Product Introduction
Introducing our premium-quality 1x7 structure unbonded prestressed steel strand, available in versatile dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand features a protective layer of anti-corrosion grease and is encased in a robust sheath, making it an ideal solution for water conservancy and hydro-power projects. As the demand for renewable energy surges, our versatile steel strands have become instrumental in the construction of monumental wind power towers, often surpassing towering heights of 120 meters. The concrete towers, which employ advanced external prestressing technology, benefit from the unbonded prestressed steel strand's outstanding resistance to corrosion and fatigue, thereby significantly boosting wind resistance and prolonging the tower's operational lifespan.
Our innovative product design adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've reimagined the design to streamline the testing process for the sheath's tensile properties, thereby enhancing its practical usability and facilitating theadvancement of sheath performance. This breakthrough not only ensures the standardization of sheath quality but also markedly improves the safety and overall quality of your projects.
Product Characteristics
Our cutting-edge unbonded steel strand, tailored for wind power concrete towers, features an outer cable engineered for superior performance. The customization of both the sheath's thickness and grease composition ensures precise alignment with specific user requirements. The sheath's surface is meticulously crafted to be dense and smooth, allowing the steel strand's silhouette to remain visible. Compliant with rigorous quality standards, it guarantees the absence of air holes, mechanical damage, cracks, or unsightly wrinkles.
Product Application
Our product finds its applications in the fields of Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower ventures.
