I searched around with no luck locally which is to be expected and searched regionally also nothing. The price is king of high, typically 1,000 to 3,000 and up so basically 10x the cost of a regular door. Then I found a bank vault door frame almost in my own back yard. It weighs 360lb and I got it for $35. It's so heavy because it's filled with concrete. The place I got it from says they don't think they have the vault door that goes with it but that they will look for it. If they have the vault door I'm buying it for sure. The opening is only about 30 incest wide but I can cut it in half and expand it out to what ever I want if they don't find the door that matches it. The only thing that sucks about it is this is the only one. The good thing is now that I have one I can copy the basic design. There isn't any point in wasting 1,000 to 3,000 when I can build my own since I can weld, fabricate and mix my own high strength concrete.
