Coratec sandwich panels for developers


We support you in the development phase with our know-how, engineering and prototyping. Together we work out solutions that are tailored to your specific requirements.

Are you looking for functional sandwich panels, with characteristics adapted to your specific application? As a developer and manufacturer of sandwich panels, we can meet your needs in terms of surface, strength, weight, fire protection, functionality, interfaces and coatings. You will receive individual pieces for your product development as well as serial production produced in a timely manner. With our expert knowledge, perfectly equipped infrastructure and short communication channels, we contribute to your success.

We process aluminum and GRP as outer layers as well as other materials upon customer request. Aluminum is available from stock in different colors and widths.

Our specialty is the production of sandwich panels with our own core material Coracel®, which is also integrated into our Corapan® products. From the initially granulate material, a PU cell structure similar to the structure of bones is formed during compression and curing.

Compared to other core materials, this results in the following advantages:

  • One panel, one core: Panels up to a format of 6,000 x 2,200 mm can be produced with one single core. Compared to panels with other core materials, this allows for perfect surface quality and highest strength.

  • Inlays: Because the material is granulated prior to compaction, inlays can be "poured in". This is efficient because the core material does not have to be milled separately and leads to a complete integration of the inlay with the best possible bonding capability to the core.

  • High bending stiffness: Sandwich panels with a Corapan core are particularly rigid.

  • Efficiency in production: The production of the core, integration of inlays and bonding with the top layer takes place in one single production step.

If your requirements are better met with other materials, we also process PET and XPS cores as well as aluminum and other honeycomb structures.

Create a multifunctional element with inlays from a simple sandwich panel. There are virtually no limits to the integration of inlays. They are usually used as reinforcements, cable ducts or fastening points for hinges and locks. However, more complex inlays such as heaters, cooling systems, lighting, vacuum cans, etc. can also be integrated.

We apply the non-slip coating on our balcony floors ourselves. We possess the experience, know-how and network for the development of new coatings as well as for the serial production of coatings. We can therefore offer both panels and the appropriate coating.

Do you need support in prototyping?

Short learning cycles are important to speed up product development. With our testing facility, we are able to produce prototypes and samples quickly and flexibly outside of current production runs. This allows us to support your development project as best as possible.

We take over the quantification!

Using our universal testing machine, we quantify the mechanical properties of sandwich panels such as bending stiffness, shear modulus, compressive strength and the pull-out forces of rivets or threaded sleeves. Please contact us, we will be pleased to advise you.
