The Company
Döring Metalcostruzioni is a metal construction company founded in 1972, with its headquarters and workshop (over 500 m²) located in Losone in the Canton of Ticino. The company manufactures custom metal constructions for private customers, industry, and construction: general metal structures, metal construction and locksmith work (Carpenteria metallica), railings, gates and fences, metal stairs, metal facades, awnings and coverings, as well as chimneys and conservatories. Materials used include stainless steel, steel (Ferro), and aluminum. Services also include planning and design, utilizing AI-supported renderings; implementation takes place in the company's own workshop, and assembly is done at the customer's site.
