Fire-Resistant Steel Framing Systems: Safety and Robustness in Building Compartmentation
2026-05-13
Fire-resistant steel framing solutions for maximum safety, efficient compartmentation, and high structural performance in buildings.
Fire-resistant steel framing systems play a fundamental role in passive fire protection in buildings, ensuring effective compartmentation of spaces and limiting the spread of flames, heat, and hot gases. These systems are widely used in fire-rated doors, fixed glazed partitions, and fire-resistant screens, making them particularly suitable for buildings where safety and structural robustness are key factors.
Steel naturally offers high mechanical strength and structural stability, characteristics that make it especially suitable for fire-rated applications. During a fire, steel systems maintain predictable and controlled behaviour, helping preserve the integrity of the compartmentation element throughout the required fire-resistance period.
Fire-resistant steel framing systems are developed using specially designed profiles and internal insulating materials capable of withstanding high temperatures without compromising the stability of the assembly. These systems are typically combined with fire-resistant laminated glass incorporating special interlayers that react to heat, forming a thermal barrier that prevents heat transfer and the passage of flames.
The performance of these systems is defined through standardised fire-resistance classifications obtained by laboratory testing in accordance with European standards. The most common classifications include EI30, EI60, EI90, and EI120, corresponding to the period during which the construction element simultaneously maintains:
- Integrity (E) – preventing the passage of flames and hot gases;
- Thermal insulation (I) – limiting the temperature increase on the side not exposed to fire.
Technical solutions with classifications E (flame containment) from 15 to 120 minutes or EW (flame containment and thermal radiation control) from 15 to 120 minutes can also be achieved.
One of the main advantages of fire-rated steel framing systems lies in the ability to combine high levels of fire resistance with structurally robust and aesthetically minimalist profiles. This feature makes it possible to create large fire-resistant glazed surfaces with excellent stability while maintaining transparency and visual continuity within spaces.
The main technical advantages of these systems include:
- High mechanical strength and structural stability, even under extreme conditions;
- Excellent performance in fire compartmentation solutions;
- Capability to create highly robust fire-resistant glazed openings;
- Compatibility with high-performance fire-resistant glass;
- Durability and long service life.
Due to their characteristics, fire-resistant steel framing systems are frequently used in hospitals, hotels, schools, office buildings, public facilities, and industrial buildings, where fire safety requirements are particularly demanding.
As with other fire-rated systems, it is essential that manufacturing and installation are carried out by certified companies, ensuring that the installed system matches the tested performance. Compliance with European standards EN 14351 and EN 16034, within the CE marking framework for fire- and smoke-resistant doors and elements, ensures that these systems meet the technical requirements for testing, production control, and traceability.
