metallstenderer

Metallstenderer is a historical or obscure term found in some German-language industrial texts to denote either a person skilled in finishing metal surfaces or a piece of equipment used in metal finishing. The exact meaning varies between sources; some describe a metallstenderer as a craftsman who applies protective coatings, patinas, or decorative finishes to metal parts, while others treat the word as a designation for a machine that assists in stiffening, straightening, or tempering metal sheets during fabrication. The term appears in late 19th- and early 20th-century catalogs and trade writings, but does not appear as a standard term in modern metalworking lexicons.

Etymologically, metallstenderer is composed of metall- (metal) and a suffix akin to -stenderer, possibly derived from a verb meaning to render, stiffen, or stabilize. Because sources disagree on the precise role, the term is often encountered in archival material rather than contemporary manuals.

In current practice, metallstenderer is rarely used; when encountered, it is typically within historical discussions of metal finishing techniques or in translations of older industrial texts. Contemporary equipment and processes for metal finishing use terms such as coating, plating, patination, tempering, and straightening, rather than metallstenderer.
