Naturstein Steinmann GmbH

What Naturstein Steinmann GmbH does

Naturstein Steinmann GmbH is a German family-owned natural stone construction specialist founded in 1997 by master stonemason René Steinmann in Trossenfurt/Tretzendorf, now headquartered in Eltmann, Bavaria. The company delivers full-service natural stone projects spanning ventilated facades, floors, stairs, kitchen countertops, washbasins, garden and landscape elements, grave memorials, and heritage restoration. Its core technical differentiator is the proprietary Litho-Stone® modular lightweight natural stone system, which supports impact- and bomb-resistant facade applications, complemented by the LITHODECOR production facility (acquired from DAW Konzern in 2021) for stone/glass/ceramic composite facades and a sustainability sub-brand, Coolstones by Steinmann, which produces design objects from residual and salvaged stone.

The company serves architects, construction firms, and commercial real estate developers across Germany, with documented projects on DGNB Platin and LEED Platin certified buildings such as Ludwigshafen Rheingalerie (9,000 m²), Köln Holzmarkt 1 (5,870 m²), TaunusTurm Frankfurt, and Marienforum Frankfurt. Customers are engaged through a direct sales motion supported by five regional branch offices (Köln/Koblenz, Stuttgart, Dresden, Berlin, Hamburg) and own installation teams, with services structured into consulting and sales, technical planning, calculation, production, and on-site construction execution. Pricing is quote-driven per project, and revenue is project-based professional services plus hardware supply of modular facade components.

The firm remains owner-managed by the Steinmann family, with second-generation leadership (Jessica Steinmann joined management in 2019; Kevin Steinmann leads business economics and Coolstones). It reports 13 employees, six German locations including the Netzschkau production plant, no external institutional investors or funding rounds, and no public revenue disclosure. Recent strategic emphasis has been on sustainability credentials, certified green-building project delivery, and lightweight composite facade technology, positioning the company at the intersection of traditional stonemasonry and modern energy-efficient construction.
