Our certificates



mobil Kunststoffprofile has recently changed its overall appearance. The biggest change is the switch to the colour blue, which is now used for our company’s entire communications. It sends a clear message.

Lukas Lang, the previous division manager of mobil Kunststoffprofile, takes over the management of mobil Kunststoffprofile AG.
