789 Aluminum Profile for Sliding Window
The 789 series sliding windows are one of the most common types of aluminum alloy windows. Here is a cross-sectional diagram of the 789 series aluminum profiles. The surface treatment can be customized according to requirements.
Surface
Surface treatment for aluminum window profiles serves two important purposes: protection and customization. There are several straightforward methods for this. Anodizing involves creating a protective oxide layer through an electrochemical process, providing corrosion resistance. Electrophoretic coating (e-coating) ensures even coverage and enhanced durability. Powder coating uses dry powder for a tough, colorful finish. PVDF coating offers excellent weather resistance. Wood grain transfer printing replicates a wood texture for a natural look. Each of these methods caters to different needs, from safeguarding against the elements to achieving a desired aesthetic for aluminum window profiles.
Anodizing
The aluminum profiles are immersed in an acidic solution and undergo electrolytic oxidation to form an oxide film. Anodizing enhances the corrosion resistance, hardness, and surface smoothness of the aluminum profiles. It can also be used with dyeing agents to achieve different colors.
Class of oxide film: AA10; AA15; AA20
Surface type: Matte; flat
Color: Silver white; bronze; champagne
Fetures: Corrosion resistant; durable; shining and decorative
Electrophoretic Coating
The charged aluminum profiles are immersed in a coating solution in an electrolytic tank. Through electrophoresis, the coating evenly adheres to the aluminum surface. Electrophoretic coating provides good weather resistance, color stability, and a smooth and uniform coating.
Corrosion resistance of composite film: ≥9.5 level
Paint film cohesive: Zero lever
Paint film hardness: ≥3H
Surface: Matte; flat; high brightness
Color: Silver white; bronze; champagne
Features: Corrosion resistant; durable; smooth and shining
Powder Coating
Powdered coating material is sprayed onto the aluminum profiles, and then melted and cured at high temperatures. Powder coating offers durability, corrosion resistance, and a pleasing appearance. It is also environmentally friendly.
Coat thickness:40-120um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Surface type: Highly glossy; semi glossy; matte
Color: Ral color
Features: Variety of colors
PVDF Coating
PVDF coating, a type of spray coating, utilizes a PVDF resin-based paint that provides exceptional resistance to weathering, UV radiation, and chemicals, making it suitable for demanding outdoor applications.
Coat thickness:30-65um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Glossiness: 60°
Features: With metallic luster, bright color, high weather resistance
Wood Grain Transfer
This process involves transferring wood grain patterns or textures onto the aluminum profiles using a transfer method. It gives the aluminum profiles the appearance of wood while retaining the advantages of aluminum, such as weather resistance and corrosion resistance.
Surface texture: Wooden; marble
features: Wood-like visual experience
