Fire protected solid steel bars may behave differently from fire protected hollow steel sections in fire. The use of a specific protection system and its thickness should be based on a proven capabiity suitable to the application. It is necessary to generate a multi-temperature thermal analysis based on the fire testing of solid bars over a range of diameters. Consult the fire protection manufacturer for advice on the use of specific products. NOTE – ASFP Technical Committee agreed on 080513 to develop a specific ASFP fire test protocol for assessing the fire protection for solid steel bars and rods.
