What are the different types of surface treatment for aluminum sheets?

There are several types of surface treatment for aluminum sheets, each serving different purposes. These include: Anodizing, which creates a protective oxide layer and enhances corrosion resistance; Chemical Conversion Coating, such as chromate conversion, to improve paint adhesion and corrosion resistance; Electrolytic Polishing, which provides a smooth, shiny surface; Powder Coating, an electrostatic process that applies a durable coating; Paint Coating, offering a wide range of colors and finishes; and Mechanical Polishing, which smooths the surface and improves reflectivity. Each treatment has its specific applications and benefits, depending on the desired outcome for the aluminum sheet.
