Midwest Steel & Iron Works was a metal fabrication company based in Denver, Colorado.
The company's headquarters on Larimer Street in Denver includes an Art Deco office building and consists of a four-building complex that is itself considered a historic industrial site.
[2][3] Among other works, the company manufactured the four Big Thompson River bridges in Estes Park and Loveland, Colorado, all of which are listed on the National Register of Historic Places.
While most of the firm's early machinery no longer exists, the shop contains an original rivet forge from circa 1925.
[1] In 2018, following a period of renovations, the building was reopened as a private event space.
