ABSTRACT OF THE DISCLOSURE Lightweight scaffolding is made of aluminum or other lightweight material. The scaffolding includes end frames with vertical and horizontal frame members, the latter having special shapes for greater strength in a vertical direction with rounded top surfaces having ridges to prevent slipping. The horizontal frame members are evenly spaced to provide rungs for workers to climb. The vertical frame members are of generally cylindrical shape with thicker portions on opposite sides, the thicker portions having flat surfaces. One portion provides a full surface to which ends of the horizontal frame members are welded. The other provides a stable surface to which an adjacent end frame can be fastened. Braces can be affixed by bolt and wing nut fasteners so that a brace can be fastened to either side of the vertical frame member. Simplified connecting pins connect vertically stacked end frames. The scaffolding also includes a base to provide added width and stability, to which base vertical frame members are affixed. -17-
