Most clubs use steel plate, either vertical or angled, with a sheet of linatex in front to stop shrapnel. Given that clubs come in all shapes - 2/4/6/8 lanes, prone, 3P, etc, etc - the backstops tend to be a custom fit.
You have to remember that a bullet catcher like that is not much use in itself as ranges need "all round" protection. That catcher is fine for accurate shooters, or as a target holder on an open longer distance range, but a novice may well end up shooting the wall around it, which will need protection in and of itself (to protect the fabric of the building), and also anti-ricochet measures.
Most clubs just steel plate the entire target wall, hang a curtain of linatex a couple of inches in front, and put their target framework in front of that.
In some club situations, if you were setting up a range at home, or for hunters to use for zeroing it is ideal.
