Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, meticulously crafted to precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This advanced strand is infused with anti-corrosion grease and enveloped in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands have become pivotal in constructing towering wind power structures, some exceeding 120 meters. Through the innovative use of external prestressing techniques, these concrete towers capitalize on the unbonded prestressed steel strand's superior corrosion and fatigue resistance, thereby enhancing wind resistance and extending the tower's lifespan.
Our state-of-the-art product design 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, consequently boosting its practical application and driving theadvancement of sheath performance. This innovation not only effectively standardizes sheath quality but also greatly enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand is purpose-built for wind power concrete towers, featuring an exterior cable designed with precision for maximum performance. The sheath's thickness and grease formulation can be customized to meet specific user needs. Its surface is impeccably dense and smooth, allowing the steel strand's profile to stand out. It meets stringent quality standards, ensuring no air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
The application range includes Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other major national water conservancy and hydropower projects.
