Mine is made out of heavy box section tubing, when I went to have them made they asked me what I wanted to do with it, I explained and they said that it was far too strong for this application. So I used it

And it works fine, took a collision at a speed of about 50mph with the bumper mounted to the blocks and I didn't bent the mounts (just almost everything else around it).
The car was financially total loss, fixed it for $300 got around $1600 for it and bought a nice winchbumper and lift kit for it
