Powder coating is one way to change the colour of your door hardware to match current trends.

Powder coating is a powder based paint that is baked onto the metal. The powder coat does gives a thick hard durable finish. Warranty on powder coat can be 2 years plus, however the warrenty oncly covers separation from the metal.

It is important to remember that powder coat is still just a paint. And as such it is suceptible to chipping, scratching, and deterioration over time.

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 coating and is then cured under heat to allow it to flow and form a "skin".

We do offer an Epoxy Powder Coat finish which is more durable than standard powder coating. The process takes 2 -3 weeks to complete. Colour range is restricited. Although Matt Black is avilable. Epoxy powder coat is more hard waring and should last longer than standard powder coat.


The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware and automobile and bicycle parts.

Because powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces.

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 to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the workpiece by the powerful electrostatic charge

When a thermoset powder is exposed to elevated temperature, it begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure. This cure process, called crosslinking, requires a certain temperature for a certain length of time in order to reach full cure and establish the full film properties for which the material was designed.


Cleaning of powder coating should be at best no more than warm water, dish washing liquid, and a clean cloth. Any chemical application can and will harm the paint surface.

It is advisable not to rub or use any form of scourer on the surface as this will damage the surface.
