Technical Field

[0002] Steel strand is a steel product consisting of multiple twisted steel wires, commonly used in prestressed concrete structures. It is constructed from two, three, seven, or 19 high-strength steel wires, stress-relieved to provide high strength and good relaxation properties. 1 The tensile strength of steel strand can reach over 1570 MPa. The production process consists of two main steps: monofilament production and stranding. Monofilament production involves drawing the raw steel wire to the desired diameter, followed by straightening and rust removal. Wire stranding involves twisting multiple monofilaments into the desired strand specifications. The material properties of steel strand, including high strength, good relaxation properties, and corrosion resistance, make it suitable for a variety of applications requiring high strength and stability.
