ALUSTEP® F with aluminium honeycomb core and phenolic fibreglass skins.
Sandwich panels made with an aluminium honeycomb core and phenolic fibreglass are extremely light. Thanks to the low flammability of phenolic resin, this panel has a certified version which is used in shipyards, trains and transport in general. Alustep F obtained the IMO MED certification Mod. B and D for shipbuilding sector and HL3 for R10 (floors) and HL2 for R1, R2 (partitions, false ceilings) in the railway sector.
