"Mini Orb" (mini corrugated iron).......uses?

What are people's thoughts on using Mini Orb (the local term for small scale corrugated iron) such as seen here............ http://www.bluescopesteel.com.au/index. ... 10BC6BF4E7 ...............for diffusion panels? 8)

I've got the same question! I've seen similar acrylic or plastic sheeting that is meant to be used as roofing for sheds or carport type structures. These panels are somewhat flexible - so I envisioned them fastened to a wall panel at the edges and bowing out in the middle to form convex arcs along the sides of a room. It's Relatively cheap and comes in many colors including clear & tinted. Would be an inexpensive and "space-age" looking fix if they were usable. ... per usual, I have absolutely no physics or test #s to back this up. Here's a link to something similar: http://www.kemlite.com/sequentia_corrugated/poly300.cfm

I've seen something similar used. But the ones I saw were (as often) lightweight and become a panel absorber in itself with a clear resonance range. Such kind of diffusers should be stable. For labs as rule of thumb a minimum of 5 kg/m2 is described (better more). I know a lot of diffusers will not comply with this rule of thumb, but I also believe a lot of commercial related stuff will show side-effects not described by the seller. And it also depends on shape and so on.
