A cassette roof is a modular and long-life roof structure assembled using steel trusses and cassettes. Only a few parts are needed and thus the roof is quick to assemble. The trusses and cassettes can be assembled on the ground and lifted in place as complete sections.
The maximum width of a cassette roof is 27.1 metres or even wider through special solutions. The height of the roof can be freely chosen. The cassette roof can be opened up if necessary, for example, to enable the lifting of materials.
