Fire-Rated steel doors play a vital role in keeping people safe and minimizing property damage during a fire. Labeled fire doors control the spread of fire and smoke for up to 3 hours. Metal fire doors are an economical alternative to wood fire doors when more than a 20-minute rating is required. Steel is the sole door material to deliver a 3-hour fire-rating.

  • Heavy-Duty 18-Gauge Steel Doors
  • Rigid Honeycomb or Polystyrene Core

Fire door openings are classified by their locations in a building. Location determines the length of exposure protection required, based on the potential fire hazard of that particular area. The opening classifications are shown below. Fire-protection ratings tested and classified by: Warnock Hersey-WHI or Underwriters Laboratories- UL. The local Authority Having Jurisdiction must be the final authority on fire door assembly issues.

Note: Most exterior doors do not require fire-rating unless there is the potential for fire exposure from the outside of the building. See Flush Metal Doors for non-rated doors, which are made from the same construction as a fire-rated metal door.

Fire-Rated doors are required to be self-closing and positive latching. Frame and Hardware must also carry the appropriate fire label.
