Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand, meticulously crafted in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This impeccable strand is infused with top-grade anti-corrosion grease and encased in a robust sheath, making it an ideal choice for water conservancy and hydro-power projects. As the wind power industry rapidly expands, our steel strands are indispensable in constructing towering wind power towers, often reaching majestic heights exceeding 120 meters. The concrete towers, utilizing state-of-the-art external prestressing techniques, benefit from the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thus enhancing wind resistance and significantly extending the tower's lifespan.
Our groundbreaking product design strictly adheres to 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 optimizing its functional application and facilitating theenhancement of sheath performance. This innovative advancement not only effectively standardizes sheath quality but also substantially enhances 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 meticulously designed for unparalleled performance. The sheath's thickness and grease formulation are customizable to meet precise user specifications. Its surface is impeccably dense and smooth, making the steel strand's outline unmistakably visible. It adheres to stringent quality standards, guaranteeing the absence of air holes, mechanical defects, cracks, or pronounced wrinkles.
Product Application
The scope of application encompasses Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and a range of other nationally significant water conservancy and hydropower projects.
