A net barrier, sometimes called a vehicle arrestor, is an active, rather than passive, type of vehicle barrier that often prevents penetration using a deployable reinforced net. The net in essence absorbs the kinetic energy of a hostile vehicle rather than abruptly terminating it and by doing so causes catastrophic damage the way a wedge barrier or bollard works.
As a result of the net’s “give”, damage to the vehicle is mitigated and is often less lethal to the occupants. For this reason, net barriers are often referred to as “reduced risk” barriers. In addition, net barriers are typically deployed from a housing channel below the roadway. When not in use, this allows for unobstructed traffic flow, much like retractable bollards provide. The net and its component parts are, more often than not, completely re-useable which saves on maintenance costs.
Some net barriers, like Barrier 1’s VA-NET-300 or the Global Grab 400 can be deployed in as little as 2 seconds.
This means the net barrier stops a vehicle traveling in either direction, making it ideal for entrances to military bases and security checkpoints, private facility entrances and restricted roadways.
Many net barriers are on the Protogetic's new searchable DoD Anti-Ram Vehicle Barrier List. It is the exact same approved list but designed with features that allow architects and engineers to more easily search categories and products while instantly being able to download detailed product information and testing certifications. You can also find non-DoD list, anti-ram rated net barriers instantly at Protogetic.com using our proprietary filter that saves hours of searching. You can even perform side-by-side comparisons of net barriers and other high security products like blast resistant doors and ballistic resistant windows.
