The tub es are each formed by bending a blank of steel material so as to create four 90.degree. corners with opposite ends of the blank extending parallel to each other and forming a gap along, and in the center of, an under side of the tube. A reinforcing bar is located in the gap and secured to the tube by fillet welds.
