Product Introduction
Introducing the epitome of innovation in prestressed steel technology, our premium 1x7 structure unbonded prestressed steel strand is available in meticulous dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Skillfully manufactured, each strand is infused with anti-corrosion grease and enshrouded in a robust protective sheath, making it the perfect choice for water conservation and hydro-power projects. As the wind power industry flourishes, our steel strands are indispensable in the construction of towering wind power structures, often exceeding 120 meters in elevation. These concrete towers, employing advanced external prestressing techniques, rely on the unmatched corrosion and fatigue resistance of our unbonded prestressed steel strands, thereby enhancing wind resistance and significantly extending the lifespan of the towers.
Our state-of-the-art product design is compliant with the revered JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have meticulously refined the design to optimize the testing process for the tensile properties of the sheath, thereby significantly improving its practical application and streamlining theevolution of sheath performance. This groundbreaking development not only rigorously sets the standard for sheath quality but also dramatically elevates the safety and structural integrity of the entire project.
Product Characteristics
Our tailored unbonded steel strand for wind power concrete towers boasts an external cable that is meticulously engineered for optimal performance. The sheath's thickness and grease composition are adaptable to fulfill specific user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's silhouette to be clearly defined. It meets the highest quality standards, ensuring an absence of air voids, mechanical defects, fissures, or any visible creases.
Product Application
Our product applications span the dynamic fields of Wind Power and Water Conservancy,
alongside the pivotal Hydro-power Stations,
the monumental South-North Water Transfer Project,
River Channels, and other projects of national importance in water conservancy and hydropower.
