What is the thickness of a GFRC wall panel?

Each wall panel is 6" thick, consisting of a 3" tubular steel frame and 3" of GFRC and concrete face mix. This 6" wall thickness should be considered when calculating the inside dimensions of a shelter.

Are GFRC Shelters buildings bullet resistant?

Yes. Our standard wall design has been tested, and is proven to be resistant to a variety of firearms and rounds at a distance of 20 feet. It is interesting to note that one of the first users of glass fiber reinforced concrete was the U.S. Military. One of the unique properties of this material is it’s ability to accept multiple rounds at close distances without penetration.

Can GFRC Shelters manufacture an expandable building?

Yes. In fact, the steel frame provides a tremendous amount of flexibility in terms of future expansion. For example, with the proper roof reinforcement, any wall can be removed for expansion. In addition, wall penetrations are possible anywhere in a wall as long as they are 3" or more from the edge. This means cable entries, HVAC openings, even doors, can be added prior to delivery, or in the field.

What is the maximum interior height of a GFRC shelter?

Interior height is limited only by the ability to deliver the building to site. The floor and roof of each GFRC shelter is 7" thick. To achieve an interior height of 9’, the exterior height must be 10’4". GFRC routinely manufactures shelters with an interior height of 12'.

What is considered a "wide load"?

A wide load is any building width greater than 11’6".

In what states are GFRC Shelters currently approved or certified?

GFRC has delivered shelters to every state in the U.S.
