Built to protect your family in the strongest storms on Earth. Independently tested beyond any required standard — because your family deserves certainty, not doubt.
Although EF4 and EF5 tornadoes account for 2% or less of all tornadoes, these powerful storms cause a disproportionate amount of injury and catastrophic damage. When the stakes are this high, you should never have to wonder if your storm shelter is strong enough.

FEMA EF5-Rated and ICC-500 Certified Tornado Shelters
FEMA EF5 Rated ICC-500 Certified ATSA Certified NWI Tested — Texas Tech University Made in the U.S.A.
Every above-ground tornado shelter we design is independently tested by Texas Tech University’s National Wind Institute (NWI) to ensure the strength of our designs and strict compliance with FEMA standards. During these rigorous NWI tests, our shelters are subjected to 250 mph wind speeds to simulate the extreme conditions of an EF5 tornado, and then struck by 15-lb wooden planks traveling at 100 mph to simulate lethal debris impacts.
Going Beyond the Standard: Brutal Real-World Testing
While NWI testing is an excellent baseline, it cannot fully predict how a shelter will perform if a house or tree collapses on top of it, or if it is struck by heavy, high-speed debris carried by an EF5 tornado. To answer these critical questions, our team developed a series of extreme tests to push our shelters to their absolute limits.

Watch: Extreme Shelter Testing
Side-by-Side Competitor Testing: The Direct Hit
After our shelter survived these extreme scenarios, we went further. Our team welded a 4,500-lb solid steel cart — designed not to crumble like a standard motor vehicle — and purchased shelters from different companies to see how they would withstand a direct hit. Although all competitor shelters were FEMA EF5-rated, only our shelter survived the impact and remained firmly connected to the concrete.
Watch: The Valley Difference
Are Above-Ground Tornado Shelters Truly Safe?
We hear this question every week. The answer is: Yes — but it depends entirely on who builds it and how it is constructed.
During a tornado warning, the most common recommendation is to seek shelter underground in a basement or crawl space. While these are excellent options, many homes do not have access to them. If you do not have a basement, a properly manufactured and correctly installed above-ground shelter is absolutely safe during an EF5 tornado.
8 Vital Features to Look for in an Above-Ground Shelter
1
Integrated Steel Floor: Your shelter must have a solid steel floor — not just walls anchored to concrete.
2
Fully Welded Construction: The shelter must be welded, not bolted together. Bolts create structural weak points under extreme stress.
3
Reinforced Corners and Walls: Prevents crushing and denting from heavy, high-speed collisions.
4
Heavy-Duty Concrete Anchors: Anchors must be secured deep into the concrete slab — durable, wide, and no less than 4 inches long.
5
Inward-Opening Doors: Ensures you cannot be trapped inside by debris blocking an outward-swinging door.
6
Proper Ventilation: At least two vents to ensure adequate airflow for all occupants.
7
Thick, Dense Steel: Made of real, heavy-duty steel. The heavier the shelter, the better the protection.
8
Interior Steel Barricade Pins: Do not rely solely on deadbolts or electronic keypad locks, which can fail during a storm.

Your Family Deserves Certainty — Not Doubt
EF4 and EF5 tornadoes are catastrophic events, and the stakes could not be higher. Our above-ground shelters are the strongest you will find on the market. We stand behind them 100% because of the meticulous engineering and brutal testing we put into every design.
Have questions about above-ground tornado shelters? We have answered the most common ones below. If you don’t find what you’re looking for, contact our team directly.
Yes. While underground shelters (like basements) are often recommended, a properly engineered above-ground shelter is absolutely safe during an EF5 tornado. To ensure maximum safety, an above-ground shelter must be fully welded, constructed from heavy-duty steel, and anchored deeply into a concrete slab using heavy-duty wedge anchors. Our shelters are FEMA EF5-rated and have survived extreme debris impact testing, proving they can withstand 250+ mph winds and direct hits.
Bolted shelters are assembled using nuts and bolts, which can become weak points during the extreme stress and vibration of a tornado. Welded shelters, like ours, are constructed as a solid, continuous 6-sided cube. A fully welded design offers vastly superior structural integrity and prevents the shelter from buckling or failing under heavy impact.
A solid steel floor serves two critical purposes. First, it significantly increases the overall structural strength of the shelter, preventing the walls from twisting or separating. Second, a continuous steel floor allows the shelter to act as a Faraday cage, which can protect occupants from electrocution if live power lines fall onto the shelter or the surrounding area.
Our shelters are secured using heavy-duty concrete wedge anchors that are driven deep into the concrete slab. We use durable, wide anchors that are no less than 4 inches long. This deep anchoring system essentially combines the massive weight and strength of the concrete foundation with the steel shelter, ensuring it cannot be lifted or disconnected by EF5 tornadic winds.
This is a common concern, which is why all of our tornado shelters are designed with inward-opening doors. If heavy debris — such as a collapsed roof or fallen tree — lands against the outside of the shelter, an outward-swinging door would trap you inside. An inward-opening door ensures you can safely exit the shelter once the storm has passed.
Proper installation is just as critical as the manufacturing of the shelter itself. We directly install every shelter within a 100-mile radius of our showrooms using our own team of expert installers. For customers outside this radius across the U.S., we offer drop-shipping options and provide detailed specifications to ensure your local contractor can anchor it correctly to FEMA standards.
Adequate airflow is vital when sheltering during a storm. Every shelter we build comes standard with three or more strategically placed ventilation ports to ensure proper airflow for all occupants, even if one vent becomes obstructed by debris.
Yes. Every shelter we manufacture is FEMA EF5-rated, ICC-500 rated, and certified by the American Tornado Shelter Association (ATSA). Furthermore, our designs are independently tested by Texas Tech University’s National Wind Institute (NWI) to verify they meet and exceed these stringent national safety standards.
