Prestressed steel strand is a steel product made by twisting multiple high-strength steel wires. By applying prestress, it can greatly improve the tensile performance of concrete structures and is the core load-bearing material of prestressed concrete engineering.
Mainstream specifications: Made by twisting 7 steel wires with a diameter of 5mm~7mm, the finished product diameter is usually 12.7mm, 15.2mm, 17.8mm, 21.6mm, etc.
Mechanical properties: The tensile strength can reach 1860MPa, which is more than 6 times that of ordinary steel.
