English to French Tech/Engineering Architecture

Scrollwork is an element of ornamentation and graphic design featuring spirals, which resemble the edge-on view of a rolled parchment scroll. They were often made using a scroll saw. "Scrollwork" is today mostly used in popular language for two-dimensional decorative flourishes and arabesques of all kinds, especially those with circular or spiralling shapes.

j'ai trouvé "rinceauxe" mais je ne suis pas sûre qu'il s'agisse d'un équivalent exact.
