1" box/tube 1.5 or 2mm wall should be strong enough. You'd probably want to gusset the corners. Also has the bonus of not bouncing a ball straight back out (tried it before)
We didn't gusset the corners for the LO goals, i think it is unnecessary.
Something to ping the ball up would be good though.. maybe a smaller od pipe attached on the inside of the back of the goal.
