Product Description

Product Description

Product Introduction

The 1x7 structure '12.7mm, 15.20mm, 15.70mm, 17.80mm' unbonded prestressed steel strand is a specialized high-strength steel bar with anti-corrosion grease and a durable sheath. These exceptional products find their primary applications in water conservancy and hydro-power projects. With the rapid growth in wind power projects, the construction height of wind power towers now often reaches or even exceeds 120m. Consequently, more concrete towers are adopting external prestressing technology, utilizing our premium unbonded prestressed steel strand. Our products stand out with exceptional corrosion and fatigue resistance, significantly enhancing wind resistance and extending the lifespan of the structures.
Adhering to the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have innovatively refined our design to simplify the testing methods for sheath tensile properties, thereby enhancing practicality and facilitating improved performance. Our advancements have effectively standardized the sheath's quality, ensuring superior quality and safety for your projects.


Product Characteristics

The outer cable of wind power concrete towers employs our unbonded steel strand. The sheath's thickness and grease application can be customized according to user specifications. The sheath boasts a dense, smooth surface revealing the steel strand's outline. The surface quality adheres to stringent standards, ensuring no air holes, mechanical damage, cracks, or visible wrinkles.


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
