鍍鋁鋅材料是鋁、鋅合金，結(jié)構(gòu)組成，由55%鋁、43.4%鋅與1.6%硅在600℃高溫下凝固而組成，其整個(gè)結(jié)構(gòu)由鋁－鐵－硅－鋅，形成致密的四元結(jié)晶體的一種合金。其具有強(qiáng)的耐腐蝕性，是純鍍鋅板的3倍，其表面有漂亮的鋅花，由金屬元素鋅和鋁構(gòu)成材料的表面，如果鋅在長(zhǎng)時(shí)間的使用過(guò)后受到磨損時(shí)，鋁便形成一層致密的氧化鋁，阻止耐腐蝕性物質(zhì)進(jìn)一步的腐蝕內(nèi)部，使材料的使用壽命更長(zhǎng)。但是焊接性能差。鍍55%鋁鋅合金鋼板的耐腐蝕性系得自于鋁的鈍化層保護(hù)功能和鋅的犧牲性保護(hù)功能。當(dāng)鋅在切邊、刮痕及鍍層擦傷部分作犧牲保護(hù)時(shí)，鋁便在鋼板外部形成不能溶解的氧化物層，發(fā)揮屏障保護(hù)功能。鍍55%鋁鋅在世界各地區(qū)如田園地區(qū)、工業(yè)地區(qū)、一般海岸地區(qū)及嚴(yán)苛的海洋地區(qū)進(jìn)行長(zhǎng)期的大氣曝露試驗(yàn)結(jié)果，證實(shí)在相同鍍層厚度情況下，鍍55%鋁鋅較鍍鋅耐蝕性高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.

其中屋頂用彩鋼瓦也稱(chēng)金屬瓦、鍍鋁鋅鋼板瓦，它是由鍍鋁鋅鋼板壓成瓦形，表面層可用彩色陶?；蜻M(jìn)行烤漆處理，其特點(diǎn)是質(zhì)輕，高檔，價(jià)格較高，但其給人的印象相對(duì)牢固及有安全感。也可用于鋼結(jié)構(gòu)或平改坡項(xiàng)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.

選擇到好的別墅建筑材料，對(duì)別墅裝修起到很大的作用。只要細(xì)心甄別，貨比三家，同時(shí)更多的從統(tǒng)一的角度去審視整個(gè)別墅的風(fēng)格，就容易選擇到既耐用又美觀的別墅建筑材料。

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.
