The band is touring South Africa as part of its 360 Degrees Tour that was launched in 2009.
After the Sunday gig at FNB Stadium in Johannesburg the 22-time Grammy Award-winning band will move to Cape Town to perform on February 18.
Tickets went on sale in October and by yesterday 101,000 had been snapped up. The stage will allow all fans at the 11,0000-seater stadium to have a clear view of the group.
The stage, designed by Willie Williams, who has worked on 10 productions with the band, was built by Belgian company Stageco. It is 24,7metres high and can support up to 180tons.
The steel stage also includes a cylindrical video screen, that weighs 54 tonnes.
Launched in support of the group’s 2009 album, No Line on the Horizon, the tour won the Billboard Touring Award for highest grossing tour in 2009 and last year.
The group, which is led by Bono, was formed in Dublin (Ireland) in 1976 and has sold more than 150 million records.
