“How does powder coating compare to zinc plating in terms of salt spray and application cost?”


“Powder Coating is an organic coating that will never achieve the salt spray resistance of zinc plating, an inorganic material. It’s like comparing paint (powder) to metal (plating). Application costs all favor powder coating, which is much cheaper to purchase and apply. Further, powder coatings do not have any environmental problems, normally associated with plating. This further reduces the overall cost of applying powder coatings. It comes down to price vs. performance…plating costs more but provides better corrosion resistance than powder coating. Powder coating can achieve salt spray resistance of up to 1000 hours over galvanized substrates and 500 hours over mild steel.”
