About Fire Shaft Doors

A fire shaft door, also known as a fire-rated shaft door or fire door assembly, is a specially designed door system intended to provide fire resistance and compartmentalization in buildings, particularly in areas such as elevator shafts, stairwells, and other vertical openings. These doors play a crucial role in containing the spread of fire and smoke, thereby enhancing the safety of occupants and reducing property damage.

Key Features of Fire Shaft Doors:

- Fire Resistance Rating: Fire shaft doors are tested and rated according to their ability to withstand fire for a specified duration, typically measured in minutes or hours. Common ratings include 20-minute, 45-minute, 60-minute, and 90-minute doors.

- Self-Closing Mechanism: These doors are equipped with self-closing devices that ensure they automatically close after being opened, maintaining the fire-resistant seal.

Superior Fire Protection and Compartmentation

Designed to withstand intense heat, these fire shaft doors offer up to 120 minutes of fire resistance, safeguarding critical building shafts and enclosures. The integrated mineral wool infill and reinforced pressed GI steel frames create a formidable barrier against flames, preventing the spread of fire and smoke. This makes them indispensable in maintaining compartmentation in multi-storey buildings.

Customized To Suit Every Project

With flexible options for door width, height, colors, and finishes, our fire shaft doors seamlessly adapt to varied architectural requirements. Vision panels, acoustic performance, and hardware compatibility enhance functionality, while the choice of different mounting types ensures straightforward integration into new or existing structures. Clients can choose from standard or custom specifications according to their needs.

FAQ's of Fire Shaft Doors:

Q: How are fire shaft doors installed, and what mounting options are available?

A: Fire shaft doors can be installed using either wall or shaft mounting methods, accommodating both recessed and surface-mounted setups. This ensures versatility for different project requirements and enables seamless integration into new constructions or retrofits.

Q: What is the fire resistance rating, and what benefits does it provide?

A: These doors offer a fire resistance rating of up to 120 minutes, backed by certification from NABL accredited labs. This high rating ensures critical areas are effectively compartmentalized, minimizing fire spread and offering vital evacuation time for occupants.

Q: Where can these fire shaft doors be used?

A: They are ideal for use in elevator shafts, staircases, duct and utility shafts across commercial, residential, and industrial buildings, providing enhanced fire safety and compliance with statutory requirements in high-traffic environments.

Q: What customization options are available for these doors?

A: Clients can opt for different RAL colors, stainless steel finishes, optional vision panels, and improved acoustic performance (up to 33 dB). Sizes can also be tailored to project needs, up to a maximum of 1200 mm wide and 2400 mm high.

Q: How does the sealing system protect against smoke and flames?

A: The perimeter of each door is fitted with advanced intumescent strips and smoke-proof gaskets, expanding under heat to block smoke and flames, enhancing compartmentation and protecting occupants during a fire.

Q: What hardware is supported for access and security?

A: These doors are compatible with mortise locks, lever handles, panic bars, door closers, and electromagnetic holders, ensuring versatility and compliance with access control and security requirements.

Q: What makes these doors suitable for high-traffic and tough environments?

A: Constructed with pressed GI steel, fire-retardant coatings, and equipped with heavy-duty ball bearing hinges, these doors offer high tensile strength, weather and corrosion resistance, and can handle frequent operation common in busy facilities.
