Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is a high-performance, specialized steel bar, meticulously coated with anti-corrosion grease and encased in a protective sheath. Primarily utilized in water conservancy and hydro-power projects, this product is increasingly essential for wind power projects, especially with tower heights reaching or exceeding 120m. The innovative use of unbonded prestressed steel strands in concrete towers employing external prestressing technology offers unparalleled corrosion resistance and fatigue strength, significantly enhancing wind resistance and extending the structural lifespan.
Adhering to the JG/T 161-2016 standard for Unbonded Prestressed Steel Strand, we have revolutionized our design to streamline the testing methods for sheath tensile properties, thereby enhancing practical application and user convenience. Through these innovations, we have optimized sheath performance, rigorously standardized sheath quality, and significantly bolstered project safety and reliability.


Product Characteristics

For wind power concrete towers, the unbonded steel strand's outer cable features a sheath and grease layer customizable to the user's technical specifications. The sheath's surface is uniformly dense and smooth, clearly outlining the steel strand beneath. Our stringent quality criteria ensure the sheath surface is free from air holes, mechanical damage, cracks, and prominent wrinkles.
