What Steam does

S.T.E.A.M. S.r.l. (Società Termo Elettrico Aero Meccanica) is an Italian manufacturer and distributor of air-duct and HVAC components, founded in 1968 in Pomezia (Rome) and operated under Morgantini-family ownership across two generations. The company fabricates metal ductwork in galvanized steel, stainless steel, and copper across circular, rectangular, oval, micro-perforated, and pre-insulated panel formats, supplemented by in-house production of fire dampers, silencers, fan casings, and activated-carbon filtration units; its own sub-brands include Linea Clima, Linea Soft (EPDM-gasketed, leakage class C), and Linea Isol (mineral-wool insulated). Production capacity at the Pomezia facility is 120,000 kg of sheet-metal duct per month, supported by an on-site leak-testing laboratory that issues certified UNI EN 12237:2004 leakage-class documentation and offers on-site system testing.

The business operates a hybrid revenue model spanning three streams: (i) hardware sales of manufactured ductwork and accessory components through two physical retail/wholesale locations in Pomezia and Guidonia Montecelio and an e-commerce storefront; (ii) project-based engineering, installation, and mechanical-system contracting for civil, industrial, hospital, oil & gas, and fire-protection applications; and (iii) exclusive distribution and resale of partner brands including Lindab, Aernova, Multiclima, and P3ductal for the Lazio region, plus Daikin, Mitsubishi Electric, Toshiba, LG, Sinclair, ATAG, and K-FLEX HVAC equipment. Go-to-market combines enterprise field sales with technical consulting and on-site surveys for HVAC installers, contractors, and construction-company clients, supplemented by a quote-based, project-billed professional services arm. Headcount is 73 (52 production + 21 office), 2023 revenue was €34.4M (up from €11.4M in 2013), and the company holds ISO 9001/14001/50001, OHSAS 18001, F-Gas, SOA, and D.M. 37/08 certifications, qualifying it for regulated public works and specialized vertical tenders. In 2024 the commercialization leg was carved out into a separate entity, STEAM.COM, housed in a new 8,000 sqm warehouse.
