Product Introduction
Introducing our high-caliber 1x7 structure unbonded prestressed steel strand, available in precise measurements of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly engineered strand is infused with anti-corrosion grease and encased in a robust sheath, making it an ideal choice for water conservancy and hydro-power projects. As the wind power industry continues its rapid expansion, our steel strands have become essential in constructing towering wind power structures, often reaching heights of over 120 meters. The concrete towers, utilizing advanced external prestressing techniques, benefit from the unbonded prestressed steel strand's exceptional resistance to corrosion and fatigue, significantly enhancing wind resistance and extending the tower's lifespan.
Our innovative product design adheres to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have refined the design to streamline the testing process for the sheath's tensile properties, thereby improving its practical application and facilitating theenhancement of sheath performance. This breakthrough not only effectively standardizes sheath quality but also significantly elevates the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically tailored for wind power concrete towers, features an external cable meticulously designed for optimal performance. The sheath's thickness and grease formula can be customized to meet specific user requirements. Its surface is impeccably dense and smooth, making the steel strand's silhouette distinctly visible. It adheres to stringent quality standards, ensuring no air holes, mechanical defects, cracks, or noticeable wrinkles are present.
Product Application
The fields of application extend to Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
