What RHI Magnesita does
RHI Magnesita is the world's largest supplier of refractory products, systems, and services, headquartered in Vienna and dual-listed in London and Vienna. The company was formed in 2017 through the merger of Austrian RHI and Brazilian Magnesita, with corporate roots extending back to 1834, and employs over 10,000 people across a vertically integrated footprint spanning magnesite and dolomite mining, refractory manufacturing, installation, and end-of-life recycling.
Its core products are high-temperature ceramic linings and pre-formed shapes used to contain molten metal, slag, and heat in steel, cement, glass, and non-ferrous metal furnaces. Active product platforms include EVER, ANKRAL LC, and RADEX AF-LC, marketed on durability, energy efficiency, and lower-CO2 performance. The company also delivers digital process monitoring through tools such as e-GEKKO and Agellis, and is investing in circular-economy and carbon-capture partnerships (MCi Carbon, Khemka Refractories JV) to support customer decarbonization.
RHI Magnesita generates revenue primarily through the sale of refractory products bundled with on-site installation, condition monitoring, and end-of-life recycling under multi-year supply agreements with industrial customers such as Tata Steel and other global steel and cement producers. The business model combines consumable product volumes with high-margin services and an emerging circular-economy revenue stream; FY2025 group revenue was €3.4B at an 11.1% EBITA margin. The 2025 acquisition of Resco Group for $410M added North American scale, while ongoing capacity investments in India target one of the world's fastest-growing steel markets.

RHI Magnesita competitors and assessment
Company assessmentDirect peers
- Vesuvius plc: London-listed global leader in refractory products and solutions for the steel, foundry, and glass industries. Closest direct competitor to RHI Magnesita with overlapping product lines (bricks, monolithics), customers (steelmakers), and end-market exposure.
- HarbisonWalker International: One of the largest North American refractory producers, serving steel, iron, glass, and cement customers. Directly comparable given RHI Magnesita's recent Resco-driven push into the U.S. market and similar product portfolio.
- Morgan Advanced Materials: U.K.-listed advanced materials company producing ceramic-based refractory and insulation solutions for steel and industrial applications. Active RHI Magnesita partner (March 2026 collaboration) and direct competitor in steelmaking thermal performance.
- Allied Mineral Products: U.S. privately held refractory manufacturer specializing in monolithic and pre-cast shapes for steel, iron, and aluminum. Directly comparable niche competitor, especially relevant given RHI Magnesita's expanded North American footprint post-Resco.
- Pyrotek: Privately held global supplier of high-temperature materials and refractory solutions for aluminum, glass, steel, and foundry industries. Comparable product breadth and end-market focus, particularly in nonferrous metals processing.
Broad incumbents
- Saint-Gobain: Global building materials and high-performance materials group with a refractory/adhesives footprint alongside much larger construction products business. Comparable for end-market exposure (cement, industrial) but far broader in scope than RHI Magnesita.
- Imerys: French specialty minerals group producing industrial minerals including refractory raw materials (magnesia, calcium aluminates via Kerneos). Comparable upstream in RHI Magnesita's magnesite supply chain and serves overlapping high-temperature industrial markets.
Regional players
- Shinagawa Refractories Co., Ltd. Japan's largest refractory manufacturer serving steel, cement, and glass customers across Asia. Comparable in product portfolio and end markets, but geographically concentrated in Japan and broader Asia rather than Europe/North America.
- Krosaki Harima Corporation: India-headquartered refractory producer (formerly Tata Refractories) serving steel, cement, and other heavy industries. Comparable product offering with strong Indian market presence — relevant given RHI Magnesita's India expansion and Khemka JV.
Others
- Resco Group (Resco Products, Inc.): U.S.-based refractory products manufacturer acquired by RHI Magnesita in January 2025 for $410M. Now a wholly-owned subsidiary rather than independent peer, but historically a direct competitor in North American cement, steel, and aluminum refractories.
