Description
Trafalgar Corex for steel beam and purlin penetrations is designed to maintain the Fire Resistance Level (FRL) of fire-rated walls and floors where structural steel elements pass through.
Unprotected steel penetrations can compromise fire compartmentation by allowing heat transfer between compartments, increasing the risk of system failure during a fire.
Why Steel Penetrations Need Fire Protection
When steel beams or purlins penetrate a fire-rated barrier:
- Heat transfers rapidly through the steel
- The insulation (I) rating of the FRL can be reduced
- Fire-rated walls or floors may fail prematurely
To maintain compliance with the National Construction Code (NCC), these penetrations must be treated using a tested passive fire protection system.
Corex Solution for Steel Penetrations
Trafalgar Corex fire-rated board is used to encase steel members for a specified distance on either side of the fire-rated barrier.
This solution:
- Reduces heat transfer through steel penetrations
- Helps maintain the required FRL performance
- Supports compliant fire compartmentation
Compliance and Installation
Corex systems for steel penetrations should be installed in accordance with:
- NCC requirements
- Relevant AS1530.4 and AS4072.1 fire test reports
- Applicable installation guidelines and system approvals
This ensures a reliable and compliant passive fire protection solution for structural steel penetrations.
