Powder coating is what is called a dry finishing process. As such the colours available are slightly different to wet paint colours offered at you hardware store however, the range of colours and finishes available is still vast.
The powder coating process first involves dipping your aluminium gate in an acid bath. This is a critical step in the powder coating process, and one that cannot be rushed given it is fundamental in achieving a consistent quality finish. Once removed and thoroughly dried, finely ground particles of pigment and resin are electrostatically charged and sprayed onto the products to be powder 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.
Advantage of Powder Coating
