To prevent rusting on aluminum sheets during installation, ensure that the aluminum is of high quality and free from impurities. Keep the surface clean and dry at all times, avoiding contact with corrosive materials. Use appropriate protective coatings or sealants that are compatible with aluminum. Avoid scratches or dents that can expose the metal to moisture. Store aluminum sheets in a dry place before installation. During installation, handle the sheets carefully to avoid damage. Regularly inspect and maintain the aluminum sheets to catch any signs of corrosion early.
