Product Introduction
Introducing our exceptional 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 enriched with anti-corrosion grease and enveloped in a resilient sheath, making it an outstanding choice for water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands have become indispensable in constructing towering wind power towers that frequently reach heights surpassing 120 meters. The concrete towers leverage external prestressing techniques, utilizing the unbonded prestressed steel strand's remarkable corrosion and fatigue resistance to significantly enhance wind resistance and extend the tower's longevity.
Our innovative product design strictly adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to streamline the testing process for the sheath's tensile properties, thereby amplifying its practical application and facilitating theadvancement of sheath performance. This pioneering breakthrough not only effectively standardizes sheath quality but also considerably elevates the safety and integrity of the overall project.
Product Characteristics
Our specialized unbonded steel strand, crafted for wind power concrete towers, boasts an exterior cable meticulously designed for optimal performance. The sheath's thickness and grease formula are customizable to meet specific user requirements. Its surface is impeccably smooth and dense, making the steel strand's silhouette clearly discernible. It adheres to stringent quality standards, ensuring the absence of air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
The applications span across Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
