    What are the maintenance methods for galvanized steel sheets

    1. Prevent scratches: The surface of the galvanized steel plate is covered with a layer of zinc. This layer of zinc can effectively prevent oxidation and corrosion on the surface of the steel plate. Therefore, if the surface of the steel plate is scratched, the zinc layer will lose its protective...
