The ICC ES Report says that the coating can be good for a 4 hour rating on steel. Now that's saying something if it can do that. I can see where deputy inspection is a good idea. The odds of a residential application are slim. I wonder what the expense is.mtlogcabin said:intumescent paint does provide a thermal barrier. That is how it works. When steel looses 60% of its yeild strength it is considered a structural failure. That can happen at a low tempeture than wood. http://www.icc-es.org/reports/pdf_files/ICC-ES/ESR-1092.pdf
I learned something today. Thanks.Phil said:When heated, intumescent paints expand to provide a thermal barrier that protects the steel.
Better than boxing it in with Gypbd.globe trekker said:Painting the reclaimed steel beam with a generous coating of an intumescent coatingprobably won't provide the "aesthetic" look that is desired by the owners.
