The compression ring sits at the back of the four stands and creates an elliptically-shaped ring, which will hold the cable net roof structure. After the cables have been lifted into position the roof will be covered with 287 glass roof sections and 810 cassettes.

Supporters who regularly watch our live stadium webcams will be aware of the flying columns that are currently positioned in the stands across the stadium site.
These columns will form the inner part of the roof and are connected to an upper and a lower tension ring in the centre of the roof.
