Product Introduction
Introducing our top-tier 1x7 structure unbonded prestressed steel strand, available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterfully engineered strand is fortified with anti-corrosion grease and enveloped in a robust sheath, making it ideal for major water conservancy and hydro-power projects. In the rapidly expanding wind power industry, our steel strands are pivotal in constructing towering wind power towers, often soaring over 120 meters. These concrete towers, utilizing external prestressing methods, capitalize on the unbonded prestressed steel strand's exceptional resistance to corrosion and fatigue, thereby enhancing wind resistance and significantly extending the tower's lifespan.
Our state-of-the-art product design meticulously adheres to the distinguished JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively refined the design to streamline the testing process for the sheath's tensile properties, thereby elevating its practical use and facilitating theadvancement of sheath performance. This revolutionary enhancement not only effectively standardizes sheath quality but also dramatically elevates the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, exquisitely crafted for wind power concrete towers, features a meticulously engineered exterior cable for optimal performance. The sheath's thickness and grease composition can be tailored to meet specific user requirements. Its surface boasts an impeccably dense and smooth finish, making the steel strand's outline clearly visible. It adheres to rigorous quality standards, ensuring there are no air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
The applications span across 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 endeavors.
