The appearance of double-sided anti-corrosion and heat-insulating tiles solves all the problems of color steel tiles. The anti-corrosion and heat-insulating panels use a new concept and technology, take steel plate or aluminum plate as the substrate, and compound anti-corrosion functional films on both sides, which are resistant to high temperature and high humidity. It is resistant to acid and alkali corrosion, resistant to various chemical media, and does not rust or leak water in various strong corrosive environments, achieving both thermal insulation and anti-corrosion at the same time. It is a new generation of anti-corrosion factory roof tiles, which are applied to factory roofs and walls in various corrosive environments. Compared with the color-coated color-coated steel tile products commonly used for factory and building surfaces, it is a new type of material for energy saving and emission reduction, and is an environmentally friendly material strongly encouraged and advocated by the state.
