Product Introduction
Introducing our superior 1x7 structure unbonded prestressed steel strand, meticulously designed to match your exacting standards with dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is thoroughly imbued with anti-corrosion grease and encased in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry expands, our steel strands have become indispensable in constructing towering wind power structures, often exceeding heights of 120 meters. These concrete towers, utilizing advanced external prestressing techniques, capitalize on the strand's exceptional resistance to corrosion and fatigue, thereby enhancing wind resistance and significantly extending the tower's lifespan.
Our cutting-edge product design strictly adheres to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to streamline the testing process for the sheath's tensile properties, thereby optimizing its practical application and facilitating theadvancement of sheath performance. This breakthrough not only effectively standardizes sheath quality but also significantly boosts the safety and integrity of the overall project.
Product Characteristics
Our unbonded steel strand, custom-crafted for wind power concrete towers, boasts an exterior cable meticulously engineered for superior performance. The sheath’s thickness and grease formula can be tailored to perfectly meet specific user requirements. Its surface is impeccably dense and smooth, making the steel strand’s silhouette easily discernible. It strictly complies with rigorous quality standards, ensuring there are no air holes, mechanical imperfections, cracks, or visible wrinkles.
Product Application
The fields of application extend to 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 initiatives.
