Tikkurila Intumescent calculator for steel allows you to select the required dry film thicknesses in mm of Fontefire ST 60-1 according to the valid European Technical Assessment (ETA). The selection is based on critical temperature and time (fire resistance classification) with either a known or unknown section factor (Hp/A). If the section factor is unknown, the calculator gives the option to calculate it from a selection of common steel structures.
