How do steel intumescent coatings work?
Steel is a powerful, durable, long-life structural framework solution that maintains its structural integrity long-term, so fireproofing may not seem necessary. However, when exposed to fire, steel can weaken, buckle, distort, and, in the worst-case scenario, reach its melting point, losing its load-bearing capacity and causing structural collapse.
When subjected to extreme heat, the intumescent coating expands, forming a thick, insulating char layer. This char acts as a low-conductivity, insulating barrier, protecting the underlying material from fire’s extreme temperatures. Intumescent coatings delay the increase in steel’s temperature during a fire to provide crucial time for evacuation, firefighting, structural stability and potential protection of property.
