In the UK, fire-resistant paint is commonly applied to steelwork to enhance the fire resistance of structures. Specifically, intumescent paint is widely used, reacting to heat by expanding and forming a protective layer during a fire. This barrier delays structural failure.

Exposed steel work could lose up to 40% of its load bearing strength when it reaches a temperature of 500°C. Fires may reach temperatures of up to 800°C, when exposed to fire for a prolonged period time. 

Key considerations include compliance with regulations, collaboration with fire safety professionals and consultation with local building control authorities. Architects, engineers and building owners should ensure proper application and adhere to standards to enhance fire safety in steel structures.
