Product Introduction
Introducing our premier 1x7 structure unbonded prestressed steel strand, meticulously designed in specific dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This finely engineered strand is enriched with anti-corrosion grease and encased in a durable sheath, making it the perfect choice for water conservancy and hydro-power projects. As the wind power industry flourishes, our steel strands have become essential for constructing towering wind power structures, frequently exceeding heights of 120 meters. The concrete towers, employing innovative external prestressing techniques, benefit from the unbonded prestressed steel strand's remarkable corrosion and fatigue resistance, thereby bolstering wind resistance and extending the longevity of these monumental towers.
Our state-of-the-art product design strictly adheres to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovated the design to optimize the testing process for the sheath's tensile properties, thereby enhancing its practical applications and simplifyingthe enhancement of sheath performance. This breakthrough advancement not only standardizes sheath quality effectively but also significantly elevates the safety and integrity of the complete project.
Product Characteristics
Our unbonded steel strand, crafted for wind power concrete towers, features an external cable masterfully engineered for optimal performance. The sheath's thickness and grease composition can be customized to meet exact user specifications. Its surface is impeccably dense and smooth, making the steel strand's shape visibly distinct. It meets strict quality benchmarks, guaranteeing no presence of air holes, mechanical defects, cracks, or visible wrinkles.
Product Application
The application domains encompass 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 initiatives.
