Midwest Steel & Iron Works, Metal fabrication facility in Denver, United States

Midwest Steel & Iron Works is an industrial complex in Denver made up of four buildings, including a two-story Art Deco brick office building and a large manufacturing hall on Larimer Street. The structures maintain the original layout and machinery from the factory's operating years.

Midwest Steel & Iron Works was founded in 1893 and was known for a time as Jackson-Richter Iron Works. Its four-building headquarters on Larimer Street served the company from 1923 to 1983. The office building dates from 1906, and its two-story Art Deco brick addition was designed by Denver architect Roland L. Linder in 1930. The complex was listed on the National Register of Historic Places in 1985.

The company was known for a time as the Jackson-Richter Iron Works, and its Larimer Street complex served as headquarters from 1923 to 1983. The 1930 two-story Art Deco brick addition was designed by Denver architect Roland L. Linder, a detail visitors can spot in the building's facade.

The complex on Larimer Street reopened in 2018 as a private event space after renovations, so it is not open for general public visiting. Access depends on the event being held there. The site is a four-building complex listed on the National Register of Historic Places in 1985, with two contributing buildings on 2 acres.

The shop building, put up in 1911 and enlarged in 1923, 1952 and 1967, still holds an original rivet forge from about 1925. Most of the firm's early machinery is gone, so this forge is the surviving piece of equipment to look for inside the complex.
