Hard Steel
This is wire produced by the processes of heat treating soft steel wire rods (KS D 3559), followed by cold processing, followed by the melting of and plating with zinc. The wire is used in heat-treated plated wires (heat conducting wires), wire rods, for farming land, and ACSR steel wires.
