Powder Coating Technical Page
Why Powder Coat?
All pre-coloured products purchased from us online are powder coated as standard in house in our own powder coating plant. We only use top quality powder to coat our products. The powder coat is Architectural Grade as standard which has U.V. polymers to prevent fading from the rays of the sun.
Powder coat is a superior finish to standard paint. It is hard wearing and covers in a more uniform manner than paint eliminating drips and runs in the final finish.
Powder coating is long lasting and durable. It is resistant to chipping, scratching and fading. In addition to these benefits our powder coat is resistant to harsh environments. For example coastal facing positions.
What is Powder Coat?
Powder coating is a type of coating that is applied to a surface as a dry powder instead of a liquid paint. It is a popular method of finishing metal objects, such as automotive parts, household appliances, bicycles, and outdoor furniture, among others.
The powder coating process involves applying electrostatically charged particles of dry powder to a metal surface. The powder is attracted to the surface, creating a uniform and consistent coating that adheres tightly to the metal. The coated object is then heated in an oven, where the powder melts and forms a smooth and durable finish.
Powder coating offers several advantages over traditional liquid paint, such as better durability, resistance to chipping, fading, and scratching, as well as better protection against corrosion and weathering. Additionally, powder coating is an eco-friendly option since it produces less waste and releases fewer pollutants into the environment.
The process is undertaken on site in our workshops allowing us to control the quality of the final finish.
Powder application processes
The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a positive electric charge on the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the work piece by the powerful electrostatic charge. There is a wide variety of spray nozzles available for use in electrostatic coating. The object is then heated, and the powder melts into a uniform film, and is then cooled to form a hard coating. It is also common to heat the metal first and then spray the powder onto the hot substrate.
When powder coating we recommend that the item is galvanised prior to the coating process. Galvanising will help protect the metal underneath the coating which will prolong its service life.
As standard we supply our products primed then powder coated. You can choose to have your product galvanised when adding your product to your shopping basket.
What colours? can I have?
Products bought from our website are available in Black, White and Silver as standard. You can choose your desired colour when choosing your product.
If you wish to have an alternative colour on your product please call us to discuss your requirements. We used the RAL system when it comes to choosing a colour. The classic RAL system is used for defining standard colors for paint and coatings. RAL is the most popular Central European Color Standard used today. The colors are standard used in architecture, construction, industry and road safety. You can find out more information on by clicking here... RAL Colours
