pitching the metal sheet forward so as to position a second section of the metal sheet in the stamping press;
conducting a second stamping operation using the stamping press to form a second frame segment in the second section of the metal sheet, the second frame segment including another portion of the support strip and another column extending from the support strip, wherein the second frame segment is adjacent to the first frame segment so as to form a line of columns extending from the support strip; and
cutting the frame segments from the metal sheet so as to form the frame.
