Product Introduction
Allow us to present our outstanding 1x7 structure unbonded prestressed steel strand, available in precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Carefully crafted for excellence, each strand is coated with superior anti-corrosion grease and encapsulated in a robust sheath, making it an ideal solution for water conservancy and hydro-power projects. As the demand for renewable energy soars, our steel strands are increasingly sought after in the construction of imposing wind power towers, often surpassing 120 meters in height. These concrete towers leverage external prestressing technology, ensuring unmatched corrosion and fatigue resistance, which enhances wind resistance and significantly extends the lifespan of these monumental structures.
Our product design is rooted in the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered an innovative design approach tailored to streamline the testing process for the tensile properties of the sheath. This enhancement not only extends its practical usability but also facilitates theadvancement of sheath performance. This groundbreaking innovation sets a new benchmark by systematically standardizing the quality of the sheath, thereby significantly boosting the safety and overall quality of projects.
Product Characteristics
Our unbonded steel strand, tailored for wind power concrete towers, features an outer cable expertly crafted for peak performance. The sheath's thickness and grease composition are tailored to meet individual user specifications. Its surface is flawlessly dense and smooth, allowing the steel strand's outline to be discernible. Rigorous quality standards are upheld, ensuring the absence of air holes, mechanical imperfections, cracks, or noticeable wrinkles.
Product Application
The range of application extends to 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.
