I ended up with a pair of the GRP gratings, 38mm, 1800 long.
After testing the std thickness, the deflection over 1000mm was OK, but I can see potential for fatigue failure. The deflection of the 38mm over 1800mm was less than half of the 30mm @ 1000mm.
My logic is that I'll be doing some stuff solo and so with a pair of winches and these it should really limit potential for being stuck. After common sense of course.
