Product Description
9.53mm 12.7mm 15.2mm 7 Wire PC Steel Strand Low Relaxation For Bridge
Product Introduction
Prestressed steel strand is a steel product made by twisting multiple high-strength steel wires. After stress relief treatment, it has extremely high tensile strength and flexibility. It is mainly used for prestressed tensioning of concrete structures to enhance the load-bearing capacity, crack resistance, and durability of the structure.
