PC Strand Wire (Prestressed Concrete Strand) – twisted from multiple high-strength steel wires, serving as core prestressing material for concrete structures. Stable stress performance, low relaxation rate, high load capacity, uniform mechanical properties across coils. Enhances tensile strength, stability and service life of concrete members, reduces cracking and deformation. Ideal for large-scale, high-load, long-span civil and infrastructure projects.

The PC strand wire adopts the mainstream and mature 7-wire strand structure with stable structural coordination. It covers widely applicable nominal diameters including 9.53mm, 12.7mm, 15.2mm and 17.8mm to adapt to different engineering load demands. Multiple tensile strength grades are available, including 1570MPa, 1720MPa, 1860MPa and 1960MPa, covering conventional and high-strength engineering standards. The standard coil length is 2000 meters, which facilitates unified construction arrangement, transportation and on-site cutting, effectively improving construction efficiency.

The product adopts premium high-carbon high-strength steel raw materials to ensure superior structural performance. It is manufactured from high-quality steel rods with a strict carbon content ranging from 0.70% to 0.85%. This high-carbon steel formula provides excellent hardness, tensile toughness and structural uniformity after professional heat treatment, completely meeting the ultra-high strength and low-relaxation technical requirements of prestressed engineering, and laying a solid foundation for long-term stable structural stress bearing.

With outstanding low-relaxation and high-strength performance, the PC strand wire is widely applied in key heavy-duty infrastructure projects. Its main application scenarios include bridge prestressed beams, high-speed railway sleepers, large-span building floor slabs, urban viaducts, hydraulic dams and nuclear power engineering. It is universally used in all prestressed concrete structures that require high stability and long-term safety.

The product adopts a precise and standardized professional production process: firstly, complete multi-pass high carbon steel rod wire drawing to refine steel texture; secondly, conduct online continuous quenching and tempering heat treatment to greatly enhance overall tensile strength and toughness; thirdly, finish precise multi-wire twisting to form integrated strand structure; fourthly, carry out uniform surface oil coating for effective anti-rust protection; finally, complete professional relaxation performance testing, qualified product coiling and standardized packaging.

During transportation and construction, avoid violent collision, extrusion and sharp scratching to prevent strand deformation and surface damage that may affect stress performance. Strictly follow engineering standards for tensioning construction to avoid over-tensioning or uneven stress distribution. Store the products in dry, waterproof and well-ventilated warehouses, and keep away from humid and corrosive environments to prevent rusting. Professional equipment and certified construction personnel are required for installation to ensure engineering safety.

Different from all PVC and PE coated protective wires used for fencing and binding, PC strand wire is a pure high-strength steel structural material with far higher tensile strength and structural bearing capacity, designed for building stress bearing rather than surface protection. Compared with high-carbon PE coated wire and high-tensile PVC wire, it features ultra-low relaxation performance and more stable long-term stress resistance, making it exclusive for high-standard prestressed concrete engineering, while other coated wires are only suitable for conventional protection and temporary fixing scenarios.
