    Abstract: A corrosion resistant PC steel stranded cable for a pretensioning method has a core wire and a plurality of side which are coated firmly for the corrosion proof with paint of a synthetic resin material while maintaining a stabilized stranded condition. The cable comprises the single core wire and the plurality of side wires disposed in a closely contacting relationship with each other and also with the core wire in such a manner as to define a plurality of spiral air gaps between the core wire and the side wires and also to define a plurality of spiral recessed grooves between individual adjacent ones of the side wires on the outer side of the side wires. Each of the core wire and the side wires are processed by blueing in advance. Paint of a synthetic resin material is filled in the spiral air gaps, and a coating layer of paint of a synthetic resin material is formed substantially with a uniform thickness on an entire outer periphery of the side wires including the spiral recessed grooves. A process of and an apparatus for producing such corrosion resistant PC steel stranded cable are also provided.
