358 warehouse security fence

High security fence is a type of barrier that is designed to prevent unauthorized access to a particular area. They are often made from heavy-duty materials such as steel or reinforced concrete and may include additional security features such as barbed wire, electric currents, or motion sensors. 

High security fence is typically used to protect sensitive areas such as military bases, prisons, and private properties. The height of these fences is usually much greater than standard fences to deter climbing, and they may also be buried underground to prevent tunneling.
