Underground Garage/Carport Flush Shelters

At SteelSafe Shelters, our mission is simple, “We Save Lives!” Notably, this model is by far our best seller and the shelter most homeowners want. Another key point is these shelters must be installed under a roof, typically inside a garage, carport, shed, barn, etc. We are a true American-Made company that develops all of our products in Chattanooga, Tennessee.

All of our shelter models and styles have been tested to meet or exceed FEMA 320/361 and ICC-500 criteria through the Wind and Debris Laboratory at Texas Tech University.

A safe room is a hardened structure specifically designed to meet the Federal Emergency Management Agency (FEMA) criteria and provide near-absolute protection in extreme weather events, including tornadoes and hurricanes.

Near-absolute protection means that, based on our current knowledge of tornadoes and hurricanes, the occupants of a safe room built in accordance with FEMA guidance will have a very high probability of being protected from injury or death.

Installs in garage/carport floor, directly under your vehicle, taking no usable space from your garage and can be installed to allow quick access without the need to move the vehicle.
