What Are The Advantages Of Galvanized Steel Sheets?

Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on the surface. It is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, and electromechanical industries. So what are the advantages of galvanized steel sheet?
1. Processing performance: The processing performance of galvanized steel sheet is similar to that of hot-dip galvanizing, which can fully meet the processing requirements of rolling, stamping, bending and other forms.
2. Corrosion resistance: The test is carried out under the premise of hot-dip galvanized steel sheets and galvanized steel sheets with the same thickness, coating, and surface treatment. Galvalume has better corrosion resistance than hot-dip galvanizing, and its service life is 2-6 times that of ordinary galvanized steel.
3. Light reflection performance: the ability of galvanized steel to reflect heat and light is twice that of galvanized steel, and the reflectivity is greater than 0.70, which is better than 0.65 stipulated by EPA Energy Star (Energy Star of the US Environmental Protection Agency).
4. Heat resistance: Ordinary hot-dip galvanized products are usually used at a temperature not exceeding 230 degrees, and the color will change at 250 degrees, while the galvanized sheet can be used for a long time without discoloration in an environment of 315 degrees. Under the environment of 300 degrees for 120 hours, the color change of Baosteel's heat-resistant passivation-treated galvanized steel plate is much lower than that of aluminum plate and aluminum plated plate.
5. Mechanical properties: The mechanical properties of galvanized steel sheets are mainly manifested in yield strength, tensile strength and elongation. Ordinary DC51D grade 150 g/square galvanized steel sheet, the general yield strength is between 140-300mpa, the tensile strength is between 200-330, and the elongation is between 13-25. The yield strength of DC51D+AZ galvanized 150 g/square galvanized steel plate is between 230-400mpa, the tensile strength is between 230-550, and the elongation rail is between 15-45.
