Barbed Wire With Sharp Edge on Various Fences for High Security Barrier

Barbed wire, also known as bob wire, is the most important component of barbed wire fence system. It can be used individually to form the barbed wire fence, and it also can be attached onto various fences, such as chain link fence, welded wire mesh fence, expanded mesh fence or palisade fence for high level security barrier. They are widely used for prison fencing, airport fencing, farm fencing, ranch fencing, residence fencing, large construction site fencing and so on.
