Thy Marcinelle

What Thy Marcinelle does

Thy-Marcinelle S.A. is a Belgian metal manufacturer established in 1989 in Charleroi as the Belgian operating entity of Italy's Riva Group (Riva Forni Elettrici S.p.A.). The company produces three core steel products, smooth wire rod (fil machine lisse), reinforcing bars (rond à béton), and welded steel mesh (treillis soudés), using electric arc furnace (EAF) steelmaking. EAF technology is the company's central technical feature: it processes scrap steel feedstock into new product, with a lower energy and greenhouse gas footprint than integrated blast furnace routes, an advantage amplified by Belgium's relatively low-carbon electricity mix. Annual output is 700,000 tonnes, and the company states a 32% share of the Belgian steel market in the electric production segment, with a workforce of approximately 500 across its Charleroi headquarters and the Fontaine-l'Évêque production unit (Tréfileries de Fontaine l'Évêque).

The business is a pure B2B industrial operation. Products are sold directly through a sales-led commercial department to construction and infrastructure customers across at least five European national markets (Belgium, France, UK, Germany, Netherlands) enabled by product certifications CARES, AFCAB, OCAB, TÜM, and KOMO. Pricing is quote-based and not publicly disclosed. The company holds ISO 9001 quality certification since 2003 and ISO 45001 occupational health and safety certification since 2022, audited by Galio & Partners and CARES.

Revenue is not publicly disclosed. The company is a privately held subsidiary of the Riva Group, an Italian steel conglomerate with operations in Italy, France, Germany, Spain, Canada, and Belgium. Forward-looking investment is anchored by the Master Plan 2030 for the Charleroi site, covering new office construction, landscaped parking, green zones, cladding renovation, and photovoltaic installation, signaling long-term operational commitment and on-site decarbonization. The 2023 expansion of the scrap steel supplier panel points to active feedstock strategy to support EAF throughput.
