Product Description

Product Description

Product Introduction

Our premium 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is an advanced, specially designed prestressed steel bar featuring anti-corrosion grease and a robust sheath. This product is indispensable in water conservancy and hydropower projects. With the rise of wind power projects, where tower heights frequently reach or surpass 120m, the unbonded prestressed steel strand is increasingly employed in concrete towers utilizing external prestressing technology. Its unparalleled corrosion resistance and fatigue resistance significantly enhance wind resistance and extend service life, making it an essential choice for modern engineering.
Adhering to the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have ingeniously redefined the design to streamline the test method of sheath tensile property, boosting its practicability and facilitating ease of use. This innovation effectively enhances sheath performance, rigorously standardizing quality and ensuring the utmost safety and reliability in project execution.


Product Characteristics

For the outer cable of wind power concrete towers, our unbonded steel strand is meticulously crafted with customizable sheath thickness and grease levels to meet user technical specifications. The sheath surface is dense, smooth, and precisely outlines the steel strand beneath. Our commitment to excellence ensures the surface quality is impeccable, free from air holes, mechanical damage, cracks, and prominent wrinkles, achieving superior standards.


Product Application

Ideal for Wind Power and Water Conservancy Projects.
Perfect for Hydro-power Stations.
Essential for the South-North Water Transfer Project.
Crucial for River Channel and other National Key Water Conservancy and Hydropower Projects.
