Wire rod generally contains a diameter of 5.2 – 42mm there are different types of shapes such as round, square, semicircular, and hexagonal. The main factor that determines the technical parameters is what material the wire is made of. Wire rod is made by drawing wire through hot metal shafts. The shafts form the metal into long strands of metal by compressing the sides from different angles, while this method is called hot drawing the metal is not preheated it is just heated as it goes through each of the shafts to form the metal. It is then rolled on to a spool to be cooled further, it can be cooled by the air or cooled using specialized fans.
