Structural collapses during industrial fires often trace back to improper steel selection. Our AISI 310 hexagon bars maintain strength at 1000°C, proving vital for cement plant kiln liners. For emergency exits in chemical plants, fire-rated flat bars with intumescent coatings withstand 2-hour blaze exposure. We recently helped a power plant retrofit boiler supports using chromium-nickel round bars that reduced thermal expansion mismatch by 40%.
