国家大力倡导彩石金属瓦屋面建材
彩石金属瓦众所周知的环保性能在防水材料市场前景越来越广阔，国家大力提倡一方面是为了环境发展的需要，另一方面也是为了整合整个防水材料市场的混乱现象，促进市场乃至整个社会的有序发展。
绿色建材在今天的建材市场的发展的如火如荼，当然，这些都是离不开国家政策的大力支持。金属彩石瓦作为一种应用比较广泛的屋面建筑材料，在防水材料市场已经占据很重要的地位，那么为什么国家这么大力倡导发展绿色彩石金属瓦呢？
`But my dear young friend,' said Mr Pumblechook, `you must be hungry, you must be exhausted. Be seated. Here is a chicken had round from the Boar, here is a tongue had round from the Boar, here's one or two little things had round from the Boar, that I hope you may not despise. But do I,' said Mr Pumblechook, getting up again the moment after he had sat down, `see afore me, him as I ever sported with in his times of happy infancy? And may I - may I - ?'
This May I, meant might he shake hands? I consented, and he was fervent, and then sat down again.
`Here is wine,' said Mr Pumblechook. `Let us drink, Thanks to Fortune, and may she ever pick out her favourites with equal judgment! And yet I cannot,' said Mr Pumblechook, getting up again, `see afore me One - and likewise drink to One - without again expressing - May I - may I - ?'
I said he might, and he shook hands with me again, and emptied his glass and turned it upside down. I did the same; and if I had turned myself upside down before drinking, the wine could not have gone more direct to my head.
在我国，南北方除了在生活习俗中的不同，在建筑环境方面也存在很大的差异，这也与南北方气候环境不同有一定的关系，南方与北方相比，多为潮湿、阴雨连绵的天气，在南方可以看到很多灰白相间或者是平屋顶屋面，而北方大多数为坡屋面所覆盖。
随着环境的不断变化以及人们生活水平的提高，在居住环境方面人们的要求也是越来越高，因此，为了适应人们在建筑保温节能、消声隔音的要求，金属瓦应运而生。
金属瓦在屋面防水方面独具特色，采用镀铝锌钢板为基板，具有很好的耐老化、防腐性能，坚固耐用，采用独特的喷砂工艺，并且经过防静电处理，能起到很好的消声隔音、自洁的效果，保证金属瓦防水、保温、耐腐蚀的性能，并且金属瓦在施工方面是非常简单的，在后期如果有损坏的瓦片，可以单片进行更换，不会影响屋面的整体结构。
随着技术的发展，现在的彩石金属瓦业发展出不同的类型与颜色，一般建筑上面用的比较多的像丽波瓦（七波）、丽波瓦（九波）、大师瓦(中国红)、至尊瓦（海洋蓝），具有十几种颜色可以供大众进行选择，并且本身瓦片的柔韧性好、易裁切，可以用于屋面脊瓦、斜脊等部位的裁切，经济合算，不会造成资源浪费。
Mr Pumblechook helped me to the liver wing, and to the best slice of tongue (none of those out-of-the-way No Thoroughfares of Pork now), and took, comparatively speaking, no care of himself at all. `Ah! poultry, poultry! You little thought,' said Mr Pumblechook, apostrophizing the fowl in the dish, `when you was a young fledgling, what was in store for you. You little thought you was to be refreshment beneath this humble roof for one as - Call it a weakness, if you will,' said Mr Pumblechook, getting up again, `but may I? may I - ?'
It began to be unnecessary to repeat the form of saying he might, so he did it at once. How he ever did it so often without wounding himself with my knife, I don't know.
`And your sister,' he resumed, after a little steady eating, `which had the honour of bringing you up by hand! It's a sad picter, to reflect that she's no longer equal to fully understanding the honour. May--'
I saw he was about to come at me again, and I stopped him.
