Fire-Rated Door Manufacturer China — FD30, FD60, FD90, FD120 Factory Guide

Fire-rated doors are a critical component of passive fire protection systems in residential, commercial, and industrial buildings. China has emerged as a major global supplier of fire-rated doors, offering competitive pricing with internationally recognized certifications including CE (EN 13501-2), UL 10C, and BS 476.

This guide provides B2B buyers with a comprehensive overview of sourcing fire-rated doors from Chinese manufacturers: fire resistance ratings, construction standards, certification requirements, pricing, and factory selection criteria.

Fire Resistance Ratings: FD30, FD60, FD90, FD120

Fire-rated doors are classified by their fire resistance duration in minutes. The most common ratings are:

Rating	Fire Resistance	Typical Application	Standard
FD30 (E30)	30 minutes	Internal compartment doors, stairwells	EN 13501-2
FD60 (E60)	60 minutes	Escape routes, plant rooms, garages	EN 13501-2
FD90 (E90)	90 minutes	High-risk commercial, industrial	EN 13501-2
FD120 (E120)	120 minutes	High-rise buildings, warehouses	EN 13501-2

Note: European standards use "E" notation (E30, E60, etc.) while UK/Commonwealth markets use "FD" notation (FD30, FD60, etc.). Both refer to the same fire resistance duration.

Fire-Rated Door Construction

The construction of fire-rated doors must meet specific requirements to achieve the rated fire resistance:

Core Material

The door core is the primary fire-resistant element. Common core materials include:

• Mineral wool / Rock wool: Most common for FD30–FD60. Density 80–120 kg/m³. Provides both fire resistance and acoustic insulation.
• Vermiculite board: Used for FD60–FD120. Higher density provides longer fire resistance.
• Intumescent materials: Expand when heated to seal gaps between door and frame, preventing smoke and flame passage.

Door Skin

Steel fire doors use cold-rolled steel skins (0.8–1.2mm). Wood fire doors use fire-retardant treated (FRT) timber or MDF with steel or intumescent facing.

Frame and Seals

The door frame must be compatible with the door leaf to achieve the rated fire resistance. Intumescent seals are mandatory for all fire-rated doors — they expand at approximately 150°C to seal the gap between door and frame.

Hardware

All hardware on fire-rated doors must be fire-rated: hinges (typically 3 per door leaf), locks, closers, and any glazing must be tested as part of the complete door assembly.

Certification Standards for Fire-Rated Doors

Market	Standard	Test Method	Certification Body
European Union	EN 13501-2 / EN 16034	EN 1634-1	TÜV, Bureau Veritas, Intertek
United Kingdom	BS 476 Part 22	BS 476-22	BRE, Warringtonfire
United States	NFPA 80	UL 10C / UL 10B	UL, Intertek
Australia/NZ	AS 1905.1	AS 1530.4	CSIRO, Exova
China domestic	GB 12955	GB/T 9978	CCCF

For export to the EU, fire-rated doors must carry CE marking under EN 16034 (pedestrian doorsets with fire resistance characteristics). The CE declaration of performance must reference the specific EN 13501-2 classification (e.g., EI2 60-C5 for a 60-minute fire and smoke door with self-closing).

Prices include standard hardware (3 hinges, mortise lock, door closer for FD60+). CE test reports and certification documentation are available at additional cost (typically USD 500–2,000 per door type for third-party testing).

Key Questions to Ask Fire-Rated Door Factories

1. Can you provide original CE test certificates? Request the Declaration of Performance (DoP) and the test report number. Verify with the issuing notified body.
2. What is the scope of the CE certification? Ensure the certificate covers your specific door size, configuration (single/double leaf), and hardware specification.
3. Do you have UL certification for the US market? UL 10C (positive pressure) is required for most US commercial applications.
4. What is your quality control process? Ask about in-process inspection, finished product testing, and third-party audits.
5. Can you supply fire-rated glazing? Vision panels in fire doors require fire-rated glass (typically borosilicate or ceramic glass).
