Sandwich panel specialists About us

The foundation stone for Coratec AG was laid in 1966 with the development of a material for space travel. Since then, we have been developing, producing and distributing high-quality sandwich panels and systems based on them for the construction, transport and industry sectors worldwide.


Coratec is a manufacturing company in Gunzgen, Switzerland, which develops its own products. The product range consists of high-quality sandwich panels and other products based on this technology. These are mainly used in the construction, transport and industrial sectors.

The customer and his projects are at the centre of our activities. We manufacture exclusively project-oriented according to customer specifications. Our consultants are flexible and quick to process your enquiries and implement your wishes.

We attach great importance to the highest quality. Our products are manufactured exclusively in our production hall in Switzerland. This gives us consistency and control for optimal quality.
