Automatic Closing Fire Assemblies
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.
