At this stage, there is no more effective way to combat rust than coating metal products with a zinc layer. In the abundance of modern methods of galvanizing, the most reliable is still the method of hot-dip galvanizing. Invented in the mid-eighteenth century, it still remains the most reliable and popular in the galvanizing environment.
Hot dip galvanizing is applicable for welded pipe structures. Often, the seam formed during welding is the weakest point of the metal product, so it needs additional protection. When galvanizing structures of this kind, the weld is pre-cleaned, as in some cases there may be incompatibility of metals, and zinc will be rejected. After galvanizing will increase not only the strength of the product, but also the strength of the bond. Unfortunately, when using this method, the decorative features of the welded pipe structure will fade into the background, as there is a high risk of leaks on the weld and around it. But the main thing-reliability in use!
