Product Description

Product Description

Product Introduction

The 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is a premium, specially designed prestressed steel bar, fortified with anti-corrosion grease and a robust sheath. Ideal for water conservancy and hydro-power projects, this product has seen a surge in usage for wind power projects, where tower construction heights now often reach or exceed 120m. Increasingly, concrete towers utilizing external prestressing technology are opting for this innovative unbonded prestressed steel strand. Its standout features include exceptional corrosion resistance and remarkable fatigue resistance, significantly enhancing wind resistance and extending the structure's service life.
Adhering to the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have pioneered a design that simplifies the sheath tensile property testing method, enhancing practical application while making the process more user-friendly. Our advancements in sheath performance not only standardize quality but also bolster project safety by effectively improving the overall quality of the sheath.


Product Characteristics

For the outer cables of wind power concrete towers, our unbonded steel strand is the go-to choice. Customizable sheath and grease thicknesses can be tailored to meet specific technical requirements. The sheath's surface is dense and smooth, clearly revealing the steel strand's outline. Our quality assurance ensures no air holes, mechanical damage, cracks, or noticeable wrinkles, meeting all stringent surface standards.


Product Application

Wind Power, Water Conservancy
Hydro-power Station
South-North Water Transfer Project
Major River Channels and other pivotal national water conservancy and hydropower projects
