Guide to Structural Steel Fire Protection

Intumescent steel coatings protect steel from reaching structural failure temperatures and with steel protection from Nullifire these will maintain structural stability for up to 120 minutes, giving the emergency services time to evacuate people from the structure and stop the fire.

Our products have been exhaustively tested both in our own laboratories but also to national and international standards in independent test houses across the globe, offering the ability to match several requirements. 

Plus, all our intumescent steel coatings have been formulated with our unique patent traceability technology – Optifire+, offering a guaranteed source of quality and right specification to architects and main contractors at all stages of construction.

We offer the complete steel protection system for fire protection and decoration of structural steel. Our intumescent steel coatings have been engineered for compatibility with primers and topcoats, some from our sisters group companies, namely Carboline.

Nullifire's Complete Steel Protection System

The SC ranges...

Water based Intumescent Steel Coatings (SC800 range)

Nullifire pioneered water based technology, which gives a smooth finish in a faster time than other methods. Given the environmental benefits of water-based coatings then these products are now the preferred choice among specifiers and applicators alike.

Solvent based Intumescent Steel Coatings (SC600 range)

For when environments are semi-exposed then solvent based products still provide an answer in obtaining an excellent finish in a reasonable time frame.

Hybrid Intumescent Steel Coatings (SC900 range)

These unique technologies have been developed to provide faster cure times without multiple coats, while still delivering the same level of fire protection and ratings. These are only available through Nullifire's approved applicators.

Manufactured by CPG Group companies…

We’re very meticulous and rigorous when selecting and advising the appropriate primers for the full steel protection system.

These have been tested and proved that work in harmony with our protective intumescent steel coatings and can be specified together with the confidence that they will perform both in application and in the event of fire.

Topcoats are the final element, designed to make the finished steel work look good, but also to protect the intumescent steel coating underneath.

At Nullifire we can advise and provide you with the right topcoat for our complete steel protection system from our sisters group companies. We’ve ensured that the topcoat is compatible with the intumescent steel coating.
