low-E argon gas fills). The Anthracite RAL 7016 matte surface pairs naturally with traditional wood and stone architectural elements while ensuring continuous air permeability resistance (EN 12207 Class 4).
The Challenge: Retrofitting urban residential buildings (*Neubau* projects and *Sanierungsbonus* energy retrofits) where space optimization and high acoustic insulation against street noise are critical.
Our Solution: Flush interior-exterior sash profiles with ultra-slim sightlines. Soundproof acoustic laminates achieve up to 45dB sound reduction, allowing urban dwellers maximum natural daylight without urban acoustic disturbance.
Based in Foshan, China—the world’s foremost manufacturing hub for architectural aluminium profiles—Veltor Window & Door Co., Ltd. operates a vertically integrated export facility designed explicitly for international commercial and residential orders. We bridge China’s raw material cost advantages with strict European quality control execution.
Equipped with double-head automatic mitre saws and 5-axis CNC machining centers, guaranteeing frame angle tolerance within ±0.5mm for flawless job-site installation.
Every order is supported by detailed AutoCad & 3D BIM structural shop drawings, validating wind load calculations, drainage pathways, and anchor points prior to production.
Windows are packed in reinforced, fully enclosed fumigated plywood crates with corner protection. Direct shipping options via Port of Koper (Slovenia) or Hamburg for fast Austrian customs entry.
ÖNORM B 5320 mandates a three-level sealing principle: inner vapor-tight sealing, middle thermal/acoustic insulation layer, and outer weather-proof yet vapor-permeable seal. Our frames are engineered with dedicated perimeter fixing channels and pre-applied EPDM gasket tracks compatible with RAL sealing tapes and expanding foams used by Austrian installers.
Our standard production lead time is 25 to 35 days following CAD shop drawing approval and deposit receipt. Shipping from Foshan to the Port of Koper (Slovenia)—the main logistics gateway for Southern Austria—takes approximately 22 to 28 days at sea, followed by 3-5 days of rail/truck delivery to Vienna, Graz, or Linz.
Yes. We utilize premium AkzoNobel or PPG architectural powder coatings certified under Qualicoat standards. We guarantee color uniformity (ΔE < 0.5) across large multi-container orders, ensuring seamless visual matching across residential building phases.
We supply comprehensive CE Declaration of Performance (DoP) documents along with thermal modeling calculation reports detailing $U_f$ (frame), $U_g$ (glass), and overall $U_w$ metrics under EN ISO 10077-1 standards. These documents enable your project engineering team to verify eligibility for local energy grants.
We provide a 10-year warranty on extrusion profiles and powder coating finish, and a 5-year warranty on insulated glass units and hardware mechanics. Included with every export container is a 2% spare parts package (EPDM gaskets, corner cleats, alignment keys, hardware sets) to ensure immediate site backup.
