1×7 galvanized steel strand is a high-strength metal product manufactured by twisting one central steel wire with six outer steel wires. Available in 8-12mm diameters, this load-bearing material is widely used in engineering applications requiring exceptional tensile strength and corrosion resistance. The product primarily conforms to YB/T5004-2012 standard, with some variants also meeting international standards such as ASTM A475.
