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
