This heavy duty security door from The Great Door Company in South Africa is reinforced with a steel inner core, 5 additional bolts, and a steel frame to withstand burglars and direct attacks. The armored lock in this door is protected with manganese plates, and each bolt is enclosed in a protective sleeve in the door. The door is thermally insulated and is rated fire resistant for up to 45 minutes at 1000 degrees F. The rock wool in the door also makes the door a good sound insulator.
