Powder coating

Powder coating of galvanised steel, also called “duplex treatment” is a GALVA UNION Group strenght.

Powder coating consists in applying powder paint to a metallic part which has gone through prior preparation, then heating it in an oven.

Life duration of the covering

To make sure the powder-coated lasts as long as possible, it is important to follow these 5 essential phases:

  • 1. De-oxidise the zinc through chemical pickling

  • 2. Rinse the part to be treated fully

  • 3. Extract gas

  • 4. Protect the zinc underneath the paint by film-forming conversion

  • 5. Apply the finishing layer through powder coating

The quality of the powder coating also depends on the technical characteristics of the powder. The use of architectural quality polyester powder paint allows us to offer the nest long-lasting characteristics for outside environments.
