A Safe Sheds above ground storm shelter isn't just poured concrete. There's steel rebar reinforcement throughout the shelter to ensure life-saving strength. As you can see in the photos above, an entire rebar cage is constructed before the interior concrete forms are put in place. And a rebar grid will also be attached to the wall grid rebar and assembled for the roof of the shelter.
This design meets FEMA 320 and 361 standards for safe rooms that provide near-perfect protection in the face of EF5 tornadoes and Cat 4 hurricanes.
