High security fence is the ultimate security fencing system. The close mesh is used in prisons and other secure facilities as it is virtually impossible to climb. The close mesh also means that the fence is very difficult to cut with anything but power tools. The high security fencing system has been recently developed to make it more secure than ever. The panels are covered by a continuous heavyweight clamp bar, which offers no place for leverage to prise it off. The system also has no removable fixings meaning that panels cannot be removed by would be intruders.
