Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This meticulously engineered strand is coated with high-grade anti-corrosion grease and ensconced in a robust, protective sheath, positioning it as the quintessential choice for water conservancy and hydro-power projects. In response to the surging demand for renewable energy sources, particularly wind power, our steel strands are increasingly instrumental in the construction of soaring wind power towers, often reaching impressive heights exceeding 120 meters. Leveraging external prestressing technology, the concrete towers benefit from the unbonded prestressed steel strand's unparalleled corrosion and fatigue resistance, significantly boosting wind resistance and prolonging tower longevity.
Our product design is anchored on the prestigious 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 theelevation of sheath performance. This innovation not only standardizes the sheath quality with precision but also significantly elevates the safety and quality of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously engineered for optimal performance. The sheath's thickness and grease composition are customizable, tailored to meet specific user requirements. Sporting a surface that's impeccably dense and flawlessly smooth, the steel strand's outline is discernible, meeting the most rigorous quality standards. This ensures an absence of air holes, mechanical damage, cracks, or conspicuous wrinkles.
Product Application
Our unbonded PC strand is expertly applied in domains such as Wind Power and Water Conservancy,
as well as in the construction of Hydro-power Stations.
It also plays a critical role in the South-North Water Transfer Project,
serving River Channels and other nationally prioritized water conservancy and hydropower initiatives.
