What Litostroj Group does

Litostroj LPTS (legal entity LPTS d.o.o.) is a Slovenian specialty foundry and machining company headquartered in Ljubljana that has operated continuously in iron and steel manufacturing since 1946. The company produces individual or low-series, complex-shaped medium-to-heavy castings weighing between 5 kg and 50,000 kg, made from steel and special alloys including austenitic and martensitic stainless grades, 9-12% Cr heat- and creep-resistant steels, and wear-resistant white cast iron. Core production is supported by in-house melting via a 3-5 ton electric arc furnace, heat treatment facilities capable of 7m x 7m x 4m at up to 1050°C, precision machining including a newly installed 5-axis CNC milling machine with 50 kW milling power, and a comprehensive quality lab offering NDT, ultrasonic, radiographic, magnetic particle, and dye penetrant inspection (ISO 9001 certified).

The company's product portfolio spans seven core casting lines — turbine components (hydro turbine regulation equipment, Kaplan and Francis runners), pump and valve components, industrial machinery parts, power generation components (steam and gas turbine casings, rotors), mining and mineral processing equipment, marine and shipbuilding parts, and steel/heavy industry equipment — complemented by seven in-house services from pattern making and alloy refining through to casting repair. Customers are industrial OEMs and operators in hydropower and renewable energy, thermal power, pumps and valves, mining, marine, and general heavy industry, served on a direct, project-based, quote-driven B2B basis with multi-year contracts typical for complex components.

Revenue is generated exclusively through custom, one-off manufacturing orders with no standardized pricing or public price list; all quotes are specification-driven. Go-to-market is enterprise field sales via the corporate website, LinkedIn presence, and direct contact, with the company self-positioning as a global market player for complex hydro and thermal turbine parts. Leadership is led by CEO Miroslav Gnamus. No parent company, external investors, M&A activity, or public funding rounds are disclosed in the source data.

Broad incumbents

• Voestalpine AG: Austrian steel and metal-component group operating foundries and specialty steel divisions serving energy, automotive, and industrial markets. Larger incumbent with overlapping capabilities in heavy steel castings and special alloys, competing for similar industrial casting customers.
• Voith Hydro: Major German hydro turbine OEM with in-house casting and machining capabilities for large turbine runners and components. Competes for hydro turbine work and is also a potential customer for independent foundries like Litostroj.

Emerging players

• ANDRITZ Hydro: Global hydro turbine OEM and service provider that both competes for and sources from independent foundries like Litostroj. Comparable because it operates in the same hydropower value chain, with foundry-adjacent capabilities in casting, machining, and refurbishment.
• Trench Group: German manufacturer of specialized cast coil transformers, coils, and sensor components serving power generation and transmission customers. Partial overlap as a specialty industrial casting/machining supplier serving power utilities.

Direct peers

• Metaltek International: US-based custom metal castings manufacturer producing heavy steel, alloy, and corrosion-resistant castings for pumps, valves, mining, and power generation. Direct peer in custom heavy casting market with similar product mix and customer segments.
• Pacific Steel Casting Company: US custom steel foundry producing heavy castings up to 50,000 lbs for industrial machinery, mining, and power generation. Closely comparable scale and product range to Litostroj's 5kg-50,000kg custom casting envelope.
• Doncasters Group: UK-based independent precision castings manufacturer supplying complex steel and alloy components to aerospace, industrial gas turbines, and industrial markets. Directly comparable as a custom foundry serving heavy industrial customers similar to Litostroj's hydropower/thermal/mining verticals.
• Bohler Edelstahl (voestalpine High Performance Metals): Austrian specialty steel producer with foundry operations producing high-grade steel and alloy castings for power generation, mining, and industrial machinery. Comparable in metallurgical expertise and target verticals.
• Hayward Tyler: UK/US specialist in cast and machined components for turbomachinery, pumps, and power generation. Highly comparable given its focus on cast pump and turbine components for industrial and energy customers, with similar custom-project sales motion.

Others

• Norican Group (DISA / Wheelabrator): Global supplier of foundry equipment, casting lines, and surface treatment technologies. Adjacent/ecosystem peer — Litostroj is a potential customer for Norican's foundry equipment, and Norican's customer base overlaps with Litostroj's end markets.
