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:
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.
