Product Introduction
Introducing our state-of-the-art 1x7 structure unbonded prestressed steel strand, meticulously available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly engineered strand is thoroughly imbued with advanced anti-corrosion grease and shrouded in an exceptionally resilient sheath, making it the perfect choice for water conservancy and hydro-power ventures. As the wind power sector experiences unprecedented growth, our steel strands have become indispensable in erecting monumental wind power towers, often reaching heights beyond 120 meters. These concrete towers, employing sophisticated external prestressing techniques, benefit immensely from the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, thereby enhancing wind resistance and significantly extending the tower's durability.
Our innovative product design strictly adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. Leveraging cutting-edge advancements, we have revolutionized the design to streamline the testing process for the sheath's tensile qualities, thereby enhancing its practical application and greatly facilitating theadvancement of sheath performance. This groundbreaking development not only effectively standardizes sheath quality but also dramatically amplifies the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically tailored for wind power concrete towers, boasts an exterior cable meticulously engineered for peak performance. Its sheath's thickness and grease formula are fully customizable to meet the precise demands of specific user needs. The surface is impeccably dense and smooth, effortlessly making the steel strand's silhouette discernible. Complying with stringent quality standards, it guarantees the complete absence of air holes, mechanical imperfections, cracks, or noticeable wrinkles.
Product Application
Our products find their applications in critical areas such as Wind Power and Water Conservancy,
as well as Hydro-power Stations,
including the prestigious South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
