Product Introduction
Introducing our premium 1x7 structure unbonded prestressed steel strand, crafted with meticulous precision for unmatched performance. Available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, this engineered masterpiece boasts anti-corrosion grease enveloped in a durable sheath. Ideal for water conservancy and hydro-power projects, it is indispensable in the wind power sector for constructing towering wind power towers over 120 meters high. These impressive concrete towers, employing external prestressing techniques, capitalize on the strand's superior corrosion and fatigue resistance, enhancing wind resistance and significantly extending tower longevity.
Our state-of-the-art product design strictly adheres to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have innovatively refined the design to simplify the sheath's tensile quality testing, elevating its practical application and contributing to theremarkable advancement of sheath performance. This pioneering development not only standardizes sheath quality but also immensely augments the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, specifically engineered for wind power concrete towers, features an exterior cable designed for optimal performance. The sheath's thickness and grease composition can be tailored to meet diverse user requirements. Its surface is impeccably smooth and dense, revealing the steel strand's silhouette with clarity. Adhering to rigorous quality standards, it guarantees an absence of air pockets, mechanical flaws, cracks, or prominent wrinkles.
Product Application
The application spectrum spans 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 ventures.
