A company may only carry the RAL-GZ 662 Quality Mark (Gütezeichen) if it fulfils all the requirements of the RAL Quality and Inspection Regulations.
High-quality epoxy powder coatings prolong the service life and improve the products used to transport drinking water, waste water and gas (e.g., by preventing corrosion).
We therefore initiate independent audits to keep this quality level at a constant high. We empower our members and have established a loyal and sincere bond with each and every one of them.
Here you can find the manufacturers, products and coating materials worldwide that carry the RAL Quality Mark (Gütezeichen) of GSK, thus guaranteeing the highest standards.
