Product Introduction
Delve into the unparalleled excellence of our meticulously engineered 1x7 structure unbonded prestressed steel strand, available in the exact specifications of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterfully crafted strand is infused with anti-corrosive grease and enveloped in a robust sheath, making it the quintessential choice for water conservancy and hydro-power projects. As the wind power industry experiences a remarkable surge, our steel strands have become indispensable in the construction of towering wind power towers, often exceeding heights of 120 meters. The concrete towers, enhanced with external prestressing methods, capitalize on the unbonded prestressed steel strand's superior corrosion and fatigue resistance, thereby enhancing wind resistance and significantly extending the tower's lifespan.
Our innovative product design strictly adheres to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to optimize testing efficiency for the sheath's tensile properties, thereby amplifying its practical application and streamlining theadvancement of sheath performance. This innovation not only effectively standardizes sheath quality but also remarkably enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically designed for wind power concrete towers, boasts an exterior cable engineered to deliver optimal performance. The thickness of the sheath and the grease formulation can be tailored to meet distinct user requirements. Its surface is impeccably dense and smooth, revealing the silhouette of the steel strand. It strictly adheres to rigorous quality standards, ensuring no air holes, mechanical defects, cracks, or visible wrinkles are present.
Product Application
The versatile applications span across the realms of Wind Power and Water Conservancy,
along with Hydro-power Stations.
The monumental South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
