Low Relaxation PC Strand 9.53mm 15.2mm 12.7mm ASTM A416 Galvanized PC Strand 1*7

Prestressed steel strand is a metal component made up of multiple high-strength steel wires twisted together. After stress relief treatment, it has high tensile strength, low relaxation, and good flexibility. It is the core load-bearing material of prestressed concrete structures.

It generates prestress through pre-tensioning, effectively offsetting the tensile stress of concrete, greatly improving the bearing capacity and durability of bridges, high-speed railways, nuclear power plants, high-rise buildings and other engineering projects. It has the characteristics of convenient construction and high cost-effectiveness, and is an indispensable key material in modern large-scale civil engineering.

• Ultra high strength, precise force control: Made of high carbon steel wire rod through cold drawing, twisting, and stabilization treatment, with a tensile strength of over 1860MPa, far exceeding ordinary steel; Low relaxation performance ensures that stress loss is less than 2% during long-term use, providing long-lasting and precise prestressing support for concrete structures.
• Flexible and adaptable, efficient construction: The multi wire twisted structure combines rigidity and flexibility, and can adapt to complex curve reinforcement requirements; The length of a single piece can reach up to kilometers, reducing the number of on-site joints, significantly shortening the construction period, and lowering labor costs.
• Corrosion resistant and durable, with a long lifespan: The surface can be galvanized, aluminum zinc coated, or coated with epoxy resin, which can effectively resist corrosion in harsh environments such as high humidity and salt alkali; Strong adhesion with concrete, when used in conjunction with anti-corrosion sleeves, the structural lifespan can reach over a hundred years.
• Diverse specifications and flexible customization: Different structures such as 7-wire and 19 wire, as well as various diameters such as 15.2mm and 17.8mm, can be customized according to engineering needs. Special models such as low relaxation, ultra-high strength, and anti-corrosion can also be provided to adapt to various scenarios from bridges to nuclear power.

As the core load-bearing material for bridges, high-speed railways, and highways, it is used for box girders and stay cables of large-span bridges, ballastless track beds of high-speed railway tracks, and slope reinforcement of highways. By using prestress to counteract structural self weight and dynamic loads, it improves engineering stability and service life.
