Product Description
15.2mm Prestressed Steel Strand Bridge Concrete Strand 17.8mm
Mine Prestressed Anchor Cable Strand
Product Introduction
Prestressed steel strand is a prestressed steel made by twisting multiple high-strength steel wires.
After stress relief and stabilization treatment, it has the core characteristics of high strength and
low relaxation. The mainstream specification is 7 φ 5 (7 strands of 5mm diameter steel wire twisted
together), with a tensile strength of up to 1860MPa, far exceeding ordinary steel. The product is
strictly produced in accordance with the GB/T 5224-2014 standard, and the surface can be galvanized,
coated with epoxy resin, or coated with grease anti-corrosion layer according to needs, suitable for
different service environments.

Product Advantages
Ultra high strength: The unit weight bearing capacity is 4-6 times that of ordinary steel, significantly
reducing the structural weight and saving material costs
Low relaxation performance: Under long-term stress, the stress loss is ≤ 2.5%, ensuring the long-term
stability of the structure
Corrosion resistance: The special coating treatment increases the service life of the product by more than
30% in harsh environments such as the ocean and salt alkali
Convenient construction: Good flexibility, can be cut and bundled as needed, suitable for complex structural
construction needs
Product Application
Widely used in engineering fields such as highway and railway bridges, high-rise building foundation
anchor rods, water conservancy and hydropower dams, nuclear power facilities, slope reinforcement,
etc. In the construction of large-span bridges, it can effectively enhance the structural crossing capacity;
In high-rise buildings, achieving column free layout in large spaces through prestressed floor slab design;
In hydraulic engineering, it is used to reinforce dam bodies and resist water pressure deformation.
At present, it has become the core load-bearing component in modern prestressed concrete structural systems.
Product Certificate
Our steel wire rope meets international production standards and has obtained multiple
certifications such as SGS, CE, ISO, etc
