We can galvanize unequal angle steel. Corrosive liquid or gas will cause great damage to unequal angle steel. We must avoid these sources of corrosion when using. Once galvanized, it is equivalent to adding a protective umbrella to unequal angle steel, which can effectively protect unequal angle steel from corrosion of these corrosive objects, so as to increase the corrosion of unequal angle steel service life. In addition, we can extend the service life of unequal angle steel by bing antirust paint. However, the protection effect of this method is not as significant as galvanizing, so there are not many related applications
