Corapan® AL 85

CORAPAN® AL 85 is our sandwich composite panel, which sets standards in surface quality and form stability in vehicle construction.

CORAPAN® AL 85 is a sandwich composite panel of the CORAPAN® product family with our in-house core, CORACEL®. CORAPAN AL 85 uses aluminum for the outer layers. The core is light, so the product is ideally suited for use in vehicle construction.

CORAPAN® AL 85 offers the following advantages compared to alternative solutions:

  • One panel - one core:

    In contrast to the other panels available in the market, CORAPAN® AL 85 is made of one core piece up to a format of 6000 x 2200mm. This is unique and provides excellent surfaces and the best possible stability.

  • Unmatched surface quality:

    The surface quality of the CORAPAN® product family is unmatched in terms of evenness and absence of defects. This quality is a result of our discontinuous production process, in which the core is compacted with the outer layers in the press and cured under temperature.

  • Excellent form stability:

    Due to its excellent and long-lasting form stability, CORAPAN® AL 85 is often used for hatches.

  • Large and variable formats:
    Formats up to 10'000x 2'610mm and any thickness between 15 and 60mm are available.

  • Customer-specific inlays:

    Due to our manufacturing process, inlays can be simply inserted. Inlays serve as reinforcement, fastening points, etc. With inlays, the produced panel becomes a functional product, specifically tailored to the customer’s requirements.

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