Galvanized sheet refers to a steel sheet with a layer of zinc on its surface. Galvanizing is an economical and effective method of rust prevention that is often used, and about half of the world's zinc production is used in this process. Galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life, and a layer of metal zinc is coated on the surface of the steel plate, and this galvanized steel plate is called galvanized plate.
Aluminum-galvanized coil/plate refers to the steel plate coating on the basis of zinc with aluminum (passivation protection), the general composition is 55% aluminum, 43.5% zinc, 1.5% silicon, with excellent atmospheric corrosion resistance, corrosion resistance is 2-4 times that of galvanized sheet, but also has the high temperature corrosion resistance of aluminum plate, smooth surface, good appearance.
Color coated plate, also known as color steel plate or color plate in the industry. Color coated steel plate is a type of plate material obtained on a continuous unit using cold-rolled strip steel, galvanized strip steel (electroplated and hot-dip galvanized) as substrates, surface pre-treatment (degreasing, cleaning, and chemical treatment), roller coating method, one or more layers of liquid coating, and baking and cooling.
