Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is a remarkable, corrosion-resistant solution engineered for demanding hydro-power and water conservancy projects. As the wave of wind power projects rises, with towering structures reaching and exceeding 120m, these steel strands find pivotal applications. They are integral to concrete towers employing external prestressing technology, boasting exceptional corrosion and fatigue resistance to enhance wind resistance and significantly extend service life.
Complying with JG/T 161-2016 Unbonded Prestressed Steel Strand standards, we've reimagined the design to streamline the sheath tensile property testing method, enhancing practicality and user-friendliness. Our innovative approach optimizes sheath performance, rigorously standardizes quality, and ensures superior safety for your projects.


Product characteristics

Designed for the exterior of wind power concrete towers, our unbonded steel strand is customizable to meet specific technical needs, with sheath and grease thickness tailored to user specifications. Offering a dense and smooth sheath surface, the visibility of the steel strand silhouette is maintained, ensuring the highest surface quality standards—free from air holes, mechanical damage, cracks, and noticeable 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
