Advantages of the Quality Mark (Gütezeichen)

A company may only use the Quality Mark (Gütezeichen) RAL-GZ 662 if it has fulfilled all requirements of the Quality and Inspection Regulations. We therefore offer public utilities a sustainable solution for the corrosion protection of their supply networks. This includes:

Regular self-monitoring of the valves and fitting manufacturers
Third-party monitoring by an independent testing institute
Compliance with the high requirements of the Quality and Inspection Regulations ensures high quality and very high corrosion protection of the products
Products are extremely durable due to the excellent corrosion protection of the epoxy powder coating and quality-assured processing
