Introduction — Fire Doors Are Not Just Fittings, They Are Life-Saving Barriers
Fire safety is one of the most critical components in any commercial or industrial building. Whether it’s a hospital, manufacturing unit, shopping mall, warehouse, educational institute, power plant, or corporate building, installing certified fire doors is not just recommended — it is legally mandatory under NBC (National Building Code of India), Factory Act, and Fire NOC Requirements.
A fire compartment is only effective if the doors between those sections can resist fire and smoke for a fixed duration, preventing spread and allowing safe evacuation. This is where Hercules Doors, a leading Indian manufacturer of Steel Fire Doors, Acoustic Cum Fire Doors, Metal Fire Rated Doors, Single Leaf & Double Leaf Fire Proof Doors, and Fire Hose Cabinet Doors, delivers tested and certified protection for every building type.
Selecting the correct fire door is crucial — and this guide will help you do it right.
Fire Door Specification Checklist for Commercial & Industrial Projects
1. Identify the Required Fire Rating
Fire resistance is measured in minutes — 60, 90, or 120 minutes typically. The fire authority or project consultant usually specifies this based on building occupancy and risk level.
| Building Zone | Required Rating | Recommended Hercules Doors Product |
|---|---|---|
| Staircase & Escape Route | 120 mins | Double Leaf Fire Proof Door |
| Electrical Room / Server Room | 90 mins | Steel Fire Door |
| Office Corridor / Lift Lobby | 60 mins | Single Leaf Fire Proof Door |
| Boiler / DG Room | 120 mins | Metal Fire Rated Door |
2. Select Door Material & Structure
| Requirement | Door Type | Hercules Solution |
|---|---|---|
| Industrial & Heavy Duty | Steel | Steel Fire Doors |
| Soundproof + Fire Safety | Acoustic | Acoustic Cum Fire Doors |
| High Durability | Metal | Metal Fire Rated Doors |
3. Choose Single or Double Leaf Configuration
| Opening Width | Best Door Type |
|---|---|
| Less than 1100 mm | Single Leaf Fire Proof Door |
| More than 1100 mm | Double Leaf Fire Proof Door |
Hercules Doors provides custom sizes as per architect drawings.
4. Include Mandatory Fire Door Hardware
A fire-rated door is incomplete without certified hardware, otherwise it fails in fire audits.

Fire-Rated Door Closers
Panic Bars / Exit Devices
Intumescent Strips & Smoke Seals
Fire-Rated Hinges
Vision Panels / Fire Glass (Optional)
5. Include Fire Hose Cabinet Doors for Hydrant Systems
In industrial and commercial projects, hydrant cabinet doors must be fire-resistant. Hercules offers Fire Hose Cabinet Doors with powder-coated or glass panel design.
6. Verify Fire Certification & Test Standards
Hercules Doors manufactures as per:
IS 3614 Part 2 — Fire Check Doors
NBC Fire Norms (National Building Code of India)
BS 476 / UL-based Testing
Certificates must be submitted to Fire Authority during NOC approval.

Common Mistakes to Avoid While Choosing Fire Doors
Even experienced contractors make these errors:
Choosing a non-certified supplier
Installing door without correct hardware
Painting over intumescent seals
Using wooden frames instead of metal frames
Leaving gaps at bottom or sides
Hercules ensures zero compromise by delivering factory-fitted, code-compliant assemblies.
Role of Fire Doors in Fire NOC & Legal Compliance
Fire departments will not issue Fire NOC if:
Doors are not certified
Panic bars are missing in emergency exits
