    Fire has represented a problem in steel structures, in addition, the NEC does not establish loads or time that the structures must withstand this phenomenon, therefore, this research was developed, which analyzes the susceptibility to fire with international standards such as the Eurocode of Carrocerías Cepeda, a company dedicated to the manufacture of car bodies in which the elements involved in its production are highly flammable and have a high probability of causing a fire. The research was developed through three phases, the first one where the linear analysis of the structure was carried out considering the aspects of the NEC, thus identifying the critical profiles under normal conditions. During the second phase, the temperature reached by the profiles that make up the structure was analyzed, reaching high temperatures, which directly affected the properties of the steel such as the modulus of elasticity and yield strength, decreasing its structural capacity and increasing the probability of collapse. For the third phase, Gypsum material was implemented as a protective measure, which improved the fire resistance of the structure. The results show that Gypsum is an excellent fire protection material as it significantly reduces the temperatures in each of the profiles from 713.82 to 168.12 degrees Celsius, in the case of the most critical profile. The structural capacity after the fire will depend on the amount of material placed inside the structure.
