METHOD FOR PRE-TREATING A GALVANIZED FENCE PANEL FOR COATING
The present invention relates to a method for pre-treating one or more galvanized fence panels to be coated, wherein the one or more galvanized fence panels are sequentially immersed in baths in a suspended state, wherein the method comprises the following sequential steps: degreasing, whereby the fence panels are immersed in a degreasing bath containing a degreasing agent; rinsing, wherein the fence panels are immersed in a first rinse bath comprising water; pickling, whereby the fence panels are immersed in two successive pickling baths containing pickling agents; rinsing, wherein the fence panels are immersed in a second rinse bath comprising water; demi-rinsing, whereby the fence panels are immersed in a demi-rinse bath containing demineralized water; applying an adhesion layer, wherein the fence panels are immersed in a polymer bath; and wherein the fence panels are subsequently dried in an oven, and wherein the pickling agents comprise hydrogen fluoride and phosphoric acid, in a ratio between 1/320 and 1/80.
