Product Introduction
Presenting our top-tier 1x7 structure unbonded prestressed steel strand, crafted to perfection in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Expertly infused with anti-corrosion grease and encased within a robust sheath, this strand is the epitome of excellence for water conservancy and hydro-power projects. As the wind power industry experiences monumental growth, our steel strands become indispensable in constructing towering wind power towers, often exceeding 120 meters. These concrete towers, employing external prestressing techniques, capitalize on the unbonded prestressed steel strand's outstanding corrosion and fatigue resistance, enhancing wind resistance and extending the tower's lifespan.
Our groundbreaking product design proudly complies with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design, optimizing the testing procedures for the sheath's tensile properties, thereby elevating its practical use and application.This innovation not only rigorously standardizes sheath quality but also dramatically enhances the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically engineered for wind power concrete towers, boasts an exterior cable designed for optimal performance. With customizable sheath thickness and grease formula tailored to precise user requirements, its surface is impeccably dense and smooth, revealing the steel strand's contour. It meets strict quality regulations, ensuring a flawless finish free from air holes, mechanical defects, cracks, or conspicuous wrinkles.
Product Application
Ideal applications encompass Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally critical water conservancy and hydropower undertakings.
