Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is a cutting-edge solution, engineered with special anti-corrosion grease and a protective sheath. Primarily serving essential water conservancy and hydro-power projects, this product is increasingly utilized in the burgeoning field of wind power. With construction heights of wind power towers now reaching or surpassing 120m, the deployment of unbonded prestressed steel strands in concrete towers with external prestressing technology is on the rise. These products offer outstanding corrosion resistance and fatigue durability, enhancing wind resistance capabilities and significantly extending the service life of projects.
Inspired by the standard JG/T 161-2016 for Unbonded Prestressed Steel Strands, we have revolutionized the design to streamline the testing methods for sheath tensile properties, thereby enhancing their practical application and functionality. Optimize sheath performance, rigorously standardize the quality of the sheath, and elevate the quality safety standards across projects.


Product Characteristics

Our unbonded steel strand, tailored for the outer cables of wind power concrete towers, is ingeniously customizable in sheath thickness and grease application, as per technical user requirements. The sheath's surface is impeccably dense and smooth, with the steel strand's contours discernible. Surface quality achieves industry benchmarks by eliminating air holes, mechanical damage, cracks, and noticeable wrinkles, ensuring superior performance.


Product Application

Widely applicable in Wind Power, Water Conservancy
Integral to Hydro-power Stations
A pivotal component of the South-North Water Transfer Project
Vital for River Channels and other National Key Water Conservancy and Hydropower Projects
