Klostermann

What Klostermann does

Klostermann Group, headquartered in Gelsenkirchen, Germany and founded in 1911, is a manufacturer and full-service provider of illuminated advertising, wayfinding, and steel construction systems. The group operates through three legal entities: Klostermann GmbH (manufacturing), Klostermann Service GmbH (maintenance, logistics, civil engineering, and project management), and Klostermann Nederland B.V. (Benelux operations). The product portfolio covers illuminated advertising systems (Leuchtwerbung), advertising pylons, steel and metal substructures, wayfinding systems for train stations and airports, digital signage, and — more recently — installation and maintenance services for electric vehicle charging stations across Europe. Manufacturing is conducted entirely in-house and spans CNC-controlled metalworking (sawing, welding, edging, milling, laser cutting, bending, punching), vinyl plotting and lamination, vacuum-forming of plastics, painting, and electrical installation.

The commercial model is project-based and enterprise-oriented. Klostermann sells through dedicated industry-vertical contacts covering Automotive, E-Mobility, Gastronomy & Entertainment, Banks & Insurance, Wholesale & Retail, Mineral Oil, Wayfinding Systems, and Steel Constructions, executing turnkey contracts that span survey, visualization, permitting, manufacturing, assembly, and after-sales maintenance. A digital project management platform with tablet-based survey apps and a customer login portal supports multi-site brand conversion programs; the company states a capacity to retrofit 50+ locations per week, which is central to its mineral oil and retail rollouts. Pricing is quote-based and not publicly disclosed; revenue derives from one-time project contracts (signage, steel constructions, wayfinding, digital signage) plus recurring service and EV charging installation work.

Customer evidence spans blue-chip German and European enterprises — Mercedes-Benz, Volkswagen, Commerzbank, Allianz, IKEA, Shell, Aral, Burger King, Deutsche Bahn, Flughafen Düsseldorf — and concentration is diversified across at least seven verticals, though mineral oil and banking engagements show the deepest multi-site cadence. The group is privately held and family-controlled (Managing Directors Ludger Klostermann and Wilhelm Nierhoff), has grown to over 200 employees, and maintains ISO 9001, ISO 14001, SCC, and EcoVadis certifications together with E.ON Climate Protection Certificates (2022, 2025, 2026-2027) for use of 100% renewable electricity.
