does anyone know why square tubing isnt used for rollbars & cages ?
the only thing i can think of is its harder to bend & a little more weight
im debating on using that to build my 4 point rollbar

NHRA rules says:

All materials must be 1 3/4" O.D. X .118" mild steel or .083 4130 chromolt tubing. Except A which is 1 1/4" O.D. x .118" mild steel or .065 4130 chromoly tubing.

After building my cross member and safety loop, buy a roll ball kit and a rule book. It's not that spendy.
