Aluminium has a lower melting point than carbon steel. As this is commonly known within certain industries. We, as an aluminium helideck manufacturer, have been asked many times what happens to an aluminium helideck or helipad when the helicopter on top of it catches fire. We answer that our helidecks or helipads are either equipped with a DIFFS or have a Safedeck configuration. Both systems will extinguish any fire on a helideck within seconds, so nothing happens to the helideck. However, regardless of the firefighting systems, aluminium helidecks are equivalent to steel helidecks in structural integrity during a pool fire. To make this evident, we have conducted a pool fire test on a helideck mock-up with a simulated parked helicopter on the helideck.
The details of the test are:
