Its 2 50"s long 2-1/2 x 2-1/2 x 3/16" wall square tubing stacked on top of each other , welded together the entire length of the seem front and back and angled off at the ends. Should be pretty tough.... well should be anyway. Total cost of the entire bumper is $15 bucks. Including gas, welding rods, electricity, steel, and paint. Score me.:flipoff2:
