Re: Oxy Fuel Cutting
Of course it's always better to be safe than sorry. In a nice new shop like that, the sand is an excellent idea. Not because the molten steel will hurt the concrete, but because as soon as it hits, all that heat is instantly transferred into the floor, and the metal actually breaks into a buncha little beads and goes sliding around. Kinda like when you were a kid and busted open a mercury thermometer and poured it on the floor, only little hot pieces instead. Very easy to inadvertently step on one, and you won't know it until you smell your socks smokin'. Plus, it's a harder cleanup if nothing like sand is there soakin' it up (you'll find beads spread all over). I'm just sayin' whatever the melting point of concrete is, probably only molten lava or a nuclear weapon would hurt it. Sawhorses...angle iron..whatever you want to use to get it up off the floor for a clean cut. beaterchevy is right though....get too close to the floor, and the torch itself will you leave you a nice little black spot.
If you don't care about the environment like me, do what I do....cut outside and send it all back to mother nature.
