 Gauge steel is used:
The floor is 10ga, main unit 12ga, and door 14. All sizes have channel/angle iron reinforcements added. Across sides, floor, roof, and back. Extremely heavy duty built. Latches, three,  are 1/2" spring loaded,  and Three Heavy Duty  hinges.
The door has not been wind tested because it doesn't really pertain to us, Ours are flat, not like saferooms. Plus we feel, shooting a 15lb. 2x4 at 100mph is not a true test. Tornados throw whole trees, cars, tractors, and other people's houses at you. If your not completely under the normal surface level, you are a target.  YOU HAVE TO BE COMPLETELY BELOW THE NORMAL SURFACE LEVEL  TO SURVIVE A LARGE TORNADO.

Stairwell
They are off-set, no room taken from your shelter.  They have eight steps, just slightly steeper than regular stairs in a house. They all come with traction tape that contains two strips, a reflective yellow and a glow in the dark.
Standard with one handrail, an extra is no charge.

Measurements:
The door is 32" x 57".  Standard height in center dome is 6'5".  Top of dome to door lip is 6" to 8". Can be extended. Seat width 10", can be extended. Turban vent 14", can be altered.  All shelters can be made to go deeper in the ground, up to 18" at the center dome.

Coatings
The outside is coated with five gallons of Epoxy, from Sherwin Williams, Called "cold tar epoxy"  Same as used and approved by the U.S. Corps of Engineers for use on salt water drilling rigs, underground gas storage tanks and even dam gates! It's  a very hi-mil coating  that we spray on with a hydraulic pump spray rig. Top, bottom, everywhere! . Inside is first primed with Bullseye123. Then top coated with Sher-Kem  gloss white. A direct to metal chemical/paint from Sherwin Williams.

We don't skimp on materials like some. We use ALLOT of steel support, Check their pictures vs Ours! On our 12' we  use four vertical 4" X 1/4" channel irons, five under the floor, two on the roof, one on the rear. Built like a tank!
