The use of color coated boards is generally divided into three categories: building, transportation, and household appliances. The building color coated panels occupy a larger part. The household appliances industry is the second, and the proportion of transportation and transportation is relatively minimal. The building color coating plate is usually made of hot-dip galvanized steel sheet and hot-dip aluminum zinc steel sheet. It is mainly processed into corrugated board or polyurethane sandwich panel, which is mainly applied to roofs, walls and doors of industrial and commercial buildings such as factory buildings, airports, storehouses, refrigerated warehouses, etc. The home appliance color plate is usually based on electric galvanizing and cold plate. It is commonly used in the refrigerator shell or the large air conditioning shell of the enterprise, the freezer, the bread machine, the furniture and so on. Most of the substrates used for transportation are galvanized and cold plates, which are mainly used for oil pan, automotive interior parts and so on.
Generally speaking, building color plates than appliances with higher strength steel substrate, corrosion resistance, this is because the construction of color coated sheet is usually subject to a part of the structure, the working environment in the outdoor environment, service life is relatively longer, so it is necessary to have high strength and corrosion resistance.
