Product Introduction
Introducing our extraordinary 1x7 structure unbonded prestressed steel strand, crafted with precision and available in diverse dimensions: 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterfully engineered product is not only coated in anti-corrosion grease but also encased in a robust sheath, making it an impeccable choice for water conservancy and hydro-power projects. As the demand for renewable wind energy initiatives surges, our steel strands are becoming integral in the construction of towering wind power towers, reaching impressive heights beyond 120 meters. The concrete towers, fortified with external prestressing technology, leverage the unparalleled corrosion and fatigue resistance of our unbonded prestressed steel strand, thereby significantly boosting wind resistance and prolonging the durability and lifespan of these monumental structures.
Our product design is rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have ingeniously transformed the design to streamline the testing process for the sheath's tensile properties, thereby enhancing its practical adaptability and facilitating theelevation of sheath performance. This groundbreaking innovation not only standardizes the sheath quality effectively but also substantially improves the safety and quality of the entire project.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, showcases an exterior cable meticulously designed for superior performance. The thickness of the sheath and the grease composition can be precisely customized to cater to specific user requirements. The sheath's surface is flawlessly dense and smooth, allowing the silhouette of the steel strand to be discernible. It adheres to strict quality standards, ensuring the absence of air holes, mechanical damage, cracks, or prominent wrinkles.
Product Application
The realms of application include 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 ventures.
