Many corporate customers who understand steel products, it will be easier to choose, use all kinds of steel products, however, many customers report that, what are the white powders on u shaped steel?

Whether it is u shaped steel or other steel, it is generally shorter in the air, it is not going to oxidize. But it has a galvanized coating on its surface, so in the presence of air or other media, it is going to oxidize, this produces a white zinc oxide powder. And the white powder that friends say is zinc oxide powder, I’m sure a lot of friends would like to know that is this problem serious? As for the severity, what do you need to do, this still depends on the degree of oxidation?
