Aluminium crowd control barrier is to provide protection for important areas and locations. It can be used to prevent a large number of people or spectators from entering the range that is not allowed, or to resist the surging of potentially dangerous crowds, to prevent the danger caused by the flow of people, and achieve the effect of safety protection.

During performances, the audience always likes to crowd the stage, especially the safety of the actors is very dangerous, and it is very difficult to rely on personnel to maintain order. This audience isolation barrier can effectively isolate the audience from the stage and the outside world from the performance site to reduce accidents.
