As a wall decoration material, the coated steel plate has excellent performance. It uses high-strength steel plate as the base material, and is covered with a layer of corrosion-resistant and anti-aging polymer film on the surface. This film can not only effectively resist the erosion of ultraviolet rays, chemicals and moisture, but also has the characteristics of wear resistance and easy cleaning. The coated steel plate has a variety of colors, long-lasting gloss, and beautiful decorative effects. Its good fire resistance and sound insulation properties make it widely used in the exterior and interior wall decoration of industrial, commercial and civil buildings.
