Common types of metal finishes include polishing, plating, and anodizing. Each method alters the surface characteristics, providing different textures, colors, and protective qualities. Metal finishes are essential in various industries, including automotive, aerospace, and construction. They not only improve the aesthetic appeal of products but also extend their lifespan by protecting against environmental factors. Proper finishing techniques can significantly impact the performance and maintenance of metal items.
