Prestressed concrete steel strand, also known as 1— 7 low-relaxation prestressed concrete strand, is twisted steel cable composed of 7 high-strength steel wires, which has been through the stress relief treatment (stabilized). Steel embedded in prestressed concrete structure has been pre-stretched before load been applied on, applying a prestressing force on the concrete to offset or reduce the tensile stress generated by load, thereby enhancing the crack resistance and stiffness of the components, reducing the width of cracks, as well as using high-strength steel and concrete effectively to save steel material and reduce the weight.
Features:
High-strength, low-relaxation, supply in coil, large-length, low-consumption, strong bond with concrete, convenient construction.
Tensile strength grades are of 1860MPa (common) and 1720, 1960, 2000 Mpa.
