Made from a 4.8 mm thick 7-layer material all the way to the edge, it allows for edge-to-edge frying. The pans are designed in such a way that a non-stick coating is no longer necessary. When the pan is hot enough, you only need to reduce the heat by half, and the pan will take care of the rest on its own. Thanks to the surface treatments (Silvinox or Brinox) and the shape, these pans are very easy to clean.
