Hot-dip galvanizing is essentially a process that coats steel with a protective layer of zinc alloy to protect it from corrosion. Not only is it a relatively simple and cost-effective process, but the resulting benefits will last for decades.

Preparation

First and foremost, the steel itself must be thoroughly inspected to ensure that drainage and venting requirements are met. It wouldn’t do to have a flawed product at the outset. Cleaning the Steel Prior to Hot-Dip Galvanizing

Before the galvanizing process can begin, the steel must be cleaned as thoroughly as possible. This isn’t just for appearances. The zinc coating simply can’t bond with a steel surface if foreign materials are present. There are several steps to cleaning:

The steel is submerged into a caustic tank at 180° F to remove any paint residue. It is then rinsed in a freshwater tank at ambient temperature to remove the caustic material.The steel is pickled by being dipped into a tank of heated sulfuric acid at 140°-145° F to remove any mill scale. Afterward, it is again rinsed in a freshwater tank.Lastly, the steel is washed in a flux tank containing a mixture of zinc chloride and ammonium chloride at 140°-170° F to provide protection against oxidation before galvanizing.After these steps have been completed, the steel is ready to receive its new protective coating.
