4.1 Steel components will be delivered with a galvanized finish. Apply the powder coating finish over the galvanizing.
4.2 Powder coat the entire exterior of the component.
4.3 Powder coat the following items within the hardware kits: bolt heads, hand hole covers (if metal), and end caps for mast arms and uprights. Do not powder coat the slip base plate surface for breakaway poles.
4.4 Powder Coating Process to be completed per ASTM D7803 along with the following:
4.4.1 Remove detrimental weld flux slag deposits mechanically.
4.4.2 Protect cleaned assemblies from moisture and other foreign materials prior to prime painting. Keep indoors.
4.4.3 Brush-blast to a uniform dull appearance free of any shine.
4.4.4 Prior to the powder application, preheat the steel to a maximum temperature of 450 F for a minimum of one (1) hour.
4.4.5 Just prior to applying powder, remove moisture, oil, grease, loose paint or other foreign material using a clean rag saturated with thinner or solvent.
4.4.6 Use TGIC (triglycidyl isocyanurate) polyester powder for coating.
4.4.7 Apply powder with electrostatic spray equipment and then cure in a gas fired convection oven at a temperature range of 350 F to 400 F.
4.4.8 Provide a finished powder coat thickness of at least 3.0 mils.
