Road Blocker Barriers are designed for controlled passage in all institutions, businesses, plazas, embassies, security and military units with high security requirements; assassination and sabotage prevention road barriers. Road blockers, whose resistance to high speed and severe impacts have been tested with all parts used in the design and manufacture of road blockers, are produced in desired dimensions according to demand. They are modern "RAMP BARRIERS" manufactured to stop unwanted traffic flow in places such as government institutions, congress palaces, private meeting rooms, airports, where other traditional barriers do not provide a deterrent effect.
