Two different types of galvanized steel pipe technology Aug 08, 2016 · Speaking of the application of steel pipe, maybe hot dipped galvanized steel pipe is a good choice and a number of manufacturers will produce it in order to occupy the steel pipe market. There are two main types when referring to hot dip galvanized steel pipe, one is hot-dipped galvanized ,the other is cold galvanized. Zinc Plated Vs Galvanized:What's the difference? WA Steel, when being hot dip galvanised is dipped into a 450°C bath of molten liquid zinc. The steel and the liquid zinc bond together because of the high temperature. The steel and the zinc become one. Zinc plating, on the other hand, is immersed in a cold chemical solution of zinc and uses an electrical current to apply a layer of zinc. The thickness of the coating is measured in microns or micrometres (m).
