Product Introduction
Discover our exceptional 1x7 structure unbonded prestressed steel strand, meticulously crafted for precision with available dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Infused with anti-corrosion grease and enveloped in a robust sheath, this strand is the epitome of reliability for water conservancy and hydro-power projects. As the wind power industry thrives, our steel strands are pivotal in constructing towering wind power installations exceeding 120 meters. These concrete towers utilize advanced external prestressing techniques, harnessing the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, thus enhancing wind tolerance and significantly extending the lifespan of the structures.
Our innovative product design rigorously complies with the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. This design revolutionizes the evaluation of the sheath's tensile properties, elevating its application efficacy and streamlining theenhancement of sheath performance. This pioneering development not only standardizes sheath quality with precision but also elevates the safety and robustness of the entire project.
Product Characteristics
Our unbonded steel strand, engineered for wind power concrete towers, boasts an outer cable crafted for optimal efficiency. The customizable sheath thickness and grease formula are tailored to meet specific user demands. The surface is impeccably dense and smooth, ensuring the steel strand's contours remain clearly visible. It adheres to rigorous quality criteria, guaranteeing no air holes, mechanical defects, cracks, or discernible wrinkles.
Product Application
Our product finds its application in the expansive domains of Wind Power and Water Conservancy,
as well as in Hydro-power Stations,
contributing to crucial projects like the South-North Water Transfer Project,
and River Channels, along with other vital national water conservancy and hydropower developments.
