現時我國工業越來越多廠房通行采用彩鋼瓦做屋頂材料，起到遮陽、防水功能。此類彩鋼瓦，基材均是鋼鐵，表面處理為鍍鋅、鍍鋁鋅，

再噴漆處理。之所以大多數廠房采用彩鋼瓦，是因為彩鋼瓦價格相對便宜。一般彩鋼瓦基板都是鍍鋅基板，

如果客戶有特殊要求使用鍍鋁鋅基板也是可以定制的。一般情況下的基板厚度為0.02mm-0.05mm，

一般情況下基板的含鋅量會直接影響彩鋼瓦生銹程度，佛山市萬慶物資使用的寶鋼彩涂卷壓制成的彩鋼瓦含鋅量高，耐銹能力也高。

At present, more and more factories in China's industry use color steel tile as roof material, play a shading, waterproof function. This kind of color steel tile,
