Bruno's spiral is a spiral-type fencing made of single- or double-base barbed wire wound around a cylinder of a certain diameter. Coils of barbed wire Bruno's spirals are connected with wire staples, after which it can be used to create fences of a higher degree of protection than the installation of barbed wire linearly, in several rows.
Spiral wire fences of the Bruno Spiral type began to be used a long time ago, back in the days of the First World War, and are still in use today. At present, to create spiral barriers, they began to use not ordinary barbed wire, but reinforced barbed tape, which led to the creation of barriers in a spiral of higher efficiency.
Spiral security barriers Concertina, Egoza, Caiman are manufactured according to the principle of Bruno's Spiral and are the most popular and sought-after barbed-cutting barriers in the creation of anti-personnel barriers. Spiral fences, made according to the Bruno Spiral principle, are currently used to protect the perimeter of not only military facilities, but also to protect private territories, summer cottages, cottages, recreation areas, coastal areas, storage facilities. Bruno's spirals protect the territories of plants, factories, correctional institutions, airport runways, chemical, petrochemical, gas production enterprises, state borders, customs facilities, seaports.
