As automotive producers are placing increasingly quality demands on the surface area profile of electrolytic
galvanized strip, there is a growing need for steel producers to measure the surface waviness, in addition to the
surface roughness. thyssenkrupp Steel Europe AG has been using the waviness measuring system from
Amepa in an electrolytic coating line. This line is the first worldwide that measures the waviness along the
entire strip length and width inline during running production.
