The metal to be galvanized is cleaned to
remove any rust, scale, or other contaminants from its
surface. This is typically done through processes like
pickling, where the metal is immersed in a solution of acid,
or abrasive blasting.
Galvanizing Process
What is Galvanizing Process?
The galvanizing process is a method used to
protect steel and iron from corrosion by applying a protective layer of zinc to the
surface of the metal. This process is known as "hot-dip galvanizing" and involves
several steps:
-
Surface Preparation
-
Fluxing
-
Galvanizing Bath
-
Withdrawal
-
Quenching
-
Inspection
Hot-dip galvanizing is widely used in various industries, particularly in construction, to protect steel structures and components from corrosion. The zinc coating acts as a sacrificial layer, corroding in preference to the underlying steel or iron, thus extending the lifespan of the metal and reducing maintenance requirements.
It's important to note that there are other methods of galvanizing as well, such as electro-galvanizing, which uses an electrolytic process to deposit zinc onto the metal surface, and mechanical galvanizing, which involves tumbling the metal with zinc powder and glass beads to achieve a zinc coating. These methods are used for different applications and offer varying levels of protection.
