Laminated metal tile is a kind of composite metal plate, including galvanized or galvanized metal substrate, chemical treatment layer, polymer conversion layer, weather-resistant and anti-corrosion film layer. It is a cost-effective building roof and wall maintenance material. Materials that meet the needs of a variety of performance combinations required by the modern construction industry, film-coated metal tiles are firmly combined with weather-resistant and anti-corrosion resin films on the basis of making full use of the advantages of rigidity and strength of metal substrate materials. Because the coated metal tile has weather resistance, ultraviolet resistance, humidity and heat aging resistance, acid and alkali corrosion resistance, oxidation resistance, and fire prevention, it can exert the mechanical, chemical, and physical properties of different component materials to a large extent, and has been widely used in modern building roofs. , especially factories with harsh environments such as industrial plants, ceramic factories, fertilizer factories, and farms.
