Product Description

Product Description

Product Introduction

The 1x7 structure '12.7mm, 15.20mm, 15.70mm, 17.80mm' unbonded prestressed steel strand is a specialized prestressed steel bar featuring advanced anti-corrosion grease and a robust sheath. Ideal for water conservancy and hydro-power projects, these strands have recently gained prominence in wind power projects, especially as the construction height of wind power towers reaches or exceeds 120m. Increasingly, concrete towers using external prestressing technology are incorporating our unbonded prestressed steel strand. These products boast exceptional corrosion and fatigue resistance, significantly enhancing wind resistance and extending service life.
Aligned with the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we've revolutionized our design to streamline the test method for sheath tensile properties, thereby enhancing practicality and facilitating superior project outcomes. Our innovations effectively standardize sheath quality, ensuring enhanced performance and bolstering the overall safety and reliability of your projects.


Product Characteristics

The outer cable of wind power concrete towers employs our unbonded steel strand. The sheath's thickness and grease are customizable to meet your specific technical requirements. The sheath surface is dense, smooth, and reveals the steel strand outline, ensuring no air holes, mechanical damage, cracks, or noticeable wrinkles, thereby meeting stringent surface quality standards.


Product Application

Wind Power, Water Conservancy
Hydro-power Station
South-North Water Transfer Project
River Channel and other major national water conservancy and hydropower projects
