镀锌钢板在正常环境下，镀锌板一般是不容易生锈的，但是假若保管不当，刮刮碰碰或多或少，水汽侵入，就极易造成生锈。此外，锌是用来保护金属的，假若锌包裹不均匀，露出了里面的金属或者也能在不经意间和其他金属发生接触，产生化学反应，也会生锈。有人要问镀锌板能保持不生锈几年，关于这个问题，还要具体看是在什么情况下，比如产地相不相同，或者镀锌板本身，比如镀锌板的锌层有多厚等等。

Galvanized steel plate in the normal environment, galvanized plate is generally not easy to rust, but if improper storage, scratch and touch more or less, water vapor intrusion, it is easy to cause rust.In addition, zinc is used to protect metals, if zinc is uneven evenly, revealing the metal inside or can inadvertently contact with other metals, chemical reactions, will also rust.Some people want to ask the galvanized plate can keep not rust for a few years, about this question, but also to see specifically in what circumstances, such as the origin is not the same, or galvanized plate itself, such as how thick the zinc layer of galvanized plate and so on.

350g/m²及以上厚锌层镀锌板具有良好的耐腐蚀性能，可以在特殊工况条件下使用，主要应用于地下波纹管涵、光伏支架、电缆桥架、大型钢板仓、工业制冷设备、畜牧业饲养设备等防腐要求极高的场所及设备，并可替代不锈钢产品，降低企业生产及使用成本。

Galvanized thick zinc layer 350g / m² and above has good corrosion resistance, can be used under special conditions, mainly used in underground bellows culvert, photovoltaic bracket, cable bridge, large steel plate warehouse, industrial refrigeration equipment, animal husbandry equipment and other high anti-corrosion places and equipment, and can replace stainless steel products, reduce the production and use cost of enterprises.

高锌层镀锌板主要用于室外防腐蚀比较高的产品或室内环境湿度比较高的产品以及产品要求防腐蚀比较高的产品。低锌层镀锌板主要用于室内管道以及民用，对防生锈不太注重的环节。

High zinc layer galvanized plate is mainly used for products with high outdoor corrosion prevention or high indoor environmental humidity and products with high outdoor corrosion prevention requirements.Low zinc layer galvanized plate is mainly used for indoor pipeline and civil use, to prevent rust does not pay much attention to the link.
