Color-coated coils are lightweight, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray-white, sea-blue, and brick-red. They are mainly used in advertising, construction, household appliances, electrical appliances, and furniture. industry and transportation. Corrosion resistance and decorative properties, as well as high strength and easy processing properties of steel plates, are deep-processed products in the iron and steel industry.
High-efficiency and energy-saving steel. In recent years, high-quality and multi-purpose color coated steel plate 4102 has developed rapidly, and high corrosion resistance color steel plate 1653, high formability color steel plate, fingerprint-resistant color plate and antibacterial color steel plate are very promising. Colored steel coils with organic coatings of various colors are named after them, and are referred to as color-coated coils.
In addition to the protection of zinc layer, the color-coated steel strip using hot-dip galvanized steel strip as the base material, the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and its service life is longer than that of the galvanized strip. The product obtained by coating the organic coating on the hot plate with the zinc substrate is the hot-dip galvanized color-coated plate.
Since the zinc layer of the electro-galvanized sheet is thin, usually the zinc content is 20/20g/m2, so this product is not suitable for making walls, roofs, etc. outdoors. But because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc. about 1.5 times.
