1. What Is a Fire Door?

A fire door is a specially designed door assembly tested to provide a specified level of fire protection for a designated period. Depending on its certified design, the assembly may include a fire-rated door leaf, frame, hinges, latch, door closer, seals and other approved hardware.

Fire doors are commonly installed in emergency staircases, fire exits, corridors, electrical rooms, generator rooms, warehouses and industrial facilities.

A properly specified fire door helps:

• Restrict the spread of fire between designated building areas.
• Reduce the movement of smoke when the assembly includes the required smoke-control features.
• Protect escape routes and support safer evacuation.
• Separate fire-risk areas from occupied spaces.
• Support compliance with applicable building and fire safety requirements.

Important: A fire-rated door is not automatically smoke-rated. Smoke-control performance must be verified separately where required.

2. UL Listed Fire Door Standards

When purchasing a fire door, check the certification of the exact door model and its complete assembly.

UL 10B and UL 10C apply to different fire-test conditions. The correct standard depends on the application and applicable building requirements.

Common Fire Door Ratings

Note: These are general rating options, not a statement that every model is available at every rating. The permitted rating, door size, frame, hardware and installation details must match the manufacturer’s certification and the project’s requirements.

3. Fire Door Technical Specifications

The following table provides a general purchasing specification for fire-rated steel doors. Final specifications must be confirmed against the selected manufacturer’s certified product documentation.

Certification warning: Do not describe a door as UL Listed merely because its steel construction, lock or hinges are fire-resistant. Verify the certification mark and listing details for the actual door assembly.

4. Fire Door Standard Sizes

Fire doors are available in different dimensions depending on the manufacturer, opening size, fire rating and installation requirements.

The following are example nominal door-leaf dimensions for preliminary planning. They are not universal UL-approved sizes.

Other sizes may be available by manufacturer and project specification.

Before ordering, confirm:

• Actual structural opening width and height.
• Door-leaf dimensions and frame dimensions.
• Wall thickness and frame depth.
• Single-leaf or double-leaf configuration.
• Required fire rating.
• Maximum permitted size under the certification.
• Clearance, swing direction and accessibility requirements.

Oversized doors must not be assumed to comply with a standard listing. Where a manufacturer offers an oversized classified product, obtain the relevant certification documentation and approval for the intended installation.

This is not a claim that every brand or model is UL Listed, or that all are available through Dusk Technology BD. Confirm the exact product certification and Bangladesh supply availability before procurement.
