Product Introduction
Introducing the unparalleled 1x7 structure unbonded prestressed steel strand, offered in dimensions including 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Crafted with precision, this strand is enveloped in anti-corrosion grease and a robust sheath, making it an ideal solution for water conservancy and hydro-power projects. As the demand for wind power surges, our steel strands play a pivotal role in constructing imposing wind power towers, often reaching heights beyond 120 meters. These concrete marvels leverage external prestressing technology, utilizing our unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thereby enhancing wind resistance and significantly extending the towers' lifespan.
Our product design adheres to the renowned JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have redefined the design to streamline the testing of the sheath's tensile properties, thereby augmenting its practical application and simplifying the process.This advancement not only rigorously standardizes sheath quality but also markedly enhances the safety and excellence of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously designed for superior performance. The sheath's thickness and grease composition are tailored to specific user requirements, ensuring seamless integration and optimal function. Its surface is flawlessly dense and smooth, with the steel strand's outline distinctly visible. It adheres to rigorous quality standards, ensuring no air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
The areas of application include Wind Power and Water Conservancy,
along with Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other key national water conservancy and hydropower projects.
