Product Description
ASTM A416 Grade 270 Prestressed Concrete Steel Strand
Available in 9.53mm, 12.7mm, and 15.2mm diameters
Product Introduction
Prestressed steel strand is a high-strength steel cable composed of multiple steel wires twisted together. After stress relief treatment, it is used in prestressed concrete structures to enhance bearing capacity and reduce deformation. With a common tensile strength grade of 1860 MPa, it is primarily used for large-span structures including bridges, buildings, and water conservancy projects.
This product enhances the compressive performance of concrete through prestressing technology and is commonly employed in post-tensioning construction applications.
