Steel Buildings & Fire Resistance
Fire Resistance in Steel Buildings – Safety Built In
At Steel Build Masters, we can design and supply fire-resistant steel buildings engineered for maximum safety, durability, and compliance. Whether you're constructing a cold rolled steel shed or a large-scale industrial unit, our structures are built to withstand fire exposure and reduce risk—protecting both property and people.
Cold Rolled Steel Buildings – Fire Performance
Cold-formed steel is inherently non-combustible, making it an ideal material for fire-safe construction. When used as the primary frame in combination with single skin or composite cladding systems, it offers exceptional fire resistance and structural integrity.
Key Fire Safety Benefits:
- Cold rolled steel does not contribute to fire load or spread
- Fire resistance ratings of up to 120 minutes achievable with fire casing
- External cladding and internal linings (e.g. gypsum or fire boards) enhance protection
- Significantly lower combustible content than timber or traditional builds
- Reduced fire risk during construction due to prefabrication and minimal on-site cutting
- Potential for lower insurance premiums and improved building longevity
Single Skin Steel Cladding – Class A Fire Resistance
Our single skin steel cladding systems are designed for high fire integrity and are commonly used in both industrial and agricultural applications.
Key Features:
- Non-combustible with up to 4 hours fire integrity
- Achieves Class 1 surface spread of flame (Euroclass B)
- Rated AA to BS 476-3:2004 and B roof (t4) to BS EN 13501-5
- Easily repairable after minor fire damage
- Used as the external layer in our twin skin systems for enhanced protection
Composite Cladding – Tata Steel Trisomet® & Kingspan KS1000 RW®
We only specify high-performance composite cladding systems from trusted manufacturers like Tata Steel and Kingspan—leaders in fire-rated steel panel technology.
