Product Introduction
Introducing our premium 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 imbued with anti-corrosion grease and cloaked in a resilient sheath, rendering it ideal for water conservancy and hydro-power ventures. As the wind power industry continues its dynamic expansion, our steel strands have become essential in erecting soaring wind power towers, often surpassing 120 meters in height. The concrete towers, utilizing advanced external prestressing techniques, capitalize on the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thereby fortifying wind resistance and prolonging the tower's durability.
Our cutting-edge product design adheres meticulously to the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have transformed the design to streamline the testing process for the sheath's tensile qualities, thereby enhancing its practical application and facilitating theadvancement of sheath performance. This innovative breakthrough not only effectively standardizes sheath quality but also significantly boosts the safety and integrity of the overall project.
Product Characteristics
Our unbonded steel strand, crafted specifically for wind power concrete towers, features an exterior cable meticulously engineered for peak performance. The sheath's thickness and grease formula are customizable to align with specific user needs. Its surface is flawlessly dense and smooth, making the steel strand's silhouette discernible. It complies with stringent quality standards, ensuring an absence of air holes, mechanical imperfections, cracks, or noticeable wrinkles.
Product Application
The fields of application include Wind Power and Water Conservancy,
alongside Hydro-power Stations.
The renowned South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower initiatives.
