Why are the bollards powder-coated and not painted?

The process used for powder coating or creating a baked enamel finish has a number of advantages over classic wet painting. It offers great resistance to impacts and chemical effects (e.g. dog urine, de-icing salt, etc.). Baked enamel finishes are also more environmentally friendly, as they produce virtually no by-products during baking, and contain no toxic, odorous or flammable solvents.
