Not coated, dipped and then media blasted. I am coating myself using the patience and rattle can method.
I think alloys are more expensive than steel, no need to dip I was informed.
I had some steel ones off my horsebox done for a tenner each and then painted myself, this was by a different company down south.
Blasting very much worth the cash, not sure about powder coating, anyone got an opinion on that?
