【Fireproof Coatings】Thin fireproof coatings and cement-based fireproof coatings – which is better?

Which is better, thin fireproof coating or cement-based fireproof coating? In fact, there is no such thing as a better option between thin-coated and thick-coated fireproof coatings. These two materials are selected based on the usage environment and occasion, with comprehensive cost-effectiveness also taken into consideration. 1. Application environment: For load-bearing steel structures in general petrochemical and chemical plants, cement-based materials are preferred, mainly due to considerations regarding service life and overall efficiency. Especially when temperatures are below zero in the north, it is necessary to choose a cement-based version. Thin-coated types are generally organic coatings, which are prone to cracking and peeling under frost heave conditions. 2. For large civil steel structures and similar applications in the south, it is recommended to use low-coating materials. Because thin-coated materials are thinner than thick-coated ones, they have better decorative qualities. Thin-coating types are generally chosen for places such as high-speed railway stations and airports. When choosing thin-coating materials for outdoor use in the north, one must be cautious and check whether the materials possess low-temperature flexibility and crack resistance. Thin-coat coatings are more expensive, while thick-coat materials are cheaper. Therefore, choose the appropriate type based on the specific usage environment.
