Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand, meticulously engineered in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterpiece is infused with advanced anti-corrosion grease and enveloped in a robust sheath, making it the quintessential choice for water conservancy and hydro-power projects. As the wind power industry experiences unprecedented growth, our steel strands are vital in constructing towering wind power towers, often exceeding 120 meters. These concrete towers, utilizing innovative external prestressing techniques, harness the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, enhancing wind resistance and significantly extending the tower's lifespan.
Our state-of-the-art product design conforms to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to simplify the testing process for the sheath's tensile properties, thus elevating its practical utility and advancing theperformance of the sheath. This milestone achievement not only standardizes sheath quality effectively but also substantially enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically engineered for wind power concrete towers, features an external cable finely crafted for optimal performance. The sheath's thickness and grease formula are customizable to meet precise user specifications. Its surface is impeccably dense and smooth, revealing the steel strand's silhouette. It adheres to rigorous quality standards, ensuring no air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
The applications extend to Wind Power and Water Conservancy,
in addition to Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
