寶鋼彩鋼瓦基板種類：1.鍍鋅彩鋼瓦是以鍍鋅鋼板為基板的彩色涂層鋼板，鋅層上的涂層起到覆蓋隔離作用，可以防止鍍鋅板生銹，從而延長鍍鋅

鋼板的使用壽命。目前比較公認的鋅比大于100能有效防止彩鋼瓦切口腐蝕。就是說0.6mm的彩鋼瓦，單面鍍鋅量要達到60克/平方米。實踐表明，

鍍鋅彩涂板在堿性環境中的表現優于鍍鋁鋅彩鋼瓦。所以說在特殊環境中，鍍鋅彩鋼瓦還是有自己的優點。

Baosteel color steel tile substrate type: 1. Galvanized color steel tile is a galvanized steel plate as the substrate of the color coating steel plate,

the coating on the zinc layer plays a cover isolation role, can prevent the galvanized plate rust, thus extending the service life of the galvanized steel plate.

At present, the relatively recognized zinc ratio greater than 100 can effectively prevent the corrosion of color steel tile incision.That is to say, 0.6mm color

steel tile,a single surface galvanizing amount should reach 60 grams / square meter.Practice shows that the galvanized color coating plate performs better than

the aluminum galvanized color steel tile in the alkaline environment.So in a special environment, galvanized color steel tiles still have their own advantages.
