Innovative Patented Security Features
ProSteel Door Security Features
FEMA 320 Compliant
ProSteel's FEMA 320 steel doors are designed to withstand tornado force winds and to resist missile penetration by flying debris in order to protect occupants from injury.
Our security doors, tornado doors and vault doors were tested using a 15-pound, 2x4 inch wood board traveling horizontally at 100-mph and impacted by three "missiles" in different and vulnerable locations.
Round Locking Bolts
The Locking Bolts are round hardened steel bars that move behind the door frame to hold the door locked and closed. Bigger bolts and more of them, provide greater security.
Duo Formed Door
Our Duo Formed Doors are made from multiple layers of steel, carefully joined together, to provide superior strength, security and protection.
UL Listed Type 1 Lock
A UL Type 1 Lock is highly resistant to manipulation and has a built in re-locker. With more than 1,000,000 possible combinations, this lock provides great security.
