Precision-Engineered Window & Door Platforms
Explore our structural window frame systems, manufactured to rigorous international standards (NFRC, AS2047, CE) using 6063-T5 aluminum alloys, Technoform thermal breaks, and German multi-point hardware.
China's Premier Fenestration Engineering Factory
As a tier-one OEM/ODM window frame manufacturer in China, we bridge high-capacity industrial production with bespoke architectural engineering. Every frame system is custom-extruded, thermally broken, and fully assembled to match exact project specifications.
Certified Thermal Performance
Integrated Technoform PA66 polyamide thermal breaks eliminate heat bridges, delivering frame U-factors down to 0.28 BTU/h·ft²·°F (1.6 W/m²K) in accordance with NFRC testing criteria.
Rapid Delivery & Stock Reserves
Our factory maintains over 300 metric tons of pre-certified 6063-T5 aluminum extrusions in stock, accelerating lead times by 35% compared to standard mill-run schedules.
German Multi-Point Hardware
Standardized with authentic GU, Siegenia, Hoppe, and Kinlong hardware systems tested to withstand 50,000 continuous operation cycles without mechanical failure.
Window Frame Material Science & Structural Matrix
Selecting the correct window frame alloy grade, thermal break geometry, and glass build-up is critical for structural integrity, energy compliance, and acoustic insulation. Review our standard platform technical parameters below:
| System Series | Frame Profile Depth | Alloy & Wall Thickness | Thermal Break Tech | Glazing Specification | Acoustic Insulation | Design Pressure (DP) |
|---|---|---|---|---|---|---|
| 67T Casement Platform | 67 mm | 6063-T5 / 1.6 mm | 14.8mm PA66 Polyamide | 5mm Low-E + 12A + 5mm Tempered | STC 34 dB | DP 45 (2150 Pa) |
| 78T Ultra-Energy Platform | 78.3 mm | 6063-T5 / 1.8 mm | 24mm Multi-Cavity Strip | 5mm Low-E + 16A + 5mm Triple Option | STC 38 dB | DP 60 (2870 Pa) |
| 86 Series Heavy-Duty | 86 mm | 6063-T5 / 2.0 mm | High-Density Insulated Foam | 6mm Low-E + 14A + 6mm Laminated | STC 42 dB | DP 75 (3590 Pa) |
| EU-Standard UPVC Vinyl | 70 mm Chamber | High-Impact PVC / 2.5mm | Multi-Chamber Air Pockets | 4mm + 16A + 4mm Argon Filled | STC 32 dB | DP 40 (1910 Pa) |
| 150T Architectural Wall | 150 mm Structural | 6063-T6 / 3.0 mm | Double-Bridged Thermal Strip | 8mm Low-E + 18A + 8mm Structural IGU | STC 45 dB | DP 90 (4300 Pa) |
Thermally Broken Aluminum vs. Traditional UPVC & Wood
In modern commercial and high-end residential architecture, the debate between structural materials centers on structural span limits, thermal movement, and long-term environmental degradation.
While UPVC (vinyl) offers initial cost advantages, standard vinyl frames suffer from a high coefficient of linear thermal expansion, leading to frame warping and seal degradation in extreme climates. Solid timber, while naturally insulating, requires extensive cyclical maintenance and succumbs to moisture expansion.
Thermally Broken 6063-T5 Aluminum solves these engineering trade-offs. By mechanically joining inner and outer extruded aluminum profiles with a low-conductive polyamide strip (PA66 GF25), thermal conduction is effectively severed while retaining aluminum's immense tensile strength.
- Zero Structural Sag: Supports floor-to-ceiling glass units exceeding 3.5 meters in height.
- 25-Micron Fluorocarbon Coating: Superior resistance to UV fading, coastal salt spray, and acid rain.
- Acoustic Damping: Multi-chambered hollow profiles combined with EPDM triple-sealing gaskets reduce ambient city noise by up to 45 decibels.
Future Sourcing & Manufacturing Trends in China
For global developers, general contractors, and fenestration importers, understanding the operational shift within China's window manufacturing hubs is essential for securing supply chain resilience.
1. Decarbonization & Low-Carbon Aluminum
Under international CBAM (Carbon Border Adjustment Mechanism) regulations, leading Chinese factories are transitioning to hydro-powered primary aluminum smelting. Specifying low-embodied-carbon aluminum frames ensures compliance with green building standards like LEED v4 and BREEAM.
2. Ultra-Narrow Sightlines & Hidden Sashes
Architectural demand is moving rapidly toward concealed sash profiles where frame margins are recessed directly into the outer building envelope. Minimalist frames with 18mm to 25mm visible sightlines now dominate luxury residential procurement schedules.
3. Digital Twin & BIM Submittals
Tier-1 Chinese manufacturers now deliver direct Revit BIM models and CAD shop drawings prior to extrusion cutting. This eliminates field measuring errors and ensures seamless integration into pre-cast concrete or steel structure openings.
Factory Quality Control & Ocean Logistics
Cross-border fenestration procurement requires absolute confidence in factory inspection and export packing protection to prevent damage during sea freight transportation.
Strict 4-Stage Factory Inspection
Every batch of window frames produced in our facility undergoes rigorous verification before container loading:
- Material Composition Test: Spectrometer analysis verifying 6063-T5 aluminum purity and wall thickness tolerance.
- Water Resistance Chamber: Full frame pressure-spray testing at 600 Pa to verify EPDM gasket seals and weep hole drainage paths.
- Corner Joint Shear Testing: Hydraulic corner crimp testing ensuring joints exceed structural wind load thresholds.
- Heavy-Duty Export Crating: Standardized A-Frame steel racks with foam wrap, corner guards, and vacuum-sealed plastic wrap to prevent transit scratching and moisture oxidization.
Window Frame Sourcing & Technical FAQ
Everything you need to know about importing high-performance window frames directly from our factory in China.
Our window and door platforms are independently tested and certified by Intertek and third-party laboratories. We provide full compliance documentation for NFRC (U-Factor, SHGC, VT, AIR), NAFS structural performance ratings, AS2047 (Australian Standards), and CE mark certifications required for European building codes.
We do not enforce standard stock sizes. Every project is engineered to order. Simply submit your window schedule or architectural drawings. Our engineering team returns detailed CAD shop drawings—including profile cross-sections, glass build-ups, anchor locations, and drainage details—for your sign-off before fabrication begins.
We partner with premier hardware suppliers globally. Standard options include German GU (Gretsch-Unitas), Siegenia, Hoppe, and CMECH, as well as top-tier Asian brands such as Kinlong and KWI. We also accommodate client-specified lock cylinders or panic bar hardware for commercial projects.
Standard fabrication time is 25 to 35 calendar days following final CAD shop drawing approval and deposit receipt. For custom anodized or RAL powder-coated finishes, lead times average 30 to 40 days depending on total order volume.
We utilize multi-cavity Technoform polyamide thermal breaks paired with high-density polyurethane insulation foam inside the profile chambers. Combined with triple-glazed units featuring double Low-E coatings, warm-edge spacers, and 90% argon gas fill, our systems maintain indoor temperature stability in climates ranging from -30°C to +45°C.
Our baseline factory MOQ is 50 square meters, making us highly accessible for luxury custom residential villas as well as large-scale commercial developments. Bulk container orders benefit from tiered FOB/CIF pricing structures.
