Product Description

Galvanized Steel Strand

This product is tightly twisted and evenly twisted, the galvanized layer is smooth and firm, and has strong corrosion resistance. The vertical hot-dip galvanizing process is used to ensure the thickness of the zinc layer. As the core skeleton material of power cables, it directly serves the construction of power supply and power grid and its transformation and renewal. It has the advantages of corrosion resistance, high strength, good ductility, and high cost performance. Products are widely used in hangers, suspensions, communication wires, overhead power lines, cable steel cores, and tethering of fixed objects.
