Why is Rust Prevention Treatment Necessary Before Applying Fire-resistant Coating to Steel Structures?

Rust prevention treatment on the surface of steel structures is the basic process of coating construction. The purpose is to create a favorable condition for the adhesion between the steel structure surface and the coating, while also improving the performance of the coating. The surface treatment technology in fireproof coating construction has received special attention, as it is the foundation and key link for achieving good results in the entire coating process.
