Fire rated doors come in many different styles, species, and fire ratings. Fire rated steel doors play a vital role in keeping people safe and minimize property damage during a fire. Fire doors control the spread of fire and smoke for up to three hours; metal fire doors are an economical alternative to fire doors when more than a 20-minute rating is required. Steel is the sole door material to deliver a three-hour fire rating.

Arty’s Door Shop fire rated door options include 20-minute fire rated doors, 45-minute fire rated doors, 60-minute fire rated doors, 90-minute fire rated doors, and three-hour fire rated doors. Heavy duty 18 gauge steel doors with rigid honeycomb or polystyrene cores.

Fire door openings are classified by their locations. The specific building location determines the length of exposure protection required based on the potential fire hazard of the particular area. The openings are in walls that separate building or divide a single building. 90-minute fire ratings are used for enclosures, a vertical communication or egress through buildings. Examples include stairwells and elevators, boiler rooms and in exterior walls that have the potential for severe fire exposure from the outside of the building. A 45-minute fire rating is used where there are openings in a corridor or room partition; a door with this rating may also be located in the exterior wall of the building subject to moderate fire exposure from the outside of the building.

20-minute fire ratings are commonly found in openings where smoke and fire control is required from residential homes. The main part of the home going into the garage is a common opening in which a 20-minute fire rated door is used.
