Product Introduction
Introducing our remarkable 1x7 structure unbonded prestressed steel strand, available in diverse dimensions: 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is infused with anti-corrosion grease and encased in a robust sheath, emerging as the ideal selection for water conservancy and hydro-power projects. As the demand for wind power initiatives soars, our steel strands are increasingly employed in the construction of majestic wind power towers, often surpassing heights of 120 meters. These concrete towers, fortified with external prestressing technology, leverage the unbonded prestressed steel strand's extraordinary corrosion and fatigue resistance, thereby amplifying wind resistance and extending the lifespan of the towers.
Our product design adheres to the acclaimed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have reimagined the design to simplify the sheath's tensile property testing process, thereby enhancing its practical applicability, and enabling theimprovement of sheath performance. This pioneering innovation not only standardizes sheath quality with precision but also significantly elevates the safety and quality of the entire project.
Product Characteristics
Engineered specifically for wind power concrete towers, our unbonded steel strand features an outer cable designed for superior performance. The sheath's thickness and grease formulation can be tailored to meet precise user specifications. Its surface is flawlessly dense and smooth, allowing the steel strand's contour to be discernible. It complies with rigorous quality standards, ensuring an absence of air holes, mechanical damage, cracks, or prominent wrinkles.
Product Application
Our product finds applications in diverse domains such as Wind Power and Water Conservancy,
as well as Hydro-power Stations.
It is instrumental in the South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
