镀铝锌材料是铝、锌合金，结构组成，由55%铝、43.4%锌与1.6%硅在600℃高温下凝固而组成，其整个结构由铝－铁－硅－锌，形成致密的四元结晶体的一种合金。其具有强的耐腐蚀性，是纯镀锌板的3倍，其表面有漂亮的锌花，由金属元素锌和铝构成材料的表面，如果锌在长时间的使用过后受到磨损时，铝便形成一层致密的氧化铝，阻止耐腐蚀性物质进一步的腐蚀内部，使材料的使用寿命更长。但是焊接性能差。镀55%铝锌合金钢板的耐腐蚀性系得自于铝的钝化层保护功能和锌的牺牲性保护功能。当锌在切边、刮痕及镀层擦伤部分作牺牲保护时，铝便在钢板外部形成不能溶解的氧化物层，发挥屏障保护功能。镀55%铝锌在世界各地区如田园地区、工业地区、一般海岸地区及严苛的海洋地区进行长期的大气曝露试验结果，证实在相同镀层厚度情况下，镀55%铝锌较镀锌耐蚀性高2-6倍。

Aluminized zinc material is aluminum, zinc alloy, structure is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at high temperature of 600℃, its whole structure is composed of aluminum-iron-silicon-zinc, forming a dense quaterchild crystal alloy. Its strong corrosion resistance, is 3 times of pure galvanized plate, its surface has a beautiful zinc, composed of metal element zinc and aluminum surface, if zinc after a long time of use by wear, aluminum will form a layer of dense alumina, prevent corrosion resistant material further corrosion inside, make the service life of the material longer. But the welding performance is poor. The corrosion resistance of 55% aluminum zinc alloy steel plate is based from the passivation layer protection function of aluminum and the sacrificial protection function of zinc. When zinc makes sacrificial protection in edge cutting, scraping and coating abrasion, aluminum will form an insoluble oxide layer outside the steel plate, playing a barrier protection function. The results of long-term atmospheric exposure test of 55% aluminum zinc plating in rural areas of the world, industrial areas, general coastal areas and harsh Marine areas, proved that the corrosion resistance of 55% aluminum zinc plating is 2-6 times higher than galvanizing.

其中屋顶用彩钢瓦也称金属瓦、镀铝锌钢板瓦，它是由镀铝锌钢板压成瓦形，表面层可用彩色陶粒或进行烤漆处理，其特点是质轻，高档，价格较高，但其给人的印象相对牢固及有安全感。也可用于钢结构或平改坡项目的使用。

Among them the roof uses color steel tile also called metal tile, aluminum plating zinc steel sheet tile, it is by aluminum plating zinc steel sheet pressing into tile shape, surface layer can be used color ceramic grain or undertake baking paint processing, its characteristic is light quality, high-grade, the price is higher, but the impression that its gives a person is relatively firm and have a sense of security. It can also be used for steel structure or flat slope projects.

选择到好的别墅建筑材料，对别墅装修起到很大的作用。只要细心甄别，货比三家，同时更多的从统一的角度去审视整个别墅的风格，就容易选择到既耐用又美观的别墅建筑材料。

Choose a good villa building materials, the villa decoration plays a great role. As long as careful screening, shop around, at the same time more from a unified perspective to examine the style of the whole villa, it is easy to choose both durable and beautiful villa building materials.
