Imagine a situation where seconds mean the difference between life and death. In a fire emergency, chaos often reigns, but there is one silent guardian that stands between safety and catastrophe: a high-quality fire door from a high quality fire rated door manufacturer. It’s not just a slab of metal or wood; it is an engineered lifesaver. As we move through 2025, the standards for building safety in India have never been stricter, and the demand for reliable protection has never been higher.
Welcome to KOR India. As a premier Fire Rated Door Manufacturer in India, we don’t just build doors; we build trust. Whether you are an architect designing a high-rise in Mumbai, a factory owner in Greater Noida, or a homeowner concerned about family safety, understanding the critical role of fire-rated doors is the first step toward a secure future.
Why Fire Safety is Non-Negotiable in 2025
The landscape of fire safety in India is evolving rapidly. Gone are the days when fire doors were an afterthought or a mere compliance tick-box. Today, with the stringent enforcement of the National Building Code (NBC) 2016 and the latest amendments to IS 3614, the focus has shifted entirely to performance, certification, and reliability.
A fire door serves two critical functions:
- Compartmentation: It traps the fire in a single area, preventing it from spreading to other parts of the building.
- Safe Egress: It shields escape routes (like staircases and corridors) from smoke and flames, allowing people to evacuate safely.
At KOR India, located strategically in Greater Noida, we have witnessed this shift firsthand. We have seen how a well-manufactured steel fire door can hold back a raging inferno for up to 120 minutes, giving fire services the precious time they need to act.
Decoding the Regulations: IS 3614:2021 and NBC 2016
For any responsible builder or property owner, navigating the maze of regulations can be daunting. As a leading fire rated door manufacturer, we believe in empowering our clients with knowledge.
The Gold Standard: IS 3614 (Part 2)
The Indian Standard IS 3614 is the bible for fire doors. The latest 2021 revision (IS 3614:2021) has aligned Indian manufacturing with global benchmarks like BS 476 and UL 10C.
- Integrity: This measures how long the door can physically block the fire. It must not develop cracks or gaps that allow flames or hot gases to pass through.
- Insulation: This is often overlooked but vital. It measures the door’s ability to stop heat transfer. A door that is red-hot on the safe side is dangerous; a true fire resistant door keeps the non-fire side cool enough to prevent combustion of nearby materials.
NBC 2016 Compliance
The National Building Code mandates that fire doors in India must be installed in:
- Fire exits and staircases (minimum 120-minute rating often required).
- Lift lobbies and corridors.
- Server rooms and electrical shafts.
Key Takeaway: Always ask for BIS certification fire doors. A door without a certification label is just a door, no matter what the seller claims. KOR India ensures every unit leaving our factory is CBRI tested and fully compliant.

KOR India’s Product Excellence: Engineered for the Toughest Conditions
We take immense pride in being one of the most versatile fire door manufacturers in the region. Our facility in Greater Noida is equipped with state-of-the-art machinery to produce doors that are as aesthetic as they are robust.
1. Steel Fire Doors: The Industrial Standard
Our flagship product, the steel fire door, is the preferred choice for commercial and industrial applications.
- Durability: Made from galvanized steel sheets (typically 1.2mm or 1.6mm thick), these doors are built to last decades.
- Fire Rating: Available in 60, 90, and 120-minute ratings (FD60, FD120).
- Applications: Ideal for factories, warehouses, and data centers where industrial fire doors are mandatory.
2. Glazed and Vision Panel Doors
Who says safety can’t be stylish? Our vision panel fire doors incorporate specialized fire-rated glass. This allows for visibility—crucial in hospital corridors and office cabins—without compromising the fire rating. We ensure the glass size strictly adheres to the IS 3614 fire doors limitations (max 0.06 sq. m for insulated doors) to maintain integrity.

3. Clean Room and Specialty Doors
For pharmaceutical and healthcare sectors, we manufacture clean room doors that offer fire protection while maintaining a sterile, dust-free environment.
Fire Rated Door vs. Ordinary Door: What’s the Difference?
Many customers ask us, “Why can’t I just use a heavy wooden door?” The difference lies in the engineering. A fire safety door is a complete “assembly”—the frame, the leaf, the hinges, and the closer all work together to survive extreme heat.
| Feature | Ordinary Door | Fire Rated Door (KOR India) |
| Material Core | Hollow or simple wood/particle board | Honeycomb, Rockwool, or Mineral Wool core |
| Sealing | Standard weather stripping | Intumescent strips (expand under heat to seal gaps) |
| Hardware | Standard brass/steel hinges | Ball-bearing fire-rated hinges (SS 304) |
| Certification | None required | CBRI tested / BIS certified mandatory |
| Purpose | Privacy and security | Life safety, smoke control, fire containment |
| Performance | Burns through in < 10 minutes | Holds fire back for 60–120 minutes |
Why Location Matters: The KOR India Advantage in Delhi NCR
When you are looking for fire door manufacturers Noida or fire door manufacturers Greater Noida, proximity plays a huge role in the success of your project.

This local presence combined with national-standard quality makes us the partner of choice for builders across North India.

Installation: The Backbone of Performance
Even the world’s best fire resistant doors will fail if installed incorrectly. A gap of just 3mm too wide can allow deadly smoke to penetrate.
Our Installation Process:
- Frame Fixing: The frame is grouted or bolted into the masonry with absolute precision.
- Door Hanging: The leaf is hung on high-load bearing hinges.
- Gap Check: We ensure the gap between the door and frame is between 3-4mm—enough to open, but tight enough for the intumescent seal to work.
- Hardware Fitment: Installing panic bars, door closers, and smoke seals. Fire door installation requires certified professionals, not just regular carpenters.
Pro Tip: Never prop a fire door open with a wedge or a chair. If a door needs to be held open (e.g., in a busy hospital corridor), use an electromagnetic holder connected to the fire alarm system. This ensures the door releases and closes automatically when the alarm sounds.
The Critical Importance of Maintenance
A fire door is a mechanical device. Over time, hinges can sag, closers can lose tension, and seals can become damaged. This is why fire door maintenance is not optional—it is essential.
KOR India’s Recommended 5-Point Health Check:
- Certification Label: Is the label still visible and legible on the top edge of the door?
- Gaps: Is the gap around the door consistent (less than 4mm)?
- Seals: Are the intumescent seals and smoke seals intact? (Look for damaged strips).
- Hinges: Is there any dark oil leaking? Are all screws tight?
- Closing: Open the door halfway and let go. Does it latch firmly on its own?
We offer annual maintenance contracts (AMCs) to ensure your NBC compliant doors remain compliant year after year.

Frequently Asked Questions (FAQ)
Q1: What is the difference between an FD30 and FD120 fire door?
A: The number refers to the minutes of fire protection. An FD30 door provides 30 minutes of protection, typically used in residential or low-risk areas. An FD120 door provides 120 minutes (2 hours) of protection and is standard for industrial fire doors, high-rise stairwells, and critical infrastructure.
Q2: Can I install a fire door myself?
A: No. Fire door installation is a specialized task. Incorrect installation (e.g., wrong gaps, non-fire-rated foam) voids the certification and renders the door useless in a fire. Always use certified installers like the team at KOR India.
Q3: Are glazed (glass) fire doors as safe as steel ones?
A: Yes, provided they use certified fire-rated glass (like Borosilicate or Ceramic glass) and are manufactured by a licensed fire rated door manufacturer. We ensure our vision panel fire doors meet all IS 3614 integrity criteria.
Q4: Do KOR India doors come with a warranty?
A: Absolutely. All our fire safety doors come with a manufacturing warranty against defects. We also provide test certificates (CBRI/BIS) for your building completion (OC) requirements.
Q5: Why is the intumescent seal important?
A: The intumescent seal is a strip around the door frame that expands up to 40 times its size when exposed to heat. This expansion seals the gap between the door and frame, blocking smoke and fire from passing through. It is a critical component of any NBC compliant door.
