Why powder coating should be considered for construction projects

Powder coating is popularly used to finish surfaces in the construction industry where equipment, machinery, and building materials must be durable, strong, and resistant to bumps and scratches.

Powder coating is usually used in the place of paint to finish metal surfaces.

Powder coating may be a little more expensive than liquid paint, but its robust nature makes it a much more cost-effective option in the long term.

Powder coatings can keep their appearance for up to 20 years before they begin to show signs of wear and tear. The type of powder coating used and the environment the finished product is to be used in will affect the coating’s lifespan.

Let’s find out a little more about powder coatings and why they may be the best option for your next construction project.

What is powder coating?

Powder coatings are used to give a durable and attractive finish to metal surfaces.

Powder coatings are free-flowing dry powders made up of pigments (the colour), filler materials (to make the coating smooth), and resin (to fuse everything).

The coating is usually applied to surfaces electrostatically by spraying it onto a surface and then treating it with heat or a UV light to cure the coating and fuse it to the surface.

Here at Tomburn, we provide a diverse range of powder coating products suitable for different metal types and functions. Our powder coatings can be used on aluminium, galvanised steel, mild steel, and various other substrates.

Where might a powder coating be used in construction projects?

Powder coatings are most commonly used in industries like construction, engineering, and agriculture.

This is because the highly durable nature of the coating makes it the most practical and cost-effective option for industries like these where metal surfaces may be subjected to a lot of knocks, bumps, scratches, corrosion, and extreme temperatures and weather conditions.

In the construction industry, you will find that most steel fabrications including steel beams, reinforcing bars, and steel sheets have been powder coated. Powder coatings are extremely durable and resistant to chipping, scratching, or flaking away. Steel fabrications used in infrastructure and architecture will stand in place for many years and a powder coating will help them to retain their appearance during this time.

Most metal surfaces that will be exposed outdoors for long periods can benefit from being powder coated, this includes window frames, doors, building facades, outdoor furniture, and metal fencing.

The metal parts of heavy-duty construction equipment and machinery are also often powder coated.

Benefits of using powder coating in construction projects

Still trying to decide whether a powder coating is right for your next construction project?

Read on to discover the key benefits of choosing a powder coating rather than a liquid spray paint finish.

Attractive finish

Powder coatings are available in a variety of different colours and finishes. Surfaces that have been powder coated tend to stay looking better for longer, even when subjected to extreme environments. Powder coatings are extremely strong and durable. Finishing a surface with a powder coating can help to prevent it from quickly becoming scratched, chipped, or otherwise tatty in appearance. Surfaces that have been powder coated appear sleek, shiny, and smooth. Powder-coating keeps its colour and very rarely fades.


Powder coating has several important qualities that make it much more durable, strong, and long-lasting than liquid paint. Powder coating is extremely strong and rarely ever chips or becomes scratched. It is also corrosion-resistant and weather-resistant, providing surfaces with a protective layer that is almost impenetrable.

Protective layer

As well as providing an aesthetically pleasing finish, powder coatings provide metal surfaces with a protective layer that is tough and resistant to most bumps, scrapes, and external influences. The strength and longevity of the coating provides excellent protection to the metal surface underneath, helping to reduce damage to the structure and increase its lifespan.


Powder coatings are extremely tough and durable, allowing them to withstand most wear and tear. These qualities mean that surfaces that have been coated in a powder coating tend to have greater longevity than those that have been painted. Although powder coating may be a little more expensive than paint in the short term, it is the most cost-effective option in the long term as it reduces maintenance requirements and can extend a surface’s total lifespan.

Efficient to apply

Applying a powder coating is a fast and efficient process. The powder coating is sprayed onto the material and quickly and easily provides an even coat to even the most complex and intricately shaped surfaces. Because there are no solvents involved, the process is safer, faster, and easier to clean up after.

Low environmental impact

Powder coatings are generally a more sustainable option than liquid paint. Liquid paints usually contain solvents that produce CO2 emissions that are very damaging to the environment, whereas powder coatings don’t release any solvent emissions or hazardous air pollutants. They are also free from toxic heavy metals and halogens which may be present in paint.

Safe to dispose of

Because powder coatings are free from solvents and volatile organic compounds, they do not release harmful chemicals or emissions into the environment and so are safe to dispose of at the end of their lifespan. Old powder coating that has flaked off is harmless and can be disposed of in a landfill.
