Color coated steel coil are widely used in the construction market, with good corrosion resistance, easy-processing and light-weight. Color-coated steel coil are used in many fields, including construction, home appliances, and transportation. In the field of construction, color-coated steel sheets are widely used in the construction of roofs and walls of industrial and commercial buildings such as steel structure workshops, warehouses, and freezers because of their light weight, beautiful appearance and good anti-corrosion performance. In the field of household appliances, color-coated sheets are used to produce the surface of household appliances such as refrigerators and microwave ovens. In terms of transportation, it is used for the production and processing of oil pans, automotive interior parts, etc.
The market usage of color-coated sheets are mainly divided into three parts: construction, home appliances, and transportation. Among them, the proportion of construction is high, followed by home appliances and transportation. Color-coated steel coil are generally made of hot-dip galvanized steel sheets and hot-dip galvalume steel sheets, which are mainly processed into corrugated cardboard or sandwich panels, which are used to build the roofs of industrial and commercial buildings such as steel structure workshops, airports, warehouses, freezers, etc. Color coated steel coil for household appliances generally use galvanized plates and cold rolled plates, which are used in the production of refrigerators, large air conditioning systems, freezers, bread machines, furniture, etc. The transportation industry generally uses galvanized sheet and cold sheet as the base material, which are mainly used for oil pan, automobile interior parts, etc.
Color-coated steel coil uses a color-coated steel plate with galvanized or galvalume steel plate as the substrate. In addition to zinc or alu-zinc protection, the organic coating on the zinc or alu-zinc layer also plays the role of covering and isolation, which can prevent the steel plate from rusting.
