Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, meticulously available in precise measurements of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This masterfully engineered strand is infused with advanced anti-corrosion grease and encased in a durable sheath, making it the perfect choice for water conservancy and hydro-power initiatives. As the wind power industry experiences unprecedented growth, our steel strands have become indispensable in the construction of towering wind power structures, often exceeding heights of 120 meters. The concrete towers employ innovative external prestressing techniques, utilizing the unbonded prestressed steel strand's remarkable resistance to corrosion and fatigue, thus enhancing wind resilience and extending the tower's longevity.
Our state-of-the-art product design conforms to the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have revolutionized the design to simplify the testing procedure for the sheath's tensile properties, thereby amplifying its practical usability and streamlining theenhancement of sheath performance. This groundbreaking advancement not only ensures uniform sheath quality but also significantly elevates the safety and reliability of the entire project.
Product Characteristics
Our unbonded steel strand, crafted for wind power concrete towers, is equipped with an exterior cable that is meticulously designed for optimal performance. The sheath's thickness and grease formulation are customizable to meet specific user requirements. Its surface is impeccably dense and smooth, making the steel strand's profile easily distinguishable. It adheres to rigorous quality standards, guaranteeing the absence of air pockets, mechanical faults, cracks, or visible wrinkles.
Product Application
Our products find their application in the dynamic sectors of Wind Power and Water Conservancy,
as well as in Hydro-power Stations.
They are integral to the South-North Water Transfer Project,
River Channels, and other nationally vital water conservancy and hydropower projects.
