Product Introduction
Delve into the engineering marvel of the 1x7 structure with dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This unbonded prestressed steel strand is a groundbreaking innovation, embedded with an anti-corrosion grease and a protective sheath. Designed for the rigors of water conservancy and hydro-power projects, this product is now seeing rising applications in the burgeoning wind power sector. With the construction heights of wind power towers now often reaching or surpassing 120m, the demand for external prestressing technology has escalated. Our unbonded prestressed steel strand delivers outstanding corrosion and fatigue resistance, enhancing wind resistance and substantially extending the lifespan of structures.
Pioneering advancements have been made to the JG/T 161-2016 Unbonded Prestressed Steel Strand standards. Our innovative designs streamline the testing of sheath tensile properties, augmenting practicality and ease of use. Our revolutionary design effectively enhances sheath performance, rigorously standardizing quality, and reinforcing project safety and integrity.
Product characteristics
Specially crafted for the outer cables of wind power concrete towers, our unbonded steel strand is fully customizable. The sheath's thickness and the protective grease are tailored to meet specific technical demands. With a dense, smooth surface, the sheath reveals the outline of the steel strand beneath. Ensuring impeccable quality, our sheath is free from air holes, mechanical damage, cracks, and significant wrinkles, meeting the highest standards of surface excellence.
