：彩石金属瓦具有多种性能。例如颜色丰富，外形美观，防身自洁等多方面的优点。因为各方面性能优势，彩石金属瓦适用于别墅、小区、博物馆等各种建设中。经过建筑实践检验，彩石金属瓦的使用寿命相当长。 金属落水系统不但排水的功能强大，更主要的是装饰效果也不错，金属落水系统具有很好的抗紫外线性能、耐侯性极佳、不氧化、不腐蚀、不会污染墙面。常用的落水系统的配件附件都比较齐全，并且采用有组织排水，这样对绿化有很好的保护作用，避免了自由落体的污水污染墙面，导致影响美观。
防水是利用防水材料的致密性、憎水性构成一道封闭的防线，隔绝水的渗透。排水是利用水向下流的性，不使水在防水层上积滞，尽快排除。防水排水相辅相成，排水可以减轻防水的压力，防水又为排水提供了充裕的排除时间。所以既要“防’，又要“排”。只排水而不防水，在降水的短时间内就会渗漏。只防水而忽视排水，认为防水材料好，不怕水浸，积水数日，防水层也会溶胀，起鼓、裂缝。尤其胶粘剂合缝的材料，因积水久搔，会造成粘结强度降低，开胶绽缝。
为此，屋面坡度不得小于2％，目的就是保证排水通畅。为了减少雨水在屋面停留的时间，通常要缩小汇水面积（200m2），增加水落口数量加大排水管的直径。为了防止暴雨积水，在排水口设虹吸式排水装置。地下建筑设盲沟降水，种植屋面在土层下设排水层，都是防排并举的实用原则。
一、金属瓦的使用寿命与质量息息相关。任何产品的使用性能再优异，用不了多久就坏了，那么这个产品就不具有实用性。金属瓦也是如此，金属瓦如果瓦片易碎裂容易坏的话就会对屋面造成很多影响，后期的更换也带来诸多麻烦。所以用户对金属瓦的寿命分外关注。正规金属瓦生产厂家生产的经过金属瓦国家标准检验的，可以保持相当优异的质量与长久的使用寿命，为客户避免很多不必要的麻烦。
二、彩石金属瓦使用寿命与材质有重要关系。普通钢板的使用寿命一般只有10余年，镀铝锌钢板具有很强的耐热性，在气候恶劣的沿海地区更能有效地耐腐蚀，使用寿命可长达50年。提高了瓦片的抗腐蚀性能、防水防风性等多方面的性能。并且由于如今生产工艺的改进，设备日趋精密化，正规厂家出厂的金属瓦质量大大提高，同样延长了金属瓦的使用寿命。
彩石金属瓦作为一种使用寿命比较长的产品，使用年限超过了很多其他材质的屋面瓦。此外金属瓦的柔韧性强不易破碎，正确的金属瓦施工方法也可以延长瓦片的使用寿命，为日常居住减去后顾之忧。这种方法最A常见的方法是软文推广，在百度上提问题的时候，有时会看到一些类似于详情请查看……的语句，这就是综合推广。"However determined you are to lead a different kind of existence, Armand, who loves you, will never agree to the retiring life which his modest means would force you to live, for seclusion is no state for beauty like yours. Who knows what he might do! He has already taken to gambling once, as I discovered, and without saying anything to you, as I further discovered. But in a wild moment, he could easily have lost part of what I have been putting aside this many a year for my daughter's dowry, for him, and for the peace of my old age. What might have happened once might still happen.
"Besides, can you be sure that the life you'd be giving up for him would never attract you again Are you certain that, having fallen in love with him, you would never fall in love with anyone else And, not least, will you not suffer when you see what limitations your affair will set upon your lover's life You may not be able to console him as he grows older if thoughts of ambition follow the dream of love. Reflect on all these matters, madame. You love Armand. Prove to him in the only way now open to you by sacrificing your love to his future. Nothing untoward has happened thus far, but it will, and it may be much worse than I anticipate. Armand may become jealous of some man who once loved you; he may challenge him to a duel, he may fight, he may even be killed, and consider then what you would suffer as you stood before a father who would hold you accountable for the life of his son.
