Engineered for modern architectural excellence, our aluminium curtain wall profiles deliver unmatched structural integrity, weather resistance, and energy efficiency. Precision-extruded from high-grade 6063-T5/T6 alloys, these profiles are lightweight yet exceptionally durable, designed to withstand extreme wind loads, seismic activity, and temperature fluctuations (-30°C to +80°C). Featuring thermal break technology with 24mm polyamide insulation bars, our systems achieve U-values as low as 1.8 W/m²K, complying with EN 14024 and ASTM E283/331 standards for superior thermal and acoustic performance.
Customizable in mill finish, powder-coated (RAL/Patina colors), or anodized surfaces (AA-M20-C22-A41), the profiles support unitized/modular curtain wall installations with concealed or exposed framing options. Compatible with double/triple glazing and photovoltaic integrations, they enable LEED-certified sustainable designs. All profiles undergo ISO 9001-certified CNC processing, including CNC milling (±0.1mm tolerance) and hardware pre-machining for seamless on-site assembly. Backed by 25-year anti-corrosion warranties and full AAMA 2605 certification, our solutions empower architects and contractors to create iconic, energy-smart façades for high-rises, airports, and commercial hubs worldwide.
Aluminium Profiles For Curtain Wall is the core structural material of the building curtain wall system, which is mainly used for the peripheral protective structure of high-rise buildings, commercial complexes and public facilities. Through the combination of aluminum alloy profiles and glass, metal plates and other panels, it forms both decorative and functional building exterior walls, which has the characteristics of lightweight, high strength, corrosion resistance and so on, and meets the needs of energy saving and environmental protection.
About Us
The Sunshine Seamless Welding Doors and Windows belongs to the brand under Guangdong Yuepai Doors and Windows Co., Ltd.

Specializing in high-end aluminum alloy sliding doors, swing doors, broken bridge windows, main doors and other series, with supporting products of high-end system door and window profiles.
What alloys are commonly used for aluminium curtain wall profiles?
Aluminium curtain wall profiles primarily use 6000-series alloys such as 6063-T5/T6, 6061-T6, and 6082-T6. These alloys offer excellent strength, corrosion resistance, and adaptability to complex designs. Heat-treated tempers (e.g., T5, T6) enhance mechanical properties for structural stability.
What surface treatments are available for these profiles?
Options include powder coating, anodizing, PVDF coating, and wood-grain transfer. Powder coatings provide 60–120 µm thickness for durability, while anodizing (10–20 µm) ensures corrosion resistance. Custom colors and textures are available to match architectural aesthetics.
Can these profiles be customized for specific designs?
Yes, manufacturers support full customization based on drawings (DWG/IGS formats) for shape, size, and surface finish. Complex geometries like curved or structural glazing systems are achievable. Custom mold development takes 30 days.
What certifications ensure product quality?
Profiles comply with GB 5237 (China), EN755 (Europe), and AAMA standards (e.g., CW-DG-1 for curtain walls). Certifications like ISO 9001, CE, and RoHS guarantee quality, environmental safety, and international compliance.
How energy-efficient are aluminium curtain walls?
They integrate thermal break systems to minimize heat transfer, reducing energy consumption. Insulated glazing units (IGUs) and low-E glass further enhance thermal performance, supporting green building certifications like LEED.
What is the typical lifespan of these profiles?
Outdoor durability ranges from 18–25 years for powder-coated profiles and 12–15 years for anodized ones, depending on environmental conditions. Regular cleaning and maintenance extend longevity.
How are these profiles installed?
Installation methods include:Stick System: On-site assembly of mullions and transoms.Unitized System: Pre-fabricated modules for rapid installation.Structural Glazing: Seamless glass bonding for modern aesthetics. AAMA guidelines (e.g., CWG-1) ensure proper sealing and load distribution
What are the minimum order requirements and lead times?
MOQ: 500 kg per design.Lead Time: 10–30 days for standard orders; 7–10 days additional for new molds.Samples: Free samples available with freight costs borne by the buyer
