Intumescent
Coatings

Fire resistant coatings for structural steel designed to protect buildings and maintain structural integrity during a fire.

Intumescent Coatings for Structural Steel

Intumescent coatings are a specialised passive fire protection solution used to protect structural steel from the effects of high temperatures during a fire. These coatings expand when exposed to heat, forming an insulating layer that slows the rate at which steel heats up.

This delay is critical in maintaining the structural integrity of a building, providing valuable time for evacuation and emergency response. Intumescent coatings are commonly used where exposed steel is part of the architectural design, allowing both fire protection and visual finish to be achieved in a single system.

Bowsers provides professional application of intumescent coatings across commercial, industrial and infrastructure projects, ensuring all systems meet fire rating and compliance requirements.

What Our Intumescent Coating Services Include

All systems are applied in accordance with manufacturer specifications and project requirements.

Compliance & Fire Rating Requirements

Intumescent coatings must be applied to precise thicknesses to achieve specific Fire Resistance Levels. Incorrect application can significantly reduce performance and compromise building safety.

Bowsers ensures all intumescent coating systems are installed in accordance with Australian Standards and National Construction Code requirements. We work to detailed specifications and provide documentation to support compliance and certification.

Our team collaborates with builders, consultants and certifiers to ensure all fire protection systems meet project and regulatory requirements.

Frequently
Asked Questions

What are intumescent coatings?

Intumescent coatings are fire protective coatings that expand when exposed to heat, forming an insulating layer that protects structural steel.

How do intumescent coatings work?

When exposed to high temperatures, the coating expands and forms a char layer that slows heat transfer to the steel.

Can intumescent coatings be used on exposed steel?

Yes, they are commonly used on exposed structural steel where both fire protection and appearance are important.

Do intumescent coatings require maintenance?

They should be inspected as part of ongoing building maintenance to ensure the coating remains intact and compliant.
