Product Introduction
Introducing our outstanding 1x7 structure unbonded prestressed steel strand, available in the dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This intricately engineered strand is fortified with anti-corrosion grease and encased in a robust sheath, making it the ultimate solution for water conservancy and hydro-power projects. With the surge in demand for wind power initiatives, our steel strands are increasingly employed in the construction of towering wind power structures, often reaching majestic heights beyond 120 meters. These concrete towers, utilizing advanced external prestressing technology, leverage the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance—thereby enhancing wind resistance and significantly prolonging the lifespan of the towers.
Our product design is firmly rooted in the renowned JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered a revolutionary design that streamlines the testing process for the sheath's tensile properties, thereby boosting its practical usability and facilitating theadvancement of sheath performance. This innovation not only standardizes sheath quality effectively but also remarkably 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 crafted for optimal performance. The sheath's thickness and grease composition can be tailored to meet specific user requirements. The sheath's surface is flawlessly dense and smooth, allowing the steel strand's outline to be discernible. It adheres to rigorous quality standards, ensuring the absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
The fields of application extend to Wind Power, and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
