Security Barriers

Security barriers are designed to keep out and deny unauthorised persons access to facilities, equipment, and resources.
 
Companies who deal in security barriers therefore offer solutions with the above stated goals in mind. Nevertheless, security barriers have to be designed according to strict specifications. Hence, security barriers used for pedestrian control could be inadequate for motor vehicles. Pedestrian security barriers normally consist of retractable gates or security portal doors. Security barriers for motor vehicles are varied. They can consist of manual or automated boom gates. These gates are usually manned by security guards who check credentials before giving permission to enter. There are also the ground retractable security barriers, as well as traffic bollards which are used to control traffic.   
 
One can also find electro–mechanical barrier systems which are cost efficient and controls vehicle entry and exit. They are normally found at shopping centres, airports, and other such places. Hydraulic drop arm barriers are highly effective as security barriers as they can stop a vehicle travelling at eighty kilometres per hour, weighing up to 8000 kilograms. Pre-cast security barriers on the other hand, are normally used in commercial or residential areas. They range from one to three metres in height and are capable of being very strong. There is also the traditional window bar and steel gates used as security barriers in homes and offices. These barriers come in varying styles and strength.
 
Other barriers are much more specialised like hi-tech port and harbour security barriers.
