Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, meticulously engineered in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Each strand is expertly infused with anti-corrosion grease and encased in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. In the rapidly growing wind power industry, our steel strands are vital for the construction of towering wind power towers, often exceeding heights of 120 meters. Concrete towers, employing advanced external prestressing techniques, utilize the unbonded prestressed steel strand's superior corrosion and fatigue resistance. This fortifies wind resistance, enhancing the structural integrity and longevity of the towers.
Our innovative product design strictly follows the distinguished JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to streamline and simplify the testing process for the sheath's tensile properties, thereby significantly enhancing its practical application and facilitating theadvancement of sheath performance. This pioneering development not only effectively standardizes sheath quality but also dramatically elevates the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand is specifically engineered for wind power concrete towers and features an exterior cable crafted for optimal performance. The sheath's thickness and grease composition can be tailored to meet specific user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's silhouette to be distinctly visible. It adheres to rigorous quality standards, ensuring the absence of air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
This product is perfectly suited for applications in Wind Power and Water Conservancy,
as well as Hydro-power Stations.
It is integral to major initiatives like The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
