Thurston’s advanced fire rated portable steel buildings have been independently tested to prove their outstanding fire resistance.

An independent analysis carried out by Warrington Fire Research Centre found that our Surefire fire rated buildings range can contain fire for a full 60 minutes – double the minimum requirement of 30 minutes under BS476. Despite maximum internal temperatures of 1100°C, the structural integrity of the unit remained intact.

Surefire also fully complies with building regulation requirements for fire resistance as well as the Joint Code of Practice on the Protection from Fire of Construction Sites and Buildings Undergoing Renovation.

Suitable for a wide range of uses, including site offices, mess rooms and storage, the all-steel Surefire range can be double stacked and is anti-vandal insurance certified, making our fire rated building range a market leader.

The robust construction of Surefire makes extensive use of non-combustible Galvatite steel, ensuring long-life and durability. Roof and wall cavities are insulated with non-combustible glasswool fibre, and floor insulation is available as an option.

Fire Rated Portable Steel Buildings – Typical external finish

A zinc-rich galvanic primer is applied to all external mild steel surfaces and weld areas. Fully galvanised panels are spray-coated with mid-grey semi-gloss fast enamel to BS4800 with trims, including skirting, jack legs and fascia, in contrasting dark grey to BS4800.

Fire Rated Buildings – Ease of use

Surefire fire resistant portable steel buildings have individually adjustable and removable telescopic jack legs to make levelling and double stacking easy.

A steel lifting ring welded to the top of each jack leg enables crane handling using four-leg slings and bow shackles to BS 6994. Heavier Surefire units are supplied with roof-mounted eye bolts instead of jack leg rings.
