I was working on a large building today, I guess it was built in the 1980's and it had a flat roof, the roof frame was RSJ's covered with corrugated sheets, which had 6 inches of Polystyrene on then ply, felt, tar etc.
The corrugated sheets had a profile about 4 inches deep and 2 inches wide and was flat on the top and bottom
nunununu
It was only about 1.2mm thick and from the RSJ spacing seemed capable of carry enormous loads.
Any idea what it's called, would be perfect for a future project of mine.
I have googled but all I get is box profile sheets.
