Double Leaf Fire Door Factory-Direct Supply
Two-leaf fire-rated steel doors built for wide openings — CE and NFPA 80 certified, custom widths to 2400mm, factory-direct from Luoyang.
Where a single leaf won't clear the opening — equipment corridors, main building entrances, hospital wings — the double leaf configuration is the only compliant solution. We've been manufacturing these since our fire door line launched, and the coordination between the active and inactive leaf is where most factories cut corners. We don't.
What a Double Leaf Fire Door Is —
and Where Single-Leaf Falls Short
A double leaf fire door uses two independently hung door panels — an active leaf and an inactive leaf — mounted in a shared fire-rated frame. The combined clear opening typically runs 1200–2400mm wide, which is the range that building codes require for main egress routes, equipment access corridors, and high-traffic commercial passages where a single leaf would either block the opening width or create a door panel too heavy to operate safely.
The structural challenge with a double swing fire door is the meeting stile — the vertical edge where the two leaves close against each other. On a single-leaf door, the latch side closes against a fixed frame rebate. On a double-leaf, the active leaf closes against the inactive leaf, and that joint has to maintain the same smoke and fire seal integrity as the frame perimeter.
We run an intumescent strip along both meeting stiles, with a coordinated door closer sequence (the inactive leaf closes first, the active leaf closes second and latches over it) to ensure the seal compresses correctly under fire conditions. Get that sequence wrong and the door fails its rating at the meeting stile — which is exactly what happens when the door coordinator is undersized or misadjusted.
The fire rating carries across the full assembly: frame, both leaves, hardware, and seals are tested and certified together. Substituting hardware after the fact — swapping the door coordinator, changing the closer specification — can void the certification. We document the hardware schedule for every certified configuration we ship, so your downstream installer knows exactly what's in the assembly and what can't be changed.

The Meeting Stile and Coordinator: Where Double-Leaf Doors Succeed or Fail
This is the section most product pages skip, and it's the one that matters most for your downstream installation success.
The door coordinator is a mechanical device mounted at the top of the frame that controls closing sequence — it holds the active leaf open until the inactive leaf has fully closed, then releases the active leaf to close and latch over it. Without a properly specified coordinator, both leaves can race to close simultaneously, the active leaf arrives first, and the meeting stile seal never compresses correctly. The door looks closed. It isn't fire-rated closed.
We size the coordinator to the leaf weight and width of each configuration. A 900mm leaf at 45mm thickness runs approximately 55–65kg — that's a different coordinator specification than a 700mm leaf at the same thickness. We've seen imported assemblies where the coordinator was spec'd for a lighter door and the closing force was insufficient to pull the inactive leaf fully into the frame rebate under field conditions. The gap is 2–3mm. Invisible to the eye. Fails the smoke test.
Field Lesson
We started doing factory coordinator adjustment after getting feedback from a Gulf contractor whose site crew was re-adjusting coordinators without understanding the sequence logic — three doors on a hospital project failed their commissioning smoke test as a result.
Our hardware schedule for each certified configuration specifies the coordinator model, the closer power setting range, and the hinge count and placement. We ship the hardware pre-installed and adjusted on the door assembly — your installer sets the final closer speed on-site, but the coordinator adjustment is done at the factory and locked.
For panic hardware configurations — required on egress routes in most North American and European codes — we fit a coordinated panic bar set where the active leaf panic bar mechanically releases the inactive leaf latch before the active leaf opens. This keeps the egress function intact while maintaining the fire-rated closing sequence.
Discuss Hardware Configuration for Your Project
Factory-Locked Coordinator Adjustment
Coordinator sequence is set and locked at the factory. Installer adjusts only final closer speed on-site — no field re-sequencing required or permitted.
Weight-Matched Coordinator Sizing
900mm leaf at 45mm thickness: ~55–65kg. Each configuration receives a coordinator spec matched to actual leaf weight — not a generic off-the-shelf unit.
Coordinated Panic Bar for Egress Routes
Active leaf panic bar mechanically releases the inactive leaf latch before the active leaf opens — egress function preserved, fire-rated closing sequence maintained.
Fire Rating Options and Compliance by Market
CE certification covers the European market and is accepted in most Gulf Cooperation Council countries for import compliance. NFPA 80 covers the US and Canadian market — our fire door assemblies are designed and tested to NFPA 80 requirements, which means the label, hardware schedule, and installation instructions ship with every door set.
FD30
30 Minutes
UK, EU, Southeast Asia, general commercial applications. The baseline rating for most commercial corridor and office compartmentation requirements.
FD60
60 Minutes
Middle East, North America, high-rise commercial. Standard specification for most Gulf and North American projects where double-leaf fire doors are required.
FD90
90 Minutes
Stairwells, plant rooms, high-risk compartments. Required where building codes mandate extended compartmentation integrity for life-safety egress routes.
| Rating | Duration | Applicable Standards | Typical Markets |
|---|---|---|---|
| FD30 | 30 minutes | EN 1634-1, NFPA 80 | UK, EU, Southeast Asia, general commercial |
| FD60 | 60 minutes | EN 1634-1, NFPA 80 | Middle East, North America, high-rise commercial |
| FD90 | 90 minutes | EN 1634-1, NFPA 80 | Stairwells, plant rooms, high-risk compartments |
CE Certification — EU & GCC Markets
CE certification covers the European market and is accepted in most Gulf Cooperation Council countries for import compliance. For buyers supplying into the Australian market, our CE-certified assemblies are generally accepted under AS 1905.1 equivalency review — confirm with your local authority having jurisdiction, but we haven't had a clearance issue on this in our Australian accounts.
NFPA 80 — North American Market
Our fire door assemblies are designed and tested to NFPA 80 requirements. The label, hardware schedule, and installation instructions ship with every door set — your AHJ receives a complete compliance package, not a door that needs field documentation assembled after the fact.
SGS audit reports are available on request for buyers who need third-party documentation for their own import compliance files.

Double leaf fire doors are a standard specification item across four high-volume construction sectors. Understanding how each segment procures — and what documentation they require — determines whether your supply chain is positioned to win the order.
Healthcare Facilities
Hospital corridors, operating theater suites, and patient wing fire compartment boundaries all require wide, fire-rated openings — typically FD60 minimum, often FD90 in plant rooms and stairwells. A mid-size hospital project runs 80–200 double-leaf sets across the building.
Procurement Channel
Healthcare procurement typically goes through specialist medical equipment contractors who bundle door supply with installation. The ability to provide full hardware schedules and CE documentation is non-negotiable. We supply the complete package.
Commercial High-Rise & Mixed-Use
Main lobby entrances, elevator lobby fire doors, and floor-to-floor stairwell doors are almost always double-leaf in buildings above six stories. A 20-floor commercial tower typically specifies 40–80 double-leaf fire door sets.
Documentation Requirement
Developers in this segment buy through main contractors who need factory documentation for building control sign-off. Our CE certification and NFPA 80 compliance documentation travels with every shipment.
Educational Campuses
Universities and large secondary schools specify double-leaf fire doors at main building entrances and between fire compartments in multi-wing buildings. District-level procurement often runs 50–150 units per campus project, with repeat orders as buildings are added or renovated.
Typical Specification
Usually FD30 or FD60 with a vision panel in the active leaf. We accommodate glazed configurations with fire-rated glass up to 1.2m² per leaf.
Industrial & Logistics Facilities
Double-leaf fire doors are used at warehouse-to-office fire compartment boundaries and at loading dock access points where forklift clearance requires openings above 1800mm. This segment often specifies FD60 with a flush panel (no vision panel) and a heavy-duty threshold.
Why 1.2mm Body Gauge Matters Here
The doors take more abuse than commercial applications. The 1.2mm body gauge holds up where thinner panels dent. Logistics facility construction in Southeast Asia and the Gulf has driven significant growth in this segment over the last three years — the double-leaf fire door is a standard spec item on every new warehouse project.
Customization Parameters and Practical Limits
Double leaf fire doors have more customization variables than single-leaf — the leaf width split, the hardware coordination, and the frame configuration all interact. Here's what can be adjusted and where the limits are.
Leaf Width Split
Standard configurations use equal-width leaves (e.g., 2 × 800mm). Unequal splits are available — a common request is a 900mm active leaf paired with a 600mm inactive leaf, which gives a wider everyday opening while keeping the inactive leaf manageable.
Range
500mm – 900mm per leaf within the certified frame width range
Fire Rating
FD30, FD60, and FD90 are all available. Rating affects core specification, leaf thickness, and hardware requirements — a change in rating is not a simple swap, it's a different certified assembly.
Critical Note
Confirm your rating requirement before ordering. Rating changes require a fully different certified assembly.
Vision Panels
Fire-rated glazing is available in the active leaf, the inactive leaf, or both. Standard vision panel sizes run 200×600mm to 400×900mm. Larger glazed areas are possible but require fire-rated glass with a higher specification.
Max Glazed Area
Up to 1.2m² per leaf. Larger areas quoted separately with confirmed certified configuration.
Surface Finish
60+ RAL colors from our automated powder line. Textured finishes (fine texture, sand texture) are available. Stainless steel cladding on the active leaf face is available for healthcare and food-service applications where hygiene and impact resistance matter.
Special Finish
Stainless steel cladding available for healthcare and food-service environments.
Hardware Upgrades
Panic bar sets (EN 1125 compliant), electromagnetic hold-open devices (EN 1155 compliant for fire door hold-open), access control integration (electric strike, magnetic lock with fire alarm release), and heavy-duty hinges for high-frequency use are all available as configured options.
Standards
What Can't Be Changed After Certification
The core material, leaf thickness, and frame gauge are fixed within each certified configuration. Hardware substitutions that affect the closing sequence — changing the coordinator model, replacing the closer with a non-equivalent specification — void the CE marking.
Documentation
We document this clearly in the hardware schedule that ships with every door.

The double-leaf frame width roughly halves your container utilization — the number your freight team needs for landed cost calculations.
Pack Specification
-
Two leaves packed face-to-face in a single carton bundle
-
Frame sections in a separate reinforced carton with corner guards on all sections
-
Hardware in a labeled poly bag set inside the frame carton
-
Foam edge protection on leaf faces; pack spec survives standard port handling
Batch Traceability
Every carton carries a barcode linked to our production batch record. If there's a quality question on arrival, you can trace the unit back to its production date, line, and inspection record within minutes.
25–35 days for standard configurations from deposit confirmation. Custom configurations are quoted individually.
We've been loading these for export since 2012. The current pack spec came out of early feedback from a Dubai distributor whose site crew was finding corner damage on frame sections. We added the corner guards and the damage rate dropped to near zero.
Pre-Shipment Quality Checks Specific to Double-Leaf Assemblies
Standard fire door QC covers material, welding, coating, and dimensional checks — the same 5-stage process we run across all production. Double-leaf assemblies get two additional checks that single-leaf doors don't require.
Coordinator Sequence Test
Every double-leaf set is test-hung in our assembly station and the closing sequence is verified — inactive leaf closes fully into the frame rebate before the active leaf releases.
Gap at meeting stile in closed position: ≤1mm. Sets that don't pass get the coordinator re-adjusted before packing.
Meeting Stile Seal Compression Check
With both leaves closed, we check that the intumescent strips at the meeting stile are in full contact across the full height of the door.
Any gap in the seal contact is a failure — the door goes back for strip replacement or leaf adjustment.
Why These Two Checks Exist
These two checks add time to the assembly process. We built them into the production schedule after our QC manager — who came from automotive stamping — pointed out that a double-leaf fire door has two failure modes that a single-leaf doesn't, and both of them are invisible once the door is packed.
The checks stay in the process.
Both failure modes — coordinator sequence and meeting stile seal — are invisible once the door is packed. Catching them at the assembly station is the only point in the process where correction is practical before shipment.
Frequently Asked Questions
Direct answers to the specification and procurement questions we receive most often from architects, contractors, and distributors.
What is the maximum width for a double leaf fire door?
Standard certified configurations go up to 2400mm combined clear opening (two 1200mm leaves, though we more commonly see 900mm + 900mm or 900mm + 800mm splits in practice). Wider openings are possible with custom engineering, but the coordinator and closer specification changes significantly above 2000mm combined width — contact us with your opening dimension and we'll confirm the certified configuration.
Does a double swing fire door need a door coordinator?
Yes, in all certified configurations. The coordinator controls the closing sequence — inactive leaf first, active leaf second — which is required for the meeting stile intumescent seal to function correctly. A double-leaf fire door without a coordinator, or with a coordinator that's been disabled or removed, is not operating as a certified fire door assembly regardless of what the label says.
What fire rating do I need for a hospital corridor double-leaf fire door?
FD60 is the standard minimum for hospital corridor fire compartment boundaries in most markets (EN 1634-1 and NFPA 80). Stairwell and plant room doors in healthcare facilities are typically FD90. Confirm with the project's fire engineer — the specification is set by the building's fire compartmentation strategy, not by the door supplier. We can supply FD30, FD60, or FD90 in double-leaf configuration.
Can a double leaf fire door be held open legally?
Yes, with an electromagnetic hold-open device that releases automatically on fire alarm activation — this is the EN 1155 configuration. The door must still be fitted with a door closer and coordinator so it closes and latches when the hold-open releases. A door wedged open or held open with a non-certified device is not compliant and voids the fire rating. We supply EN 1155 hold-open configurations as a standard option.
What is the MOQ for double leaf fire doors?
50 units for standard catalog configurations (standard leaf widths, standard RAL colors, standard hardware schedule). Custom configurations — non-standard leaf width splits, custom frame sizes, special hardware — start at 100 units. Sample orders of 1–2 sets are available for specification approval before committing to a production run.
How does double-leaf fire door pricing compare to single-leaf?
We don't publish prices — B2B pricing depends on configuration, rating, hardware specification, and order volume. What we can tell you is that a double-leaf set uses roughly 1.8–2.0× the material of a single-leaf door of equivalent height, plus the coordinator and additional hardware. Send us your specification and target volume and we'll come back with a detailed quote.
