Metalogalva – Irmãos Silvas, S.A. is a Trofa manufacturer of steel structures — lattice transmission towers, lighting columns and poles — with its own hot-dip galvanising, founded in 1971 and the oldest company of the Vigent Group. In September 2024 Denmark’s transmission-system operator Energinet named it one of three winners of an eight-year framework agreement to supply lattice towers to Denmark.
Metalogalva was founded in 1971 in Trofa, north of Porto, and describes itself as the oldest company of the Vigent Group, which today counts more than 20 industrial units and a workforce of over 2,500 people. The Trofa company, with share capital of €5 million, is registered under CAE 25110 for the manufacture, galvanising, painting, assembly and repair of metal structures, including engineering design and testing; its product range runs from lighting columns and poles to the lattice towers that carry high-voltage lines.
Its Nordic customer is Denmark’s transmission-system operator. Energinet Eltransmission A/S awarded an eight-year framework agreement for the procurement, production and delivery of lattice towers to Denmark to three suppliers — Metalogalva, Mitaş Endüstri of Ankara and Carl C. A/S of Skjern — in a contract-award notice published on the EU’s Tenders Electronic Daily on 2 September 2024 (notice 524008-2024), with a framework value of €115 million.
Transmission-grid expansion is among the largest investment programmes in the Nordic energy system, and system operators such as Energinet buy much of the hardware through EU-advertised frameworks open to European suppliers. Metalogalva’s place on Energinet’s tower framework is a concrete example of a Portuguese heavy-fabrication firm competing for, and winning, Nordic transmission hardware against Turkish and Danish rivals — and of the procurement journal as the route in.
