Product Description

Product Description

Product Introduction

Discover the engineering marvel of our 1x7 structure unbonded prestressed steel strand, available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This exceptional steel bar is expertly crafted with anti-corrosion grease and a protective sheath, making it indispensable in water conservancy and hydro-power projects. As wind power projects soar in popularity, with tower heights reaching or surpassing 120m, our unbonded prestressed steel strand becomes crucial for concrete towers utilizing external prestressing technology. It offers outstanding corrosion resistance and fatigue durability, significantly enhancing wind resistance and extending the service life of structures.
Drawing inspiration from the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have ingeniously redesigned our product to streamline the testing method of the sheath's tensile properties, thereby boosting its practical application and usability. This innovation effectively optimizes the sheath's performance, rigorously standardizes its quality, and significantly elevates the safety standards of your construction projects.


Product Characteristics

Our unbonded steel strand, tailored for the external cables of wind power concrete towers, offers customizable sheath thickness and grease application to meet specific technical demands. The sheath's surface is impeccably dense and smooth, clearly delineating the steel strand's outline. It meets stringent standards with no air holes, mechanical damage, cracks, or conspicuous wrinkles, ensuring superior surface quality.
