Angle steel, like other steel products, is a metal with good heat - conducting properties and does not have inherent good fire resistance. When exposed to high temperatures, its mechanical properties, such as strength and stiffness, will gradually decline. However, through proper fire - resistant treatment, such as applying fire - resistant coatings, the fire - resistance of angle steel can be Uzlabots . Uguns - izturīgi pārklājumi var palēnināt siltuma pārnesi uz tērauda, saglabājot tā strukturālo integritāti ilgāku laiku ugunsgrēka gadījumā, kas ir būtisks, lai nodrošinātu ēku un konstrukciju drošību .
