The coating of all parts shall be preceded by faultless, specialised pre-treatment. The quality regulations of Gütegemeinschaft für die Stückbeschichtung von Bauteilen e.V. [Quality association for the piece coating of building components], Franziskanergasse 6, 73525 Schwäbisch Gmünd, shall be observed or coatings shall be applied according to the acquisition of the quality mark for coatings on architectural aluminium applied by wet and powder painting (issued October 1995) by Qualicoat Zürich, CH-8027 Zürich.
