Abstract: A panel structure attachable to a wall, or ceiling. The panel structure may be used to mount shelf holders and utilizes a first member having first and second sides. The first side of the first member contacts the wall. A shelf standard is included for providing support for shelf holders. A backing member positions to the second side of the first member and to the shelf standard. Fastening of the backing member to the shelf standard and to the first member forms a unit. A second member, generally positioned angularly relative to the first member is positioned adjacent the backing member. Facia elements are fastened to the second member and lie adjacent the shelf standard which extends through the facia element.
