CORAPAN® AL 220
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:
The core offers very high stability under compressive and shear loads.
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.
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.
