Product Introduction
Introducing our state-of-the-art 1x7 structure unbonded prestressed steel strand, precisely available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This meticulously engineered strand is enhanced with premium anti-corrosion grease and enveloped in a robust protective sheath, making it the ideal choice for water conservancy and hydro-power projects. As the demand in the wind power sector continues to rise, our steel strands play a crucial role in the construction of towering wind power structures, often exceeding heights of 120 meters. These concrete towers, utilizing advanced external prestressing techniques, benefit from the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, which in turn reinforces wind resistance and extends the longevity of the tower.
Our innovative product design is aligned with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing process for the tensile properties of the sheath, thereby augmenting its practical usage and facilitating theevolution of sheath performance. This innovative development not only standardizes sheath quality but also substantially enhances the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand, designed specifically for wind power concrete towers, features an exterior cable expertly crafted for optimal performance. The sheath's thickness and grease composition can be custom-tailored to meet specific user requirements. Its surface is impeccably dense and smooth, ensuring the distinct silhouette of the steel strand is visible. It adheres to rigorous quality standards, guaranteeing no air holes, mechanical defects, cracks, or visible 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 significant water conservancy and hydropower projects.
