Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams

Alustep 500 light

ALUSTEP® 500 LIGHT is a sandwich panel with a core in aluminium honeycomb faced with fibre glass impregnated with epoxy resin.

This panel offers unique characteristics since it combines lightweight with high mechanical properties. The application of this panels for example permits huge savings as far as weight and thickness of the slabs of natural stones, such as marbles and granite and mosaics are concerned. In this way, also costs can be reduced.
