金屬聲屏障的材料包括鋁合金板、鍍鋅板、鐵板等。鐵板很容易在潮濕的空氣中氧化生銹，在生產(chǎn)和使用過程中造成不便，所以鐵板人們很少采用。鍍鋅板以其優(yōu)良的性能和適中的價格比，被廣大客戶接受。

The materials of the metal sound barrier include aluminum alloy plate, galvanized plate, iron plate, etc. Iron plate is easy to oxidation and rust in humid air, in the process of production and use of inconvenience, so people rarely use iron plate. Galvanized sheet with its excellent performance and moderate price ratio, is accepted by the majority of customers.

鋁合金板也稱鍍鋁鋼板，也有人稱之為滲鋁板或熱浸滲鋁板，其中鋁含量為90%，硅10%。其它元素還有銅、鎂、鋅、錳等。鍍鋁比鍍鋅更具優(yōu)越性，鍍鋁層不僅具有比鍍鋅層好得多的耐蝕，而且還有良好的耐高溫氧化性，這些都是鍍鋅層所比不上的。由于鍍鋁鋼板的性能優(yōu)越，已被廣泛應(yīng)用于我們的日常用品之中，如汽車消聲器、家用電器等。

Aluminum alloy plate is also known as aluminum plating steel plate, also called seepage aluminum plate or hot soaking aluminum plate, the aluminum content is 90%, silicon 10%. Other elements include copper, magnesium, zinc, manganese and so on. Aluminization is more superior than galvanized layer. Aluminized layer not only has much better corrosion resistance than galvanized layer, but also has good high temperature oxidation resistance, which are not comparable to galvanized layer. Due to the superior performance of aluminum plating steel plate, it has been widely used in our daily supplies, such as automobile muffler, household appliances, etc.

 鋁合金板的表面易自然生產(chǎn)一層致密牢固的AL2O3保護膜，這層保護膜能很好的保護基體不受腐蝕。通過人工或機器噴涂后，能很好的著色，可以保持20年不褪色，所以采用鋁合金板制作的冷卻塔聲屏障使用壽命更長久。

The surface of aluminum alloy plate is easy to naturally produce a layer of dense and firm AL2O3 protective film, this protective film can well protect the matrix from corrosion. After manual or machine spraying, it can be very well colored and can be kept fast for 20 years, so the sound barrier of the cooling tower made of aluminum alloy plate has a longer service life.
