冷镀锌方管是在所用的方管上利用冷镀锌的原理来使方管具有防腐蚀的性能。与热镀锌不同冷镀锌涂料主要通过电化学原理来进行防腐，因此必须保证锌粉与钢材的充分接触，产生电极电位差，所以钢材表面处理很重要。

Cold galvanized square tubes are used to make square tubes have anticorrosive properties by using the principle of cold galvanizing. Different from hot-dip galvanizing, cold-dip galvanizing coatings are mainly anti-corrosion based on electrochemical principle. Therefore, it is necessary to ensure full contact between zinc powder and steel to produce electrode potential difference, so surface treatment of steel is very important.
