Steel structures are only as strong as their weakest link when engulfed in flames. They rapidly deteriorate when exposed and subjected to extreme heat during fires. Effective steel fireproofing helps fortify buildings’ structural bones against destruction and collapse by shielding steel with heat-resilient materials. Keep reading to learn more about keeping buildings safe through noncombustible and fire-resistant solutions.
Exposed Steel’s Fire Risks
When fires occur, steel buildings are highly vulnerable. Once temperatures exceed 400°C, steel rapidly loses over half its strength. Additionally, stability declines dramatically, which can result in sudden buckling and twisting of steel members.
Consequently, progressive collapse of the entire building may happen when structural failure spreads horizontally and vertically through a building. Robust fireproofing helps maintain steel integrity even when severely heated and provide ample time for safe evacuation.
How Steel Fireproofing Prevents Building Collapse
Quality steel fireproofing insulates steel thermally to maintain its critical load-bearing function despite raging fires. Dedicated fireproofing materials shield steel members to safely endure over 1000°C for hours without failure. Comprehensive fireproofing across all structural members is vital. This extra structural resilience provides precious additional evacuation time while containing fires.
Intumescent Paints Lead Fireproofing Innovation
Various steel fireproofing solutions exist, but intumescent coatings lead the way in terms of performance and aesthetics. Some of their key advantages include:
- Ease of Application
Intumescent products can be easily applied, like ordinary paint, for faster construction and lower labor costs. Their durability also reduces maintenance.
- Unparalleled Fire Resistance
Intumescent coatings expand when heated to produce a rugged insulating char layer up to 50mm thick, offering unmatched fire resistance over 4 hours.
- Preserved Steel Aesthetics
Unlike spray-on products, smooth intumescent coatings beautifully preserve the visual appeal of structural steel before and after exposure.
Other Fireproofing Techniques:
- Rigid Board Systems – Cement or gypsum boards resist fires for more than four hours. Offer added insulation despite taking up space.
- Spray-Applied Fire Resistive Materials – Involve spraying low-density insulating fibers or cementitious compounds onto steel. Efficiently limit heat transfer but contain hazardous substances.
- Concrete Encasement – It can cover steel in concrete to achieve excellent fire resistance.
- Fire-Rated Blanket Systems – Flexible fiberglass/mineral wool blankets wrap steel members. They allow quick installation and acoustic damping but require protection from damage.
Protecting Industrial Infrastructure
Industrial environments contain heightened fire risks requiring customized steel fireproofing integrated with active fire suppression systems. Durable solutions resistant to oils and extreme temperatures are preferable. Strict inspection, maintenance, and upgrade policies must be implemented over the facility’s lifetime.
