What is the alternative to intumescent paint?


There are a few options to take into account for fire protection on structural steel, even though intumescent paint is a common choice. Depending on the needs, these substitutes may offer fire protection that is on par with or superior to intumescent coatings. The following are a few substitutes for intumescent paint:

Concrete encasement: When a structural steel element is encased or immersed in concrete or masonry, it serves as a common alternative for fire protection. In addition to being able to withstand high temperatures, concrete effectively blocks heat and flames.

Fire-resistant cladding is an alternative that can be applied to steel structures to provide external protection. It entails covering the outside of steel supports with specialty panels or coatings to make them fire resistant and stop flames from spreading.

Plasterboard made of gypsum or vermiculite is used internally on structural steel elements such as columns made of steel. They are a well-liked substitute for intumescent coatings because of their strong fire resistance and low thermal conductivity.

Endothermic materials are utilized in coatings and panels because they are able to absorb the energy emitted during combustion. They work well to control heat buildup in steel buildings by delaying it.

Water-based sprays known as "fireproof sprays" are applied to the surface of structural steel to form a thin coating that is resistant to high temperatures and prevents the spread of flames.

To determine the best fire protection system for a given application or environment, it is imperative to speak with an expert and take into consideration several aspects like cost, building codes, safety requirements, fire ratings, and aesthetics.
