Product Introduction
Introducing our outstanding 1x7 structure unbonded prestressed steel strand, masterfully designed with dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is enveloped in a durable sheath and coated with advanced anti-corrosion grease, making it an optimal choice for water conservancy and hydro-power projects. As the demand for wind power initiatives surges, our steel strands are becoming integral to the construction of impressive wind power towers, often reaching majestic heights beyond 120 meters. These concrete towers, employing cutting-edge external prestressing technology, harness the unbonded steel strand's superior corrosion and fatigue resistance, thereby significantly enhancing wind resistance and prolonging the towers' longevity.
Our innovative product design is rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to streamline the testing process for the sheath's tensile properties, thereby enhancing its practical usability and facilitating theenhancement of sheath performance. This cutting-edge innovation not only effectively standardizes sheath quality but also remarkably elevates the safety and overall quality of the project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers is distinguished by an outer cable engineered for peak performance. The sheath's thickness and grease composition are tailored to meet precise user specifications. The sheath's surface is impeccably dense and smooth, revealing the steel strand's outline. It adheres to rigorous quality standards, ensuring the absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
Our product finds versatile applications in Wind Power and Water Conservancy,
in addition to Hydro-power Stations.
It is also employed in projects like the South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
