What is Galvanized Steel Sheet ?

Hot-dip galvanized sheet is made by immersing the steel sheet into zinc solution at about 500 °C to attach a zinc layer to the surface. It is the most widely used and cost-effective method to process steel surfaces. Below is a workflow for your reference.

Hot dip galvanizing is the process of applying a zinc coating to cold rolled steel strip by immersing the material in a bath consisting primarily of molten zinc. The simplicity of the galvanizing process is a distinct advantage over other methods of providing corrosion protection.

Galvanizing forms a metallurgical bond between the zinc and the underlying steel, creating a barrier that is part of the metal itself. In China, the Galvanized steel coil is generally used in roofing, refrigerator door & body panels, and manufacture various parts of home appliances.

How Does Galvanization Offer Protection of Base Metal?

The basic principle of galvanization is to permanently bind the steel and zinc together to give a more rust-resistant

version of the base metal. There are various types of galvanization, each of them having its unique principles.

• The zinc coating works to prevent corrosive substances such as acid from reaching the base metal.
• Zinc sacrifices its anode more readily than the base metal when the coating is scratched. Therefore, it offers complete protection from rusting.
• Zinc corrodes faster than the base metal. This activity is a great way of protecting the base metal. Since the aim is to allow zinc rust before the metal for adequate protection, chromate can be added.

However, an effective galvanization process depends greatly on pretreatment and post-treatment. An inefficient

pretreatment will not allow the molten zinc to react with the steel for a perfect galvanized film fully. Furthermore,

an inefficient post-treatment process will compromise the appearance of the galvanized film. Thus, leading to a reduced

value of components.

Galvanized steel is used extensively across a wide range of industries due to its many advantageous properties,

which include:

• Low upfront cost
• Durable
• Resistance to rust

Galvanized steel is truly versatile with applications in almost every industry. When steel is galvanized, it’s plunged into a zinc bath, and the zinc reacts with the oxygen and carbon dioxide in the environment. Because of the thick zinc layer, the steel is greatly protected from rust and corrosion.
