A razor wire fence is a type of high - security fencing system. It is mainly made of steel wires with sharp blades attached. The blades are usually arranged in a spiral or barbed pattern, which can effectively prevent people and animals from approaching or crossing. Due to its excellent deterrent effect, it is widely used in places that require high - level security, such as prisons, military bases, border areas, and industrial and mining enterprises. It can also be combined with other fences to enhance the overall security performance. The installation of a razor wire fence is relatively simple, and it has the advantages of being durable, rust - resistant, and easy to maintain. However, because of its sharp blades, it also poses a certain safety hazard, so it needs to be used and maintained with caution.
