Wilhelm Modersohn

What Wilhelm Modersohn does

Wilhelm Modersohn GmbH & Co. KG is a German B2B manufacturer specializing in stainless steel (Edelstahl Rostfrei) fastening systems and industrial stainless steel components, founded in 1970 in Spenge, Germany, and operating as a subsidiary of the global construction fixing systems group Leviat. The company runs two divisions: a Construction division (Bauwesen) anchored on the proprietary MOSO® product brand — covering panel hangers, restraint anchors, bracket anchor systems (e.g., MK6), anchor channels, perforated strip masonry reinforcement, and the MOSOTHERM pressure-transmitting thermal separation system for facade applications — and an Industry division offering custom stainless steel profile manufacturing, water jet/laser/shear cutting, welding, assembly production, and surface treatment services including grinding, blasting, pickling, and electropolishing.

The underlying technology base combines decades of stainless steel metallurgy expertise with proprietary software (MOSOCONstructor for structural calculation and dimensioning of facade fastenings) and a vertically integrated manufacturing footprint spanning profile production through finishing. Modersohn was the first company to introduce Lean-Duplex steel (SAF2304 / 1.4362) for system products in the German fastening market in 2003, following a technology introduction from Avesta (Sweden) in 2002. The company holds multiple certifications relevant to structural and welding work — DIN EN 1090 EXC3, DEKRA specialist status, BAM federal materials testing approval — and is a member of the Warenzeichenverband Edelstahl Rostfrei e.V.

The business model is exclusively direct B2B project-based sales with quotation-driven pricing; no resellers or distributors are used. Customers — primarily facade construction firms, precast concrete manufacturers, and industrial buyers — engage through online project inquiry forms with file upload, phone, and email, and receive embedded in-house engineering consultation. The company serves both German and international projects, with marquee references including Elbphilharmonie Hamburg, V&A Museum Dundee, Moscow Metro, and the Edeka Hiltrup retail project. Delivery terms follow Incoterms 2020 (DDP or ex works). Pricing is not publicly disclosed.
