Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is a state-of-the-art solution featuring anti-corrosion grease and a robust sheath. These high-performance products are essential for water conservancy and hydro-power projects. With the recent surge in wind power projects, the construction heights of wind power towers now often exceed 120m. Increasingly, concrete towers utilizing external prestressing technology rely on unbonded prestressed steel strands. Renowned for their exceptional corrosion and fatigue resistance, these strands enhance wind resistance and extend the service life of structures.
Adhering to the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have redefined design protocols to streamline the testing methods for sheath tensile properties, enhancing both practicality and user convenience. Our innovations optimize sheath performance, rigorously standardize sheath quality, and elevate project safety standards.


Product characteristics

The unbonded steel strand used in the exterior cables of wind power concrete towers is meticulously designed to meet user-specific technical requirements for sheath thickness and grease application. The sheath surface is compact and smooth, revealing the steel strand's outline. Our high-quality surface finish guarantees the absence of air holes, mechanical damage, cracks, and noticeable wrinkles, adhering to the highest standards.


Product application

Wind power, water conservancy
Hydro-power Station
South-North Water Transfer project
River Channel and other national key water conservancy and hydropower projects
