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 robust sheath, making it the premier choice for water conservancy and hydro-power projects. In response to the ever-growing wind power sector, our steel strands are increasingly in demand for constructing towering wind power towers, often surpassing heights of 120 meters. These concrete towers, utilizing state-of-the-art external prestressing technology, benefit immensely from the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thereby enhancing wind resistance and significantly extending the lifespan of the towers.
Our product design is crafted in strict adherence to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered a transformative design that simplifies the testing process for the sheath's tensile properties, thereby enhancing its practical usability and facilitating theenhancement of sheath performance. This breakthrough not only effectively standardizes sheath quality but also significantly elevates the safety and overall quality of projects, ensuring excellence at every stage.
Product Characteristics
Our unbonded steel strand, designed specifically for wind power concrete towers, features an outer cable engineered for peak performance. The sheath's thickness and grease composition are customizable, tailored to meet specific user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's outline to be discernible. Adhering to stringent quality standards, it ensures there are no air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
The scope of application spans Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and additional nationally prioritized water conservancy and hydropower projects.
