A method for manufacturing a continuous stirrup and an apparatus for implementing such method are provided. The method includes placing a planar structure formed of a wave-shaped rebar on a platform, fixing a side of the planar structure and using an elongated mold to abut against the other side of the planar structure to form an intermediate structure, flipping the intermediate structure, and abutting the elongated mold against the side of the planar structure to form a continuous stirrup.
