Concertina wires are coiled razor wires formed in coils. They are different from barbed wires. Barbed wires are fencing wires with sharp edges spaced out at regular intervals, and are economical options for inexpensive security fences. On the other hand, concertina wire fencing is more sophisticated, rigid and can potentially cause more severe injuries. As a result, concertina wires are used to make razor mesh fencing for high-security purposes, like military bases, prisons and electrical substations.
Because of the welding process, high quality and strength, the price of concertina wires are higher than barbed wires. Precision and skill are required for installation of concertina wires due to the sharp blades present and high tensile nature.
