Product Introduction
Introducing our remarkable 1x7 structure unbonded prestressed steel strand, available in sizes of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Carefully engineered, this strand is coated with high-performance anti-corrosion grease and protected by a robust sheath, making it the ideal choice for water conservancy and hydro-power projects. As the demand for wind power rises, our steel strands find increasing use in constructing monumental wind power towers, often soaring beyond 120 meters. These concrete towers, utilizing advanced external prestressing technology, leverage the unbonded prestressed steel strand's extraordinary corrosion and fatigue resistance, thereby significantly boosting wind resistance and prolonging the towers' lifespan.
Our product design is based on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've innovated the design to streamline the testing process for the sheath's tensile properties, enhancing practical usability and facilitating theadvancement of sheath performance. This innovation not only standardizes sheath quality but also substantially elevates the safety and quality of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously designed for peak performance. The sheath's thickness and grease formulation can be tailored to meet precise user specifications. Its surface is flawlessly dense and smooth, revealing the steel strand's outline. It aligns with rigorous quality standards, ensuring the absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
The fields of application include Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
