They are simply called sheet metal parts or they are directly referred to by the usual industry and commercial terms, such as cake plate, perforated plate, shaped piece or bent part. On a multi-level BOM, however, these descriptions are usually not found. Each part is named according to its function. There we are talking about the holding plate, basic bracket, auxiliary rail, reinforcing rib, clinker brick or simply the holder. But no matter what they are called - for us every piece of sheet metal is a high-quality stamped part, in which we incorporate our know-how and experience.
