While VCEs are typically the focus when designing blast resistant buildings, some over pressures occur due to the catastrophic failure of pressure vessels. It is important to provide building occupants a level of protection against flying objects. The FORTRESS Protective Buildings, LLC modular reinforced concrete building is equivalent to being protected from a ¾" solid steel plate!

Check out our recent tests showing the impact of a 2.2 lb fragment impacting the 3/16-inch corrugated steel plate (376 ft/s velocity) compared to the 8-inch Reinforced Concrete FORTRESS panel (378 ft/s velocity).
