Information in connection with the corona virus SARS-CoV-2

Due to the current development regarding the corona pandemic, we are confronted with new information, measures and provisions every day.

The German Federal Government has decided to slowly ease the safety measures, and so we too are taking the first cautious steps into normality.

Our sales representatives are on the road again visiting customers, observing the required precautions and current regulations. Of course, telephone or video conferences can still be held instead, if preferred.

AZ Armaturen GmbH remains your reliable partner even in these difficult times.

Stay healthy!
