Weldmac Manufacturing Company

Weldmac Manufacturing Company, a self-certified small disadvantaged business manufacturer based in El Cajon, California, delivers precision structural support components, turbine nozzle maintenance services, nonmetallic seals, and mounting brackets to the Defense Logistics Agency as a prime contractor (92% of recent awards) and subcontractor on Army helicopter modification programs. Weldmac is a limited liability company and child entity of RSA Engineered Products, LLC, competing predominantly on full-and-open basis—none of its recent prime awards carry small business set-aside designations, though earlier contracts note occasional small business set-aside history.

Weldmac's customer footprint concentrates almost entirely with DLA. The Defense Logistics Agency Aviation accounts for 137 awards and $26.3 million in combined potential value (93% of the total portfolio); DLA Land and Maritime adds 36 awards worth $1.7 million; and DLA Troop Support Hardware contributes 16 awards valued at $162 thousand. Together, these three DLA components represent 98% of award count and 100% of combined potential value. Secondary customer agencies—the Department of the Army and its subordinate commands—appear in only two prime awards and receive no dollar concentration signal.

Weldmac's capability footprint centers on aircraft and defense component manufacturing. Representative prime work includes a $921,453.75 definitive contract from DLA Aviation for turbine nozzle support services (awarded October 20, 2025, ultimate completion October 19, 2026), a $744,477.91 delivery order for structural support products (May 28, 2025), and a $491,280 delivery order for turbine nozzle support products (February 7, 2024). The company holds multiple single-award indefinite delivery contracts with DLA, including a $2,499,999.99 ceiling IDC for structural support components (awarded April 14, 2026, through April 13, 2028), a $2,000,000 ceiling IDC for structural supports and turbine nozzle services (May 26, 2023), and a $1,999,999.99 ceiling IDC for turbine nozzle support (July 30, 2021). These IDCs enable DLA to place firm-fixed-price delivery orders on demand. Work is performed at Weldmac's El Cajon facility and is characterized by specific national stock numbers—structural support plates, nonmetallic seals, mounting brackets, and turbine engine components serving military aviation, space, and defense platforms.

Activity has remained steady: 15 awards in 2022, climbing to 25 in both 2023 and 2024, declining to 19 in 2025, with 4 awards year-to-date in 2026. Two awards with ultimate completion dates in the next twenty-four months carry $1.1 million in combined potential value and present recompete exposure. The vendor's NAICS footprint is dominated by Other Aircraft Parts and Auxiliary Equipment Manufacturing (132 awards) and Gasket, Packing, and Sealing Device Manufacturing (43 awards), with smaller presence in Aircraft Engine and Engine Parts Manufacturing (19 awards).

Weldmac subcontracts to two major primes on Army helicopter modification work. As a subcontractor to Defense Systems and Solutions, Weldmac provides materials, manufacturing, and integration support for Aircraft Survivability Product Improvement kits, Common Missile Warning System kits, and Apache helicopter support across Foreign Military Sales programs for Poland and Greece, and UH-60M aircraft modifications for Jordan—recent sub awards include February 13, 2026 ($ASPI kits for Poland) and December 20, 2025 (UH-60M modification kits for Greece). As a subcontractor to The Boeing Company, Weldmac supplies aerospace support services on Apache AH-64E induction schedules and F-15EX production—recent examples include August 13, 2024 (Apache AH-64E schedule change) and March 27, 2024 (F-15EX Lot 4). The subcontract footprint represents roughly 8% of award count (17 sub awards) and constitutes a secondary revenue stream distinct from the DLA prime aircraft components focus.

Weldmac's parent, RSA Engineered Products, LLC, is also a for-profit manufacturer of goods based in Simi Valley, California, and holds multiple prime federal contracts independent of the Weldmac entity.
