About the company
Hader-Seitz Inc., a subsidiary of Hader Industries Inc., manufactures hydraulic components and actuator assemblies for defense logistics and military vehicle production as a small business prime contractor (86% of recent awards) and as a subcontractor to major defense primes. The company is headquartered in New Berlin, Wisconsin, and competes across full-and-open and small business set-aside categories, with roughly half its prime awards designated as Total Small Business set-asides and the remainder in open competition.
Hader-Seitz's capability portfolio centers on actuating cylinders, actuator assemblies, and fluid power transmission components for defense vehicle maintenance, repair, modernization, and production. Recent prime work includes a $214,896 Total Small Business delivery order from Army Contracting Command Warren (awarded January 2025) for 44 cylinder assemblies supporting military vehicle platforms, a $97,865 Total Small Business purchase order from Defense Logistics Agency Land and Maritime (December 2023) for 185 actuating cylinders, and a $100,167 small business set-aside order from DLA Land and Maritime (June 2023) for 197 actuating cylinders. The company holds multiple indefinite delivery contracts with Army Contracting Command Detroit Arsenal and the General Services Administration, with eight task orders under IDC DAAE0703DN068 carrying $3 million in combined potential value.
Customer concentration is heavily weighted to Army and defense logistics operations. The top five customer agencies account for 94% of awards, led by Defense Logistics Agency Land and Maritime (53 awards, $1 million combined potential value) and Department of the Army Materiel Command Contracting Command Detroit Arsenal (26 awards, $3.9 million), with Department of the Army (16 awards, $2.5 million), Army PEO Ground Combat Systems (18 awards), and general Defense Logistics Agency (9 awards) rounding out the active set. The dollar rankings diverge slightly — Detroit Arsenal anchors the potential-value tier while DLA Land and Maritime leads in award count — reflecting a mix of higher-value vehicle production work and smaller-dollar logistics replenishment orders. Across all federal customers, the company has generated $11.1 million in combined potential value and $12.2 million in obligated dollars (110% of potential value, indicating overruns or supplemental awards).
Activity has remained stable, ranging from seven to eleven awards per year since 2019, with ten awards in 2025 year to date. In its subcontractor role, Hader-Seitz supplies hydraulic components and materials to BAE Systems Land & Armaments L.P. for multiple combat vehicle production and sustainment programs, including the Bradley A4 follow-on production (M2A4 and M7A4 vehicles), Armored Multi-Purpose Vehicle (AMPV) production scaling to support Ukraine, M88A2 recovery vehicle production, and self-propelled howitzer system vehicle assembly — recent sub awards dated July through December 2025 reflect ongoing production and early-order material commitments for increased vehicle rates.
