Product Introduction
Our meticulously engineered 1x7 structure unbonded prestressed steel strands are offered in sizes "12.7mm, 15.20mm, 15.70mm, and 17.80mm". Each is a marvel of prestressed technology, enveloped in anti-corrosion grease and a robust sheath, ensuring superior performance. This innovative product is indispensable for water conservancy and hydro-power projects. With the burgeoning development of wind power projects, where the towering heights of wind power towers now often exceed 120m, the demand for concrete towers using external prestressing technology is soaring. Our unbonded prestressed steel strands offer unparalleled advantages including exceptional rust and fatigue resistance, pivotal for enhancing wind resistance and prolonging the operational lifespan of structures.
In compliance with the JG/T 161-2016 standard for Unbonded Prestressed Steel Strand, our design innovations have significantly refined the test methods for evaluating sheath tensile properties. This breakthrough not only enhances practicality but ensures seamless integration into project applications, optimizing sheath performance and establishing rigorous standards for quality assurance. This pivotal advancement ensures the impeccable quality and safety of your projects.
Product Characteristics
Tailored for the outer cabling of wind power concrete towers, our unbonded steel strands are available in customized sheath and grease thicknesses, meeting user-specific technical mandates. The sheath's surface is flawlessly dense and smooth, allowing the contours of the steel strand to be discernible. Our commitment to quality is manifested in the pristine surface finish that complies rigorously with standards, ensuring it is devoid of air holes, mechanical damage, cracks, or prominent wrinkles.
