Aluminum Alloy System Windows

For modern architectural projects, aluminum alloy system windows represent the pinnacle of engineering and design. Our expansive selection addresses every performance need through rigorously tested solutions such as Integrated System Windows, which merge frame, sash, hardware, and glass into a perfectly coordinated assembly for seamless installation and lasting durability. For projects demanding elevated aesthetics and strength, we offer Premium System Windows crafted from high-grade extruded aluminum with enhanced thermal break technology. Builders seeking future-ready automation will appreciate our Smart System Windows, which integrate sensor-driven controls and remote operation without compromising the clean, minimalist look of aluminum framing. Equally vital is energy performance, which is why our Energy-saving System Windows employ multi-chamber insulating profiles and low-E coated glazing to dramatically reduce thermal transfer in both hot and cold climates. Each product line is developed in compliance with strict international fabrication standards, ensuring that structural integrity, weather resistance, and acoustic comfort are never compromised.
At the core of every project lies an Aluminum Alloy System Windows construction designed to outperform traditional fenestration in every measurable category. The raw material itself sets these windows apart: we use primary 6063-T5 aluminum alloy with a tensile strength exceeding 160 MPa, which allows slim sightlines while handling large spans and heavy glass loads. The profiles undergo a multi-stage surface preparation—chrome-free pretreatment followed by a high-performance polyester powder coating compliant with Qualicoat Class 2 or 3 specifications—to deliver outstanding corrosion resistance and color stability for decades. Thermally broken frames incorporate 24 mm to 42 mm wide high-density polyamide strips, reinforced with glass fiber, that interrupt conductive heat flow and achieve U-values as low as 0.8 W/m²·K when combined with triple-pane glazing. Air infiltration is controlled to levels below 0.1 cfm/ft² under 75 Pa pressure, while water penetration resistance consistently meets 900 Pa or higher without leakage, attributable to the internal EPDM gasket network and integrated drainage chambers. Sound insulation reaches Rw values up to 47 dB, making these windows suitable for urban high-rises and sites near traffic corridors. The detailed parameters below illustrate the technical depth behind every window we produce.

• Frame Material: 6063-T5 aluminum alloy, extruded to EN 755-2 and EN 12020 tolerances
• Thermal Break: 24 mm to 42 mm polyamide strips (PA66 GF25), bonded using dual-component polyurethane for structural shear strength
• Surface Finish: Qualicoat Class 2/3 powder coating (60–90 µm), marine-grade anodizing (AA15–AA25), or wood-effect sublimation
• Glazing Options: Double or triple insulated glass units, argon-filled, with warm-edge spacers; low-E coatings on surfaces #2 and/or #4; thickness from 24 mm to 52 mm
• Gasket System: Co-extruded EPDM closed-cell weather seals with corner vulcanization for continuous airtightness
• Hardware Integration: Concealed multi-point locking with adjustable rollers, stainless steel corner drives, and corrosion-proof handles tested to 25,000 cycles
• Design Pressure: ± 3,000 Pa (serviceability), ± 4,500 Pa (ultimate), depending on mullion reinforcement
• Acoustic Performance: Rw 35–47 dB based on glass makeup and frame insulation
