Product Description

Product Description

Discover the Excellence of Our Customizable UNBONDED PC STRAND 7 Wires - Product Introduction

The 1x7 structure '12.7mm, 15.20mm, 15.70mm, 17.80mm' unbonded prestressed steel strand is an exceptional prestressed steel bar featuring anti-corrosion grease and a durable sheath. This versatile product is widely utilized in water conservancy and hydro-power projects. With the increasing prevalence of wind power projects, where the construction height of wind power towers reaches or exceeds 120m, the use of unbonded prestressed steel strand in concrete towers with external prestressing technology is growing. These steel strands boast remarkable advantages, including superior corrosion resistance and fatigue resistance, enhancing wind resistance and extending the service life of structures.
Leveraging the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have innovatively redesigned our products to simplify the sheath tensile property testing method, thereby enhancing practicability and facilitating sheath performance. Our approach effectively standardizes the quality of the sheath and ensures superior quality and safety for your projects.


Outstanding Product Characteristics

Our unbonded steel strand is meticulously crafted for wind power concrete towers. The thickness of the sheath and the grease can be customized to meet specific technical requirements. The sheath's surface is dense and smooth, with the steel strand's outline visible. Our products meet stringent quality standards, ensuring no air holes, mechanical damage, cracks, or noticeable wrinkles.


Versatile Product Applications

Ideal for Wind Power and Water Conservancy Projects
Perfect for Hydro-power Stations
Integral to the South-North Water Transfer Project
Essential for River Channel and Other Major National Water Conservancy and Hydropower Projects
