The utility model relates to a prestress concrete-use steel stranded wire which is characterized in that the prestress concrete-used steel stranded wire made by the twisting of 3-18 strands of wires, and corrosion-resistant coating (1) exists outside the prestress concrete-used steel stranded wire twisted into a whole and/or the clearances among various stands of wires. Compared with prior steel stranded wires, the prestress concrete-used steel stranded wire has remarkable anti-fatigue performance and anti-corrosion performance, has good stability and can be well held (agglutinated) with concrete or grout; the prestress concrete-used steel stranded wire has predictable great economic and social value.
