CORAPAN® AL 220 is our sandwich composite panel when extreme strength is required.

CORAPAN® AL 220 is a sandwich composite panel of the CORAPAN® product family with our in-house core, CORACEL®. CORAPAN AL 220 uses aluminum for the outer layers. The core is designed for high strength, making the product suitable for extreme loads.

CORAPAN® AL 220 offers the following advantages compared to alternative solutions:

  • Excellent stability:

    The core offers very high stability under compressive and shear loads.

  • 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.

  • Large and variable formats:

    Formats up to 6000 x 2200mm and any thickness between 15 and 40mm are available.

  • Durability:

    CORAPAN® AL 220 has a closed core and does not weather.

  • 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.

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