Powder coating is a method of applying a protective layer on top of steel posts and rail fencing and other substrate surfaces. Unlike paint, powder coating doesn’t contain solvents and is applied in solid form. It adheres through a heat-binding process.
Powder coated steel is typically made up of iron, carbon and other materials which can rust. To prevent corrosion, the base material steel can be powder coated with finely ground particles of pigment and resin. Powder coating is applied as a dry powder on the steel.
