  • Manufacturers galvanize steel pipes by hot-dipping them by submerging the pipes in a bath of liquid zinc. This method is used because it gives a thicker layer of zinc over the base metal of the pipe. The hot-dip method is the most common method used for pipes, though there are other methods that can be used if a thinner coating of the zinc is needed, like electro-galvanization.The zinc protects th...
