About De Perini Metal Fabricators
De Perini Metal Fabricators operates a 25,600-square-foot plant in the Montgomery County Airpark at Gaithersburg, Maryland, with convenient access to Interstates 270, 495, 95 and 695. The woman-owned Maryland corporation was established in 1960 and is managed by a professional staff that oversees both prototyping and full-scale production. The facility houses sheet metal fabrication, machining, welding, assembly and finishing departments. Sheet metal work centers on an Amada 4-kW laser cutter and Strippit and Trumpf CNC punching systems, while machining relies on Haas VF-4 vertical machining centers capable of holding 0.005-inch tolerances. Certified welders perform TIG/MIG, spot, brazing and soldering to military specifications, and hardware insertion runs on Haeger equipment. Finishing includes Mil-Spec wet and powder coating, chemical conversion coating per MIL-DTL-5541 (Type 1 gold and RoHS-compliant Type 2 clear), and stainless-steel passivation to QQP35 and AMS 2700 standards. De Perini serves military, government and commercial customers, fabricating parts from aluminum, steel, copper, stainless steel, bar stock and plastics. The shop handles both short- and long-term projects with scheduled deliveries. The company emphasizes its ISO 9001:2015 quality system, continuous improvement and on-time delivery, with every employee responsible for quality verification before shipment.
