Product Introduction
Introducing our top-tier, expertly engineered 1x7 structure unbonded prestressed steel strand. Available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, this strand is meticulously infused with anti-corrosion grease and enveloped in a robust sheath. Perfectly suited for water conservancy and hydro-power projects, it ensures unmatched durability and reliability. As the wind power sector continues to flourish, our steel strands are key in constructing towering wind power towers, often exceeding 120 meters in height. These concrete towers utilize advanced external prestressing techniques, leveraging the strand's exceptional corrosion and fatigue resistance. This innovative approach significantly enhances wind resistance and extends the tower's lifespan, ensuring optimal performance and longevity.
Our cutting-edge product design strictly follows the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to simplify the testing process for the sheath's tensile qualities, thus improving its practical application and usage.This advancement significantly elevates sheath performance. The breakthrough not only effectively standardizes sheath quality but also greatly enhances the overall project's safety and integrity, ensuring superior protection and reliability.
Product Characteristics
Our unbonded steel strand, specifically designed for wind power concrete towers, boasts an exterior cable engineered for maximum efficiency. The sheath's thickness and grease formulation can be tailored to meet precise user specifications. Its surface is impeccably dense and smooth, allowing the steel strand's silhouette to be easily discerned. It adheres to the highest quality standards, guaranteeing no air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
The fields of application extend to Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
