Scandinavium Arena, Gothenbrug Sweden

As one of the busiest, largest indoor arenas in Scandinavia, Gothenburg Scandinavium Arena often needs to change their flooring surfaces to cater for the next activity, ranging from ice hockey to rock concerts. For handball matches, Junckers’ A4 Portable Sports Floor is installed on top of the ice and in a matter of hours, the arena boasts a floor with the same qualities as a permanent sports flooring system.
