TTU Testing
Actual Texas Tech University cannon that is used to perform the testing of shelter designs.   A 15 lb wood 2”X4” is propelled at 100 mph for horizontal impacts and 67 mph for vertical impacts, in accordance with FEMA 320, “Taking Shelter from the Storm,” 2008 Edition and FEMA 361, “Design and Construction Guidance for Community SafeRooms,” 2008 Edition.

Steel Storm Shelters, LLC has been numerous times to TTU when a new design is implemented. We have had our Above Ground SafeRoom shelters tested and approved, our FEMA 320 SafeDoor for use on our SafeRoom designs or for use in a residential home application. All other shelter doors are also tested to include the Underground, the Mound, and the PorchSafe, doors. We also went for testing for our FEMA 361 SafeDoor for use upon Community Shelters when the FEMA 361 code is required for use.


Vent Block
The Vent Block provides safe ventilation for a storm shelter of concrete or block.  The Vent Block is sized 8”X16. It is built with either a weld stud design to allow it to set in place of a block and be anchored during the concrete back fill process or angle iron frame for anchoring with wedge anchors in to the shelter wall.
Vent Block is made of 3/16 steel plate. It has an expanded metal grid to prevent debris pieces from entering the shelter. It will need the homeowner/contractor to add a screened cover on inside of shelter to protect interior of shelter from small insects.
