It is fair to say that for most fans of Leeds United, items like box profile roofing sheets will not have been on their minds much during what has been a very exciting few weeks. But they are among the many components of a big project now in the works.
As well as winning promotion to the Premier League, the club has unveiled plans to expand Elland Road from its current capacity of just under 38,000 to 53,000. The latest step has been a public consultation with fans and local residents over the scheme, ahead of the submission of a planning application.
The plans will see both the North and West stands expanded, with images of the design indicating new roofs will be required, with modern materials and cantilevered construction that will mean no obstructed views for spectators.
This is a far cry from the older roofs still present at some venues, where posts holding up the roof can often block the view. One element that makes cantilevered roofs possible is the use of lighter materials, such as sheet metal.
Other elements of the roof design will be the incorporation of photovoltaic panels to enable some of the electricity needed to power the venue to be generated on-site.
The new roofs will be held up by large crossbar-type structures, without a continuous roof at the same level sweeping around the stadium. This is the kind of structure that enables strands of different designs to be combined as a venue is progressively modernised, rather than a new one being built from scratch.
Although all this requires planning permission, the Elland Road project has become more likely with the recent confirmation of £2.1 billion in government funding for another major construction project in Leeds, the long-awaited mass transport system.
This will enable the establishment of a line through south Leeds that will serve the stadium, helping address concerns over access and parking in the vicinity raised by the prospect of larger match day crowds.
