This series of aluminum profiles is specifically designed for building window and door systems and glass curtain wall systems. Manufactured from high-quality aluminum alloy base material, the profiles undergo precision extrusion and multiple surface treatment processes, offering a combination of light weight, high strength, excellent weather resistance, corrosion resistance, and ease of fabrication. They are widely used in the external envelope structures of residential buildings, office buildings, commercial complexes, and public buildings. The profiles feature high strength and a stable structure, with well-designed cavity configurations and reinforcement ribs that deliver outstanding wind load resistance, reaching Level 5 or above per national standards. This makes them especially suitable for high-rise buildings and coastal areas. The surface is treated either by anodizing or powder coating, providing resistance to UV radiation, salt spray, and acid rain, ensuring no fading or chalking even after prolonged use.
