Powder coating is a treatment to help steel last longer and look better. It involves spraying polyester powder onto
steel, with an electrostatic gun, and then baking it in an oven. The powder melts together and forms a skin. This skin is
a much better coating than ordinary paint, lasting longer and resisting scratches better.
Powder Coating has several advantages over conventional liquid coatings (paints):
Powder coatings emit zero or near zero volatile organic compounds (VOC).
Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.
Powder coating production lines produce less hazardous waste than conventional liquid coatings.
Capital equipment and operating costs for a powder line are generally less than for conventional liquid lines.
Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces.
