What STF does

STF (Officina Meccanica S.T.F. s.r.l.) is a privately held Italian precision mechanical subcontractor founded in 1988 in Barzago, Lecco. The name derives from 'Società Tornitori Fresatori' (Turners and Millers Company), reflecting its core competencies in CNC turning (up to Ø1250 x 6000mm), milling (0-6000mm), and boring (0-4000mm). Operations run from a single 4,200+ sqm production facility with a 10-tonne lifting capacity, equipped with MCM, LAZZATI, and SORALUCE CNC machinery, radio probe dimensional control, and QR-code production traceability. The company produces custom parts to client drawings — from single pieces to complete order management — and bundles raw material sourcing, heat treatments, grinding and lapping, gear cutting, welding, dimensional controls, NDT, and logistics into its service offering.

STF serves eight industrial verticals: industrial mechanics and gearboxes, oil and gas, presses, recycling, steel, cement, sheet metal, and extrusion. Go-to-market is sales-led, with direct client relationships and dedicated technical consulting; pricing is quotation-based on technical specifications, materials, and required services, typically under multi-year contracts. The customer base is concentrated in Lombardy and Northern Italy, with European reach pursued via the Made in Lecco export portal.

The business reported €4,212,135 in revenue for FY2024 and employs approximately 20 people plus 3 partners/owners. Governance is founder/partner-controlled under Italian s.r.l. law, led by President and CEO Matteo Ratti, with 95% of the workforce on permanent contracts and 867 hours of training delivered in 2024. Quality, environmental, and safety credentials are central: UNI EN ISO 9001:2015 was achieved in 2024, UNI EN ISO 14001:2015 is held, and ISO 45001 (2026) and ISO 50001 (2027) are targeted — together with membership in Confapi Lecco e Sondrio, Rete Lariana per la Transizione Sostenibile, and the Made in Lecco territorial project.
