Product Description

Product Description

Product Introduction

The advanced 1x7 structure of our unbonded prestressed steel strands, available in diameters of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, is specially engineered with anti-corrosion grease and a protective sheath. Widely implemented in water conservancy and hydro-power projects, our products have recently seen increased usage in the booming wind power sector. As the construction height of wind power towers now often exceeds 120m, the demand for concrete towers utilizing external prestressing technology has surged. Our unbonded prestressed steel strands offer superior corrosion and fatigue resistance, enhancing wind resistance and significantly extending the lifespan of these structures.
Adhering to the JG/T 161-2016 standard for Unbonded Prestressed Steel Strands, we have innovated our design to streamline the testing method for sheath tensile properties, thereby enhancing practicality and facilitating the performance of the sheath. This innovation effectively standardizes sheath quality and boosts the overall safety and reliability of the project.


Product Characteristics

Our unbonded steel strands are tailored for use in the outer cables of wind power concrete towers. The thickness of the sheath and grease can be customized according to specific technical requirements of our clients. The sheath surface is meticulously designed to be dense and smooth, ensuring the steel strand's outline is visible. We guarantee surface quality that meets stringent standards, free from air holes, mechanical damage, cracks, and visible wrinkles.
