Broad incumbents

• Resco Products: Manufacturer and supplier of refractory products with installation services for steel, non-ferrous, and other heavy industries. Comparable in delivering refractory installation and maintenance scopes for steelmaking equipment like Grupo Maresa does for Ternium.
• Vesuvius (Vesuvius plc): Global provider of refractory products and services to the steel and foundry industries. Comparable due to offering installation and maintenance of refractory linings for steelmaking equipment (ladles, tundishes, furnaces), directly overlapping Grupo Maresa's core fumistería scope but at global scale with refractory manufacturing as its base.
• Calderys (Imerys Group): International refractory solutions provider serving iron, steel, cement, and non-ferrous industries with installation services. Directly comparable to Grupo Maresa in blast furnace and steel ladle refractory installation services, but with global reach and own refractory production.
• RHI Magnesita: Global refractory manufacturer and installer with integrated services for steel and heavy industry. Comparable because, like Grupo Maresa, it performs refractory installation and maintenance on blast furnaces, BOF converters, ladles, and kilns worldwide — but at vastly larger scale and as part of a broader refractory manufacturing portfolio.
• Promat (Etex Group): Manufacturer of high-temperature insulation and fire protection products with industrial application services. Comparable due to overlap with Grupo Maresa's thermal/acoustic insulation work and high-temperature industrial installations, though Promat primarily manufactures materials rather than performing on-site refractory fumistería.
• HarbisonWalker International: North America's largest producer of refractory products and services with installation capabilities for steel, aluminum, and glass industries. Comparable as it offers both refractory materials and installation/maintenance services for industrial furnaces and vessels, similar to Grupo Maresa's end-to-end refractory work.
• Pyrotek: Global provider of thermal management solutions and engineered materials for aluminum, steel, and foundry industries. Comparable because it supplies consumable refractory and insulation products alongside technical services for high-temperature industrial equipment.
• Saint-Gobain (Performance Ceramics & Refractories): Major industrial group with refractory and high-performance ceramic product lines serving steel, glass, and cement. Comparable in the refractory installation/materials space, plus thermal insulation overlap through Isover and similar brands relevant to Grupo Maresa's insulation work.

Regional players

• Montisol Argentina: Argentine industrial thermal insulation contractor referenced in Grupo Maresa's project history (e.g., 1975 DODECILBENCENO project at La Plata). Directly comparable as a regional Argentine insulation services company with overlapping industrial verticals (metallurgical, petrochemical, oil and gas).

Direct peers

• SADE (Argentine industrial contractor): Argentine industrial construction and maintenance contractor active in pipelines and industrial plant works (referenced in Grupo Maresa's historical project list). Comparable as a domestic Argentine contractor competing for similar industrial maintenance, insulation, and construction scopes in the same client base.
