The FALA plant is easily accessible on Autobahn 7 (Germany).
Take the 54-Großburgwedel exit and drive towards Isernhagen HB.
There, turn right into the business park (Kupferstraße). Turn left into Eisenstraße, then right into Nickelstraße. After you've turned into the next street on the right (Chromstraße), you'll find Stahlstraße on your left; the FALA plant is on the right-hand side.
