In choosing a Betonbau aluminium door, you have selected a secure solution that will effectively protect your technical building against forced entry and reliably resist pressure loads and stress such as encountered as a result of technical interference (e.g. accidental arcing).
High-strength, weather-resistant materials carefully machined in our own metal production facility ensure that the outlay for care and maintenance is kept to a minimum
