Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, meticulously crafted for precision and performance. Available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, this strand is enriched with an anti-corrosion grease and wrapped in a durable sheath. Its superior design is perfect for water conservancy and hydro-power projects. As the wind power industry expands, our steel strands have become crucial for constructing towering wind power towers, often exceeding heights of 120 meters. These concrete towers, using advanced external prestressing techniques, capitalize on the steel strand's remarkable resistance to corrosion and fatigue, enhancing wind resistance and extending the tower's lifespan.
Our innovative product design complies rigorously with the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to simplify the testing process of the sheath's tensile properties, thereby improving its practical utility and facilitating theenhancement of sheath performance. This innovation not only standardizes sheath quality effectively but also significantly elevates the safety and integrity of the entire project.
Product Characteristics
Engineered for wind power concrete towers, our unbonded steel strand features an outer cable designed for optimal performance. The sheath's thickness and grease composition are customizable to meet specific requirements. The surface is impeccably smooth and dense, allowing the steel strand's profile to be clearly visible. It meets stringent quality standards, ensuring there are no air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
Our product finds its application in the fields of Wind Power and Water Conservancy,
as well as Hydro-power Stations.
Notably, it plays a pivotal role in the South-North Water Transfer Project,
River Channels, and various other nationally significant water conservancy and hydropower initiatives.
