Product Introduction

Prestressed steel strand is a steel product made by twisting multiple high-strength steel wires. After stress relief treatment, it has extremely high tensile strength and flexibility. It is mainly used for prestressed tensioning of concrete structures to enhance the load-bearing capacity, crack resistance, and durability of the structure.

Product Advantages

  • High strength: The tensile strength is 3-5 times that of ordinary steel Low relaxation: minimal stress loss during long-term use, ensuring structural stability Corrosion resistance: The corrosion resistance can be improved through processes such as galvanizing and epoxy coating Easy to construct: Good flexibility, convenient for transportation and on-site tensioning operations

Applications

Bridge engineering: box girder and cable-stayed structures for large-span bridges Construction engineering: high-rise building floor slabs, prestressed concrete beams Transportation Engineering: Highway Slope Anchoring, Railway Sleepers Special engineering: nuclear power plant containment, water conservancy and hydropower dams

Certifications

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