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 anti-corrosion grease and enveloped in a durable sheath, making it the perfect choice for water conservancy and hydro-power projects. With the growing demand for wind power initiatives, our steel strands are increasingly utilized in constructing towering wind power towers, often exceeding heights of 120 meters. The concrete towers, utilizing external prestressing technology, capitalize on the unbonded prestressed steel strand's remarkable corrosion and fatigue resistance-thereby enhancing wind resistance and extending the lifespan of the towers.
Our product design is anchored on the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing process for the sheath's tensile properties, thus augmenting its practical usability, and facilitating the enhancement of sheath performance. This innovation not only effectively standardizes the sheath quality but also significantly elevates the safety and quality of the overall project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers boasts an outer cable specifically designed for optimal performance. The sheath's thickness and grease composition are customizable to meet specific user requirements. The sheath's surface is impeccably dense and smooth, allowing the steel strand's outline to be visible. It meets stringent quality standards, ensuring there are no air holes, mechanical damage, cracks, or conspicuous wrinkles.
Product Application
The domains of application encompass Wind Power, and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
