Google > GRP grating < and you get a heap of links to check out.
I found years ago a larger sheet should be cut up to give 10 or 12 sets, various thicknesses for use for both recovery or bridging, various patterns from square (say 25 x 25) to larger rectangles (2 x 75 etc so lighter).
I haven't looked for years now, but I found a couple of
places that were ok to sell a larger sheet to the public, pick up or delivered.
My Maxtrax bought on special have been used only on beaches (SA's SE beaches can be treacherous), usually for recovering others, but saved me perhaps 3 or 4 times too.
I have never used them in the deserts, SA Simpson or North Simpson, in general you can back down dunes and take other line, or give it some more momentum to get over anything difficult.
Haven't taken them on the past few desert trips.
Tracks don't work terribly
well in general uphill anyway.
They obviously work in mud such as desert claypans.
