What Hoffmann does
Hoffmann, Inc. is a fourth-generation, family-owned industrial design-build firm headquartered in Muscatine, Iowa, operating since 1914. The company specializes in the design, engineering, fabrication, and construction of cast-in-place reinforced concrete silos, concrete chimneys, steel stacks, and related bulk material handling equipment for industrial customers across the continental United States. Its core technical asset is a proprietary jumpform construction system that supports silos and chimneys ranging from 9ft to 112ft in diameter, complemented by a 70,000+ sq. ft. in-house fabrication facility with AWS-certified welders and barge, rail, and truck shipping access via the Mississippi River.
The company's product portfolio spans three integrated solution lines: Storage (concrete silos, steel bins via a Sioux Steel partnership, hopper tanks, engineered fabric hoop buildings, and bunker walls); Equipment (custom conveyors, bucket elevators, towers, catwalks, and dust suppression hoppers); and Stacks and Chimneys (ASME STS-1 compliant steel stacks and jumpform concrete chimneys). Supporting services include engineering and design, inspections and repairs to ASCE standards, and millwright/industrial installation work. The company reports having built over 600 silos nationwide and that approximately 50% of its business comes from repeat customers, with some relationships exceeding 30 years.
Hoffmann operates through direct project-based sales to enterprise industrial customers in power and utilities, cement, grain and agriculture, mining, and bulk commodity processing. Pricing is custom, quote-based, and project-specific, with no public pricing tiers. The company is privately held with no institutional funding, operating through four divisions (Hoffmann Storage, Silver Hawk Steel Fabrication, Airoflex Equipment, and Wolf Material Handling Systems) and currently led by fourth-generation owner and President Kristin Lee. Revenue is not publicly disclosed.
