All Steel Underground Bunkers – Bomb Shelter – Custom Engineering

DEFCON Underground MFG constructs its all steel underground bunkers and bomb shelters from a set of stamped Custom Engineering plans. These plans are designed by a professional structural engineer. All of our underground bunkers and bomb shelters are made 100% out of steel inside and out. DEFCON Underground MFG underground bunkers and bomb shelters can also be covered with steel reinforced concrete. This will give our bomb shelters an actual nuclear blast rating. A lot of companies say there shelters are bomb shelters but are not actual designed for it. True bomb shelters must be able to carry a significant blast load pressure. Bomb shelters must also be buried at a correct depth to withstand radiation. The depth of the bunker will depend on the range of the anticipated nuclear attack. Please take a look at our engineering load letter. DEFCON Underground MFG makes sure everything is over engineered and we cut no corners. We can also custom engineer any floor plan that you are looking for. If you are looking for escape tunnels, hidden doors, special defensive options,  Rest assured that when the time comes to use your underground bunker or bomb shelter you will have no worries.
