Pre-coated steel, also known as prepainted steel or color-coated steel, features a protective layer of paint or other coating on the finished product. It offers many advantages, such as improved corrosion resistance, longer durability, and an attractive appearance – making it ideal for building and construction, automotive industry products, appliances, and furniture.
