Product Introduction
Introducing our outstanding 1x7 structured unbonded prestressed steel strand, available in a variety of sizes: 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This strand is superbly crafted, coated with premium anti-corrosion grease, and encased in a robust sheath, making it the ideal choice for water conservancy and hydro-power projects. As the demand for wind power surges, our steel strands are increasingly favored for constructing majestic wind power towers, which often soar beyond 120 meters. These towers, leveraging cutting-edge external prestressing technology, benefit from the strand's exceptional resistance to corrosion and fatigue, thereby enhancing wind resistance and significantly prolonging their lifespan.
Our product design is based on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively redesigned the process to streamline the testing of the sheath's tensile properties, thereby boosting its practical usability and simplifying theenhancement of sheath performance. This innovative approach not only sets a benchmark for sheath quality but also elevates the safety and excellence of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers is engineered with an outer cable designed for peak performance. The sheath's thickness and grease composition can be tailored to meet specific user needs. The sheath's surface is densely packed and smooth, allowing the steel strand's outline to be distinctly visible. It adheres to the highest quality standards, ensuring freedom from air holes, mechanical damage, cracks, or visible wrinkles.
Product Application
Our products are ideally suited for applications in Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally essential water conservancy and hydropower projects.
