As the core consumable of high-strength prestressed concrete structures, our prestressed steel strands are manufactured from high-quality high carbon steel raw materials. The products are twisted and stabilized by multiple wires, covering multiple series including 1×7 standard type, galvanized, and epoxy coating variants.
With a strength grade of 1860MPa, these strands far exceed ordinary steel by 3-4 times, providing exceptional performance for demanding applications.
