Product Introduction
Introducing our top-tier 1x7 structure unbonded prestressed steel strand, offered in precise dimensions including 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This meticulously engineered strand, infused with anti-corrosion grease and enveloped in a durable sheath, is perfectly suited for water conservancy and hydro-power projects. As the wind power industry rapidly expands, our steel strands have become essential in constructing towering wind power towers, often exceeding 120 meters. Concrete towers, utilizing advanced external prestressing techniques, benefit from the unbonded prestressed steel strand's exceptional corrosion and fatigue resistance, thus enhancing wind resilience and extending the tower's lifespan.
Our innovative product design strictly complies with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design to simplify the testing of the sheath's tensile properties, thereby enhancing its practical utility and facilitating theprogression of sheath performance. This innovation not only standardizes sheath quality effectively but also considerably elevates the safety and structural integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically designed for wind power concrete towers, features an outer cable meticulously crafted for optimum performance. The sheath's thickness and grease composition are customizable to meet distinct user requirements. Its surface is impeccably dense and smooth, allowing the steel strand's silhouette to be clearly visible. It adheres to rigorous quality standards, guaranteeing the absence of air holes, mechanical flaws, cracks, or noticeable wrinkles.
Product Application
The applications span Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other critical national water conservancy and hydropower plans.
