Prestressed steel strand is a multi-strand steel strand composed of 2, 3, 7 or 19 high-strength steel wires, and has undergone stress relief treatment (stabilization treatment), suitable for prestressed concrete or similar purposes. After surface treatment, the high-carbon steel wire rod is cold drawn into steel wire, and then a certain number of steel wires are twisted into a strand according to the structure of the steel strand, and then formed by a stable process of eliminating stress. The main characteristics of prestressed steel strands are high strength, good relaxation performance, and relatively straight when unfolded. Common tensile strength grades are 1720, 1770, 1860 MPa, this steel has a higher yield strength.

Our Strand meets customers' requirements as well as GB/T5224, ASTM416, BS5896, En10138-3, JIS G3536.
