Everything You should know about Polyester Powder Coating

What is Powder Coating?

Polyester powder coating is a type of coating that is applied with a spray gun as a free-flowing, dried powder which is electrostatically charged and sprayed onto a material. The process involves coating metal in powder form and baked to a fluid state to bond it to the product’s surface, creating a protective layer. The combination of products used in the process gives the same desired look as painted finishes, and the chemicals used produces a very high-quality finish. Before coating, the parts need to be pre-treated to prepare the surface to ensure that polyester powder coating provides the highest quality result.

Why Powder Coat?

Polyester powder coating is a long-term, durable solution in comparison with traditional painting methods. The free-flowing powder makes the surface hard-wearing, with the result being more resistant to bad weather, chipping and colour fade. The high-quality finish achieved when polyester powder coating aluminium or steel provides a protective layer against corrosion, and with proper maintenance, the coating will last for a considerable period.

For many customers, the polyester powder coating colour convenience is one of the main reasons they chose this method. It’s a cost-effective way to get the exact colour and finish required that can’t always be achieved with paint.

Industries and Products:

Virtually any product across multiple industries, but predominantly metal, (steel and aluminium) have the potential to be polyester powder coated. These are just some of the main types of materials that often undergo this process. At our in-house Aberdeen facility, we often work on roofing materials such as profiled sheets, soakers, louvres and flashings.

We have supplied a number of more colourful roofing materials to coastal areas such as Skye, Shetland and the Falkland Islands. You may notice there is a lot of brightly coloured yellow, red and green roofs in these areas, all as a result of powder coating and the wide variation of colours available.

Frequently Asked Questions:

To try and clear up any unanswered questions you may have about this method of coating, our experts have outlined the most common things they get asked below:

  • Can you coat my alloy wheels? Yes, we can; however, these would need to be prepped first (either sand or shot blasted). We offer a coating service only as we only have the facilities to do so, and therefore cannot carry out the pre-treatment process.


  • How long does it take? Our turnaround for most projects is usually one week.


  • What colours can I have and what colours do you stock? We can colour match to any BS or RAL reference and can even colour match to your sample if required. We stock a wide range of colours, including 200 types of powders and finishes at our factory in Aberdeen.


  • What finishes do you have available? We can offer matt, satin (semi-gloss) or gloss.
