Product Description

Product Description

Comprehensive Product Introduction

The 1x7 structure '12.7mm, 15.20mm, 15.70mm, 17.80mm' unbonded prestressed steel strand is a specialized prestressed steel bar with advanced anti-corrosion grease and protective sheath. These products are essential in water conservancy and hydro-power projects. Recently, the burgeoning wind power sector has seen increased usage, with tower construction heights reaching or exceeding 120m. Unbonded prestressed steel strands are increasingly adopted for concrete towers employing external prestressing technology. These strands offer superior corrosion resistance and fatigue resistance, enhancing wind resistance and extending service life.
Aligned with the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have innovatively redesigned to simplify the sheath tensile property test method, enhancing practicability and efficiency. We have significantly enhanced the sheath performance, effectively standardizing the quality, and ensuring higher safety and reliability for your project.


Distinctive Product Features

For wind power concrete towers, the unbonded steel strand's outer cable is meticulously designed. The sheath and grease thickness can be tailored to meet user-specific technical requirements. The sheath surface is dense and smooth, revealing the steel strand outline. It adheres to stringent quality standards with no air holes, mechanical damage, cracks, or noticeable wrinkles.


Versatile Product Applications
