We offer bullet-resistant hollow metal doors and frames manufactured to UL-752 standards, from level 1 through level 8. These doors can withstand a variety of different ballistic levels, ranging from medium powered small arms up to high-powered rifles having 7.62 mm ammunition. The door frames for these doors are available in aluminum, slip in steel, and steel wrap around, all packed with the required ballistic fiberglass. The doors are available in a number of models such as standard hollow metal doors, doors with view window, narrow-lite doors, and half-lite doors. Our hollow metal doors are also offered in a double door configuration, to secure larger entries.
