Product Introduction
Our 1x7 structure unbonded prestressed steel strand, available in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm, is a high-quality steel bar enhanced with anti-corrosion grease and a protective sheath. Specifically designed for water conservancy and hydro-power projects, this product has recently seen increased usage in wind power projects where tower heights reach or exceed 120m. The unbonded prestressed steel strand is becoming the preferred choice for external prestressing technology in concrete towers. Boasting robust corrosion resistance and exceptional fatigue strength, this product enhances wind resistance and extends the service life of structures. It is the reliable choice for your high-stakes projects.
Adhering to the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we've introduced innovative design enhancements that simplify the sheath tensile property testing method. This innovation increases practicability and facilitates optimal sheath performance, effectively standardizing sheath quality and ensuring the utmost safety and reliability of your projects.
Product Characteristics
Our unbonded steel strand is specially crafted for the outer cables of wind power concrete towers. The sheath and grease thickness can be tailored to meet your technical specifications. The sheath’s surface is dense and smooth, visibly outlining the steel strand, and meets strict quality standards—no air holes, mechanical damage, cracks, or noticeable wrinkles.
