- • No edge delamination
- • Smooth appearance
2 Stile & Rail Construction
Steel face panels mechanically locked to vertical stiles and horizontal rails for reinforced structural integrity.
Advantages
- • Maximum impact resistance
- • Heavy-duty applications
- • Edge damage resistance

Installation & Compliance
Proper installation is critical for fire door performance
Critical: Fire-rated door assemblies must be installed per NFPA 80 and manufacturer instructions to maintain fire certification. Improper installation voids the fire rating. Fire doors must be installed by qualified personnel familiar with NFPA 80 requirements.
Frame Installation Steps
Verify Opening
Confirm rough opening dimensions match frame requirements
Set Frame
Position frame plumb and square in opening
Anchor Frame
Secure with minimum 3 anchors per jamb
Grout Frame
Fill with approved grout or mineral wool
Seal Perimeter
Apply fire-rated caulk at frame-to-wall junction
Door Installation Steps
Verify Door/Frame Match
Confirm door size matches frame with proper clearances (max 1/8" sides, 3/4" bottom)
Install Hinges
Mount hinges to frame using all screws. Ball bearing, steel hinges required
Hang Door
Lift door onto hinges. Verify proper swing and clearances
Install Hardware
Mount fire-rated lockset, closer, and other hardware per manufacturer instructions
Install Seals
Apply intumescent seals and smoke seals if not factory-installed
Adjust & Test
Adjust closer for proper latching. Verify positive latching and self-closing
NFPA 80 Clearance Requirements
| Location | Maximum Clearance |
|---|---|
| Hinge edge | 1/8" (3.2mm) |
| Lock edge | 1/8" (3.2mm) |
| Top edge | 1/8" (3.2mm) |
| Meeting edges (pairs) | 1/8" (3.2mm) |
| Bottom edge | 3/4" (19mm) |
| Undercut with threshold | 3/8" (9.5mm) |
Excessive clearances compromise fire rating. Doors with clearances exceeding limits must be replaced or modified.
Fire Door Inspection Checklist
Per NFPA 80, fire doors require annual inspection. Key items include:
Common Installation Issues
| Problem | Cause | Solution |
|---|---|---|
| Excessive clearances | Improper door/frame sizing or settling | Install intumescent strips or replace components |
| Door doesn't latch | Closer adjustment, strike misalignment | Adjust closer force, realign strike |
| Frame not grouted | Installation oversight | Grout frame per manufacturer instructions |
| Non-rated hardware | Substitution of specified hardware | Replace with UL listed fire door hardware |
Euwoo provides installation instructions with every order. Technical support available for installation questions.
Frequently Asked Questions
Common questions about steel fire-rated doors
What fire rating do I need for my application?
Fire door ratings are determined by building codes based on location and occupancy type. Common requirements: stairwells typically need 60-90 minutes, corridor walls 20-60 minutes, and hazardous areas 60-90 minutes. Consult your local building code or fire protection engineer for specific requirements.
What's the difference between UL, BS, and EN fire door certifications?
UL 10C is the North American standard used in the US and Canada. BS 476-22 is the British Standard accepted in UK, Middle East, and Commonwealth countries. EN 1634-1 is the European harmonized standard for CE marking. Euwoo doors are certified to all three standards, allowing global compliance.
Can fire-rated doors have glass vision panels?
Yes, but with limitations. Vision panel area is restricted by fire rating: up to 2580 cm² for 30-minute doors, down to 645 cm² for 90/120-minute doors. Glass must be fire-rated ceramic or intumescent gel type. Larger glazing areas reduce the achievable fire rating.
Do fire-rated doors require fire-rated frames?
Yes, a fire-rated door assembly includes the door, frame, and hardware - all must be fire-rated and labeled. A 90-minute door requires a 90-minute frame and listed hardware. The assembly's fire rating is only as good as its weakest component.
What hardware is required for fire-rated doors?
Fire doors require: (1) fire-listed hinges - minimum 3 steel or stainless ball bearing hinges, (2) fire-listed positive-latching lockset, and (3) self-closing device (door closer). All hardware must be UL or BS listed for fire doors. Panic hardware, coordinators, and other items must also be fire-listed.
How do I maintain fire-rated doors?
Per NFPA 80, fire doors require annual inspection covering: door closes and latches properly, clearances within limits (max 1/8" sides, 3/4" bottom), seals intact, hardware operational, no holes or damage, labels readable. Keep doors clean and hardware lubricated. Never prop open fire doors.
Can fire doors be modified in the field?
No. Field modifications such as cutting, drilling additional holes, or adding non-listed hardware voids the fire rating. Any modifications must be made by the manufacturer and re-labeled, or the door must be replaced. Minor adjustments to closer tension are acceptable.
What is the difference between fire-rated and smoke-rated doors?
Fire-rated doors prevent fire spread for a specified time period. Smoke-rated doors (per UL 1784/NFPA 105) also limit smoke infiltration through gasketing and tight clearances. Many applications require both - a door can be fire-rated with smoke rating added. Smoke ratings are designated 'S' on the label.
What gauge steel should I specify for fire doors?
18 gauge (1.2mm) is standard for most commercial applications. 16 gauge (1.5mm) is recommended for heavy-traffic areas, exterior applications, or doors wider than 4 feet. 14 gauge (1.9mm) is used for maximum security or industrial abuse. Gauge selection doesn't affect fire rating but impacts durability.
What is the lead time for steel fire-rated doors?
Standard lead time is 15-30 days depending on quantity, specifications, and certification requirements. Expedited production is available for urgent projects. Large orders may require additional lead time. Contact Euwoo for specific delivery timelines.
