Product Description

Product Description

Product Introduction

Discover the cutting-edge 1x7 structure '12.7mm, 15.20mm, 15.70mm, 17.80mm' unbonded prestressed steel strand. This innovative, high-performance steel bar is enhanced with anti-corrosion grease and a durable sheath, specifically designed for demanding applications. It plays a pivotal role in water conservancy and hydro-power projects. As wind power projects soar, with tower heights reaching or surpassing 120m, the demand for concrete towers utilizing external prestressing technology surges. Unbonded prestressed steel strands are at the forefront, offering unparalleled corrosion and fatigue resistance, bolstering wind resistance, and significantly extending the lifespan of structures.
Engineered to meet the rigorous standards of JG/T 161-2016 for Unbonded Prestressed Steel Strand, we have innovatively redefined the design to streamline sheath tensile testing. This advancement enhances practical usability and facilitates the performance of the sheath. It effectively standardizes sheath quality, thereby ensuring superior project safety and reliability.


Product Characteristics

The external cable for wind power concrete towers employs the unbonded steel strand. Tailored to user specifications, the thickness of the sheath and grease is precisely designed and manufactured. A dense, smooth sheath surface reveals the outline of the steel strand. Our stringent quality standards ensure no air holes, mechanical damage, cracks, or noticeable wrinkles, meeting and exceeding all requirements.


Product Application

Ideal for wind power and water conservancy applications.
Hydro-power Station
South-North Water Transfer project
Crucial for river channel and other national key water conservancy and hydropower projects.
