Product Introduction
Discover the remarkable 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand, an innovative marvel meticulously crafted with anti-corrosion grease and a robust sheath. This exceptional product finds its prime application in water conservancy and hydro-power projects. With the burgeoning rise of wind power ventures, where tower constructions soar to heights of 120 meters and beyond, our unbonded prestressed steel strand has become indispensable. It seamlessly integrates into concrete towers employing external prestressing technology, offering unparalleled advantages such as exceptional corrosion and fatigue resistance, thus significantly enhancing wind resistance and extending the lifespan of structures.
Adhering to the rigorous standards set by JG/T 161-2016 for Unbonded Prestressed Steel Strand, we have ingeniously innovated our design. This evolution simplifies the test method for sheath tensile properties while greatly enhancing practicality, making it more user-friendly. The performance of our sheath is further optimized to ensure consistency in quality. This not only effectively standardizes sheath quality but also fortifies the safety parameters of your projects.
Product Characteristics
Our unbonded steel strand for wind power concrete towers is encapsulated in a meticulously designed outer cable sheath. Tailored to meet users' technical requirements, the sheath and grease thickness are customizable. The sheath's surface is dense, smooth, and clearly outlines the steel strand, ensuring an impeccable quality with no air holes, mechanical damage, cracks, or pronounced wrinkles. This precision meets the highest standards of surface excellence.
