Concertina razor wire is intended to erect highly effective physical barriers and is used either as temporary (mobile) barrier or a fixed one installed onto the ground or to the fence.

Concertina razor wire produced by OCEAN is a durable and effective barrier for perimeter protection of various units.

We are the leading producer of concertina razor wire in Russia and manufactures it according to the standards of Russian Ministry of Defense and Ministry of Internal Affairs, by which Concertina product is certified and recommended for usage.

All materials used in the process of the concertina razor wire production (core wire (2.5 mm in diameter) and barbed tape) are made of hot dipped galvanized steel that is why razor wire is fully corrosion resistant.

Concertina razor wire is a spiral, coiled up from the reinforced barbed tape. The adjoining loops of the spiral are connected in the particular way with each other which makes concertina wire spatial and almost insuperable.
For the loop connection we use hot dipped galvanized clips or annealed galvanized wire. Either way is available by the customer’s request.
