Industrial Excellence in Architectural Fenestration
Direct from Foshan—China's Premier Hub for Engineered Aluminium Extrusions & Custom Glazing Systems
Enterprise Authority & Technical Manufacturing Infrastructure
Operating from our state-of-the-art facility in Nanhai District, Foshan, Veltor Window & Door Co., Ltd. stands as a premier manufacturer and global exporter of high-performance architectural aluminium alloy windows and structural glass door systems. Designed specifically for commercial contractors, facade engineers, real estate developers, and international wholesale distributors, our product lines integrate advanced thermal-break engineering, structural durability, and architectural aesthetics.
Every window unit leaving our factory floor is engineered to meet strict international standards, including European CE certification (EN 14351-1), North American NFRC/NAFS benchmarks, and Australian AS2047 load-bearing criteria. By utilizing high-density 6063-T5 and T6 structural aluminium alloys paired with PA66-GF25 glass-fiber reinforced polyamide thermal barrier strips, our systems eliminate thermal bridging, deliver exceptional acoustic isolation (STC ratings up to 45 dB), and withstand extreme wind pressures in high-rise and coastal installations.

Future Procurement Trends in Aluminium Fenestration
Strategic insights for global project buyers, developers, and wholesale importers
1. Ultra-Low U-Value & Passive House Demands
Global energy codes (such as Europe's EPBD and North American Title 24) are mandating overall window U-factors below 1.2 W/m²K. Future procurement will shift heavily toward multi-cavity PA66-GF25 thermal breaks filled with expanded polyolefin (PE) insulation foam and triple Low-E argon-filled units.
2. Minimalist Sightlines & Large-Format Glass
Architectural design increasingly favors ultra-narrow frame profiles (16mm to 25mm visible interlocks) with heavy load-bearing structural capacities. Hardware systems must support individual glass panels exceeding 400 kg via concealed stainless steel track assemblies and motorized assist systems.
3. Automated Smart Building Integration
Commercial and luxury residential developments are integrating motorized lift-and-slide doors and automated awning actuators directly into centralized Building Management Systems (BMS), utilizing concealed sensors, electrochromic dynamic glass, and biometric access controls.
4. Circular Low-Carbon Aluminium Sourcing
Environmental Product Declarations (EPD) and low-embodied-carbon aluminium extrusions (processed using renewable hydro energy) are becoming essential prerequisite criteria for municipal tenders and LEED Gold / BREEAM certified developments.
5. Modular Pre-Assembled Crate Crating
To reduce escalating job-site labor costs in Europe, Australia, and North America, buyers are requesting factory-installed glass, pre-adjusted multipoint hardware, and opening-number-coded modular packaging for direct crane installation.
6. Enhanced Anti-Intrusion & Impact Standards
Extreme climate events and safety concerns are pushing high-specification requirements for laminated structural interlayers (SGP SentryGlas) and PAS 24 / RC3 level anti-burglary hardware configurations across export markets.
Evolution of Architectural Aluminium Extrusions & Thermal Performance
The global architectural fenestration sector has undergone a fundamental technological transformation over the past decade. Traditional non-thermal aluminium frames—once criticized for high thermal conductivity—have been rendered obsolete in modern construction due to advanced thermal break technology. By physically separating the interior and exterior aluminum profile profiles using precision-extruded Polyamide PA66-GF25 strips, thermal bridging is effectively broken, drastically lowering U-values while retaining structural rigidity.
In addition to energy conservation, structural surface finishing has advanced significantly. High-durability Fluorocarbon PVDF liquid spraying and AkzoNobel electrostatically applied powder coatings provide superior resistance to salt spray corrosion, ultraviolet degradation, and chemical oxidation, making CE-certified aluminium alloy windows exceptionally suited for severe marine environments and high-humidity tropical zones.
Soundproofing & Acoustic Insulation Science
Urban density demands elevated sound insulation. Modern double and triple glazed aluminum window systems achieve Acoustic Transmission Class (STC) ratings above 40 dB by utilizing asymmetric glass thickness combinations (e.g., 6mm outer glass + 12mm Argon space + 8mm inner laminated glass). This acoustic barrier decouples sound wave frequencies, attenuating low-frequency traffic noise and environmental vibration.
Factory Operations & Pre-Shipment Quality Control
Systematic, verifiable manufacturing excellence from raw billet to reinforced export container loading
1. Precision CNC Machining & Milling
Extruded profiles undergo double-head 45-degree angle cutting and 4-axis CNC routing for hardware mortises, drainage channels, and corner crimping slots with tolerances within ±0.5mm.
2. Corner Crimping & Chemical Sealing
Corner joints are combined using heavy hydraulic crimping machines, internal cast aluminum corner keys, and dual-component polyurethane corner seam adhesive to guarantee zero water leakage.
3. Heavy-Duty Export Crating Logistics
Finished window sashes and frames are wrapped in anti-scratch protective film, corner-shielded, and packaged inside fully enclosed steel-strapped wooden crates to prevent transit damage during sea transport.
Frequently Asked Questions for Global Procurement
Direct technical guidance for commercial buyers, architects, and trade importers
How does CE certification (EN 14351-1) protect global buyers?
CE marking confirms that our aluminium alloy windows conform to European Union health, safety, and environmental protection standards. It verifies third-party laboratory testing for air permeability, water tightness, structural wind resistance, and thermal transmittance values.
What is the minimum order quantity (MOQ) for custom project orders?
Because every fenestration unit is custom manufactured to exact architectural CAD drawings, we support project-based MOQs starting from single villa custom orders up to full 20ft/40ft container consolidations for commercial real estate developments.
Can your window systems meet North American NFRC and Australian AS2047 standards?
Yes. Our engineering team prepares shop drawings and profile selections specifically engineered to meet target regional standards, including AS2047 structural deflection limits in Australia and NFRC energy performance criteria in North America.
What hardware brand options are available for multipoint locking systems?
We offer premium global hardware integration, including German-engineered Siegenia, Hoppe, and G-U hardware sets, Italian Savio components, as well as our heavy-duty proprietary Veltor factory hardware systems backed by a 10-year warranty.
How do thermal-break aluminium windows compare to standard non-thermal windows?
Thermal-break windows feature a non-conductive polyamide strip (PA66-GF25) joining the interior and exterior aluminum profiles. This reduces thermal conduction by over 60%, eliminating interior condensation and significantly lowering HVAC energy consumption.
What is the typical factory production lead time for export orders?
Standard manufacturing lead time is 25 to 35 calendar days following written approval of CAD shop drawings and deposit confirmation. Specialized powder coating colors or custom glass laminates may require an additional 5-7 days.
How are large sliding and folding glass doors packaged for container shipping?
Door frames are knocked down (KD packaging) or shipped fully assembled depending on dimensions. Glass sashes are fitted with protective edge guards, vacuum-wrapped, and loaded into fumigated, reinforced plywood crates designed for forklift unloading.
Do you provide CAD shop drawings and technical engineering support before production?
Absolutly. Our in-house technical engineering department generates complete 2D elevation shop drawings, cross-sectional connection details, and structural glass calculations for buyer sign-off prior to profile cutting.
