Product Introduction
Discover the outstanding engineering and superior performance of our 1x7 structure unbonded prestressed steel strand, available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Expertly designed, each strand is coated with premium anti-corrosion grease and encased in a robust sheath, making it the ideal solution for demanding water conservancy and hydro-power projects. As the renewable energy sector expands, particularly in wind power, these steel strands are increasingly utilized in the construction of monumental wind power towers, which often soar beyond 120 meters. By leveraging advanced external prestressing technology, they offer extraordinary resistance to corrosion and fatigue, significantly boosting wind resistance and prolonging the towers' structural integrity and lifespan.
Our product design adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand, marking a pivotal advancement in testing the sheath's tensile properties. This streamlined testing process enhances practical application and usability,leading to superior sheath performance. This groundbreaking innovation not only ensures the standardization of sheath quality but also remarkably enhances the safety and excellence of the entire project.
Product Characteristics
Our cutting-edge unbonded steel strand, crafted for wind power concrete towers, features an outer cable engineered for peak performance. The customization options in sheath thickness and grease composition allow for tailored solutions to specific user needs. The surface of the sheath is exceptionally dense and smooth, ensuring the strand's outline remains visible. Stringently adhering to top-quality standards, it is free from air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
Our product finds extensive applications across diverse sectors including Wind Power and Water Conservancy,
and is crucial for Hydro-power Stations projects.
It plays a pivotal role in the South-North Water Transfer Project,
River Channels, and other significant national water conservancy and hydropower projects.
