COMPOSITE PRE-CAST CONCRETE STAIR TREADS AND LANDINGS
A pre-cast concrete stair tread is provided where the stair tread has reinforced corrugated metal embedded within the core of the concrete stair tread. The corrugations are lined up along the elongated direction of the stair tread. Concrete is poured and cured over at least one side of the corrugated metal. Additionally, the pre-cast concrete stair tread may have one or more metal straps fixed on the reinforced corrugated metal in a direction perpendicular to the corrugations and the elongated direction.
