We'd needed 2 people to cut 16ga steel, 063 alum full width took some weight and oomph.Agree with notareal on the stomp shear. The other pluses with a shear is you do not lose any material and get really nice clean cuts that are ready to use. Depending on the shear you can cut at least .040 aluminum and 3mm ACM no problem, some will cut thicker. The drawbacks are the wider the cut and the thicker the material, the harder it can be. I just about have to jump on the bar when I'm trying to cut 48" wide on thicker stuff.
With a panel saw, and we have one (a Safety Speed Cut), you do lose some of the material. So for example you cannot get exactly two 24" pieces out of a 48" piece... you will get two 23-7/8" or so depending on the blade thickness.
We bought a hydraulic shear a few years ago, it's great for this. My wife can use it with no help which is a plus. It's nice that you can butt 6 24x36 signs together and have it cut down in 2 minutes, it's only 5 cuts. We print .2" crop marks in the corners and 1/4" bullseyes for the holes so no need to measure anything. Round the corners and the crop marks get chopped off.
