Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, crafted with precision in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterfully engineered strand is enriched with anti-corrosion grease and enveloped in a durable sheath, rendering it superbly suited for water conservancy and hydro-power projects. As the wind power sector accelerates its growth, our steel strands have become indispensable for constructing towering wind power towers, frequently exceeding heights of 120 meters. These concrete towers, employing advanced external prestressing techniques, harness the remarkable corrosion and fatigue resistance of the unbonded prestressed steel strand, fortifying wind resistance and extending the tower's operational lifespan.
Our state-of-the-art product design strictly conforms to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively refined the design to streamline the testing process for the sheath's tensile properties, thereby amplifying its practical utility and facilitating theadvancement of sheath performance. This innovation not only effectively standardizes sheath quality but also significantly enhances the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, meticulously tailored for wind power concrete towers, features an exterior cable ingeniously engineered for optimal performance. The sheath's thickness and grease composition are customizable to meet specific user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's form to be distinguishable. It adheres to rigorous quality standards, ensuring no presence of air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
The domains of application include Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
