Product Introduction
Introducing our extraordinary 1x7 structure unbonded prestressed steel strand, available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This precision-engineered strand, coated meticulously with anti-corrosion grease and ensconced in a robust, durable sheath, stands as the ideal choice for ambitious water conservancy and hydro-power projects. In response to the escalating demand for wind power advancements, our steel strands are increasingly pivotal in constructing majestic wind power towers, soaring beyond heights of 120 meters. These cutting-edge concrete towers, leveraging external prestressing technology, harness the unbonded prestressed steel strand’s unparalleled corrosion and fatigue resistance. This innovation not only fortifies wind resistance but also significantly amplifies the lifespan of the towers.
Our product design is rooted in the acclaimed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered advancements in the design to streamline the testing process for the sheath's tensile properties, thereby enhancing its practical usability and facilitating theimprovement of sheath performance. This groundbreaking innovation not only effectively standardizes sheath quality but also significantly elevates the safety and overall quality of projects, marking a substantial progression in construction excellence.
Product Characteristics
Our unbonded steel strand, specifically tailored for wind power concrete towers, features an outer cable designed for pinnacle performance. The sheath's thickness and grease composition are customizable, allowing precise adaptation to specific user requirements. Its surface is impeccably dense and smooth, with the steel strand's outline discernibly visible. It adheres to stringent quality benchmarks, ensuring the absence of air holes, mechanical damage, cracks, or notable wrinkles.
Product Application
The application domains span Wind Power and Water Conservancy,
in addition to Hydro-power Stations.
This includes the South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
