Powder Coating

Powder coating is a modern, more environmentally-friendly alternative to traditional wet painting. Minute powder particles are applied to a metal object or component using an electrostatic spray process, which causes the powder to adhere to the metal surface. After spraying, the component is cured in an oven at up to 200°C. This process then melts the powder onto the metal creating a highly finished and durable coating.

The finished product is very aesthetically pleasing and is less prone to to chipping, marking and scratching.

The powder coating process is faster than traditional wet painting where the product must dry between coats. With powder coating, the product is oven baked, so there is no need to wait for drying.

Powder coating is a more environmentally-friendly process, as powder can be recycled.

Powder coating can be applied to a wide range of metals and components and is suitable for both internal and external applications.
