Corahex®

CORAHEX® is our sandwich composite panel with aluminum honeycomb core, which we also produce extra wide and thick.

CORAHEX® is our sandwich composite panel with aluminum honeycomb core and aluminum outer layers. Aluminum honeycomb cores provide an excellent weight-to-strength ratio. CORAHEX is therefore a good choice when high stability at a low weight is a priority and insulation is not important.

CORAHEX® offers the following advantages compared to alternative solutions:

  • Special formats

    With our discontinuous production, we can also offer unconventional formats of max. 6000 x 2200mm and thicknesses between 10 and 40mm.

  • Special outer layers

    Our production process allows the production of sandwich composite panels with aluminum honeycomb core and special outer layers from other materials such as chrome steel. Suitable alloys or thicker outer layers are used for heavy duty applications. For sound insulation in interior construction, perforated aluminum outer layers can be integrated.

We produce formats, cut-to-size and edge finish according to your specifications. Find out more about our offerings on the pages on edge finish and outer layers.
