Product Introduction
Introducing our top-tier 1x7 structure unbonded prestressed steel strand, precision-engineered in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly designed strand is enriched with anti-corrosion grease and enveloped in a durable sheath, making it perfect for robust water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands play a vital role in constructing towering wind power towers, often exceeding 120 meters. These concrete towers, employing external prestressing techniques, take advantage of the unbonded prestressed steel strand's superior corrosion and fatigue resistance, thereby enhancing wind resistance and extending the tower's longevity.
Our state-of-the-art product design conforms to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to optimize the testing process for the sheath's tensile properties, thereby elevating its practical application and facilitating theadvancement of sheath performance. This 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, crafted for wind power concrete towers, boasts an exterior cable meticulously engineered for optimum performance. The sheath's thickness and grease formulation are adaptable to cater to specific user requirements. Its surface is impeccably dense and smooth, highlighting the steel strand's outline. It meets rigorous quality standards, ensuring no air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
The domains of application encompass Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
