Product Introduction
Introducing the unparalleled quality of our 1x7 structure unbonded prestressed steel strand, crafted with precision in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This strand is ingeniously enhanced with anti-corrosion grease and encased in a durable sheath, making it perfect for water conservancy and hydro-power projects. As the wind power industry continues to expand, our steel strands are indispensable in the construction of towering wind power structures, exceeding heights of 120 meters. These concrete towers employ advanced external prestressing methods, utilizing the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance to enhance wind resistance and extend the tower's longevity.
Our innovative product design is in strict accordance with the revered JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. The design is optimized to simplify the testing process for sheath tensile properties, significantly improving its practical use while facilitatingthe enhancement of sheath performance. This groundbreaking development not only ensures the standardization of sheath quality but also greatly enhances the safety and structural integrity of entire projects.
Product Characteristics
Our state-of-the-art unbonded steel strand, specifically designed for wind power concrete towers, features an expertly crafted exterior cable for optimal performance. The sheath's thickness and grease formulation can be tailored to meet specific customer specifications. Its surface is impeccably dense and smooth, allowing for clear visibility of the steel strand's shape. It meets rigorous quality standards, ensuring no presence of air holes, mechanical flaws, cracks, or visible creases.
Product Application
Perfectly suited for Wind Power and Water Conservancy,
as well as Hydro-power Stations,
including the monumental South-North Water Transfer Project,
River Channels, and other major national water conservancy and hydropower ventures.
