Abstract: Pre-cast concrete stairs, molds for making pre-cast concrete stairs, and methods of casting pre-cast concrete stairs are provided. The stair is constructed with two beams that are cast with the stair steps as an integral monolithic structure. One of the beams (integral down edge beam) projects below the steps on one side, and the other (integral up edge beam) projects above the steps on the other side.
