Founded in 1969 in Langenfeld by engineer Paul Fontaine, Fontaine Engineering und Maschinen GmbH (FOEN) designs and supplies equipment for continuous steel galvanizing lines, with particular expertise in air-knife wiping and bath equipment. The family-run company is now led by Paul Fontaine’s son Pascal and serves steel producers internationally from three locations, while also modernizing existing lines regardless of their original manufacturer. FOEN’s workshop fully pre-assembles and tests its equipment in-house before delivery, a distinctive step for installation and commissioning.
