Barbed wire is an old fence type and is generally used to determine the surroundings of an area. While it was previously pulled with the help of wooden poles, it has recently started to be used with concrete poles and is also called concrete pole fence. Barbed wire is generally widely used to determine the boundaries of open land areas when checked. If you are wondering what barbed wire is, we can also express it as follows. It is a type of wire that is similar to cable in production but is not covered with plastic or different conductive materials on its outer surface. Barbed wire is formed by wrapping and strengthening two separate flat wires with the twisting method. It is called barbed wire because of the sharp protrusions formed as a result of additional wire being wrapped on the double wire at certain intervals and bent. If you pay attention, barbed wire is also used in the defense industry and in determining the boundaries of certain land pieces. In general, barbed wire usage areas are mass housing, military facilities, industrial facilities, refineries, country borders, natural gas pipelines, energy centers, factories, prisons and fields.
