Dema Costruzioni S.r.l.

What Dema Costruzioni S.r.l. does

Dema Costruzioni S.r.l. is an Italian metal carpentry and custom steel fabrication company headquartered in Caiolo, Sondrio, and operating since 2008 under Italian S.r.l. status with a workforce of approximately 14 employees (average age 32). The firm operates across industrial, civil, and mechanical construction, offering high-definition plasma cutting services, formworks and launching gantries, custom gates, infrastructure and interior carpentry, LED-integrated fire-proof railings, hydraulic systems, parking garage structures, and turnkey steelwork packages. It holds EN 1090 EXC3, ISO 9001:2015, ISO 3834-2:2006, OMECO welding licenses, EC marking, and NDT certification, and owns a patent on an LED railing release system used in its proprietary railing product.

The company's operating model is project-based custom fabrication rather than serial production. Revenue is generated through contracted steelwork for construction projects, supplemented by third-party manufacturing services introduced after the 2016 installation of the high-definition plasma cutting system. Customers are described as leading national construction companies active in Italy and Switzerland, with reference projects including the Isozaki Tower and a 2011 hydrogen plant in Bolzano indicating capability in regulated industrial and high-rise construction. Partnerships with CPTechnology, Della Cagnoletta, and Nieder extend the commercial reach.

Capital structure is private and self-funded, with no disclosed outside funding. The firm relies on certified personnel (WPS-licensed welders) and disciplined procurement to deliver complex, low-tolerance structural components. Geographic footprint is concentrated in northern Italy with cross-border activity in Switzerland; vertical exposure spans industrial infrastructure, civil buildings, and interior/architectural metalwork.
