Vesuvius

What Vesuvius does

Vesuvius plc is a London-headquartered engineered ceramics company that designs, manufactures and services molten metal flow engineering and high-performance refractory products primarily for the global steel and foundry industries. The company operates through two divisions: Steel (comprising Steel Flow Control — slide gate systems, isostatically pressed products and the XMAT 'expert eye' mould instrument; Advanced Refractories — monolithics, pre-cast shapes and bricks for blast furnaces, ladles and tundishes; and Technical/Digital Services) and Foundry (trading as Foseco, supplying consumables such as feeding systems, filters, crucibles and coatings to iron, aluminium and solar-crucible customers). Underpinning the portfolio is a century of process know-how, with 1,570 granted patents and 150+ patent families protecting technologies such as VISO isostatic pressing and ROTOLOK flow control, supported by 17 R&D centres globally and approximately £33.2 million of annual R&D spend.

Vesuvius monetises predominantly through one-time sales of customised engineered consumables and capital products, with pricing conducted on a quote basis via an enterprise field-sales model. Roughly 3,000 of its 11,000+ employees are embedded at customer sites to apply products and provide technical services, which deeply couples Vesuvius into customer operating workflows. The Steel Division accounts for the majority of group revenue (with Foundry/Foseco contributing ~30%) and the new Digital Services business is positioned to layer data-driven expert process management on top of the refractory product base, while R&D investment supports a 20.5% new product sales ratio and 24 new products launched in 2025. The company operates 55 production and sales sites on six continents, selling into more than 100 countries from a 38-country operating footprint, and runs a regional manufacturing model in which products are typically produced on the same continent as the customer.
