In modern construction engineering, steel structures are widely used due to their high strength and construction convenience. However, problems such as easy corrosion and poor fire resistance seriously affect structural safety and service life. This paper focuses on the research of "integrated coating technology for anti-corrosion and fire protection of steel structures," aiming to propose a new coating system that can simultaneously meet the dual functions of anti-corrosion and fire protection. By analyzing the performance defects of existing coating materials, comparing the protective effects of different composite coatings with experimental data, the influences of material ratio, coating process, and environmental adaptability on the comprehensive properties of the coatings are discussed. The integrated coating using organic-inorganic composite base materials and added multifunctional additives has significant advantages in improving corrosion resistance and fire resistance limit, which can provide new ideas for the long-term protection of steel structures.
