Hot Dip Galvanizing Services

It is always frustrating to watch all your hard work, effort, and considerable expenses fall apart. This is a problem in the metal industry when steel or iron works break down due to rust and corrosion.

Rust is a real threat to many vital structures. While other coatings can be applied to protect metals, nothing beats the reliability and longevity of galvanized iron and hot dip galvanized steel. Not only does it protect the metals, but it also looks great too.

In response to a need in our community, we expanded our service from laser cutting steel and other materials to working with specialists in galvanising and other metal improvement services to ensure our clients have their masterpieces protected from corrosion and costly replacements.

What is Hot Dip Galvanizing?

Hot dip galvanizing is the process of soaking metal, iron, or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc metal and zinc-iron alloy. During the galvanizing process, a metallurgical reaction happens between the iron in the steel and the molten zinc. This reaction coats the metal, creating a diffusion process, which produces a uniform thickness throughout every part of the metal.

Galvanizing Process Steps

Cleaning the steel or iron

Before galvanising the steel, it is thoroughly cleaned by immersing the material in a highly caustic solution to remove the surface from any impurities such as dirt, oil or paint, obstructing the galvanising process.

Pickling the steel

After the material is cleaned, it is soaked and “pickled” in an acidic solution to remove the mill scale, ensuring that the surface of the steel is squeaky clean and free from any debris.

Hot dipped galvanising

Once the steel is fully prepared, it is then dipped into the bath of molten zinc. The material stays in the bath until its temperature is the same as the zinc bath itself, which is around 449 degrees Celsius, ensuring that the chemical reaction is complete.


The final step to the galvanizing process is to cool the steel inside a quench tank rather than letting it air cool. This ensures that the atmosphere doesn’t begin to interact with the material before it is thoroughly cooled.

Why Galvanize Steel

Are you looking for galvanising in Melbourne? Here are some reasons why you should start galvanising your steel.

Long-lasting assurance

Galvanising involves applying zinc covering on steel and iron to protect them from rust and your structure from disaster. If the zinc coating gets damaged, the surrounding areas will help protect the exposed area from corrosion. Small pieces of steel such as nuts, bolts and couplings are not left out of the process, even those not directly exposed to the elements. Galvanised steel and galvanized iron provide the best protection from rust. Though paint and other coats also protect these metals from rust and give it a finished look, they do not delay corrosion.
