Single Fire Door | EUWOO
Single leaf fire door — the most stocked configuration in commercial construction, built to NFPA 80 and CE from a factory that's been running fire door lines since 2011.
FD30 to FD120 ratings. 1.0–1.5mm SPCC steel body. Standard widths 700–1200mm, custom dimensions available. MOQ 50 units for catalog stocking, 100 units for custom builds.
What a Single Fire Door Is — and Where It Fits in Your Product Mix
A single fire door is a single-leaf fire-rated door assembly: one active leaf, one frame, intumescent perimeter seal, and the hardware package required to maintain the fire resistance rating. It's the baseline configuration in the fire door category — the SKU that moves in the highest volume for distributors, covers the widest range of project applications, and is the natural starting point for any fire door catalog.
The distinction from a double leaf fire door matters commercially, not just technically. Single leaf doors fit standard commercial openings (700–1200mm clear width), require no active/passive leaf sequencing hardware, and install faster — which means lower labor cost for your contractor customers and fewer callbacks. For a distributor building a fire door line, the single leaf configuration is where you stock depth; the double leaf is where you stock breadth.
We manufacture single fire doors across the full rating range — FD30 through FD120 — in our dedicated fire door production lines in Luoyang. The same NFPA 80 and CE certifications that cover our full fire door range apply to this configuration. If you're sourcing for North American, European, Gulf, or Southeast Asian markets, the compliance documentation is ready.

Cost-sensitive markets. Appropriate only where the application is genuinely low-abuse.
Standard commercial spec. What we recommend for most distribution and project applications.
Schools, hospitals, industrial corridors — where the door takes daily punishment. Note: adds 12–18% to freight cost per container. Worth the conversation before you lock in a spec.
Fire Rating Selection: Which FD Rating for Which Market
The category page covers fire rating mechanics in full — see the fire door rating guide. For single leaf doors specifically, here's the practical breakdown your buyers will ask about.
FD30
Entry-Level Stocking SKU
Minimum interior compartmentation in low-rise commercial buildings. Moves well for distributors serving general construction and residential-scale commercial fit-out.
- Thinner leaf — lower freight cost per unit
- Lighter weight, easier installation
- General construction & residential-scale commercial
FD60
Volume SKU — Start Here
The volume SKU for commercial construction in North America and the Gulf. Required for stairwells in mid-rise buildings, plant rooms, and any opening in a rated wall separating occupancies.
- Stairwells in mid-rise buildings
- Plant rooms & rated wall separations
- If building a single-SKU catalog, start here
We ship more FD60 single leaf doors than any other configuration in our fire door range.
FD90 / FD120
High-Value Specialist SKU
Electrical rooms, server rooms, high-rise stairwells, storage areas with flammable materials. Smaller order volumes, higher unit value, less price sensitivity.
- Higher unit value, less price sensitivity
- 64mm leaf at FD120 — noticeably heavier
- Factor freight & installation labor into quotes

Where Single Leaf Fire Doors Sell — Market Segments Worth Building Into Your Catalog
FD60 single leaf steel fire doors are the highest-velocity SKU in any fire door distribution catalog. They're a code-mandated purchase, not a discretionary one — demand is predictable and buyers are less price-sensitive than on general commercial doors.
Commercial Construction & Fit-Out
Office buildings, hotels, and mixed-use developments specify single fire doors at every stairwell, corridor compartmentation wall, and plant room. A mid-size office tower typically requires 150–400 single leaf fire door sets.
Margin opportunity
Contractors sourcing factory-direct rather than through a local distributor protect 15–25% margin on that volume. If you're the distributor, that margin is yours to capture by being the direct-import source in your market.
Building Materials Distribution
FD60 single leaf steel fire doors are the highest-velocity SKU in any fire door distribution catalog. They're a code-mandated purchase, not a discretionary one, which means demand is predictable and buyers are less price-sensitive than on general commercial doors.
Catalog consolidation benefit
A distributor stocking FD30 and FD60 single leaf from one supplier consolidates compliance documentation and simplifies reorder logistics. This segment has grown consistently over the past three years.
Property Developers — Middle East, Southeast Asia & Africa
Large-scale residential and commercial developers building at scale need fire door compliance at certificate of occupancy. Single leaf is the dominant configuration across most building types.
Factory-direct advantage
Developers sourcing factory-direct for multi-building projects get consistent product across all buildings and a single audit trail — one certification package, one supplier contact, one QC standard.
Facilities Management & Retrofit
Existing buildings undergoing fire safety upgrades need replacement fire doors matched to existing frame dimensions. Single leaf is the most common replacement configuration in this segment.
- Custom sizing capability handles non-standard openings
- 25–35 day lead time on standard orders serves retrofit timelines
- Drop-in replacement for most standard opening sizes
Overseas Manufacturers & OEM Buyers
If you're building a door product line under your own brand, the single leaf fire door is the anchor SKU. We handle OEM private-label programs from 100 units: your branding, your packaging, your label — manufactured to your spec on our certified production lines.
- OEM programs from 100 units
- Your branding, packaging, and label
- Manufactured to your spec on certified lines
- Single leaf fire door as anchor SKU for your range
Segment Summary
One SKU, Five Buyer Types — All Code-Mandated Demand
Across commercial construction, distribution, developer projects, retrofit, and OEM programs, the single leaf fire door is a non-discretionary purchase driven by building code. That makes it a reliable catalog anchor with predictable reorder patterns — unlike discretionary commercial door categories where demand tracks economic cycles.

How We Build This Door: Process Details That Affect Your Downstream Quality
The single leaf fire door looks straightforward from the outside. The production decisions that determine whether it performs in a real fire event — and whether your downstream customers have warranty claims — happen inside the leaf and at the frame joint.
Steel Body and Core Assembly
±0.5mm toleranceThe door leaf is a steel shell filled with fire-resistant core material. We form the outer and inner face panels from SPCC cold-rolled steel coil on our CNC press brake lines, holding panel dimensions to ±0.5mm tolerance. The panels are welded on three edges, the core material is inserted, and the fourth edge is welded closed.
FD30 / FD60: Mineral wool board — industry standard for this rating range, good balance of fire resistance and door weight.
FD90 / FD120: Perlite composite — handles higher thermal load without the weight penalty of thicker mineral wool.
The core fill is tight — no voids, no gaps at the corners where the thermal bridge would be.
Intumescent Seal Installation
Mechanically retainedThis is the component that most often determines whether a fire door passes or fails in service. We machine a continuous channel around the perimeter of the door frame and press-fit the intumescent strip into it — mechanically retained, not adhesive-bonded.
Why it matters: Surface-applied seals delaminate in humid climates within 18–24 months. A recessed channel seal stays in place for the life of the door.
The strip is rated to the door's fire resistance class — FD60 doors don't get FD30 strip. We've seen competitor product arrive with the wrong-grade strip installed. It's not detectable by visual inspection, which is why we document the strip specification on every production batch record.
Weld Seam Treatment Before Coating
Zinc phosphate pre-treatmentEvery weld seam on the door body is ground flush before the door enters the phosphate pre-treatment bath. This matters for two reasons: coating adhesion is weakest at unground weld seams because the heat-affected zone changes the surface chemistry, and any surface irregularity at the seam becomes visible through the powder coat finish.
We switched to zinc phosphate pre-treatment in 2020 — better corrosion resistance at the substrate level than the iron phosphate wash used previously. 500-hour salt spray test results confirmed the improvement. Zero delamination at weld seams on the current process.
Frame-to-Leaf Fit Verification
100% test-fittedEvery single fire door is test-fitted with its frame before packing. We check the perimeter gap — it needs to be 3–4mm consistent around the full perimeter.
Too Wide
Door fails smoke integrity
Too Tight
Binds — won't close in emergency
Our CNC forming holds tolerances tight enough that fit failures are rare, but we check every unit anyway. A door that doesn't fit its frame is a warranty claim waiting to happen, and we'd rather catch it on our floor than in your customer's building.

No charge for the design consultation.
Packaging, Container Loading, and Export Logistics
Single fire doors ship in KD (knock-down) format as standard for export orders — door leaf, frame, and hardware packed separately. This is the format that maximizes container utilization and eliminates alignment risk in transit.
Container Loading Comparison
| Format | CBM per Set | 40HQ Loading |
|---|---|---|
| KD single fire door Standard | 0.18–0.22 m³ | ~160–200 sets |
| Pre-hung assembly (door + frame) | 0.35–0.45 m³ | ~80–100 sets |
Why KD Is the Default
KD is what most of our export buyers specify — the container economics are significantly better, and your installer fits the frame to the actual opening on-site, which eliminates any transit racking issue. Pre-hung is available for buyers whose end customers require ready-to-install product; the trade-off is roughly half the container loading efficiency.
Batch Traceability
Every carton carries a barcode linked to our production batch record. If there's a quality question on arrival, you trace the unit back to its production date, line, and inspection record.
Active Export Markets
We've shipped single fire doors to Los Angeles, Houston, Dubai, Singapore, Lagos, and Sydney. The documentation package is complete for customs clearance in all active markets.
Lead Times
25–35 days for standard catalog single fire doors from deposit confirmation. Custom configurations add 10–15 working days for engineering review and first-article approval.

Frequently Asked Questions
What is the difference between a single fire door and a double leaf fire door — and which should I stock?
A single fire door has one active leaf covering the full opening width (typically 700–1200mm). A double leaf fire door uses two leaves to cover wider openings (typically 1200–2400mm) and requires coordinated active/passive leaf hardware. For most distribution catalogs, single leaf is the volume SKU — it covers the majority of commercial openings, installs faster, and has lower hardware complexity. Stock single leaf in depth (FD30 and FD60 at minimum), then add double leaf for wide-opening applications.
What fire rating do I need for a single fire door in a commercial building stairwell?
In most North American and Gulf markets, stairwells in mid-rise commercial buildings require FD60 (60-minute integrity). Low-rise buildings and interior corridor compartmentation often accept FD30. High-rise stairwells and high-risk compartments (electrical rooms, server rooms) typically require FD90 or FD120. Always confirm with the local authority having jurisdiction (AHJ) — building codes vary by jurisdiction and occupancy type. Our NFPA 80 certification covers the US market; CE covers Europe and Gulf.
Can a single leaf fire door be fitted with a push bar (panic hardware) and still maintain its fire rating?
Yes, but the push bar must be fire-rated and listed to the same standard as the door. A non-rated push bar on a fire door voids the door's certification. We supply fire-rated push bar hardware (EN 1125) as part of the door package, tested and compatible with our CE-certified assemblies. For NFPA 80 markets, UL-listed panic hardware is required — we can source and integrate this on request.
What is the maximum custom size available for a single leaf fire door?
Standard range is 700–1200mm width × 2000–2400mm height. We can manufacture non-standard dimensions — widths outside this range and heights above 2400mm — through our custom engineering process. Send us your target dimensions; our engineering team will review for manufacturability and respond with a 3D rendering and quote. Custom configurations start at 100 units MOQ.
How do I verify that the intumescent seal on a single fire door is correctly specified?
The intumescent strip must be rated to the door's fire resistance class — an FD60 door requires an FD60-rated strip, not an FD30 strip. On our doors, the strip specification is documented on the production batch record and the strip is recessed into a machined channel (not surface-applied). When evaluating any fire door supplier, ask for the intumescent strip specification and the test certificate that covers it. If the supplier can't provide this, the door's fire rating is unverifiable.
What is your MOQ for single fire doors, and can I mix FD ratings in one order?
Standard catalog single fire doors: 50 units MOQ. Custom configurations: 100 units. You can mix FD ratings (FD30, FD60, FD90, FD120) within a single order as long as each line item meets the individual MOQ. For mixed orders below the per-SKU MOQ, contact us — we can often accommodate smaller quantities on existing production runs.
