Spiral staircase characterized in that each of its steps is made up of a prefabricated part made up of a molded monoblock given integrated by a tubular cylindrical body from which two thick plates start laterally: a horizontal one in the shape of a circular sector that constitutes the footprint and another vertical one that forms the riser arranged in a right dihedral angle that on the other end is closed by a curved vertical partition that in the front has an angular recess and in the back a heel or projection so that when superimposing some pieces on top of each other to build the staircase, these recesses and projections are assembled, and some pieces are joined together by means of an assembly of rods inserted into the axial holes of the tubular cylindrical bodies with anchorage in the foundation mass of the base.
