Norms

Fulfilling norms all along the guideline

Quality norms are created by specific demands determined by law, state of the art, the manufacturers and naturally the consumers themselves.

These four corner stones and their resulting norms are the foundation of the doitBau® selection. With them we create the requirements for an extensive product satisfaction.
