CORAPAN® AL 220
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 own manufactured core, the CORACEL®. CORAPAN AL 220 uses aluminium for the face sheets. The core is designed for high strength, making the product suitable for use with extreme loads.
CORAPAN® AL 220 offers the following advantages compared to alternative solutions:
Excellent strength:
The core offers very high strengths in compression and shear.Customised inserts:
Due to our manufacturing process, inserts can be easily inserted. Inlays serve as reinforcement, fixing points, etc. Inlays turn a panel into a functional, customised product.Large and variable formats:
Sizes up to 6000x2200mm and any thickness between 15 and 40mm are available.Durable:
CORAPAN® AL 220 has a closed-pore core and does not weather.Unmatched surface quality:
The surface quality of the CORAPAN product family is unsurpassed in terms of flatness and freedom from defects. This quality is a result of our discontinuous manufacturing process, in which the core with the cover layers is compacted in the press and cured under temperature.
We manufacture formats, cuts, edge trims and inserts according to your specifications. Find out more about our range of products on the pages on inserts, edge trims and cover sheets.
