“I sell decorative out door lighting poles & fixtures. A city I am currently dealing with has requested the poles to be anodized. I need specific reasons why powder coating would be a better finish.”
“Powder coating is not better than anodizing. They are completely different. Powder coating is an organic finish while anodizing is inorganic. Anodizing would be harder, more corrosion resistant, more durable, and would last longer than powder coating. It’s like comparing plastic to metal; no contest.
Your argument to the city should revolve around: “Better color selection, less cost, opaque vs. translucent coating, and more environmentally friendly”. Leave “better” out of the discussion.”
