Fire Resistance of Steel Profiles: Critical Factors for Building Safety
Steel profiles are the cornerstone of modern construction. However, at high temperatures loss of strengthis a critical issue in terms of fire safety. The right material selection and fire resistant coatings are used to ensure that steel profiles Even at temperatures above 600°C It ensures that the load-bearing capacity is maintained. As Samas Industrial, we offer fire resistant steel solutions that comply with European standards.
1. Behavior of Steel in Fire: Why Special Protection is Required?
- At 500°C steel, initial strength loses.
- At 750°C carrying capacity completely decreases.
- Expansion: Heated steel expands, creating a risk of cracks in joints with reinforced concrete.
Solution: Steel in case of fire at least 90-120 minutes using systems that will protect.
2. Fire Resistant Steel Profile Systems
A) Passive Protection Methods
| Method | How Does It Work? | Advantages | APPLICATION |
|---|---|---|---|
| Fire Resistant Paints | Creates an intumescent layer that expands with heat | Aesthetic, thin layer (1-3 mm) | Office buildings, shopping malls |
| Plasterboard Coverings | Wraps the profile with plasterboards | Economical, up to 120 minutes protection | Industrial buildings |
| Spray Coatings | Mineral based material is sprayed | Fast application, suitable for complex shapes | Steel carcass systems |
| Embedding in Concrete | Steel profile is placed in concrete | Provides structural integrity | High-rise buildings, bridges |
B) Integration with Active Systems
- Automatic fire extinguishing combined with steel carriers
- Heat sensitive alloys: Activates fire vents by changing shape at 300°C
3. Standards and Test Methods
Samas Industrial products pass international fire tests:
| Standard | Testing Method | Durability Period | Samas Product Performance |
|---|---|---|---|
| EN 1363-1 | Testing according to ISO 834 curve | R30-R120 | R90 (90 minutes) guaranteed |
| EN 13501 | Classification (EI 60/90/120) | EI 60/90/120 | EI 90 certified |
| UL 263 | ASTM E119 test protocol | 1-4 hours | 2 hour resistance profile |
4. Project-Specific Solutions: Samas Industrial Difference
- BIM Compatible Profiles: Fire resistance details are integrated into the digital model
- Hybrid Systems: Fire barrier solutions in steel + wood composites
- 3D Printed Protective Cases: Personalized protection for special geometries
5. Strategies for Cost Optimization
- Risk Analysis: Use EI 30 in low-risk areas and EI 120 in high-risk areas
- Composite Materials: Cost savings with special seals in fire passages
- Lifetime Cost: Protection systems provide -20 premium advantage in building insurance
Conclusion: Safe Buildings Begin with Smart Material Selection
The fire performance of steel profiles is decisive for the safety and insurability of the project. As Samas Industrial, we offer solutions at European standards.
