Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand, crafted with precision in sizes of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This high-performance strand is fortified with anti-corrosion grease and encased in a robust sheath, making it the optimal choice for water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands have become essential for constructing towering wind power installations, often exceeding 120 meters. These concrete towers, utilizing advanced external prestressing techniques, benefit from the strand's outstanding corrosion and fatigue resistance, thereby enhancing wind resilience and extending their lifespan.
Our innovative 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 of the sheath's tensile properties, thus boosting its practical application and contributing to theenhancement of sheath performance. This innovation not only standardizes sheath quality effectively but also significantly elevates the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, precisely engineered for wind power concrete towers, boasts an outer cable meticulously crafted for optimal performance. The sheath's thickness and grease composition can be customized to meet specific user requirements. Its surface is impeccably dense and smooth, ensuring the steel strand's silhouette is distinct. It meets rigorous quality standards, guaranteeing no air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
Our product is ideally suited for Wind Power and Water Conservancy,
including Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
