Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand, meticulously engineered to meet exacting standards in diameters of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This high-performance strand boasts an anti-corrosion grease formulation encased in a robust sheath, making it exceptionally suitable for water conservancy and hydro-power projects. As the wind power industry continues its exponential growth, our steel strands emerge as critical components in the construction of towering wind power structures, often reaching heights exceeding 120 meters. The concrete towers, utilizing advanced external prestressing methods, capitalize on the unbonded prestressed steel strand's superior corrosion and fatigue resistance, greatly enhancing wind resilience and extending tower longevity.
Our innovative product design is aligned with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing process for the sheath's tensile properties, significantly enhancing its practical usability and driving theadvancement of sheath performance. This groundbreaking approach not only ensures consistent sheath quality but also elevates the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, expertly crafted for application in wind power concrete towers, features an exterior cable meticulously engineered for optimal performance. The sheath's thickness and grease composition are highly customizable to meet specific customer requirements. Its surface is impeccably dense and smooth, ensuring the steel strand's silhouette remains distinct. It complies with rigorous quality standards, guaranteeing the absence of voids, mechanical flaws, cracks, or noticeable wrinkles.
Product Application
The application domains include Wind Power and Water Conservancy,
as well as Hydro-power Stations,
The South-North Water Transfer Project,
River Channels, in addition to other nationally important water conservancy and hydroelectric initiatives.
