If the stuff Salty has isn't what you are looking for you can call local steel shops and ask for expanded metal. I would weld a band around the edges because open ends on this stuff catch everything; pants,shoelaces....
What MAC said is correct. We used 3# expanded steel for making raised floors. We welded 3/16" x 2" flat bar around the perimeter. You could also use angle around the perimeter. You can get expanded metal in aluminum.
When we had our shop in Cambridge we bought it from Turner Steel in West Bridgewater. Unfortunately the owner moved our fab shop to Canada.
