ALUSTEP® 300 LIGHT, the lightest of the sandwich panels of the -STEP series, with an aluminum honeycomb core and fiberglass skins

STEP series panels are applied in the stone sector to lighten marble and natural stones, as a reinforcement and support structure for mosaics or in the restoration sector. Due to their lightness, these panels can be used in buildings interiors as a marble support for floors and worktops. In addition, they are used in boat and mega yachts interiors where lightness combined with high mechanical properties becomes a key point in this sector .

Technical features

ALUSTEP® 300 LIGHT is a sandwich panel with an aluminium honeycomb core and fibreglass skins impregnated with epoxy resin. It is the lightest of the -STEP series panels and is characterized by high bending resistance and good resistance to medium temperatures. The panels of the -STEP are purchased by art galleries as a support for their works. In particular, Disney has created some of its splendid mosaics using CEL Components panels.
