A method of producing an L-shaped product (10) which includes an L-shaped flat top wall (12), an inside wall (14) extending and connected along an inside edge (12c) of the top wall, and an outside wall (16) extending and connected along an outside edge (12d) of the top wall, each of the inside and outside walls being terminated by flange (18, 20) substantially parallel to the top wall, is disclosed. The method comprises the steps of: providing sheet metal material; providing a drawing die assembly; and stamping the sheet metal material by the drawing die assembly to produce an intermediate product. The method further comprises the steps of: providing a bending die assembly; and stamping the intermediate product by the bending die assembly to produce an L-shaped product completed.
