Over 400 Tension Bars from Ancon Building Products have been installed on the Forsyth Barr stadium in Dunedin, New Zealand, where England
The steel tension bars are installed in the roof and in the South and West stands of this brand new stadium, to brace the impressive overhead structural steelwork.
The Ancon system includes bars with a special, high strength, rolled thread.
The dimensions of the project are immense. The stadium is almost 50 metres high. The iconic roof is formed from five arched steel trusses, each with a span of 105 metres, and the main steel truss in the South Stand is 130 metres long. The largest Ancon bars were 42mm in diameter and 15 metres in length.
Ancon Tension Systems comprise a range of components, from simple tie bars to complex bracing systems involving several bars joined at one point. Unlike standard tie bars that require turnbuckles, adjustment to the system length is accommodated within the fork connector at each of the bar. Locking nuts firmly lock the bars to the forks and ensure the connection is secure.
