Why Galvanizing?
Galvanizing is a process which is used for making the steel free from problems of corrosion. Zinc and steel are bonded together in galvanizing which makes a product which is free from corrosion. The life span of such a product made after galvanizing is 50 years. With proper care the life can be increased.
So the process of galvanizing is used to increase the life of steel. This process is used on a large scale in order to increase the life of metals. Steel is galvanized with zinc to make a strong metal which can resist the issues of corrosion for many years.
Hot-Dip Galvanizing benefits
Economical approach
Galvanizing is less costly than other forms of rust protective coatings.
Complete immersion
Hot-dip galvanizing leaves no vulnerable points for rapid corrosion, covering the surface from inside to outside.
zero-maintenance
Once done hot-dip galvanizing has long life span and does not requires any maintenance.
Durability
Zinc coating is highly durable and capable of enduring in robust conditions during the service life of steel. Galvanizing layers have also been known to secure the underlying steel for more than 50 years.
Hot-dip Galvanizing Coating Process
The coating process of galvanizing typically follows:
Pre-treatment surface preparation -> Galvanizing immersion -> Finishing
As shown below on the image below:
Process of galvanizing is completed in different steps. First step is caustic cleaning in which steel is cleaned to remove all types of impurities. Then the process of rinsing takes place. Then pickling is done and then rinsing is done again. Flux solution is used and the process of drying takes place.
Then the steel is dipped in zinc for a complete zinc bath. Then it is left for cooling and then professionals inspect the final product to make sure that there are no issues. This process is used on a large scale to make sure that the useful life of steel could be increased and it can remain safe from corrosion.
