Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams
ALUSTEP ® 300 - D is a lightweight composite panel with an aluminium honeycomb core 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 panel for example permits huge savings as far as weight and thickness of natural stones slabs, such as marbles and granite and mosaics are concerned. In this way, also the costs of these materials can be reduced.
