Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand from Tianjin Wasungen Metal Products Co., Ltd. is a cutting-edge solution designed with anti-corrosion grease and sheath for maximum durability. Perfect for water conservancy and hydro-power projects, this product is now increasingly vital in towering wind power projects, where the height often exceeds 120m. The unbonded prestressed steel strand is preferred for concrete towers with external prestressing technology due to its outstanding corrosion and fatigue resistance, offering enhanced wind resistance and extended service life.
In alignment with the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have revolutionized the design to streamline the sheath tensile property test method. This innovation not only boosts the practicality but also optimizes the performance of the sheath, ensuring standardized quality and enhancing the project's safety and reliability.


Product Characteristics

Our unbonded steel strand is meticulously designed for the outer cable of wind power concrete towers. The sheath and grease thickness can be customized to meet specific technical requirements, featuring a dense, smooth surface that clearly outlines the steel strand. The sheath quality adheres to stringent standards, preventing air holes, mechanical damage, cracks, and noticeable wrinkles.
