What are the different types of aluminum sheets used for exterior applications?

Aluminum sheets used for exterior applications come in various types, each with specific properties to withstand weather and environmental conditions. These include: 1. Mill Finish Aluminum Sheets: These have a natural aluminum finish and are used for applications requiring a raw, industrial look. 2. Anodized Aluminum Sheets: These are aluminum sheets that have been treated to increase their resistance to corrosion and wear. 3. Painted Aluminum Sheets: These are coated with a layer of paint for added protection and aesthetic appeal. 4. Embossed Aluminum Sheets: These have a textured surface and are used for decorative purposes or to provide a non-slip surface. 5. Perforated Aluminum Sheets: These are aluminum sheets with holes punched through them, used for ventilation or decorative purposes. Each type is chosen based on the specific requirements of the exterior application, such as durability, aesthetics, and environmental resistance.
