Visitor Safety & Control are essential to the success of any event. There will be areas which you don't want vistors to go into and routes around an event that will help you manage vistor access. Systems that help with this include Post and Rope and Rectractable Queuing Barriers.
Often it is necessary to define an area which is reserved for customers and visitors. This include open-air cafes and restaurants, which would benefit from a Cafe Barrier to define the area and carry advertising on the outside for passers-by.
Similarily, we have an indoor telecopic systems, like Aero Roller Banners, where you can create a Linking Screen System with roller cassette banners for graphics displays. This can include taller sections for more important graphics.
These are not short-term investments - they are likely to be important for some while and may be required as a matter of course as our economic and social interaction develops in time.
