Prestressed steel strand is a metal wire made up of multiple high-strength steel wires twisted together. By applying tensile stress in advance before the construction of concrete structures, it offsets the compressive stress generated during the use of the structure, thereby improving the crack resistance, stiffness, and bearing capacity of the components. It is the core load-bearing material of prestressed concrete structures, widely used in engineering fields such as bridges, buildings, and water conservancy.
