About Ateco Services AG

Ateco Services AG is a globally active Swiss service provider for cleaning, maintenance and surface finishing services with a focus on stainless steel and aluminum components. Core competencies include passivation of new systems, derouging, deblacking, repassivation, chemical pickling, decalcification as well as stationary and mobile electropolishing. At the Unterentfelden plant, anodizing, coloring processes (chemical and electrolytic, Colinal© 3100) and hand-grinding contract work are also performed; parts up to a length of 6000 to 7000 mm are processed. The processes follow standards such as ASTM A380, ASTM A967, ASTM B912 and ISO 7599. Customers come from the pharmaceutical, chemical and biotech industries, food technology, medical technology, plant engineering, semiconductor manufacturing as well as architecture and construction. The processes are ISO 9001 certified, documented in a GMP-compliant manner and carried out with complete traceability; proprietary chemical brands (Diru) are patented.
