What SIA does

SIA (Società di Ingegneria Applicata, operating as Sia srl) is an Italian applied engineering company founded in the early 1980s by three engineers, headquartered in Torre del Greco with its operational base at a 2,000+ m2 facility in Acerra since 2019. The firm designs, builds, installs, and commissions custom industrial equipment across five interconnected business units: Scali di montaggio (assembly lines for aerospace, with 20+ years of experience), Lavorazioni meccaniche & Additive Manufacturing (3- and 5-axis CNC machining plus ten 3D printers for prototyping and small series), Banchi Prova (automatic and manual functional test benches, Industry 4.0 Ready, 40+ years of expertise), GSE / Ground Support Equipment (30+ years of know-how for aerospace and military, including certified overhaul up to 10T), and Automazione (in-house PLC, HMI, and SCADA software development). Underlying technical differentiation rests on multi-disciplinary engineering integration (mechanical, electrical, hydraulic, pneumatic, software) under a single roof, supported by a temperature- and humidity-controlled metrology lab with Hexagon CMM, Leica laser trackers, and Hexagon measuring arm.

The company serves enterprise clients primarily in the Aerospace and Defense and Railway verticals, with a smaller industrial manufacturing tail. Publicly named customers include Leonardo, Hitachi, Alstom, AnsaldoBreda, AnsaldoSTS, MBDA, AugustaWestland, Atitech, Ferretti Group, Masoneilan, MA Group, Fedeunina, Osimav, Marina Militare, Aeronautica Militare, and Ferrovie. The firm holds ISO 9001, ISO 9100 (aerospace), and NATO Cage Code certifications, and participates in civil and military aviation programs including ATR, Boeing 787/777/767, Bombardier, A220, A321, and M345/M346.

Revenue mechanics are project-based, quote-driven, and built around custom engineering solutions with no publicly disclosed pricing. The GTM motion is direct enterprise sales supported by long-standing client relationships, an Italian website with contact forms, and memberships in Unione Industriali di Napoli and the American Chamber of Commerce in Italy. Approximately 65% of projects are international, indicating an export-heavy footprint. The firm is privately held by its founders with no disclosed outside investment.
