彩石金属瓦(简称彩瓦)是一种国际流行的、填补国内空白的新型高科技屋面建筑材料。它是由金属与高分子和非金属材料复合而成的，具有全新的结构。从剖面看由上至下依次为丙烯酸面漆、彩色陶化天然石粒、丙烯酸底层、树脂涂层、Al-Zn镀铝锌涂层、钢基层、Al-Zn 镀铝锌涂层、树脂涂层。
由于以上的材料和结构特性，决定了它具有高强度、高耐腐、高弹性模量、重量轻、节能、环保等优异性能。兼具了陶土瓦、水泥瓦等传统屋面材料和彩钢瓦、玻纤沥青瓦等新型屋面材料的所有优点，外表漂亮、厚重，质地轻薄、坚韧，既可提高建筑屋面的装饰性，又可以降低工程荷载和材料消耗。
这种瓦是欧美发达国家上世纪九十年代前后发明并开始使用的，由于其美观、轻巧、耐用、环保，近年来已经成为屋面材料中的主流产品和首选材料，近几年国内的许多房地产项目也开始使用。
Colorful stone coated steel roof tile( colorful tile), is a kind of international fashion,fill the domestic blank new high-tech roofing construction materials,It is made of metal and polymer and nonmetallic material compound,with new structure. From top to bottom section for acrylic paint, color TaoHua natural stone, acrylic resin coating, Al - Zn aluminium zinc coating, the steel basic, Al - Zn aluminium zinc coating, resin coating.
Due to the above materials and structure characteristics, it has high strength, high corrosion resistance, high elastic modulus, light weight, energy-saving, environmental protection, etc. Both have the clay, cement traditional roofing tiles and caigang tiles, fiberglass asphalt roofing tile all the advantages, beautiful appearance,massiness, texture,frivolous, can rise already building roof adornment quality,and can reduce the engineering material consumption and load.
This is euramerican developed countries in the early 1990s until the invention and began to use, because of its beautiful, light, durable, environmental protection, has e the mainstream products and the first using roofing material, many domestic real estate project also begin to using it in recent years.
