Aluminum profiles for building curtain walls

Nanshan AKLU curtain wall aluminum profile
Surface treatment is divided into the following processes:
Anodizing: This is a common surface treatment method for aluminum profiles, which improves its corrosion resistance and hardness by forming an oxide film on the surface of the aluminum profile. The thickness and color of the oxide film can be adjusted as needed.
Electrophoretic coating: This is a way to electrophoretically apply paint to the surface of the aluminum profile, which can form a uniform coating and improve its corrosion resistance and appearance. Electrophoretic coating can use different coatings to meet different needs.
Spraying: This is a way to spray paint onto the surface of the aluminum profile, which can form different colors and textures. Spraying can use different coatings, such as polyester, polyurethane and epoxy resin. Spraying processes include electrostatic powder spraying and fluorocarbon spraying.
Electrostatic powder spraying: Using the principle of electrostatics, the powder coating is evenly sprayed on the surface of the aluminum profile to form a strong, beautiful and corrosion-resistant coating.
Fluorocarbon spraying: The aluminum profile is sprayed with fluorocarbon coating to improve its resistance to ultraviolet radiation, weather resistance and corrosion resistance. Fluorocarbon spraying process usually includes multiple layers of coating such as primer, topcoat and varnish to form a tough and beautiful coating.
The alloy state of AKLU curtain wall profiles mainly includes the following states:
‌T4 state‌: T4 state is the state of natural aging after solution treatment. The aluminum profile in this state has low hardness and good deformability, which is suitable for later bending and other processing.
‌T5 state‌: T5 state is the state of incomplete artificial aging after solution treatment. The aluminum profile in this state has high hardness and is suitable for applications requiring higher hardness, such as curtain walls.
‌T6 state‌: T6 state is the state of complete artificial aging after solution treatment. The aluminum profile in this state has the highest hardness and is suitable for occasions with extremely high requirements for material hardness.
The definitions and performance characteristics of these states are as follows:
‌T4‌: Solution treatment + natural aging, low hardness and good deformability.
‌T5‌: Solution treatment + incomplete artificial aging, high hardness and moderate deformability.
‌T6‌: Solution treatment + complete artificial aging, highest hardness and lowest deformability.
