A hanging rod to hang a file folder, the hanging rod comprising:
- a first end;
- a second end opposite the first end;
- outer flanges extending between the first end and the second end;
- a middle portion between and protruding from the outer flanges, the middle portion having an M-shaped cross-section to increase a rigidity of the hanging rod;
- and
- a first notch adjacent the first end and a second notch adjacent the second end that enable the hanging rod to hang from a support structure.
A method comprising:
- forming holes in sheet stock adjacent edges of the sheet stock to form notches defined by a first hanging rod and a second hanging rod, the notches to enable the first hanging rod and the second hanging rod to hang from a support structure;
- cutting the sheet stock to define outer edges of the first hanging rod and the second hanging rod;
- stamping the sheet stock to form:
- a first middle portion between first outer flanges of the first hanging rod, the first middle portion having an M-shaped cross-section to increase a rigidity of the first hanging rod;
- and
- a second middle portion between second outer flanges of the second hanging rod, the second middle portion having an M-shaped cross-section to increase a rigidity of the second hanging rod;
- and
- separating the first hanging rod and the second hanging rod.
