Fire-resistant coating for factory building steel structures
Thread Content
Dear marine friends, does anyone know approximately how many kilograms of fireproof coating are used per square meter for steel structures (thick-type, thin-type, ultra-thin-type)?
Generally, three to four coats of anti-rust paint are applied: one coat of anti-rust primer, one coat of intermediate anti-rust paint, and one to two coats of topcoat. The thickness is usually around 0.35–0.5 mm; you can calculate it based on the specific density.
There is a method for calculating the amount of fireproof coating to be used; it seems to be mentioned in the chemical process design manual. The original poster can take a look there. Design institutes should have these books.
It is just a range, which is related to the actual construction conditions and the materials supplied by the manufacturer.
It depends on your fire resistance rating; the fire resistance thickness varies for thin and thick types, so it’s necessary to calculate the specific area.
This allows the required fire protection area to be provided to professional fire protection contractors. As for thin fireproof coatings, the thickness required for applying different products varies; as long as the product is **certified**, the weight per unit also differs depending on the product, generally ranging from a few tons to several dozen tons
