Product Description

Product Description

Product Introduction

The 1x7 structure unbonded prestressed steel strand, available in 12.7mm, 15.20mm, 15.70mm, and 17.80mm, is a premium prestressed steel bar enveloped in anti-corrosion grease and a robust sheath. Primarily utilized in water conservancy and hydropower projects, this exceptional product has seen growing adoption in wind power projects. The construction heights of these wind power towers often reach or exceed 120m. Increasingly, concrete towers leveraging external prestressing technology are turning to unbonded prestressed steel strands. These strands boast remarkable corrosion resistance and fatigue endurance, significantly enhancing wind resistance and extending the service life of structures.
Based on the rigorous JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have revolutionized our design. Our innovative approach simplifies the testing method for sheath tensile properties, thereby increasing practicability and ease of use. Our advancements in sheath performance meticulously standardize quality, ensuring the highest safety standards for your projects.


Product Characteristics

Our unbonded steel strand, specially designed for the outer cables of wind power concrete towers, meets the technical specifications of users. The sheath and grease thickness can be customized to meet these requirements. The sheath's dense and smooth surface reveals the precise outline of the steel strand. It adheres to stringent surface quality standards, ensuring no air holes, mechanical damage, cracks, or noticeable wrinkles are present.
