Galvanization is a manufacturing process involving the application of zinc coating to steel to prevent it from rusting. The zinc coating works to protect the base metal. It does this by acting as a barrier to the various corrosive elements. Therefore, it offers a sacrificial nature that gives a high-quality and long-lasting steel product.
Galvanized sheet metal is one of the most popular types of steel. This is due to its increased strength, extended durability, and formability. The corrosion-resistant property throws its usefulness up a significant notch.
| Types Of Galvanizations |
There is a wide variety of galvanization types for corrosion protection. Each of these types has its unique performance
and characteristics.
Following is a brief description of the various types of galvanizations. |
| Hot-Dip Galvanization |
Hot-dip galvanization is the most widely used method of galvanization. Just as its name suggests, it involves the dipping of the steel in molten zinc.
The pool of molten zinc often maintains a temperature of about 860°F (460 °C).
After proper cleaning of the base metal chemically, it gets fluxed to eliminate residual oxides.A metallurgical bond begins to form between the zinc and the intended metal. After pulling the metal from the bath, the pure zinc mixes with oxygen from the atmosphere to form zinc oxide. Then, the zinc oxide reacts with carbon dioxide to form zinc carbonate. The zinc carbonate makes the final coating on the base metal. |
| Electro Galvanization |
Unlike the hot-dip method, this type does not use a molten zinc bath. Rather,
it uses an electrical current in an electrolyte solution to transfer the zinc ions into the metal.
The positively charged zinc ions are reduced electrically and deposited on the charged material.
It offers the benefit of precise and uniform coating thickness. |
