How Barbed Wire is Made

The creation of barbed wire is a fascinating process and fencing manufacturers can create it easily with the use of a barbed wire machine from Bergandi. Below is a brief explanation as to how this high-security fencing is made.

The first step in manufacturing barbed wire is to make the steel ingots and billets, which are necessary pieces into holding your wire together. The ingots are heated and pushed through grooved rolls, which form the billets at the desired size. These billets are then heated and moved through rollers to create wire rods, which are then lubricated and pulled through dies to reduce the diameter. Since the wire initially comes out very stiff, it needs to go through a process called annealing. Annealing is performed by heating the wire in molten salt, lead, or a nitrogen furnace and this will make the wire more pliable.

The wire is then galvanized, which preps it to be threaded through a barbed wire machine to transform it into the desired security fencing material. Two wires are simultaneously fed into the machine, which twists them together into a cable. A separate wire is then inserted from the side and the machine twists it around the cable, cutting it at an angle to form the barbs.
