M A Metal was established in 1946 as a small-scale, local metal stamping company, and it has since grown into a flexible, diversified metal forming and machining enterprise serving regional and international customers from a variety of industries.

Fred Stadler bought Midwest Art Metal in 1992 and changed the name to M A Metal; in August, 2015 NuMA Group Inc. inquired MA Metal. Through facility modernization, new equipment investments, and ISO 9001 certification, M A Metal has become a trusted leader in precision stamping and forming.


At M A Metal we have earned our reputation as a leader in quality. Here are just a few awards and recognitions we’ve received from vendors, municipalities and others who have recognized our commitment to continuous improvement.
