CRG mostly A36 mild steel although sometimes some AR500 sneaks in. [big grin] Oxy/acetylene torch for the texture, clean it up, weld then clean it up again. I like shiny. They are then clear coated.
I have tried powder coating but didn’t like the results.
Stainless would be interesting and expensive and I’d have to have my son weld it. My tig not so good. [eek]
