On almost any day, at any time, you can turn on the news and see a startling headline. Terror attacks and natural disasters have become a common occurrence. In locations and events where we used to feel safe, we now feel unsure and possibly unprepared. The time has come to be prepared. Plan for the unknown and unseen and check out our Underground bomb shelters for sale.

DEFCON Underground Mfg., has a wealth of manufacturing experience and holds several welding certifications. We have manufactured a wide array of stainless steel objects, including underground bunkers, gantries, aerial walkways, gasifiers, damn components, and high end handrails. Our steel structures can be found at some of the major landmark buildings in our hometown.  Our knowledge and emergency shelter experience ensures that your underground bunker will be air and water tight regardless of the outside climate. 


DEFCON Underground Bunker Bunks

DEFCON Underground Mfg, crafts underground bunkers, bomb shelters and emergency shelters that are built with high quality plate steel and re-enforced structural metals. Your entire underground bomb shelter, with renowned durability, is extremely rigid and strong, unlike shelters from many of our competitors.  As extreme pressures are applied; the steel construction frame used in our engineering adds tremendous strength to the bunker while distributing weight and pressure across the entire are. We build them without structural “weak spots” and these underground bunkers will not collapse under weight or unexpected shifts in the surrounding areas.
