Laminated metal plate is a composite metal plate, including galvanized or galvanized metal substrate, chemical treatment layer, polymer conversion layer, high weather resistance and anti-corrosion film layer. It is a cost-effective building roof and wall maintenance material , The material that meets the various performance combinations required by the modern construction industry, the film-coated metal plate takes full advantage of the rigidity and strength of the metal substrate material and is firmly combined with the high-weather-resistant engineering resin film. Due to the weather resistance, ultraviolet resistance, humidity and heat aging resistance, acid and alkali corrosion resistance, oxidation resistance (sodium hypochlorite and ozone), and fire resistance of the coated metal plate, the mechanical, chemical, physical and other comprehensive properties of different component materials can be fully exerted in modern buildings. widely used.
