Product Advantages
- 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.
Applications
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.
Certifications
Our steel wire rope meets international production standards and has obtained multiple certifications such as SGS, CE, ISO, etc.
