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 Akzo Nobel 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 coat is a type of finish coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. Powder coat is also more durable than a standard painted finish.

The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals.

The process is undertaken off site from our workshop. Our powder coating partner is one of the U.K’s leading suppliers, whose customer portfolio includes some of the countries leading companies. This guarantees quality of finish and turn around times.

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
