In2Structures | MDR20 Roof

MDR20 Roof

Very popular with the live events industry, this 20m wide roof is used annually on the Starlight Classics event in Johannesburg and Cape Town and has also been used to Launch "€œVodacom is Red"€ in Orlando Stadium as well as the Springbok return after winning the World Cup in 2007.

  • The steel structure of the MDR20 has been designed to carry a load of 2500Kgs UDL per arch. The skins have been offset from the main structure so that ample climbing space is available for rigging. Skins are black on the inside, enabling the structure to host day events with complete black-out.
  • The MDR20 Cantilever is an optional addition to the standard MDR20 structure to extend the roof coverage.
