It's some good stuff, and requires far less "tensioning" to stretch out over a big-arsed framework. hence, the Frame itself can be lighter as well. However you are limited to the materials gain & texture as far as the usability factor. What you buy is what you use....no painting.
Also for bud, I don't understand how your frame works - how can you expand a rectangular frame and still have square corners?
Bud can clarify things, but essentially each corner is "splined' and can be positioned outward from "flush" by adjusting the shown Threaded rods much the same way as you would use a Turn Buckle tightening system. Only reversed.
Absolutely you'd have to equalize the adjustments so as to create a accurate diagonal dimension, but the whole idea is not to have to make excessive adjustments. You hand pull/staple the fabric as best and as equally as you can, then adjust the Threaded rods only just enough to create a very taunt surface. That would/should be something along a 1/8" to at mos 1/4" adjustment. much more than that and you'd have "Fly apart" issues.
All of that makes for a Screen that is best left in one place...not jostled about...and certainly not repeatedly lifted and lowered into place.
