Product Introduction
Introducing our remarkable 1x7 structure unbonded prestressed steel strand, available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This intricately engineered strand comes with a special coating of anti-corrosion grease and is encased in a robust sheath. It is the ideal choice for water conservancy and hydro-power projects. With the increasing momentum for wind power advancements, our steel strands have found significant usage in constructing grand wind power towers, often towering beyond heights of 120 meters. The concrete towers, leveraging external prestressing technology, benefit from the unbonded prestressed steel strand's exceptional resistance to corrosion and fatigue—thereby amplifying wind resistance and prolonging the longevity of the towers.
Our product design is firmly rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovated upon the design to streamline the testing process for the sheath's tensile properties, thus enhancing its practical usability and facilitating theadvancement of sheath performance. This novel approach not only efficiently standardizes the sheath quality but also significantly bolsters the safety and quality of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously crafted for superior performance. The sheath's thickness and grease composition can be tailored to meet specific user requirements. The sheath's surface is meticulously dense and smooth, allowing the steel strand's outline to be discernibly visible. It adheres to rigorous quality benchmarks, ensuring there are no air holes, mechanical damage, cracks, or conspicuous wrinkles.
Product Application
The scope of application spans Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
