Fire Rated Steel Doors UK
Fire rated steel doors are a critical solution for UK buildings needing robust fire containment and physical security.
Samson Doors offers an industry-leading collection, covering internal and external steel doors, sliding fire doors, certified emergency exit sets, and a wide selection of fully certified doorsets from leading brands, fully compliant with UK and European regulations.
What is a Fire Rated Steel Door?
A fire rated steel door is a specialist doorset engineered to withstand fire and smoke for a certified period (typically 30, 60, 120, or 240 minutes). It provides compartmentation, preserves escape routes, and protects both lives and assets by forming part of the building’s fire strategy.
Fire rated steel doors are required wherever Building Regulations and the fire strategy specify a fire-resisting door assembly, especially in commercial, industrial, and multi-occupancy residential buildings in the UK.
Key standards and certification include:
- UK fire tests: BS 476: Parts 20 & 22
- European fire tests: BS EN 1634-1, BS EN 16034
- Product certification: CERTIFIRE, third-party accreditation
- Marking: CE / UKCA marking where applicable
Hinged Fire Rated Steel Doorsets
Selecting a fully certified fire rated steel doorset is essential for safety, compliance, and long-term performance. Samson Doors supplies a top UK range from proven manufacturers, always delivered as pre-assembled doorsets for rapid, reliable installation and consistent test-backed performance.

All hinged fire rated doorsets are supplied with factory-fitted hardware and fire-tested glazing (where specified), ensuring that the complete assembly matches the tested configuration.
Why Buy a Certified Fire Rated ‘Doorset’?
Always specify a fully tested and certified doorset—not just a door leaf and separate components. A fire rated doorset is designed, tested, and supplied as a complete system, rather than relying on on-site assembly from mixed parts.
Key reasons to choose doorsets:
- Complete safety: The door leaf, frame, seals, hinges, closers, and ironmongery are tested together as a single unit and then manufactured repeatedly to that tested specification.
- Regulatory compliance: Fully tested doorsets make it far easier to demonstrate compliance with Building Regulations, Approved Document B, and insurance requirements.
- Reliability on site: Factory-assembled, pre-hung sets provide consistent clearances and alignment, reducing installation errors and call-backs.
- Warranty & traceability: You receive full system documentation and identification, making ongoing fire risk assessments and maintenance much simpler.
Mixing loose leaves, generic frames, and non-tested hardware can invalidate the fire certification and compromise safety. Always source from reputable, third-party tested manufacturers.
Sliding Fire Rated Steel Doors
Sliding fire doors are ideal for large openings in industrial and commercial environments where wide clear openings are needed during normal operation, but robust compartmentation is required in a fire.
Hörmann Sliding Fire Doors
- Available in multiple fire-resistance classes (for example T30, T60, T90, and higher), with models certified up to 120 or 240 minutes depending on specification.
- Single and double-leaf designs with optional smoke-tight and acoustic configurations for escape routes and high-traffic areas.
- Large size capability, smooth running gear, and options for integrated wicket/escape doors to maintain pedestrian access.
Fire Exit Steel Doors
Fire rated fire exit doors combine the life-safety requirements of emergency egress with fire resistance and security.
Samson Fire Exit Steel Doorsets
- Available with fire ratings up to 240 minutes in certain configurations, in single and double-leaf options (subject to test evidence).
- Fitted with certified panic and emergency exit hardware to BS EN 1125 / BS EN 179 for safe and compliant escape routes.
- Offered in over 50 standard colours, with options for acoustic upgrades, enhanced security, and vision panels where certification allows.
EI Rated Fire and Thermal Doorsets
EI (Integrity & Insulation) doorsets are the newer European standard for comprehensive fire protection and are increasingly specified in the UK, especially for higher-risk and multi-occupancy buildings.
- E – Integrity: Prevents the passage of flames and hot gases.
- I – Insulation: Limits heat transfer, ensuring the non-fire side does not reach dangerous temperatures.
Common EI ratings include EI30, EI60, EI90, and EI120.
Why EI?
- Aligns with European and emerging UK specifications for full fire resistance performance.
- Provides enhanced protection against both flames and radiant heat, crucial for escape routes, communal areas, and high-occupancy premises.
- Increasingly required by fire engineers, insurers, and building control for healthcare, residential, and industrial projects.
Samson Doors can supply EI-rated steel doorsets for high-risk locations and insurance-driven projects where full integrity and insulation performance is demanded.
UK Regulations & Certification
Fire rated steel doors must be correctly specified and evidenced to meet UK regulations:
- UK tests: BS 476: Part 22 (fire resistance of non-loadbearing elements).
- European tests: BS EN 1634-1 and BS EN 16034 for fire resistance and performance of door assemblies.
- Product certification: CERTIFIRE and other third-party schemes to verify test data and ongoing production control.
- Approved Document B (Fire Safety) in England and Wales sets out where fire doors are required, minimum ratings, and installation expectations.
Key Benefits of Fire Rated Steel Doors
- Life safety and property protection through certified fire resistance.
- High security and strength, using robust steel construction and multi-point locking where specified.

FAQs
What’s the difference between FD30, FD60, FD120 and FD240?
FD ratings indicate how long a fire door has been tested to resist fire, expressed in minutes (for example FD30 = 30 minutes, FD60 = 60 minutes, FD120 = 120 minutes, FD240 = 240 minutes). Higher ratings provide longer protection; the correct rating should be chosen in line with the building’s fire strategy and Building Regulations requirements.
Can fire doors include glazing?
Yes. Fire doors can incorporate vision panels or larger glazed areas, provided the glass, beads, seals and framing are all tested and certified as part of the same fire doorset and carry the same fire rating. Using non‑approved glass or components can invalidate the fire certification.
How do I ensure compliance with UK regulations?
Start with your fire strategy and the guidance in Approved Document B. Always specify fully tested, factory‑assembled fire doorsets, and ask for evidence of testing to BS 476:22 and/or BS EN 1634‑1, backed by recognised third‑party certification (such as CERTIFIRE). Ensure installation follows the manufacturer’s instructions and any project-specific fire‑stopping details so the door performs as tested.
What is EI rating and why is it important?
An EI rating confirms that a doorset has been tested for both integrity and insulation: “E” means stopping flames and hot gases, “I” means limiting heat transfer to the non‑fire side. EI30, EI60 and higher ratings offer additional protection for escape routes and high‑risk areas by reducing the risk of heat spread, and are increasingly specified by fire engineers, insurers and building control.
How are your steel fire doors supplied and installed?
Our steel fire doors are supplied as pre‑assembled doorsets, with the door leaf, frame and core hardware factory‑fitted. This doorset approach makes installation faster and more consistent than building up separate leaves, frames and ironmongery on site, and helps ensure the door matches the configuration that was originally fire‑tested.
Are stainless steel and special finishes available?
Yes. As well as hygienic and corrosion‑resistant stainless steel finishes, we offer a wide range of polyester powder coated colours and realistic woodgrain laminate options. This allows you to match surrounding décor and choose a finish that suits both the environment and the required durability.
What are typical lead times for fire rated steel doors?
Most fire rated steel doorsets are manufactured to order. Typical lead times are around 2–4 weeks from approval of drawings, depending on specification and quantity. Because the doors are supplied pre‑assembled, on‑site fitting is usually quicker and more predictable than with kit‑form doors.
