RASTAL received DIN ISO 9001:2008 / EN 29001 certification as long ago as 1994 and has since then practised consistent Total-Quality-Management, oriented toward customer satisfaction as top priority. Product quality, workforce and service quality as well as creative know-how are the pillars of this Quality Management. The quality of products and services is continually monitored and evaluated in all departments of RASTAL.

Two outstanding examples of RASTAL quality are High Quality Glass, specially created for hospitality-sector use, and computer-controlled decoration monitoring . RASTAL Design is a byword for top quality too. This is confirmed by numerous awards received in Germany and abroad.
