Hot-dip galvanizing, abbreviated as hot-dip galvanizing, is a process in which carbon steel substrates are pre-treated and then immersed in molten zinc to obtain a protective coating. Galvanized steel sheets have been widely used in home appliances, decoration, advertising and civilian industries due to their excellent anti-corrosion performance. Especially in the home appliance industry (such as outdoor units of air conditioners, outer panels of refrigerators, panels of washing machines, computer cases, microwave ovens, etc.), there is a large demand for color-coated base plates. Hot-dip aluminized zinc silicon steel sheet, also known as Galvalume (abbreviated as GL steel sheet), is a type of steel sheet with an alloy of aluminum (Al55%), zinc (Zn43.5%), and silicon (Si1.5%) hot-dip coated on its surface. It is a steel-based composite material with excellent corrosion resistance. Hot-dip aluminized zinc alloy steel sheets not only possess the excellent atmospheric corrosion resistance and heat and oxidation resistance of aluminized steel sheets, but also have the superior electrochemical protection of galvanized steel sheets. Our company can provide hot-dip aluminized zinc plating production lines with two process technologies: the "American Steel United Process" and the independently developed "Ruisen Process".
