Steel Fire Door: Comprehensive Guide
Steel fire doors are fire-resistant barriers designed to compartmentalize fires, prevent smoke spread, and provide safe evacuation routes. They are mandatory in commercial, industrial, and multi-residential buildings under IBC, NFPA 80, and UL 10C standards.
1. Key Features
✔ Fire Resistance Rating – 20 mins to 3+ hours (tested to UL 10C, BS 476, EN 1634).
✔ Steel Construction – 18-20 gauge steel skins with fireproof core (mineral wool, gypsum, vermiculite).
✔ Smoke Seals – Intumescent strips expand at ~200°C to block smoke/flames.
✔ Self-Closing Mechanism – Ensures automatic shut during a fire.
✔ Security Reinforcement – Often combined with burglar-proof or bullet-resistant features.
2. Construction & Materials
A. Core Materials
| Type | Fire Rating | Best For |
|---|---|---|
| Mineral Wool | 60–180 mins | High-risk areas (stairwells, labs) |
| Vermiculite Board | 30–120 mins | Lightweight doors (offices, hospitals) |
| Gypsum Core | 60–90 mins | Low-cost fire resistance |
B. Steel Frame & Skin
-
18-20 gauge steel (1.0–1.5mm thickness).
-
Welded seams for structural integrity.
-
Anti-corrosion coating (zinc or powder-coated finish).
C. Fire-Rated Hardware
-
Hinges – 3+ heavy-duty steel hinges (melting point >800°C).
-
Locks & Latches – UL-listed panic hardware or mortise locks.
-
Door Closers – Adjustable, heat-resistant.
3. Fire Ratings Explained
| Rating | Protection Time | Common Applications |
|---|---|---|
| 20-30 mins (Class C) | Partial fire barrier | Storage rooms, offices |
| 60-90 mins (Class B) | Full evacuation time | Hospitals, schools |
| 120-180+ mins (Class A) | High-risk containment | Industrial plants, stairwells |
4. Manufacturing Process
-
Steel Cutting & Forming – Laser-cut steel sheets shaped into door panels.
-
Core Assembly – Fire-resistant material inserted between steel skins.

-
Industrial Facilities (factories, power plants).
-
Residential High-Rises (fire escape corridors).
-
Hospitals & Schools (safe evacuation paths).
