The general pre-painted galvanized steel coil are hot dip galvanized and hot dip aluminum zinc. It can't be distinguished in appearance, and can only be seen through the color-coated steel coil outer packaging logo. The base plate of the color steel coil is hot-dip galvanized, the raw material of the hot-dip galvanized is cold-rolled sheet, and the cold-rolled sheet is coated with a layer of zinc on it. Now galvanizing is generally hot-dip galvanizing, and there is very little electroplating, so Color steel coils are cold-rolled sheets.
Prepainted galvanized steel coil are the mainstream in the construction field. The product has a variety of outstanding properties. Its high strength can be used as a ceiling slab structural plate for load bearing, compression and bending resistance, rich color, and a variety of different colors to meet different requirements of users. . In the form of continuous development of various industries, users of color coated rolls are also increasing, but with the continuous rise of manufacturers.
At present, there are many colors of paint on the market, and many users cannot make good choices. The production process is to roll the hard coil into a zinc pot and plate the surface with metal zinc. The production process of hot dip galvanizing can ensure the adhesion of metal zinc on the surface of the steel plate. The zinc layer can provide excellent corrosion resistance and extend the service life of the product.
PPGI steel coils are widely used in the construction of electrical appliances for the construction of household appliances, vehicles and vessels, etc. In recent years, the use of exports to ensure increased profits has become a trend for Chinese steel companies. China's overcapacity, a serious imbalance between supply and demand, peak avoidance and valley filling, steel prices have fallen sharply in the era of low profit, but steel prices in the international market have fallen less, so quotations have an advantage.
