Product Introduction
Discover the pinnacle of engineering excellence with our 1x7 structure unbonded prestressed steel strand, available in the versatile dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This strand is expertly crafted with a high-performance anti-corrosion grease coating and encased in a robust sheath, making it indispensable for water conservancy and hydro-power projects. As the demand for sustainable energy sources escalates, our steel strands are pivotal in the construction of magnificent wind power towers that soar beyond 120 meters. These concrete towers leverage advanced external prestressing technology, utilizing the unbonded prestressed steel strand's superior corrosion and fatigue resistance. This technological marvel not only fortifies wind resistance but also significantly prolongs the lifespan of these towering structures.
Our product design is rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've reimagined the design to streamline the testing process of the sheath's tensile properties, thereby enhancing its practical usability and ensuring seamless integration into various projects.By advancing sheath performance, this innovation establishes a new benchmark for sheath quality. It not only ensures standardized excellence but also elevates the safety and quality of construction, making it an ideal choice for any demanding project.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an outer cable engineered for peak performance. The sheath's thickness and grease composition can be tailored to meet specific customer needs. Its surface is meticulously dense and smooth, allowing the steel strand's outline to be discernible. It complies with rigorous quality standards, guaranteeing the absence of air holes, mechanical damage, cracks, or significant wrinkles, thus ensuring unparalleled reliability.
Product Application
Our products find application in diverse sectors such as Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other major national water conservancy and hydropower projects.
