Powder coating is a dry finishing process. As such the colours available are slightly different to wet paint colours offered at you hardware store. The powder coating process first involves dipping your aluminium gate in an acid bath. Once removed and dried finely ground particles of pigment and resin are electrostatically charged and sprayed onto the products to be coated. The parts to be coated are electrically grounded, so that the charged particles adhere to them until melted and fused into a solid coating in a curing oven.
A powder coated gate looks great and the resulting finish is highly durable, meaning you will enjoy many years of your gate looking great with a little maintenance.
