Product Introduction
Introducing our exceptional 1x7 unbonded prestressed steel strand, meticulously available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Each strand is expertly crafted with anti-corrosion grease and enveloped in a robust sheath, making it the prime choice for water conservancy and hydro-power projects. As the wind power industry flourishes, these steel strands have become pivotal in constructing towering wind power structures, exceeding heights of 120 meters. The concrete towers employ advanced external prestressing techniques, harnessing the strand's outstanding resistance to corrosion and fatigue. This fortifies wind resistance and significantly enhances the longevity of the towers.
Our innovative product design is in full compliance with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to optimize the testing processes for the sheath's tensile properties, thereby amplifying its practical application and facilitating theenhancement of sheath performance. This groundbreaking advancement not only standardizes sheath quality effectively but also substantially elevates the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically engineered for wind power concrete towers, features an exterior cable precision-crafted for optimal performance. The sheath's thickness and grease composition are fully customizable to meet precise user specifications. Its surface is impeccably smooth and dense, making the steel strand's silhouette clearly visible. It meets rigorous quality standards, ensuring no air pockets, mechanical flaws, cracks, or visible wrinkles.
Product Application
Our product finds applications in the Wind Power industry and Water Conservancy,
as well as Hydro-power Stations.
Notable projects include the South-North Water Transfer Project,
and River Channels, among other nationally significant water conservancy and hydropower projects.
