An apparatus for forming reinforcing structural rebar comprises: resin supply means for supplying a first resin; a first shaping die; means for impregnating a first reinforcing material with the first resin; means for pulling the resin-impregnated first reinforcing material through the shaping die to form the core of the structural rebar; material applying means for applying material for the outer cladding of the structural rebar to the core; and mold means for molding the outer cladding layer into a desired configuration on the core. The material applying means for applying the outer cladding includes means for applying an inner cladding layer over the core and means for applying an outer cladding layer over the inner layer. The inner cladding layer includes a second thermosetting resin containing a second reinforcing material, and the inner cladding layer applying means is configured so that the second reinforcing material is applied substantially unidirectionally along the longitudinal axis of the core. The outer cladding layer comprises a corrosion-resistant third thermosetting resin and a third reinforcing material contained therein.
