Product Introduction
Introducing our outstanding 1x7 structure unbonded prestressed steel strand, brilliantly crafted in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly engineered strand is shielded with anti-corrosion grease and enveloped in a highly durable sheath—an ideal solution for water conservancy and hydro-power projects. With the surge in wind power initiatives, our steel strands are progressively employed in constructing magnificent wind power towers, often soaring beyond 120 meters. These concrete towers, using external prestressing technology, take full advantage of the unbonded prestressed steel strand's superior corrosion and fatigue resistance, thereby significantly boosting wind resistance and extending the towers' lifespan.
Our product design adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively transformed the design to streamline the sheath's tensile property testing, thereby enhancing its practical usability and making theimprovement of sheath performance more accessible. This breakthrough not only effectively standardizes sheath quality but also substantially elevates the safety and quality of the overall project.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an outer cable meticulously designed for peak performance. The sheath's thickness and grease composition can be customized to meet precise user specifications. Its surface is flawlessly dense and smooth, allowing the steel strand's profile to be discernible while adhering to rigorous quality standards, ensuring no air holes, mechanical damage, cracks, or visible wrinkles.
Product Application
Our product applications span Wind Power and Water Conservancy,
along with Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
