Based in Belgium, Viohalco S.A. is a diversified industrial holding company that orchestrates a broad portfolio of metal processing entities across Europe. With roots dating back nearly a century and a significant historical footprint in Greece, the company has evolved into a major force in the global heavy industry sector. Listed on Euronext Brussels and the Athens Stock Exchange, Viohalco manages distinct production segments—primarily aluminium, copper, cables, steel, and steel pipes—that collectively provide critical infrastructure for the modern maritime and offshore economies.
In the marine and offshore energy sectors, Viohalco acts as a central enabler of the blue economy through its specialized subsidiaries. The company’s cable manufacturing division is particularly prominent in the offshore wind industry, producing high-voltage subsea cables essential for connecting wind farms to onshore grids and linking island power networks. These operations are supported by vertically integrated facilities that feature private port capabilities, allowing for the direct loading of massive cable lengths onto cable-laying vessels, a logistical advantage that streamlines complex offshore installation projects.
Complementing its electrical infrastructure capabilities, Viohalco’s steel pipe segment supplies energy transport solutions for deep-water environments. These pipes are engineered to withstand high pressure and harsh subsea conditions, serving the oil and gas industry as well as emerging markets for hydrogen transport and carbon capture pipelines. Beyond energy infrastructure, the company is a vital supplier of materials for naval architecture and shipbuilding. Its aluminium division manufactures high-strength, corrosion-resistant alloys specifically designed for vessel hulls, superstructures, and high-speed catamarans, while its steel operations provide heavy plates for commercial shipbuilding and port construction.
Viohalco places a strong emphasis on research and development to meet the rigorous certification standards required by maritime classification societies. By continuously refining metallurgy and production techniques, the company ensures its materials can endure the corrosive and high-stress nature of marine environments. Through this comprehensive industrial network, Viohalco S.A. functions as a strategic partner to the global shipping and offshore sectors, driving the transition toward more resilient and sustainable marine infrastructure.
