Are there any special coatings or treatments required for outdoor use of aluminum profiles?

For outdoor use of aluminum profiles, special coatings or treatments are often required to protect against weathering, corrosion, and UV damage. Anodizing is a common process that increases the durability and resistance of aluminum. Powder coating is another method used for additional protection and to provide a wide range of colors. Some profiles may also be treated with a clear coat to maintain the natural look of aluminum while still offering protection. It's important to select the appropriate treatment based on the specific environmental conditions and aesthetic requirements of the application.
