This document compares and contrasts the two main types of galvanization: hot dip galvanization and electro galvanization. Hot dip galvanization involves submerging steel or iron in a bath of molten zinc, resulting in a thicker zinc coating that chemically bonds to the metal. Electro galvanization uses an electroplating process to apply a thinner zinc coating to steel through an electrochemical reaction in a zinc salt solution. The document provides details on each process and a comparison chart of the differences between hot dip and electro galvanization.

2. INTRODUCTION
▪ The process of galvanization is extremely crucial when it comes to businesses related metal industry. The
main reason being galvanization protects the metal from all natural elements increasing the longevity of the
metal. There are usually two types of galvanization that are done to metal they are Electro Galvanization and
Hot Dip Galvanization
▪ In order to understand which galvanization is better for your business, let’s take a look at how each process of
galvanization works and what are differences between them!

3. What is Hot Dip Galvanization?
Hot-dip galvanizing process is one of the most used application of galvanizing process. This process
highlights coating a steel or iron object by submerging it into a bath of molten zinc. The bath of molten
zinc showcases temperatures around 840°F (449°C). Once removed from the bath, the zinc coating on
the iron or steel’s exterior reacts with oxygen in the atmosphere to form (ZnO) Zinc oxide. This Zinc
oxide further reacts with carbon dioxide in the atmosphere to form a more compact protective layer
known as (ZnCO3) Zinc carbonate. This Zinc carbonate reflects a dull grayish film, which is relatively
stable and adheres tightly to the surface of the steel or iron. This results in the hot-dip galvanizing
process to create a chemical balance, which ensures that the zinc is chemically bonded to the underlying
metal and becomes part of the steel or metal that is being protected through the hot dip galvanizing
process.

4. What is Electro Galvanization?
Electro galvanizing is an electroplating technique used to place a layer of zinc metal on top of a steel
surface. It involves immersing a steel component into a solution containing zinc salts followed by the
application of electricity to induce an electrochemical reaction on top of the steel. The cold dip approach in
comparison to hot dip galvanization process, the electro galvanizing approach provides a thinner coating
and more aesthetic appearances method as well. The zinc-rich paints used in cold galvanizing are different
from conventional coatings due to the presence of a binding compound. These binders allow the zinc to
mechanically bond to the steel to offer an effective level of protection.
