- The displayed HE 200 A example pairs a stated R 90 target with 585 °C critical temperature, 14 mm protection, and 96 minutes of resistance.
Field notes
The described workflow starts with a profile, steel grade, and exposed sides, then takes design forces and the required fire-resistance class. FireSolver says it accounts for instability cases, including buckling and lateral-torsional buckling, and can calculate protection thickness using the section factor. Its sample output is labeled HE 200 A · S355 and shows 96 minutes against a stated R 90 requirement.
