About the company
The Union Iron Works, doing business as Bemac Supply, a veteran-owned small business headquartered in McAlester, Oklahoma, supplies industrial piping components, fittings, valves, and infrastructure maintenance equipment to the federal government as a prime contractor across 82 awards totaling $3.2 million in combined potential value. The vendor operates almost exclusively under Total Small Business set-asides (approximately 40% of recent awards carry explicit small-business set-aside designation) and competes predominantly within small-business reserved procurement channels; the remaining awards are issued on a full-and-open basis through the same contracting officer.
Customer concentration is extreme and monolithic. The Department of the Army Materiel Command Joint Munitions Command accounts for 68 of 82 awards (83% of the portfolio by count) and $3.1 million of the $3.2 million combined potential value (97% of dollars). The remaining five agencies—the Department of the Army, Department of the Army Corps of Engineers Engineering District Tulsa, Department of the Army Corps of Engineers, and Department of the Interior National Park Service Intermountain Region—collectively represent nine awards with less than $104 thousand in combined potential value. This concentration reflects Bemac Supply's role as an established supplier to the McAlester Army Ammunition Plant, where it has maintained a registered SAM.gov account since 2001.
Bemac Supply operates under a $250,000 Blanket Purchase Agreement with the Joint Munitions Command (Agreement W44W9M21A0001), from which 29 task orders have been issued carrying $308 thousand in combined potential value. The vendor delivers piping materials—including PVC (Megalug, C-900 DR-14), hard copper, stainless steel, and pressure-rated components in multiple diameters—alongside plumbing fixtures, water system infrastructure, fire suppression equipment, and maintenance parts. Representative recent awards include a $374 thousand May 2025 purchase order for C-900 DR-14 PVC pipes for fire suppression system upgrades, a $322 thousand April 2025 order for 10,680 linear feet of pressure-rated PVC piping across three sizes, a $123 thousand July 2025 call for a purchase description list of industrial supplies, and a $50 thousand August 2026 purchase order issued by the Joint Munitions Command. Category concentration is aligned with this footprint: Plastics Pipe and Pipe Fitting Manufacturing (49 awards), Industrial Valve Manufacturing (4 awards), and allied categories account for 59 of 82 awards. PSC coding reflects the same emphasis—Pipe, Tube and Rigid Tubing (47 awards) and Miscellaneous Construction Materials (8 awards) dominate the profile.
Activity has been volatile and remains thin. The vendor received six awards in 2022, six in 2023, five in 2024, ten in 2025, and one award through August 2026, reflecting uneven annual procurement from a single customer agency. The recompete cliff is minimal: only one award with ultimate completion in the next twenty-four months carries $51 thousand in potential value. Bemac Supply operates as a 100% prime contractor with no recorded subcontract relationships, concentrating its business on direct supply to the Joint Munitions Command's infrastructure and equipment needs at a single facility location in Oklahoma, with performance also taking place at Tooele, Utah and San Ramon, California for specific equipment installations.
