Product Introduction
Introducing our top-tier 1x7 structure unbonded prestressed steel strand, tailored for precision in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Masterfully engineered, this strand is treated with superior anti-corrosion grease and encased in a robust sheath, making it the perfect choice for pioneering water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands play a crucial role in the construction of towering wind power towers, often exceeding heights of 120 meters. These concrete towers, utilizing advanced external prestressing methods, capitalize on the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue. This enhances wind resistance and significantly extends the durability of the towers.
Our state-of-the-art product design aligns with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively redesigned the testing process to seamlessly evaluate the tensile properties of the sheath, thereby optimizing its practical usage and augmenting theadvancement of sheath performance. This groundbreaking advancement not only rigorously standardizes sheath quality but also considerably elevates the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically engineered for wind power concrete towers, features an exterior cable designed for ultimate performance. The thickness of the sheath and the grease formulation can be customized to precisely meet user specifications. Its surface is meticulously crafted to be dense and smooth, with the silhouette of the steel strand clearly visible. It adheres to strict quality standards, ensuring no air holes, mechanical flaws, cracks, or visible wrinkles.
Product Application
Our cutting-edge products find their applications in the dynamic fields of Wind Power and Water Conservancy,
as well as in Hydro-power Stations.
They are also crucial for projects like The South-North Water Transfer Project,
River Channels, and other crucial nationally significant water conservancy and hydropower initiatives.
