Product Introduction
Introducing our outstanding 1x7 structure unbonded prestressed steel strand, available in the precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Expertly designed, each strand is meticulously coated with advanced anti-corrosion grease and encased within a robust sheath. This product is ideally suited for cutting-edge water conservancy and hydro-power projects. As the global demand for wind power surges, our high-quality steel strands are playing a pivotal role in the construction of towering wind power towers, which often exceed impressive heights of 120 meters. The application of external prestressing technology in these concrete towers harnesses the unbonded prestressed steel strand’s extraordinary corrosion and fatigue resistance. This significantly enhances wind resistance and extends the towers’ operational lifespan.
Our product design is firmly based on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have reimagined the design to streamline the testing process for the sheath's tensile properties, thereby increasing its practical utility and simplifying theadvancement of sheath performance. This groundbreaking innovation not only effectively standardizes sheath quality but also notably boosts the safety and integrity of every project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers is equipped with an outer cable meticulously crafted for peak performance. The sheath’s thickness and grease formulation can be tailored to meet specific user needs. The sheath's surface is flawlessly dense and impeccably smooth, revealing the steel strand’s outline. It adheres to stringent quality benchmarks, ensuring the absence of air holes, mechanical damage, cracks, or visible wrinkles.
Product Application
The areas of application span across Wind Power, and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
