Product Introduction
Introducing our superior 1x7 structure unbonded prestressed steel strand, meticulously crafted with precision in sizes of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This product is expertly imbued with an advanced anti-corrosion grease and enveloped in a robust sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry experiences significant growth, our steel strands have become essential components in constructing towering wind power towers, often exceeding impressive heights of 120 meters. The concrete towers utilize cutting-edge external prestressing techniques that capitalize on the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, enhancing wind resistance and extending the tower's longevity.
Our pioneering product design adheres to the respected JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovated the design to streamline the testing process for the sheath's tensile properties, thereby amplifying its practical utility and simplifying theadvancement of sheath performance. This innovation not only standardizes sheath quality effectively but also significantly heightens the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specially configured for wind power concrete towers, boasts an exterior cable engineered for maximal efficiency. The sheath's thickness and grease formula can be customized to meet specific user requirements. Its exterior is impeccably dense and smooth, making the silhouette of the steel strand distinctly visible. It complies with stringent quality benchmarks, guaranteeing the absence of air holes, mechanical flaws, cracks, or conspicuous wrinkles.
Product Application
The fields of application encompass Wind Power and Water Conservancy,
in addition to Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally significant water conservancy and hydropower projects.
