I don't like powder coat on
steel. If you get a nick in the coating that goes down to the underlying metal,
corrosion will set in under the powder coating. Eventually, the powder coat finish lifts off in large sections. In our salty humid
environment, everything I've bought that has a powder coat finish looks like crap after a couple of years of use. Stuff that's just been painted still looks pretty good.
Haven't tried powder coat on
Aluminum or SS so don't know if it will
work better with that material.
