Fire protecting structural steelwork - Steelconstruction.info

It consists of steel beams and columns in which fire resistance is achieved by the inclusion of reinforcement between the flanges, held in position by concrete. Fire resistance periods up to 120 minutes is achievable on columns using this approach and 180 minutes on beams .

Unprotected Steel. Unprotected steelwork can reach temperatures of 550°C in a fire, where it then can lose its load bearing capacity and collapse. Building regulations and legislation demand fire protection to upgrade the fire resistance of buildings.

Fire Protection Products and Systems Structural Steel ...

Structural Steel Protection (columns & beams). There are a number of different products and systems which can provide a fire rating to structural steel. It must be remembered however that a tested system must be used and in the case of structural steel the test must be performed on a loaded structural element.
