Product Introduction
Behold the pinnacle of engineering excellence with our 1x7 structure unbonded prestressed steel strand, a marvel in precision and durability. Available in exact sizes of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, each strand is meticulously infused with anti-corrosion grease and enveloped in a robust sheath. It stands as the quintessential choice for critical water conservancy and hydro-power projects. As the wind energy industry reaches new heights, our steel strands are pivotal in constructing towering wind power towers, often exceeding towering heights of 120 meters. These concrete towers, buttressed by innovative external prestressing techniques, utilize the unparalleled resistance to corrosion and fatigue offered by our unbonded prestressed steel strands, thereby enhancing wind resistance and extending the longevity of these majestic structures.
Our cutting-edge product design strictly adheres to the renowned JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have ingeniously redefined the design to streamline the testing process for the sheath's tensile properties, thereby amplifying its real-world applicability and seamlessly facilitating theprogression of sheath performance. This remarkable advancement not only establishes a new benchmark for sheath quality but also significantly elevates the safety and structural integrity of the entire project.
Product Characteristics
Introducing our premium unbonded steel strand, specifically crafted for wind power concrete towers. It boasts an exterior cable designed for unrivaled performance. The sheath's thickness and grease composition can be customized to meet specific user preferences. With a surface that is impeccably dense and smooth, the steel strand's silhouette remains clearly visible. It adheres to the most rigorous quality standards, ensuring it is free from air voids, mechanical flaws, cracks, or conspicuous wrinkles.
Product Application
Our product finds its application in diverse sectors including Wind Power and Water Conservancy,
as well as Hydro-power Stations.
It plays a fundamental role in the South-North Water Transfer Project,
River Channels, and other major national water conservancy and hydropower projects of immense significance.
