Since December 2003, it has been officially recognized by RAL - the German Institute for Quality Assurance and Certification.
The members are German and foreign providers of pipe fixing systems and the strengths of the Gütegemeinschaft Rohrbefestigung e.V. lies in its neutrality and it is under no obligation to any single producer.
The quality mark is given only to those products which fully meet its stringent requirements in accordance with RAL GZ-655. Products bearing the mark inspire trust in the customer who knows he can totally rely on them.
