What Rosenboom does
Rosenboom is a private US manufacturer of custom-engineered hydraulic cylinders, founded in 1974 by Lary and Viv Rosenboom in Sheldon, Iowa as a tool and die shop. The company designs and produces cylinders and full sub-assemblies (cylinders, hoses, attached fabrications) to OEM specifications, with engineering teams collaborating with customer engineering departments from concept through product rollout. It serves heavy-equipment OEMs across construction, refuse, agriculture, fire rescue, and transportation, and operates a proprietary JIT private delivery fleet to control logistics and eliminate freight damage.
The core technology stack combines LEAN cellular manufacturing, 30+ robotic welders (over 90% robotic weld completion), AWS-certified welding with a full weld certification lab (ultrasonic, dye penetrant, magnetic particle, macro etch/hardness testing), in-house friction welding, and a purpose-built industrial paint system handling 20 concurrent colors with wet-on-wet two-component primer and polyurethane topcoat. Every cylinder leaving production is 100% oil tested for leaks. Multiple production facilities are operated, with a $19 million Milford, Iowa expansion approved in May 2026 through Iowa's Business Incentives for Growth program to add 78 jobs. The company holds ISO 9001:2015 certification.
Rosenboom's commercial model is a sales-led B2B motion targeting enterprise OEMs under custom quote-based pricing and multi-year contracts, with hardware sales as the sole revenue stream. Marketing is primarily direct and relationship-driven, supported by a corporate website; no external funding, M&A, or institutional ownership has been disclosed, consistent with continued family ownership from its 1974 origins.
