7-Bar Ammunition and HAS Explosion Test (610x355)
Successfully tested by the U.S. military, meeting the highest explosion-resistance standards of NATO and the U.S. Department of Defense.
Tornado Missile Impact Test
The only arched building system to successfully pass tests conducted at Texas Tech University.
Napalm Test
Demonstrated structural stability even under extreme fire conditions.
