Product Introduction
Discover our extraordinary 1x7 structure unbonded prestressed steel strand, available in versatile dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This meticulously crafted strand is enhanced with a protective anti-corrosion grease and wrapped in a robust sheath, making it the ideal solution for water conservancy and hydro-power infrastructure. As the demand for renewable energy surges, our steel strands are increasingly pivotal in the construction of monumental wind power towers, which often soar to impressive heights surpassing 120 meters. These concrete towers, employing advanced external prestressing technology, benefit significantly from the strand's exceptional corrosion and fatigue resistance—thereby boosting wind resilience and ensuring a prolonged structural lifespan.
Our product design adheres to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand, demonstrating our commitment to excellence. We've reimagined the design to streamline the evaluation of the sheath's tensile attributes, significantly enhancing its practical application and advancingthe performance of the sheath. This groundbreaking innovation not only standardizes sheath quality with precision but also elevates the safety and overall quality of projects, delivering unmatched reliability.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an exterior cable engineered for peak performance. The sheath's thickness and grease composition are fully customizable to align with unique user specifications. The sheath's surface is flawlessly smooth and dense, allowing the steel strand's silhouette to be discernible. It adheres to stringent quality benchmarks, guaranteeing an absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
This product is perfectly suited for a wide array of applications, including Wind Power and Water Conservancy,
and also excels in Hydro-power Stations.
It plays a critical role in significant projects like the South-North Water Transfer Project,
River Channels, alongside other nationally prioritized water conservancy and hydropower projects.
