Not necessarily. There are different powdercoat products that are baked using different temperature cycles and a slew of different Al alloys that require different heat treating cycles. The manufacturer would certainly know which alloy was compatible with which powdercoat baking temperature and time. I don't think a commercial fence painter would be that sophisticated.
