Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly engineered strand is infused with anti-corrosion grease and encased in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands have become essential in the construction of towering wind power structures, often exceeding a remarkable 120 meters in height. These concrete towers, utilizing cutting-edge external prestressing techniques, capitalize on the unbonded prestressed steel strand's superior resistance to corrosion and fatigue, thereby enhancing wind resistance and extending the tower’s longevity.
Our innovative product design strictly conforms to the highly respected JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to optimize the testing process for the sheath's tensile properties, thereby elevating its practical application and simplifying theenhancement of sheath performance. This groundbreaking advance not only effectively standardizes sheath quality but also dramatically enhances the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically designed for wind power concrete towers, features an exterior cable meticulously engineered for optimal performance. The sheath's thickness and grease formulation can be tailored to meet specific user demands. Its surface is impeccably dense and smooth, which allows the steel strand's contour to remain visible. It adheres to rigorous quality standards, ensuring the absence of air pockets, mechanical defects, cracks, or visible wrinkles.
Product Application
This versatile product finds applications in Wind Power and Water Conservancy,
as well as Hydro-power Stations.
It is pivotal in the South-North Water Transfer Project,
River Channels, and other nationally important water conservancy and hydropower undertakings.
