I am thinking of things like bumpers and such. Learn me about the differences, and pros cons etc. I know DOM is far superior, but is pipe similar to HREW? I was talking to the guy at the place i buy steel from, and he was showing me some pretty stout 1.5, and 1.75 pipe. I was thinking of maybe using this for a front bumper. What is the downfall of using pipe. Whats the difference between pipe and HREW? I want the bumper to be for protection on the trail, but I am not out ramming stuff either. Just wondering out loud here.
