The Marangoni industry is consolidated, with the expansion of its product portfolio for the Brazilian market.

In 1956, Edmund Meiser founded the company in Limbach, Saarland, focusing on reinforcing steel for concrete. He learned early lessons in risk management after a severe currency fluctuation, setting the tone for disciplined growth.

Marangoni establishes itself as a trusted supplier and manufacturing benchmark in Brazil and across South America.

By 1960, Meiser entered the grating market. With just ten employees, he built his first hot-dip galvanizing plant in 1969, designed by his nephew Wilfried Geib, whose innovation solved a critical zinc-melting issue and shaped the company’s engineering culture.

Marangoni expands its operations by producing cooling systems for power transformers—radiators, cooling fans, and butterfly valves During this period, Brown Boveri acquires a 30% stake in the company.

The company built the BEA Hall, in 1972, for steel processing and, in 1976, added a new galvanizing line for serial products. These steps created the foundation for Meiser’s future large-scale production.

The new metalworking division is inaugurated, laying the foundation for the company’s current production plants. Around the same time, Marangoni becomes part of the ABB Group.

In 1980, Meiser launched Limbacher Verzinkerei GmbH and deepened vertical integration. Erich Petry became Sales Manager in 1983, and by 1990, the company had expanded into wire drawing, slitting, cold rolling, and stair manufacturing — securing strong self-sufficiency.

Invited by Siemens, Marangoni opened it’s first international branch Marangoni Andina, in Bogota, Colombia.

It later repurchased its shares from ABB, returning to full Brazilian ownership.

The 1990s marked rapid expansion: Fameco in Belgium, in 1991, Ferroste Kft. in Hungary, in 1992 through István Horváth, and Altenberg in Essen, in 1995. Wolfgang Meiser took over Sales & Marketing in 1996, while Frank Degenkolb and Dietmar Prätorius led Oelsnitz. Meiser became a European Grating Leader.

Marangoni implemented ISO 9001 and a corporate governance program. Following another invitation from Siemens, a new unit, Marangoni DOO., was established in Croatia. The galvanizing plant was launched in 2006, and the road safety plant in 2007.

Globalization accelerated. MULTI MEISER Egypt, in 2000, Ulrich Meiser joining Finance, in 2001, and Robert Vièl’s creation of LIONWELD MEISER - Dubai, in 2006, established the brand worldwide. Growth continued in Turkey, Sweden, Ostrava, and with a tubes division in Limbach.

Marangoni entered a joint venture with Meiser, a German company, establishing Marangoni•Meiser to specialize in metal grating. In partnership with Road Steel, part of Gonvarri Industries (Spanish company), the company expanded its production and supply of road safety systems. ISO 14001 was implemented as part of its commitment to environmental management.

Created a cutting-edge galvanizing and logistics hub in Limbach in 2011. MEISER do Brasil was founded in 2013, Marangoni-Meiser (Brazil) began operations with a fully automated, production line, providing a complete local supply chain. Oelsnitz was expanded with a modern galvanizing plant, and MEISER gratings Inc. was founded in the USA in 2019.

The “Skunk Works” department was created as a core innovation hub dedicated to the development and promotion of new Technologies. Marangoni formed a partnership with a Ukrainian startup to manufacture and sell the Mosqitter Brazil — an eco-friendly pest control solution.

A decade of leadership and acquisitions: VR (Easy-Rail/BBV), SORST Streckmetall. SEMITECH, Cugnart/Le Piquet EMCO (UK), and Meiser Produits de Sécurité (Nogent-sur-Oise). Acquiring IKG made Meiser the global market leader in gratings with factories in Houston (TX), Garrett (IN), and Querétaro (Mexico), in 2024.

Saarlouis galvanizing plant began operations, featuring powder-coating technology and operated by Coatinc Siegen GmbH, in 2025.
