Hoffmann Inc

Hoffmann, Inc. is an Iowa based design-build firm, conducting business throughout the continental United States since 1914. Through our vast history and experience, we are a nationally recognized leader in the design and construction of cast-in-place, reinforced concrete storage silos and chimneys.

In the 1970s, Hoffmann expanded its customer base and began building cast-in-place reinforced concrete storage structures with increased diameters. These larger-diameter storage silos were constructed using the jumpform technique. Jumpform construction also became an efficient method for building industrial concrete chimneys.

Several factors led Hoffmann to the fabrication and installation of steel stacks. First, Hoffmann began offering fabricated steel items as an added service to our customers of concrete silos and chimneys. Second, we were constructing concrete chimneys in the same industries requiring steel stacks. Hoffmann now supplies steel stacks in a large variety of configurations. Design, fabrication, and erection services are offered for any size of steel stack required for domestic use or export.
