The door on all our models swings to the inside. There is also a peep sight on all of our safe room doors allowing its occupants to see outside and have an idea of what is going on within the vicinity.ĭoes the door swing to the inside or outside? Which is safer? At Survival Zone Safe Rooms we also include a grade 1 lock on our doors so that home and business owners can store valuable possessions inside and then lock them up in order to be secure. The door uses hinge pins and 7/8 sliding lock pins, both made out of cold-rolled steel. In addition, it has three sets of hinge pins and lock pins that are accessible and visible from inside the room. It is reinforced even further by having a 3 structure bracing the door’s backside. Our most popular model, The Tank, has a door made from a 3/8 thick plate steel just like the walls. We use 3/4 Wej-it brand anchor bolts to bolt down and secure our 3/8 plate steel. While most safe room companies weld angle around the bottom of their safe rooms to bolt into, Survival Zone Saferooms bends a lip around the bottoms making it stronger. Can you explain the structure of the safe rooms? This cannon is crucial in testing effective tornado shelters for use in homes and other structures. At the facility, there is a pneumatic cannon capable of firing objects propelled by high wind speeds during a tornado and/or hurricane. The Debris Impact Test Facility is an internationally acclaimed test laboratory for debris impact testing of storm shelters. Our models have been tested at Texas Tech’s Debris Impact Facility.
