Rust removal and painting of steel structures is a task that is easily overlooked by current steel structure contracting units and is also a weak link in the construction of steel structure projects. If this phenomenon is not corrected, it will have a great impact on the construction quality of the steel structure, because the quality of rust removal and painting will directly affect the maintenance cost of the steel structure during its future use, and also affect the service life, structural safety and occurrence of the steel structure project. Fire resistance time in case of fire (fire retardant coating). The ideological root cause of this phenomenon lies in the insufficient understanding of the importance of painting work by relevant personnel of the contracting unit, coupled with the lack of quality responsibility and even profit-seeking, which ultimately leads to frequent quality problems in painting projects. Therefore, supervision engineers must attach great importance to rust removal and painting work and conduct strict inspection and acceptance of each process. This is the basis and guarantee for ensuring the quality of steel structure painting. Regarding the coating quality of steel structure projects, the following work should be done: Strict acceptance of the rust removal quality of steel components according to the design requirements, inspection of the factory quality certificate of the coating raw materials, and the approval of the fire department for fire retardant coatings Prove that before painting, dirt, oil and other debris on the surface of the component must be thoroughly removed. Painting construction should be carried out in a dust-free, dry environment, and the temperature and humidity must meet the specification requirements. The number of coating passes and coating thickness must meet the design requirements. Damaged parts of the coating must be treated carefully to ensure the quality of the coating. Carefully check the coating adhesion and strictly conduct visual inspection and acceptance to ensure that the coating quality meets the specifications and standards.
