Why is it said that a non-professional team can't do a good job with the application of fire-resistant coatings for steel structures? Let's delve into this in detail by our editor.
Fire-resistant coating for steel structures is a type of fire safety material, where the quality of application directly affects its performance and fire safety. Based on domestic and international experiences, to ensure the quality of spray application, Article 3.1.1 of the "Technical Specification for the Application of Fire-Resistant Coating for Steel Structures" clearly stipulates that the fire-resistant spray protection for steel structures should be applied by a professional construction team that has received training and is qualified.
Due to some construction units cutting costs or seeking personal gains, they hire painters or organize personnel to apply fire-retardant coatings. This issue accounts for about 25% of the cases. For instance, the steel beams and columns of a certain center, the load-bearing structures within the ceiling of a company, and the load-bearing trusses of a large shopping mall's skylight well—all these fire-resistant coatings were applied by non-professional teams. Because they lack the necessary spraying techniques, the coatings were applied unevenly, some too thick and others too thin, resembling the way an old woman would draw eyebrows—here a stroke, there a stroke. This not only fails to meet the regulatory requirements but also looks unattractive. It is crucial to pay attention to this.
Fire-resistant coatings and spray thickness for steel structures are applied based on design requirements and technical specifications of the fire-resistant coatings. Once the spray layer peels off or is damaged, it will affect the fire resistance of the steel structure. Therefore, everyone must find a legitimate manufacturer to carry out the construction to ensure the quality of the project.
