Design of Hollow Metal Doors - Fire Rated Doors - Bullet Resistant Doors

Fire-rated doors are constructed of materials that work together to slow or stop the spread of flames, smoke and, in certain applications, radiant and conductive heat transfer. Common materials include wood, steel, fiberglass and fire-rated glass—or a combination of these materials.

Hollow metal doors are one of the most common types of doors used in commercial and industrial environments. A hollow metal door is composed of a steel frame that has steel panels laminated to both sides. The door is typically equipped with mounts for hinges and a pocket for a mortise lock.

Bullet resistant doors are often used in government buildings, cashier stands, high crime areas, or any structure where increased safety is desired.
