Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand! Available in precisely engineered dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, each strand is meticulously crafted with anti-corrosion grease and enveloped in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry continues to surge, our steel strands have become essential in constructing towering wind power installations, often exceeding 120 meters in height. These concrete towers employ advanced external prestressing techniques to harness the unbonded prestressed steel strand's unparalleled resistance to corrosion and fatigue. This not only enhances wind resistance but also extends the longevity of these formidable structures.
Our state-of-the-art product design conforms to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to optimize the testing process for the sheath's tensile properties, thus improving its practical application while facilitating theenhancement of sheath performance. This innovation effectively sets a benchmark for sheath quality, significantly elevating the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically crafted for wind power concrete towers, boasts an exterior cable designed for unmatched performance. The sheath's thickness and grease formulation can be tailored to meet precise user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's silhouette to be distinctly visible. It adheres to rigorous quality standards, ensuring the absence of air pockets, mechanical imperfections, cracks, or visible wrinkles.
Product Application
Our versatile product is designed for use in Wind Power and Water Conservancy,
as well as Hydro-power Stations.
Notably, it is a vital component in the South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
