Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, available in the precise dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This expertly crafted strand is meticulously coated with anti-corrosion grease and encased in a resilient sheath, making it an ideal choice for water conservancy and hydro-power endeavours. With the increasing momentum for wind power advancements, our robust steel strands are pivotal in constructing towering wind power towers, often surpassing heights of 120 meters. These concrete towers, enhanced by external prestressing technology, leverage the unbonded prestressed steel strand's outstanding corrosion and fatigue resistance, which significantly boosts wind resistance and prolongs the lifespan of the towers.
Our product design is founded on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered a design that simplifies the testing process for the sheath's tensile properties, thereby enhancing its practical usability and facilitating theadvancement of sheath performance. This groundbreaking innovation not only standardizes the sheath quality but also substantially elevates the safety and integrity of the entire project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers features an outer cable meticulously crafted for peak performance. The sheath's thickness and grease formulation can be tailored to meet specific user demands. The sheath's surface is flawlessly dense and smooth, enabling the steel strand's outline to be discernible. It adheres to rigorous quality standards, ensuring the absence of air holes, mechanical impairments, cracks, or prominent 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 initiatives.
