Colored stone metal tiles are a latest type of advanced roofing material produced using high-tech technology. They are made of aluminum zinc coated steel plates with excellent anti-corrosion properties as the substrate, water-based acrylic ester as the adhesive, sintered colored sand as the surface layer, and highly weather resistant acrylic resin as the outermost layer (equivalent to paint). Due to its beauty, lightweight, durability, and environmental friendliness, it has become the mainstream product of international roofing materials in recent years and is used in high-class buildings in China.
