Product Introduction
Introducing our remarkable 1x7 structure unbonded prestressed steel strand, offered in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Expertly crafted with an anti-corrosion grease coating and encased in a robust sheath, this strand is tailored for excellence in water conservancy and hydro-power endeavors. As wind power initiatives ascend in prominence, our steel strands are indispensable in erecting majestic wind power towers, reaching impressive heights beyond 120 meters. These concrete towers, fortified with external prestressing, leverage the steel strand's exceptional corrosion and fatigue resistance, thereby fortifying wind endurance and prolonging the towers' lifespan.
Our design philosophy is rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've transformed the design to streamline the testing of the sheath's tensile properties, thereby enhancing its practical application and simplifying theadvancement of sheath performance. This groundbreaking innovation not only standardizes the sheath quality but also significantly elevates the safety and durability of the entire project.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an outer cable engineered for peak performance. With customizable sheath thickness and grease composition, it adapts to precise user specifications. The sheath's surface boasts an impeccable density and smoothness, ensuring the strand's outline is distinctly visible. Adhering to rigorous quality standards, it is devoid of air holes, mechanical damage, cracks, or visible wrinkles.
Product Application
The scope of application spans across Wind Power, Water Conservancy,
and Hydro-power Stations,
including the South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydro-power initiatives.
