養殖場為了更快速的投入生產，很多農戶選用彩鋼瓦直接鋪設在房梁上，簡單快捷，省心省力。彩鋼瓦就是彩涂板，

就是在薄薄的鋼板表面鍍鋅或鍍鋁鋅，在鋼板生成一層防腐蝕鍍層，然后再在鋼板鍍層上涂上PE等防腐蝕涂料。很多人選購彩鋼板時，

很容易忽視鍍層的厚度。常規來看，鍍層厚度越大，耐腐蝕性能越好。鍍層厚度主要是影響到彩涂鋼板的切口腐蝕性能，切口腐蝕是電化學腐蝕，

影響因素有預處理層、底漆、基板厚度、鍍層厚度等。在正常情況下，預處理層和底漆相對比較固定，

影響切口腐蝕性能的就是基板厚度及鍍層厚度了。

In order to put into production more quickly, many farmers choose color steel tile directly laid on the beam, simple and fast, save worry and effort.

Color steel tile is the color coating plate, it is in the thin steel plate surface galvanizing or aluminized zinc,

in the steel plate to generate a layer of anti-corrosion coating, and then in the steel plate coating coated with PE and other anti-corrosion coating.

When many people buy color steel plate, it is easy to ignore the thickness of the plating layer. Generally speaking, the larger the coating thickness,

the better the corrosion resistance. The coating thickness mainly affects the incision corrosion performance of the color coated steel plate.

The incision corrosion is the electrochemical corrosion, and the influencing factors include the pretreatment layer, the primer, the substrate thickness,

the coating thickness and so on. Under normal circumstances, the pretreatment layer and the primer are relatively fixed,

and what affects the corrosive performance of the incision is the thickness of the substrate and the thickness of the coating layer.
