“She is in the window-seat, to be sure, Jack.”

1.质轻坚固每平方米的重量约6KG,相当于传统水泥瓦的八分之一，精确的搭接与紧固使屋顶更加坚固，避免了屋顶塌陷的可能性。同时又节约了运输费用、仓储费用及施工成本。

耐久性高品质的镀铝锌基板和天然石防护层具有良好的防腐蚀性能，使彩石金属瓦、蛭石金属瓦、彩砂金属瓦的使用寿命可长达50年。

2.经济性每片彩石金属瓦、蛭石金属瓦、彩砂金属瓦的覆盖面积是传统瓦片的六倍，且质量非常轻，这使得安装、装卸、储存变得更加的省时和高效。一旦安装完成，后期的维护成本极低，几乎可忽略不计。

3.可循环性彩石金属瓦、蛭石金属瓦、彩砂金属瓦采用高品质镀铝锌钢板为基材，可循环再利用成分含量可高达90%以上，有效的降低了使用成本。

4.超强装饰性颜色与造型的多种选择与超强的立体感，与现代建筑艺术完美结合，具有极强的装饰效果。

5.易于安装质轻，易于安装的瓦片设计，使得彩石金属瓦、蛭石金属瓦、彩砂金属瓦能够在木质的龙骨及轻钢龙骨上顺利铺设。

6.科学施工科学及精确的搭接设计、专业的安装说明确保安装过程能够及时情却完成。

7.施工安全独特的设计及生产工艺，使高空施工的时间大大缩短，增加了施工的安全性。铺设过程中的切割也不会想陶瓦一样产生大量粉尘，因此极具环保性。

用金属制成的瓦，有好几种类型；通过使用这些金属瓦，我们可以代替过去使用的水泥瓦、陶土瓦。现在在市场卖的金属瓦总共有三种，一种是石面金属瓦、一种是漆面金属瓦、一种是金属本色瓦。其中的石面金属瓦也被叫做彩石金属瓦、蛭石金属瓦、彩砂金属瓦，制成之后的彩石金属瓦、蛭石金属瓦、彩砂金属瓦的质量会比传统的瓦片质量要轻，性能要好。
