Midwest Welding and Machine, Inc. started in 1944 in an old blacksmith shop near downtown Bozeman, MT.


2000 -  We became an AISC Certified Fabricator to SBD, later to the Building Standard.


2006 - The structural steel fabrication division of the company was purchased and this new entity became Midwest Steel Industries. (Midwest Welding and Machine, Inc. returned to their "pre-structural steel" name, facility, and specialties).


2014 - We changed our name from Midwest Steel Industries to Montana Steel Industries to eliminate confusion.

Montana Steel Industries is proud of our heritage and the hard working people that built that heritage. We continue that tradition with an incredible assembly of professional talent and fabrication equipment. Our team is dedicated to provide fabricated steel on time and error free.


Our desire is that your project has every chance to succeed. Our high percentage of repeat business is testimony to our successful efforts.
