Crucial, cost-effectice safety

Exposed steel structures enable exciting and effective design to be used in all areas of construction from factories to sports halls, hospitals to schools.

But if fire strikes, the potential for disaster is frightening. Within minutes unprotected steel can reach the critical temperature that causes it to lose stability and collapse.

SIGMA FIREBARR intumescent coating provides vital extra time. Time for people to escape.
Time that can allow fire fighters to save the building itself.

Intumescent coatings work by expanding in heat, from a very thin, lightweight coating into a thick, foam layer that insulates the steel and maintains its stability.
