Product Introduction
Discover the unparalleled excellence of our 1x7 structure unbonded prestressed steel strand, meticulously manufactured with precision in sizes of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly engineered strand is infused with premium anti-corrosion grease and enveloped in a durable sheath, making it the quintessential choice for water conservancy and hydro-power projects. In the rapidly expanding wind power industry, our steel strands play a pivotal role in constructing towering wind power towers, often exceeding heights of 120 meters. These concrete towers, utilizing advanced external prestressing techniques, capitalize on the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, thereby enhancing wind resistance and extending the longevity of the towers.
Our innovative product design complies with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing process for the sheath’s tensile properties, thereby elevating its practical usability and promoting theadvancement of sheath performance. This remarkable breakthrough not only effectively standardizes sheath quality but also significantly enhances the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, designed specifically for wind power concrete towers, features an exterior cable meticulously crafted for optimal performance. The sheath’s thickness and grease composition can be tailored to meet precise user specifications. Its surface is impeccably dense and smooth, allowing the steel strand’s silhouette to be clearly visible. It meets rigorous quality standards, ensuring the absence of air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
Applications encompass Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other major national water conservancy and hydropower projects.
