Yeah, like Highlandsflyer says, it's referred to as airframe basically, hollow galvanised steel box-sections jigged and welded to a 5mm tolerance in 15m of length, with vertical riba and horizontal support braces. It's basically a pre-fabbed room or two, thrown onto the back of an arctic and send to site, for speedy installation into the building.
Other sections of the factory fabricate RSJ's and other types of skeletal steelwork for buiildings too.
