Metal roof tile anti-corrosion is essential for the overall durability and safety of a building. Since metal materials are prone to oxidation and corrosion in a humid environment, roof tiles that have not been treated with anti-corrosion treatment may cause leaks, structural damage, and reduced aesthetics. Anti-corrosion measures not only extend the service life of roof tiles, but also reduce the frequency of repairs and replacements, reduce maintenance costs, and ensure the waterproof performance and structural stability of the building, thereby improving the overall building quality and living comfort.
