Product Introduction
Introducing our unrivaled 1x7 structure unbonded prestressed steel strand, meticulously crafted for excellence. Available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, this strand is expertly coated with premium anti-corrosion grease and encased in a robust sheath. It stands as the ideal solution for water conservancy and hydro-power projects. With the surge in wind power demand, our steel strands are increasingly pivotal in erecting towering wind power towers, often reaching beyond 120 meters. These concrete towers, employing cutting-edge external prestressing technology, benefit from the strand's exceptional corrosion and fatigue resistance, thereby boosting wind resistance and prolonging the tower's lifespan.
Our product design adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design, streamlining the testing process for the sheath's tensile properties, thus enhancing its practical usability, and facilitating theadvancement of sheath performance. This groundbreaking innovation not only effectively standardizes sheath quality but also significantly elevates the safety and overall excellence of any project.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an outer cable crafted for peak performance. The sheath's thickness and grease composition can be customized to meet specific user requirements. Its surface is impeccably smooth and dense, ensuring the steel strand's outline is visible. It meets rigorous quality standards, ensuring no air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
Our applications span across Wind Power, and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and various nationally prioritized water conservancy and hydropower initiatives.
