Galvanizing is an art.

Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent premature rust and corrosion.

Degreasing/Caustic Cleaning

First the steel is immersed in an acid degreasing bath or caustic solution in order to remove the dirt, oil, and grease from the surface. After degreasing, the steel is rinsed with water.


The steel is then immersed in an acid tank filled with either hydrochloric or sulfuric acid, which removes oxides and mill scale. Once all oxidation has been removed, it is again rinsed with water.


The purpose of the flux is to clean the steel of all oxidation developed since the pickling of the steel, and to create a protective coating, before entering the galvanizing kettle.

Zinc Bath

Steel is now ready for immersion in the molten zinc. The steel products remain in the kettle until the temperature of the steel has reached the temperature required to form a hot-dip galvanized coating.

Post Treatment

Once removed from the kettle, it may receive a post-treatment to enhance the galvanized coating. One of the most commonly used treatments is quenching. Other finishing steps include removal of zinc drips, by grinding or filing them off.

Proper Drainage and Venting

The primary reason for vent and drain holes is to allow air to be evacuated, permitting the object to be completely immersed into cleaning solutions and molten zinc. Proper sizing and location of the holes make it safer to galvanize and provide and optimal finish. The secondary reason for venting/drainage is to prevent damage to the parts.

Sustainable Development

Sustainable development involves balancing local and global efforts to meet basic human needs without destroying the natural environment.

With hot-dip galvanizing, zinc coatings lengthen the life of steel structures by keeping steel performing in its optimal condition. This benefit alone enables a huge preservation of natural resources by reducing waste that occurs naturally. As a result, steel and zinc both serve as sustainable materials in today's environmental conscious society.

Dedicated To Our Environment

At Supreme Galvanizing we want to do our best when it comes to protecting our environment through the utilization of special equipment such as: an air scrubber system (control gaseous emissions) or including a waste water treatment system (clean and recycle our water usage). We ensure our success to staying green.
