The lifespan of galvanized sheets in different environments is about 20 to 70 years. The transparent and beautiful appearance of galvanized sheet is one of the main advantages of this type of sheet compared to steel sheets. The cost of galvanizing operations, maintenance and repairs of galvanized sheets is lower. With this method, all the surfaces of the sheet, including depressions, corners and edges of the sheet are covered and corrosion is prevented. The possibility of easy shaping and welding is another advantage of galvanized sheet. Chromated galvanized products have the ability to accept color, which makes them more resistant to corrosion. Hot galvanized coating is harder and 5 times more wear resistant than other methods (such as color coating).
