Explore our premium grade extruded aluminium systems, precision engineered for superior structural integrity, thermal efficiency, and high-end aesthetic applications globally.
Understanding the shift toward ultra-low energy buildings, smart architectural facades, and advanced alloy metallurgy in modern fenestration.
The global market for aluminium window extrusions has entered a transformative era driven by stringent energy efficiency regulations, urban density growth, and architectural demands for expansive glass facades. As modern building codes mandate lower overall thermal transmittance ($U_w$ values), traditional uninsulated window frames are rapidly being phased out in favor of multi-cavity, thermally broken aluminium profile systems.
Aluminium extrusions serve as the structural backbone for contemporary architectural fenestration, structural curtain walls, sliding door assemblies, and acoustic window frames. The material's exceptional strength-to-weight ratio allows architects to design slim frame profiles that maximize natural light transmission without compromising structural stability against extreme wind pressure or seismic loading.
Utilizing high-tensile 6000-series alloys, extruded profiles offer structural yield strength capable of supporting oversized triple-pane insulated glass units (IGUs) in high-rise applications.
Aluminium is infinitely recyclable, retaining 100% of its mechanical properties while consuming 95% less energy during remelting compared to primary aluminum production.
Advanced CAD/CAM matrix dies ensure dimensional tolerances compliant with EN 755-9 and EN 12020-2 standards, facilitating effortless assembly and tight acoustic sealing.
Precision selection of chemical compositions, heat treatments, and temper designations tailored for window systems and heavy-duty structural profiles.
Selecting the optimal alloy composition is critical to achieving the required balance of extrudability, surface finish, structural integrity, and corrosion resistance. Qianyu Aluminum predominantly utilizes magnesium-silicon 6000-series alloys, subject to computer-controlled artificial aging (temper T5 and T6) to achieve optimal mechanical properties.

Our state-of-the-art hydraulic extrusion presses (ranging from 800 to 3,600 metric tons) process homogeneous aluminum billets pre-heated to precise extrusion temperatures (450Ā°Cā480Ā°C). Quenching is dynamically calibrated using intense air or water spray to freeze the solid solution phase, followed by precipitation hardening at elevated temperatures to guarantee consistent hardness (up to 12-15 Webster Hardness).
By engineering multi-cavity hollow dies with optimized bridge and chamber designs, Qianyu Aluminum manufactures intricate window profiles featuring integrated screw flutes, weather-strip retention tracks, and drainage channels with wall thickness tolerances down to $\pm 0.15\text{ mm}$.
Engineered thermal barrier strips and multi-chamber insulation profiles designed to prevent heat transfer and eliminate interior condensation.
Because native aluminum exhibits high thermal conductivity ($\lambda \approx 200\text{ W/m}\cdot\text{K}$), modern energy-efficient window systems require a structural thermal break. This is achieved by joining inner and outer extruded aluminum profiles using low-conductivity polyamide insulating strips reinforced with 25% glass fiber (PA66-GF25), which reduces heat transmission dramatically ($\lambda \approx 0.3\text{ W/m}\cdot\text{K}$).
Matches the coefficient of thermal expansion of aluminum ($2.3 \times 10^{-5}/\text{K}$), preventing shear stress failure under extreme climatic freeze-thaw cycles.
Internal chambers are populated with hydrophobic polyolefin or expanded polyurethane foams, blocking thermal radiation and convective air currents within the frame.
Combined with low-E triple glazing, our high-end thermally broken profiles easily meet Passivhaus energy efficiency certifications globally.
