The most common is 1/2" not 1/4". I think what makes the egg crate still work at 1/2" is it has some depth to it, so unless a fish is jumping perfectly straight up through a particular square it usually gets hindered enough that it doesn't make it through.
That screen in the pics I posted is almost a year old, and I've never cleaned it. No salt creep here.
If you go egg crate, have someone put it on and off while you stand back and see if you're ok with the amount of light blockage. I don't know if it's because of the height of my fixture, or if it's the LED's, or what, but it's a significant drop in light on my tank.
