About Helwig Carbon Products Inc.
Helwig Carbon Products Inc., a self-certified small disadvantaged business and Subchapter S corporation based in Milwaukee, Wisconsin, manufactures carbon brushes, brush holders, and related electrical components for federal agencies as a prime contractor exclusively — 67 awards across 14 customer agencies, all in the prime role with zero subcontract activity. The company competes predominantly under Total Small Business set-asides, though recent defense work with Naval Sea Systems Command and Army Corps of Engineers carries no set-aside designation.
Helwig's capability portfolio centers on electrical contact brushes and brush holders (42 of 67 awards fall under PSC Electrical Contact Brushes and Electrodes), with secondary manufacturing in springs, transformer components, and power distribution equipment. Representative recent work includes a $29,285 firm fixed-price purchase order from the Bureau of Reclamation (awarded February 2026) for carbon brushes and holders to support Grand Coulee hydroelectric facility operations, a $19,948 warehouse stock replenishment order from the Bureau of Reclamation (August 2024), and an $18,461 purchase order from Naval Sea Systems Command for brush holders (March 2024). Earlier work included a $44,184 carbon brush contract with the Army Corps of Engineers (September 2021).
The Bureau of Reclamation anchors Helwig's customer base, accounting for 12 awards (combined potential value $138 thousand) and 40% of recent award volume. The Army Corps of Engineers ranks second across multiple component commands: the Corps itself (5 awards, $44 thousand), Engineering District Little Rock (2 awards, $98 thousand), and Engineering District Walla Walla (2 awards, $32 thousand). Naval Sea Systems Command holds 3 awards ($29 thousand). These five customer entities account for 61% of the combined potential value across the vendor's footprint.
Activity is sporadic and low-volume — one award in 2024, one in 2026, following a two-year gap. Combined potential value across all 67 awards totals $557 thousand, with obligated dollars at $651 thousand (117% of potential), indicating accelerated invoicing relative to contract ceilings. The company maintains no parent IDIQ, GWAC, or BPA position; all work flows through individual purchase orders. Average contract value ranges from $18 thousand to $44 thousand, reflecting the specialized component-supply nature of the business. Helwig has maintained SAM registration since 2001 and holds a consistent track record supplying precision electrical components to both civilian hydroelectric and defense electrical-systems operators.
