Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, crafted with precision and available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Expertly designed, this strand is coated with high-grade anti-corrosion grease and enveloped in a resilient sheath, making it a stellar choice for water conservancy and hydro-power projects. As the demand for renewable energy surges, our steel strands have become integral in the construction of towering wind power towers, often surpassing heights of 120 meters. These concrete towers, utilizing advanced external prestressing technology, benefit greatly from our unbonded prestressed steel strand's unmatched corrosion and fatigue resistance. This not only enhances wind resistance but also extends the longevity of the towers, ensuring reliability and sustainability in high-demand environments.
Our product design is firmly rooted in the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. Innovatively, we have streamlined the design to simplify the testing procedures for the sheath's tensile properties. This enhancement significantly boosts its practical usability and paves the way for further advancements in theenhancement of sheath performance. This groundbreaking innovation not only effectively standardizes the sheath quality but also dramatically elevates the safety and quality of entire projects, offering peace of mind and superior performance.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously engineered for superior functionality. The sheath's thickness and grease composition can be tailored to meet distinct user specifications. The sheath's surface boasts an impeccably dense and smooth finish, revealing the steel strand's silhouette. It adheres to the highest quality standards, ensuring the absence of air holes, mechanical damage, cracks, or noticeable wrinkles, thus guaranteeing impeccable performance.
Product Application
Our product finds its versatile applications across various sectors, including Wind Power and Water Conservancy,
as well as at Hydro-power Stations.
Furthermore, it plays a pivotal role in The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects, making it a cornerstone of national infrastructure development.
