Vertical supports stand alone at the wall edges but they are bolted back-to-back along the center of the wall. (2) Steel I-beam horizontal cross members connect the vertical supports. (3) 3"x3"x1/4" angle (L-shaped) steel members create a frame onto which the chamber panels are bolted. These 3"x3" angle members are welded to each other and welded to the vertical supports.
