Product Introduction
Discover the exceptional 1x7 structure unbonded prestressed steel strand, available in sizes 12.7mm, 15.20mm, 15.70mm, and 17.80mm, designed with anti-corrosion grease and a durable sheath. This specialized prestressed steel bar is crafted to excel in water conservancy and hydro-power projects. With the rise of wind power projects and the towering heights of wind power towers often reaching or exceeding 120m, the demand for unbonded prestressed steel strands is growing. Our product is the choice for concrete towers utilizing external prestressing technology, offering unmatched advantages such as superior corrosion and fatigue resistance, enhancing wind resistance, and significantly prolonging service life.
Pioneering innovation inspired by the JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we have revolutionized the design to streamline the testing methods for sheath tensile properties. This transformation enhances practical usability, ensuring excellence in sheath performance, effectively setting new benchmarks for sheath quality standardization, and elevating project safety and quality assurance.
Product Characteristics
The outer cable of wind power concrete towers utilizes our unbonded steel strand, with sheath and grease thickness tailored to meet specific technical user requirements. The sheath’s surface is dense, smooth, and allows the steel strand’s outline to be visible. Our expertly crafted surface quality ensures no air holes, mechanical damage, cracks, or noticeable wrinkles, meeting stringent quality expectations.
