YK Doors Fireproof Door Frames: The Structural Foundation of Fire Containment Systems

As a premier manufacturer of passive fire protection solutions, YK Doors understands that a fireproof door is only as effective as its frame. Our 2025 line of certified fireproof door frames provides the critical structural interface between walls and doors, engineered to maintain compartmentalization integrity under extreme conditions. Designed to meet UL 10B, EN 1634-1, and BS 476-22 standards, these frames form the backbone of modern fire safety systems in commercial, industrial, and institutional buildings worldwide.

Engineering Excellence in Fireproof Framing Systems

Material Innovation and Construction

YK Doors’ fireproof frames utilize hot-dip galvanized steel (1.5-3.0mm thickness) with proprietary intumescent cavity fills that expand at 200-250°C, sealing potential gaps before critical temperatures are reached. Our multi-chambered frame profiles exceed the thermal break requirements of IBC 2025 while maintaining structural rigidity under positive pressure testing per NFPA 252.

The frames feature:

• Integrated smoke seals with EPDM gaskets for <3mm clearance (exceeding EN 1366-10)

• Adjustable anchoring systems for ±6mm wall tolerance

• Pre-installed hinge reinforcement plates rated for 1.5 million cycles

Performance Specifications

• Fire ratings: 30/60/90/120 minutes (tested to 1200°C)

• Standard sizes: Adaptable to door heights up to 3000mm and widths to 1500mm

• Acoustic performance: Up to 44dB reduction (when paired with appropriate doors)

Global Compliance and Market Positioning

The international fireproof framing market is projected to reach $2.3 billion by 2027, driven by:

1. North America:

   • UL 10C certification becoming mandatory for all commercial projects

   • Growing demand for hospital-grade frames with antimicrobial coatings

2. European Union:

   • EN 16034 harmonized standard implementation

   • Increased focus on thermal efficiency in framing systems

3. Middle East:

   • Civil Defense requirements for 120-minute frames in high-rises

   • Demand for sand-resistant coating systems

YK Doors maintains third-party certification from Intertek, Warringtonfire, and MPA Dresden, with test reports available for all regional compliance requirements.
