    Abstract: A corrosion-protected tension member of steel composed of a plurality of individual wires twisted into a strand, wherein each of the individual wires of the strand is composed of a steel wire freed from deposits by a surface treatment and surrounded by a continuous sheathing of a corrosion-resistant sheet metal, wherein the sheathing is rigidly connected to the core wire by at least one common cold deforming process with intermediate annealing of the sheathing. The tension member of steel is used primarily as a reinforcement element or a tension member with wedge-type anchoring systems at its ends.
