Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strands, available in precision dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. These expertly crafted strands are infused with anti-corrosion grease and enveloped in a robust sheath, making them an exemplary choice for water conservancy and hydro-power projects. With the wind power industry flourishing, our steel strands are pivotal in constructing towering wind power towers that often exceed heights of 120 meters. The concrete towers, utilizing external prestressing techniques, benefit from the unbonded prestressed steel strand's superior corrosion and fatigue resistance, enhancing wind resistance and extending the tower's lifespan.
Our state-of-the-art product design aligns with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strands. We have innovatively redesigned the structure to streamline the testing process for the sheath's tensile characteristics, thereby elevating its practical application and propelling theadvancement of sheath performance. This groundbreaking innovation not only effectively standardizes sheath quality but also significantly enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, expertly tailored for wind power concrete towers, boasts an exterior cable meticulously engineered for optimal performance. The sheath's thickness and grease formula are customizable to meet specific user requirements. Its surface is impeccably dense and smooth, making the steel strand's profile easily visible. It adheres to strict quality standards, guaranteeing no air holes, mechanical defects, cracks, or noticeable wrinkles.
Product Application
Our product finds application in sectors such as Wind Power and Water Conservancy,
as well as in Hydro-power Stations.
Notably, the South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
