Product Introduction
Introducing our outstanding 1x7 structure unbonded prestressed steel strand, available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is enveloped in anti-corrosion grease and a robust sheath, making it the ideal choice for water conservancy and hydro-power projects. As the demand for wind power solutions surges, our steel strands are being used extensively in constructing wind power towers, often reaching formidable heights of over 120 meters. These concrete towers, utilizing cutting-edge external prestressing technology, benefit from the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance. This, in turn, enhances wind resistance and prolongs the lifespan of the towers significantly.
Our product design is firmly rooted in the renowned JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing process of the sheath's tensile properties, thereby augmenting its practical usability and facilitating theadvancement of sheath performance. This innovation not only sets a benchmark for sheath quality but also significantly raises the safety and quality standards of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable designed for top-tier performance. The sheath's thickness and grease composition can be tailored to meet specific user needs. The sheath's surface is impeccably smooth and dense, ensuring the steel strand's outline is discernible. It adheres to rigorous quality standards, guaranteeing the absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
Our applications span across Wind Power, Water Conservancy,
and Hydro-power Stations,
including the monumental South-North Water Transfer Project,
River Channels, and other national priority water conservancy and hydropower projects.
