What thickness of fireproofing coating is greater than suitable for steel structures?

Fireproof coatings with a thickness greater than 7mm are suitable for steel structures, which are usually categorized as thick fireproof coatings (7mm~45mm). The thick fireproof coating has the advantages of non-combustibility, non-toxicity, aging resistance, durability, etc. Its fireproofing principle relies on its own non-combustibility and low thermal conductivity to slow down the temperature rise of the steel and play the role of fire protection.

When choosing fireproof coatings, in addition to considering the coating thickness, it is also necessary to make comprehensive considerations according to the actual situation of the steel structure, fire resistance requirements, decorative effect, and economy. At the same time, ensure that the selected fireproof coating complies with the relevant standards and specifications to ensure the fire safety of the steel structure. In addition, attention should be paid to the construction quality of the coating and the control of coating thickness during the construction process to ensure the fireproof effect of the fireproof coating.
