Product Introduction
Experience the unmatched strength and versatility of our 1x7 structure unbonded prestressed steel strand. Available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, this steel strand is expertly crafted for top-tier performance. Coated with premium anti-corrosion grease and encased in a resilient sheath, it’s the ideal choice for water conservancy and hydro-power projects. As wind power initiatives soar, our strands are pivotal in building wind power towers that often surpass 120 meters in height. Through the adoption of external prestressing technology, our steel strands significantly boost wind resistance and longevity, thanks to their exceptional corrosion and fatigue resistance.
Our cutting-edge design is firmly anchored on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've redefined the design to streamline the testing of the sheath's tensile properties, thereby enhancing practical usability and facilitating theupgradation of sheath performance. This advancement not only rigorously standardizes sheath quality but also markedly boosts the safety and excellence of the entire project.
Product Characteristics
Specifically crafted for wind power concrete towers, our unbonded steel strand features an outer cable designed for superior performance. The sheath's thickness and grease formula can be tailored to individual user needs. Its surface is flawlessly dense and smooth, allowing the steel strand's silhouette to appear. Compliant with rigorous quality standards, it is free from air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
Our product finds its remarkable applications in the realms of Wind Power and Water Conservancy,
not to mention its vital role in Hydro-power Stations.
It plays a crucial part in the South-North Water Transfer Project,
River Channels, and other high-priority national water conservancy and hydropower endeavors.
