I have been looking for a small supply of roll formed steel to use on converting a bus into a motor home. Back when I was in high school the called it cold rolled. I haven't used the stuff for 40 years now the people at the steel yards look at me like I am asking for moon rocks. the structural angle and channel is too heavy to use and wont fit with what the bus is made out of. It is a 2008 Champion 25 footer on an F450 chassis. What I need to know is who supplies standard roll formed steel, or if I am searching for the wrong thing (is it called something else now)? TIA JH. PS. I am new to the forum, so if I posted this in the wrong place I apologize.
