Fire Rated Doors

Fire-rated doors are an important part of a building's passive fire protection system. They are installed at designated openings in fire-rated walls to help contain fire and restrict its spread between different areas of a building. By maintaining compartmentation and protecting designated escape routes, they provide valuable time for occupants to evacuate and emergency teams to respond.

When evaluating Fire Rated Doors Manufacturers in India, it is important to look beyond the fire rating mentioned in a product description. The performance of a fire door depends on the complete assembly, including the shutter, frame, hinges, locking arrangement, seals, door closer and any vision panel. These components must be compatible with the tested configuration and installed according to the approved specifications.

Aurotoshi manufactures 120-minute fire-rated steel door sets tested in accordance with IS 3614 Part 2 and BS 476 Part 22. Available in D-handle and mortice lock or panic bar configurations, these doors are designed for commercial, industrial and institutional buildings where fire compartmentation and controlled access are important.

The location and purpose of a fire door depend on the building layout, fire-safety strategy and requirements of the designated compartment or escape route. They are commonly specified in the following environments:

• Pharmaceutical and healthcare facilities: Used at designated openings in areas where fire compartmentation, controlled movement and safe evacuation are important.

• Hospitals and medical centres: Installed along protected corridors, stairways and other designated routes to support building fire-safety arrangements.

• Manufacturing plants: Help separate production areas, utility rooms, electrical rooms and other designated fire compartments.

• Warehouses and logistics facilities: Used between storage areas, operational zones and protected circulation routes, according to the building's fire-safety plan.

• Data centres and IT facilities: Specified at designated openings where fire separation is part of the facility's overall protection strategy.

• Commercial buildings and offices: Used in staircases, service areas, plant rooms and other locations identified in the building's fire-safety design.

• Hotels and public infrastructure: Installed at designated compartment boundaries and protected escape routes to support occupant safety.

The required fire-resistance period, door configuration and hardware should always be determined by the building's approved fire strategy and applicable regulations.

A fire-rated door should be assessed as a complete door set rather than as an individual steel shutter. Each component contributes to the assembly's ability to perform under fire-test conditions.

Important components include:

• Fire-rated shutter: The main door leaf, constructed with the specified steel skins and insulation infill.

• Steel door frame: Provides the supporting structure and the correct rebate profile for the door leaf.

• Intumescent seals: Expand when exposed to heat and help close gaps around the door edges.

• Fire-rated hinges: Support the door leaf and maintain its intended movement and alignment.

• Door closer: Returns the door to its closed position after use, helping maintain the compartment boundary.

• Locking and panic hardware: Provides the required access control or emergency-release function.

• Fire-rated vision panel: Allows visibility through the door when included in the tested assembly and installed using the approved glazing arrangement.

For a certified fire door, the test evidence must correspond to the actual assembly being supplied. Changes to the frame, glazing, hardware or installation details should not be assumed acceptable unless they are covered by the relevant test evidence or approved assessment.

The hardware configuration should be selected according to how the doorway will be used. Aurotoshi offers two options, both with a specified 120-minute fire rating.

Fire Door with D-Handle and Mortice Lock

This configuration is suitable for rooms, corridors, plant rooms and service areas where the opening forms part of a fire compartment and controlled access is required.

The mortice lock provides a conventional locking arrangement, while the overhead door closer returns the leaf to its closed position after passage. It is generally considered for locations where everyday access and security need to be managed together.

Fire Door with Panic Bar

A panic bar configuration is intended for emergency exits, stairways and designated escape routes where occupants need to open the door quickly from the escape side.

The push-bar mechanism allows the door to be released with a single push, without requiring a key or conventional handle operation from the escape side. Aurotoshi offers single-point panic hardware for single-leaf doors and triple-point hardware for double-leaf configurations, as specified for the product.

The appropriate arrangement should be confirmed against the building's occupancy, escape-route design and applicable fire and life-safety requirements.

The choice between a single-leaf and double-leaf fire door depends mainly on the clear opening required and the movement expected through the doorway.

Single-leaf fire doors use one hinged shutter and are suitable for standard-width openings in corridors, service rooms, plant areas and other locations primarily used for pedestrian movement.

Double-leaf fire doors use two shutters to provide a wider clear opening. They are considered for larger doorways, equipment movement and routes where the full opening width is required. The active and secondary leaf arrangement, locking hardware and closing sequence must be specified as part of the tested door set.

Aurotoshi offers both configurations in its D-handle and panic bar variants. Standard sizes include single-leaf openings of 1200 × 2100 mm and 1200 × 2400 mm, and double-leaf openings of 1500 × 2100 mm and 1800 × 2100 mm. Project-specific dimensions should be confirmed against the approved door schedule and available test documentation.

Selecting a fire door involves more than matching a product to an opening dimension. Architects, consultants, contractors and facility managers should review the following points before finalising a specification:

1. Required fire rating: Confirm whether the opening requires a 60-minute, 90-minute or 120-minute fire-resistance period, according to the approved fire-safety design.

2. Opening dimensions: Check the structural opening, required clear passage and whether a single-leaf or double-leaf arrangement is appropriate.

3. Door location: Identify whether the door is installed in a corridor, plant room, staircase, service area or emergency exit.

4. Hardware configuration: Select a D-handle and lock for controlled access or panic hardware where emergency release is required.

5. Test documentation: Review the applicable test reports and certification documents for the complete shutter, frame, glazing and hardware configuration.

6. Installation requirements: Check frame fixing, wall construction, clearances, sealing and installation details against the approved specifications.

7. Maintenance arrangements: Plan periodic inspection of hinges, door closers, locks, panic bars, seals and other components to keep the door operating correctly.

Working through these requirements helps ensure that the selected door is appropriate for its location and intended function.

A fire door can only perform as intended when it is correctly installed and maintained. Even a tested door assembly may not provide its expected performance if the frame is incorrectly fixed, seals are damaged, hardware is unsuitable or the door is routinely left open.

Regular inspection should cover the condition of the shutter and frame, hinge fixings, door closer operation, locking mechanism, panic bar, intumescent seals and vision panel. The door should close fully without obstruction and latch as intended.

Aurotoshi provides installation assistance and Annual Maintenance Contract (AMC) support for its fire-rated door systems. Maintenance services include hinge and closer servicing, panic bar and lock checks, seal and vision panel inspection, frame and anchor checks, and service documentation. Breakdown support and spare parts assistance are also available according to the agreed service scope.
