Lightweight elements for marine applications

Metawell® lightweight panels and components are perfect for the wide use in shipbuilding, because of their low weight, high bending strength, additional corrosion protection and minimal material thicknesses. Therefore Metawell® lightweight components are often used e.g. on cruise ships, ferries, luxury yachts and mega yachts. Compared with solid aluminium a weight saving of up to 80 % can be achieved.

The lightweight panels made of aluminium are specifically approved for shipbuilding. For the necessary tests the whole sandwich material was tested. The certificate MED/3.64 C Class Division (Marine Equipment Directive – Directive 2014/90/EU, also called IMO/SOLAS, wheelmark, EC-Type Examination Certificate) is available.

Metawell® is produced in Germany and is successfully and extremely versatile used in shipbuilding. With an experience of more than 30 years, we can assist you in finding a technically and economically useful solution – from the lightweight panel to ready-to-be-installed components.


  • Good corrosion resistance thanks to the use of suitable seawater aluminium alloys according to DIN and an additional primer
  • Easy processing by using commercial woodworking machinery and best practices of carpenters - both in the workshop or directly on board
  • Easy installation of mounting parts through e.g. glueing, screwing, riveting
  • Corrosion protection, also of the core
  • Individual surfaces by: digital printing, lamination, coating. On request powder-coatable panels can be offered
  • The material is suitable for interior design up to the C Class Division and also for the protected outdoor area
  • Certification according MED/3.64 C Class Division (Marine Equipment Directive – Directive 2014/90/EU, also called IMO/SOLAS, wheelmark, EC-Type Examination Certificate)
  • Longtime experience in the shipbuilding industry
  • Delivery of tailored panels and machined parts on request
  • 100 % recyclable

Wall linings

Large format Metawell® panels can be used on a ship as walls or wall linings. They can be integrated into any interior design with paints, digital printing, film-coating or HPL. Curved parts and parapet claddings are implemented with the easily formable Metawell® Aluflex. This enables custom interior designs for bars, lounges, theatres or discotheques with hardly any technical limitations.

Ceiling solutions

Large-sized ceiling elements with Metawell® aluminium sandwich panels require only a simple substructure. With the lightweight but dimensionally stable Metawell® aluminium panels, not only the standard frame design is possible, but also self-supporting suspended ceiling canopies, ceiling domes or curved ceiling domes can be realised easily.

Raised floors and platforms

To minimize assembly time and to extend the grid width of the substructure for raised floors, the formats of Metawell® aluminium sandwich panels are simply adapted. The Metawell® aluminium panel Alu hl 10-03-10 hl / H6 is used in areas that have higher requirements for the compressive strength of the panels.
