Product Details

●Production Standards and Processes: Products are manufactured strictly according to the GB/T 5224 national standard, using high-quality, high-strength carbon steel wire as raw material. They are produced through multiple professional processes including precision stranding, stabilization tempering, and stress relief, resulting in excellent craftsmanship and high product stability.

●Mainstream Specifications and Categories: Commonly used structures include classic specifications such as 1×7 and 1×19. A complete range of products is available, covering smooth prestressed steel strands, galvanized steel strands, and low-relaxation steel strands, adaptable to various engineering conditions.

●Appearance and Structural Advantages: The overall stranding is tight, the twist pitch is uniform, and the straightness is excellent. The finished product is free of loose wires, broken wires, and warping defects, with a regular structure that lays the foundation for stable stress distribution.

●Core Mechanical Properties: After low-temperature stabilization treatment, it possesses extremely low relaxation rate, fatigue resistance, and high elongation. Conventional tensile strength can reach 1860MPa and 1960MPa. It exhibits uniform stress distribution, extremely high load-bearing capacity, and is not easily deformed or broken under long-term heavy loads.

●Corrosion and Weather Resistance: Supports various surface treatments such as smooth finish, hot-dip galvanizing, and epoxy spraying, effectively resisting rust and aging. It is resistant to moisture, high and low temperatures, and suitable for complex engineering environments including outdoor, deep burial, high load, and mild corrosion applications.

●Construction and Usage Advantages: Excellent anchoring performance and toughness, meeting the demands of high-intensity operations such as tensioning, anchoring, load-bearing, and pulling. It boasts strong construction adaptability, high stability, and long service life, making it a core load-bearing material for various prestressed key projects.

Application scenarios

●Bridge and Transportation Infrastructure Engineering: Primarily used for the construction of main cables and suspenders of cable-stayed bridges and suspension bridges, as well as prestressed beams and slabs for bridges. Also suitable for highway and railway subgrade reinforcement, guardrail tensioning, tunnel lining, and slope anchoring, effectively improving the structural bearing capacity, seismic resistance, and crack resistance.

●Building Construction: Widely used in the reinforcement of prestressed floor slabs, roof beams, pile foundations, and underground garage roof slabs for high-rise buildings and large-span factory buildings. It can also be used for tensioning construction of prefabricated concrete structures, effectively reducing component cross-sections and building weight, significantly saving project costs.

●Hydraulic and Geotechnical Engineering: Applicable to reservoir dam reinforcement, dam anchoring, foundation pit slope protection, mountain slope protection, and tunnel surrounding rock anchoring, providing strong stability and effectively preventing soil and rock collapse, ensuring project safety.

●In the power and telecommunications sector: Galvanized steel strand is specifically designed for use as load-bearing guy wires for high-voltage transmission towers, overhead ground wires, communication tower mast guy wires, and fiber optic cable reinforcing cores. It boasts strong tensile strength, resistance to outdoor corrosion, and is suitable for long-term outdoor applications in power and telecommunications.

●In other industrial applications: It can be used in heavy-duty operations such as mine tunnel support, large equipment lifting and traction, and steel structure traction and fixing. It offers a high safety factor and strong durability, meeting the needs of various high-load, long-term industrial engineering projects.
