PROBOND UltraFR® is one of the only Fire Resistant Signage Grade panels in the world

PROBOND UltraFR® is designed for where a fire-resistant panel with a Group1 BCA Classification is required for signage applications.*

The mineral core is designed to resist burning under extreme fire conditions and the external aluminium has a PPG FEVE Coating for extended outdoor durability designed to withstand the harsh Australian UV conditions. It is the highest standard of panel for all signage applications.

PROBOND UltraFR® acp panel sheet has a total thickness of 3mm and an aluminium skin thickness of 0.3mm. It is suitable for folding, grooving and CNC routing and can be guillotine cut or sawn using standard aluminium blades. Available in white, it offers exceptional flatness and rigidity. Ideal for both exterior and interior flat face signage, shop fitouts, and display applications, especially where fire-resistant properties are essential.
