After fabrication, the surface of the steel is shotblasted clean to remove all rust deposits prior to application of the primer. A zinc rich epoxy based powder primer is used which is formulated to increase the corrosion resistance of shot blasted steel when applied before powder coating.

Powder coating is applied using electrostatic spraying where the paint solids are sprayed onto the product in an atomised powder form and then heated in an oven to 160 - 210 degrees. The powdercoating produces a continuous film over the steel to form a uniform, solid, smooth, tough and resilient coating.
