Thank you all for this excellent discussion about safes. I just got off the internet reading about fireproof or resistant commercial tile, fire brick, and concrete. Someone should start a safe business, manufacturing a safe made of steel with the door attached and also an interior of steel attached with holes in the top to pump in concrete, you deliver the safe to the customers house, basement installation only and on site fill the interior of the safe between the two steel shells with concrete pumping it in under pressure on site. The concrete would have to be a special formulation so hard to resist all drilling and cutting and the safe after the concrete was pumped in nobody could move it because it was so heavy so if you moved you would have to sell the safe with the house, should help with fireproofing too. From what I read about commercial outside fireproof tile probably 1/2 to inch thick, I should buy a tile saw, and tile the outside and inside of my safe. What do you guys think about those ideas, crazy or not?
