Powder Coating vs. Liquid Paint in Sheet Metal Fabrication: Which Finish Is Right for Your Project?
When specifying finishes for fabricated metal components, one of the most common questions engineers and procurement teams face is: powder coating or liquid paint? Both finishing systems provide corrosion protection, aesthetic value, and surface durability — but their performance characteristics, cost structures, and application methods differ significantly.
