Surface Treatment Processes for Aluminum Coil
Aluminum coil surface treatments are mainly used to improve corrosion resistance, decorative appearance, adhesion performance, and functional properties.
Polishing / Mirror
Mechanical or chemical polishing is used to make the aluminum surface smoother and brighter.
Brushed
Mechanical brushing creates uniform linear textures on the aluminum surface.
Anodizing
An electrochemical process that forms a dense oxide layer on the aluminum surface.
Coating / Painting
An organic or inorganic coating is applied to the aluminum surface, commonly PE, PVDF, or epoxy coatings.
Embossed
Patterns are pressed onto the aluminum surface using embossing rollers.
Diamond
The surface features aluminum sheets embossed with a diamond pattern using a roller. This process creates a raised texture that enhances both functionality and aesthetics.
Application Industries of Aluminum Coil
Aluminum coils are widely used in building decoration, transportation, electronics, packaging materials and other fields, playing an important role in the national economy.
