What are the different types of coatings used to protect aluminum profiles from corrosion?

Aluminum profiles are protected from corrosion through several types of coatings. These include: Anodizing, which forms a protective oxide layer; Powder Coating, a durable and weather-resistant finish; Electrophoretic Deposition (E-coat), offering a smooth, corrosion-resistant surface; Fluoropolymer coatings, known for their exceptional chemical resistance and UV stability; and Thermal Spray Coatings, which provide a hard, wear-resistant surface. Each method serves to enhance the aluminum's resistance to environmental factors and extend its lifespan.
