A peg board panel for supporting a bracket or other generally available hanging element. The panel is comprised of a fabricated metal panel having a front surface, a side surface, a rear surface, and an array of holes extending through the panel. The holes are first punched and then extrusion formed to create an upstanding annular flange extending away from the rear surface of the panel by a predetermined distance or extent. A bracket having a hook is supported by the panel by extending the hook through the hole. The annular flange strengthens the panel and provides a rigid support for the bracket. The hook also has an extent which is equivalent to the predetermined extent of the flange so that no play exists between the bracket and the panel, eliminating brackets that sag or pull out of the panel. The panel diametrical hole sizes and spacing can be varied along the panel.

[ What is claimed is:] [1.] A process for forming a metal panel used in the construction of shelving units, said panel having a longitudinal axis and formed from a metal sheet blank having a pair of spaced longitudinal sides interconnected to a pair of spaced vertical sides, said sheet blank sides delimiting a top and bottom surface of said panel, the process comprising the steps of:providing at least one row of pilot hole punches and corresponding dies relative to one of said vertical sides of said sheet blank;providing at least one row of extrusion punches and corresponding dies relative to one of said vertical sides of said sheet blank;providing at least one row of extrusion punches and corresponding dies in parallel arrangement to said pilot hole punches and dies, said sheet blank generally interposed between said pilot hole punch and dies and said extension punch and dies;advancing said sheet blank such that said one vertical side lies under said pilot hole punch and dies;executing a part of said pilot hole punch and dies to punch form a row of pilot holes into said sheet blank, said row of pilot holes extending across said sheet blank, parallel to said vertical sheet side;advancing said sheet blank so that said row of punched pilot holes is aligned under said extension punch and dies;executing a part of said extension punch and dies which correspond to said number of pilot holes, whereby an amount of sheet blank material surrounding each of said pilot holes is drawn through each respective pilot hole and into each of said executed extrusion dies such that an upstanding annular flange is extrusion formed about each of said pilot holes, said row of extruded holes adding structural strength to said panel;successively advancing said sheet blank through said other part of the pilot and extrusion punch and dies such that a series of rowed pilot holes and extruded holes are formed in said sheet blank between said vertical sides.
