Galvanized steel sheet is a welded steel sheet with hot-dip or electroplated zinc layer on the surface. It is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc. So what are the advantages of galvanized steel sheet? What are the advantages of galvanized steel sheet? 1. Processing performance: Aluminum-zinc steel sheet is similar to hot-dip galvanizing in processing performance, and can fully meet the requirements of rolling, stamping, bending and other forms of processing. 2. Corrosion resistance: The test is conducted on hot-dip galvanized steel sheet and aluminum-zinc steel sheet with the same thickness, coating, and surface treatment method. Aluminum-zinc has better corrosion resistance than hot-dip galvanizing, and its service life is 2-6 times that of ordinary galvanized steel sheet. 3. Light reflection performance: The ability of aluminum-zinc to reflect heat and light is twice that of galvanized steel sheet, and the reflectivity is greater than 0.70, which is better than the 0.65 specified by EPA Energy Star.4. Heat resistance: Ordinary hot-dip galvanized products usually do not exceed 230 degrees, and will change color at 250 degrees, while galvanized steel sheets can be used for a long time at 315 degrees without changing color. At 300 degrees for 120 hours, the color change of Baosteel's heat-resistant passivated galvanized steel sheets is much lower than that of aluminum sheets and aluminum-plated sheets.
