Roof anti-corrosion plays a vital role in buildings. Roofs are exposed to the external environment for a long time, and are affected by factors such as wind, rain, sunlight, and temperature changes, which makes them prone to corrosion, especially in places with harsh environments such as chemical plants and coastal areas. Anti-corrosion treatment can effectively extend the service life of the roof, prevent leakage, structural damage and other problems, and ensure the overall safety and durability of the building. In addition, roof anti-corrosion can also reduce maintenance costs and improve the energy-saving effect of buildings, which is of great significance to the beauty and functionality of buildings.
