Product Introduction
Presenting our superior 1x7 structure unbonded prestressed steel strand, offered in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This strand is expertly designed with anti-corrosion grease and encased in a resilient sheath, making it the exemplary solution for water conservancy and hydro-power endeavors. As the demand for wind power surges, our steel strands are crucial in constructing monumental wind power towers, often surpassing 120 meters. The integration of external prestressing technology with concrete towers leverages the unbonded prestressed steel strand’s extraordinary corrosion and fatigue resistance, enhancing wind resistance and significantly extending the towers’ longevity.
Our product is ingeniously crafted based on the esteemed JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We have pioneered a design that streamlines the testing process for the sheath's tensile properties, thereby enriching its practical applicability and facilitating theadvancement of sheath performance. This innovation not only effectively standardizes sheath quality but also substantially boosts the safety and quality of the comprehensive project.
Product Characteristics
Our unbonded steel strand for wind power concrete towers is distinguished by an outer cable meticulously engineered for optimal performance. The sheath's thickness and grease composition are adaptable to meet unique user requirements. Its surface is flawlessly dense and smooth, rendering the steel strand's outline visible. It adheres to stringent quality standards, eliminating air holes, mechanical damages, cracks, or conspicuous wrinkles.
Product Application
The application realms include 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.
