Hot dip galvanized steel

The hot dip galvanizing process is where an already formed part, for example plate, round, square or rectangular tube is dipped in a zinc bath. A reaction takes place between the steel and the zinc during the time the part is in the zinc bath. The thickness of the zinc coating is influenced by a number of factors, including the surface of the steel, the time the steel is dipped in the bath, the composition of the steel as well as the steel's size and thickness.

One advantage of hot dip galvanizing is that the entire part is covered including the edges, welds, etc. giving it an all-round corrosion protection. The end product can be used outdoors in all different weather conditions. It is the most popular galvanizing method and is widely used in the construction industry.
