What material is the colored stone metal tile made of

Colored stone metal tiles are composed of aluminum zinc coated steel plate as the substrate, colored sand particles, primer, and acrylic resin. The aluminum zinc coated steel plate substrate is made by electroplating a solution composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, and its processability and coating properties are basically the same as galvanized steel plate. Colored sand particles are the decorative layer and base protective layer of metal tiles. They are made from particles of a certain size through high-tech coloring processes and high-temperature baking. It has more than ten colors, can withstand ultraviolet radiation, and can reduce the noise caused by rainwater on metal tiles, making colored steel plate tiles rich and solemn in color, and more decorative. This is something that general colored pressed steel plate tiles do not have and cannot compare to. Primer, as a special material for tiles, is a material that provides good bonding between aluminum zinc coated steel plates and colored sand particles, and plays a significant role. Acrylic resin, as a surface protective layer, prevents fine rainwater leakage and can extend the lifespan of sand color.
