Just looked it up. They're based there. Whether all the material will come from there isn't clear actually...

Severfield at Dalton mostly produce beam & column work (H & I shapes), whereas most of the steelwork you see in stadia is in the roof in the form of tubular steel.
Severfield fabricate mostly at Bolton (was called watsons and is directly across the road from BWFC)
The company I work for has supplied them with steel for football stadiums at Bolton, Charlton, Middlesbrough, Celtic, Hull, Barnsley, Man Utd, Man City, Arsenal & also the Olympic stadium - amongst others.
There are other steel fabricators in the UK and Europe, but none in the UK are anything like the size of Severfield - if they want the work they generally get the job (exceptions being the millennium stadium in cardiff and new wembley stadium).
They also did the steel work for the Shard in London plus other high profile prestigious jobs (twickenham, murrayfield, lords cricket, epson racecourse grandstand etc etc etc) if you look at their website you will see they do excellent work and I'm sure THFC will get a fantastic result.
We also supplied material for the millennium stadium in Cardiff and a lot of stadia in Portugal for when thier Euro finals, but that was all .ated in Europe.
Before anyone asks - no there's absolutely nothing being asked for us, but it's early days.
