金属瓦在建筑行业中，起到了耐高温、耐冲击性强、耐酸性强的优势，在房屋装修过程中起到了安装方便和施工过程中简单的优势，在高档的别墅区域中使用提高了受热温度和保护了房屋中受渗水的现象出现，在使用过程中具有较高的使用寿命的价值
moment, I saw the face tilt backward with a white terror on it that I shall never forget, and heard a great cry on board the steamer and a loud splash in the water, and felt the boat sink from under me.
It was but for an instant that I seemed to struggle with a thousand mill-weirs and a thousand flashes of light; that instant past, I was taken on board the galley. Herbert was there, and Startop was there; but our boat was gone, and the two convicts were gone.
一 、彩石金属瓦在高温的使用中聚能抵抗暴风雨的袭击对房屋中起到了色彩装饰的高档实用的优势，在恶劣气候中能抵抗自然环境中的冲击能力，在使用中具有耐高温、耐候性能强的优势，成为了房屋装修中使用得最为广泛的使用性能。
二 、彩石金属瓦在使用中要进行对治疗和密度中进行监控的性能，保证了在每个产品售出中具备耐用的优势，对材料用料中要严加管理，防止使用伪劣产品的材料，导致了在施工过程中出现工作性能不稳定情况出现。
三 、彩石金属瓦在气候的照射中要进行控制紫外线的辐射性能，因为在曝晒的过程中会人体视力造成下降的影响，所以要采用隔离紫外线辐射的现象，在长期的使用中具能防曝晒和耐久性使用的优势，防止了出现老化的情况出现。彩石金属瓦的各项测试：
耐侯老化是指材料或产品对大气环境的不良反应，通常指产生不期望的，过早的破坏。主要的测试材料：塑胶材料、薄膜、电子元器件、建筑材料、涂料、家具零配件、汽车内外装饰件等。也可以是指高分子材料在加工、储存和使用的过程中，由于受内外因素的综合作用，其性能逐渐变坏，一直最后丧失其使用价值，老化是一种不可逆的变化，是高分子材料的通病，但是可以适量采取措施提高耐老化性能，延缓老化的速率，达到延长使用寿命的目的。
模拟户外或户内条件的实验室加速老化测试；耐晒褪色测试；佛罗里达亚热带气侯、亚利桑那干热气侯的直接户外暴露测试；耐臭氧老化测试。
常用测试仪器：Q-lab QUV 荧光紫外仪，Q-lab Q-SUM，ATLAS Ci4000氙灯耐侯试验箱，SUGA S80H/U48碳弧光耐侯试验箱，THE-703臭氧试验箱。
依据标准：SAE J1885/SAE J1960/ ASTM G153/154/155；ASTM D 1149/ISO 1431 GB/T 16422等。耐环境测试：能提供各类温度、温度的恒定、循环及突变测试等测试服务。
What with the cries abroad the steamer, and the furious blowing off of her steam, and her driving on, and our driving on, I could not at first distinguish sky from water or shore from shore; but, the crew of the galley righted her with great speed, and, pulling certain swift strong strokes ahead, lay upon their oars, every man looking silently and eagerly at the water astern. Presently a dark object was seen in it, bearing towards us on the tide. No man spoke, but the steersman held up his hand, and all softly backed water, and kept the boat straight and true before it. As it came nearer, I saw it to be Magwitch, swimming, but not swimming freely. He was taken on board, and instantly manacled at the wrists and ankles.
The galley was kept steady, and the silent eager look-out at the water was resumed. But, the Rotterdam steamer now came up, and apparently not understanding what had happened, came on at speed. By the time she had been hailed and stopped, both steamers were drifting away from us, and we were rising and falling in a troubled wake of water. The look-out was kept, long after all was still again and the two steamers were gone; but, everybody knew that it was hopeless now.
