Product Introduction
Introducing our premium quality 1x7 structure unbonded prestressed steel strand, crafted with precision in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This exceptional strand, infused with anti-corrosion grease and enveloped in a durable sheath, is indispensable for water conservancy and hydro-power projects. As the wind power industry thrives, our steel strands play a vital role in the construction of towering wind power towers, reaching heights beyond 120 meters. These concrete towers, employing the advanced technique of external prestressing, benefit from the unbonded prestressed steel strand's remarkable corrosion and fatigue resistance. This innovation significantly enhances wind resistance and extends the longevity of the towers.
Our innovative product design is in full compliance with the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have redefined the design to simplify the testing process for the sheath's tensile properties, thereby elevating its practical application and promoting theenhancement of sheath performance. This groundbreaking improvement not only standardizes sheath quality but also dramatically increases the safety and reliability of the entire project.
Product Characteristics
Our unbonded steel strand, specifically designed for wind power concrete towers, features an exterior cable meticulously engineered for ultimate performance. The sheath's thickness and the grease formula can be tailored to meet individual user requirements. Its surface is impeccably dense and smooth, making the steel strand's outline easily discernible. Adhering to rigorous quality standards, it is free of air holes, mechanical flaws, cracks, or any noticeable wrinkling.
Product Application
The diverse fields of application encompass Wind Power and Water Conservancy,
in addition to Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other prominent national water conservancy and hydropower projects.
