金属瓦的优点
1、外形美观 色彩丰富不易褪色，造型美观立体感强，铺装后能使建筑屋面具有流畅的曲线感、凹凸有序的层次感和天然石质的厚重感，提升屋面的装饰效果，实现屋面与墙体、建筑与环境的和谐。
2、色彩多样 有十余种颜色可供选择，能充分实现屋面与墙体、建筑与环境的和谐。
3、超长寿命 采用了镀铝锌钢板、水性丙烯酸树脂、天然石粒等优质材料和特殊工艺，具有了超强的耐水、耐热、耐冻、耐光、耐腐、耐老化等性能和超长的使用寿命。
The men who sat nearest considerately turned their faces towards the other end of the field, some of them beginning to smoke; one, with absent-minded fondness, regretfully stroking the jar that would no longer yield a stream. All the women but Tess fell into animated talk, and adjusted the disarranged knots of their hair.
When the infant had taken its fill the young mother sat it upright in her lap, and looking into the far distance dandled it with a gloomy indifference that was almost dislike; then all of a sudden she fell to violently kissing it some dozens of times, as if she could never leave off, the child crying at the vehemence of an onset which strangely combined passionateness with contempt.
4、牢固安全 采用了独特的防水、防风的设计钉固安装技术，瓦和瓦之间的吻合更加紧密，瓦和屋面的连接更加坚固，使其屋面系统具有极强的抗御大雨、大雪、大风的能力。
5、施工简便 厚度和重量仅相当于普通水泥、陶土瓦的1/6左右，非常轻便，而且容易剪切和弯折，更有配套的节点配件，使安装更加简便、快捷、容易，在高层建筑和坡度很大的建筑上也可以很方便的施工。
6、经济合算 彩石面金属瓦的面积大重量轻容易搬运，采用干法作业低温季节也能施工，并使副料消耗达到了最小化，节省了搬运费用，减少了物料消耗，提高了施工效率，降低了工程造价。
7、绿色环保 全部使用绿色原料，避免了对人身及环境的污染，100%可回收再利用，是真正的环保型产品。
`She's fond of that there child, though she mid pretend to hate en, and say she wishes the baby and her too were in the church-yard,' observed the woman in the red petticoat.
`She'll soon leave off saying that,' replied the one in buff. `Lord, 'tis wonderful what a body can get used to o' that sort in time!'
`A little more than persuading had to do wi' the coming o't, I reckon. There were they that heard a sobbing one night last year in The Chase; and it mid ha' gone hard wi' a certain party if folks had come along.'
`Well, a little more or a little less, 'twas a thousand pities that it should have happened to she, of all others. But 'tis always the comeliest! The plain ones be as safe as churches - hey, Jenny?' The speaker turned to one of the group who certainly was not ill-defined as plain.
