Manni Group People
Established in Verona in 1945 to trade ferrous materials and recovered metals, today Manni is an international steel industry player.
In that period of my childhood, one of my favourite toys was Meccano, which I spent many afternoons creating complex constructions with… However, I would have never imagined that this way of assembling prefabricated metal elements could be applied in the real world of construction.
This boy with a Meccano box and post-war Italy had one thing in common, an unrestrainable desire to build.
And so began Giuseppe Manni’s adventure alongside his father Luigi, the Group’s founder, then faced with the poverty of the post-war period and inspired by the idea trading ferrous waste and scrap. His firstborn Giuseppe gradually transformed this small business into a leading European industrial group, his added value being those very skills he had learned at home and in his father’s workshop, where life and work blended into one. A story of passion and hard work, dotted with milestones and successes destined to be remembered, not only by the company but by the community in general: a brilliant, representative heritage, epitomised by the steel Star, produced by Manni Group for its city , that every winter since 1984 “arises from within the age-old Arena of Verona and lands on Piazza Bra”.
Giuseppe Manni has been at the helm of the Group for 60 years now, and always with the same forward-looking inquisitiveness he had as a child 60 years ago, when his future was a blank page waiting to be filled.
For 80 years, a milestone we are celebrating this 2025, we have been offering the Italian and global markets an innovative building concept based on Modern Methods of Construction. Since the first generation, we have been pursuing this innovative approach to doing business with conviction: the construction world is undergoing a revolution, and every revolution starts with a cultural revolution first of all. Our mission is to contribute to this cultural revolution, which we do through activities that promote the application of off-site technologies on a daily basis. 2024 was a year that confirmed our values and shared vision. We embarked on paths that were completed fully in 2025, such as the joint venture with Marcegaglia Steel: a collaboration that marks a turning point in Manni Group’s internationalisation strategy, and strengthens our placement on a global scale. This synergy takes on an even more significant value because it combines with Isopan’s 50th anniversary, an anniversary that celebrates half a century of expertise, industrial evolution and ability to stay ahead of the challenges the sector poses. Looking to the future, we continue to invest in sustainable solutions, and actively contribute to decarbonising construction and consolidating our commitment to a future built on innovation, responsibility and positive impact.
2024 and early 2025 were periods of profound political change, with significant social and economic impact that was radical compared to past experiences. 2025 is also the year in which our Group, which has always focused on a long-term vision and business sustainability, celebrates its 80th anniversary. The effort to build long-lasting organisations has taken great skill in the various processes, and has forced us to react with flexibility, adaptation and innovation in the face of systemic crises. This is only possible by expressing a vision to steer the business into the future, one in which we can shape the chaos that surrounds us as much as possible. We believe that investments in R&D and in creating highly qualified partnerships now form the basis of our national and international development trajectories. We therefore maintain the process of internationalisation and technological innovation, with the necessary geographical adaptations and appropriate attention to supply chain adequacy by collaborating with leading global companies, research centres and universities. Giving the market products, systems and services that contribute to improving ESG impacts remains a central goal. In a trend of political hype that would seem to slow down or mute sustainability topics, we believe instead that these are a current that has become a widespread requirement, which is demanded and greatly needed. When looking ahead, we look further with the contribution of younger generations, who are crucial to the technological and sustainable development of (their) future.
The history of Manni Group began in 1945, when Luigi Manni founded the first steel trading business. In the 1960s, Manni Prodotti Siderurgici was established, marking the company’s industrial transformation under Giuseppe Manni. In 1972, the first Manni Sipre service center opened, and in 1980, it acquired Officine Riunite F.lli Lancini. Two years later, the Group’s headquarters, “Il Palazzetto”, was inaugurated.
In 1989, Isopan joined the Group, specializing in insulating panels, and in 1995, Gruppo Manni SpA was formally established. Strategic growth followed with the creation of the holding company Manni HP in 2000, Isopan Ibérica in 2001, and the Isopan SpA plant in Trevenzuolo in 2002.
International expansion continued with the launch of Isopan Est (2007) and the Inox Service Center (2008) with Manni Inox. In 2011, Manni Energy was founded, followed by the creation of IsoCindu in 2014, a joint venture for the Latin American market.
The Group kept growing with the launch of Manni Store in 2016 and Manni Green Tech in 2017. In 2020, Maetrics became part of Manni Energy. Recent years brought further consolidation: in 2022, Manni Sipre acquired Metallurgica Piemontese Lavorazioni Srl (TO), and in 2023, Manni Energy acquired Tecnogest Srl. In 2024, Manni Store became Isopan Store, and in 2025, Isopan entered into a joint venture with Marcegaglia Steel.
Today, 80 years after its founding, Manni Group continues to innovate and invest in the future, staying true to its core values of family, entrepreneurship, and international vision.
