The ceiling system has been designed as an integral framework for use in big-scale B2B events. The construction based on a modular aluminium profile system allows different ceiling heights. Its variable within a 6m span length leading to unlimited length and width. Small cross sectional areas and low weight minimize the transport costs by 35%. It reaches a high grade of mobility due to a tool-less mounting, reducing the effort for installation by 50%. The system is used as a multifunctional beam: lighting or relocatable wall systems can be inserted without tools. Electrified beams are ready to use, since all installations are factory made.
