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.

Trudoor is an authorized WHI fire-labeled shop (Warnock Hersey / Intertek), enabling us to modify, re-certify and label fire-rated doors and frames. Our facility undergoes routine inspections to verify that modifications are done in compliance with the requirements of the Intertek specification listings.

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

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.
