Product Introduction
Introducing our unparalleled 1x7 structure unbonded prestressed steel strand, available in versatile dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is coated in protective anti-corrosion grease and enveloped in a resilient sheath, making it the prime selection for water conservancy and hydro-power ventures. As the demand for sustainable wind energy surges, our steel strands are increasingly pivotal in erecting majestic wind power towers, often soaring beyond 120 meters. These concrete towers, empowered by advanced external prestressing technology, leverage the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thereby significantly enhancing wind endurance and prolonging the towers' operational longevity.
Our product design is founded on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered a groundbreaking design to streamline the testing process for the sheath's tensile properties, thereby elevating its practical application and supporting theadvancement of sheath performance. This innovation not only successfully standardizes the sheath quality but also markedly enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an external cable meticulously crafted for peak performance. The sheath's thickness and grease formulation are tailored to meet specific customer requirements. The sheath's surface is flawlessly dense and smooth, allowing the steel strand's outline to be visible. It adheres to rigorous quality standards, ensuring the absence of air holes, mechanical damage, cracks, or notable wrinkles.
Product Application
Our product serves a multitude of applications including Wind Power, and Water Conservancy,
as well as Hydro-power Stations.
Notably, it plays a crucial role in The South-North Water Transfer Project,
River Channels, and other high-priority national water conservancy and hydropower initiatives.
