Premium China Aluminium Profiles for Door and Window Frames

Our durable China aluminium profiles are made from high-quality 6063-T5 aluminum alloy, offering a perfect balance of lightweight design and high strength. These profiles can withstand typical structural loads in the construction industry, ensuring long-term stability of doors and windows. The surface is treated with advanced anodization, providing excellent corrosion and oxidation resistance, suitable for coastal, humid, and high-temperature environments, extending the service life of the frames. Additionally, the profiles feature precision extrusion technology and scientific cross-sectional design, ensuring accurate dimensions and easy assembly with various hardware fittings. Smooth surfaces, precise cutting, and strict quality control meet international building standards, helping customers reduce rework, save materials, and secure reliable supply for their construction projects.
