Lamparter GmbH & Co. KG

What Lamparter GmbH & Co. KG does

Lamparter GmbH & Co. KG is a German specialist contractor in steel and glass construction, founded in 1947 and headquartered in Kassel with production facilities in Kaufungen. The firm operates as part of the Thelen Gruppe and employs approximately 25 staff, including roughly 10% apprentices, with two-thirds of its skilled workers trained in-house. The company focuses on the design, prefabrication, and installation of filigree steel-and-glass structures, with particular depth in pedestrian and connection bridges, facades (curtain wall, soundproof, insulated), glass roof systems (standard, flat, membrane), and special steel structures including contract manufacturing and renovation work. Its technical edge is concentrated in a direct-glazing-on-steel technique and a prefabrication approach that enables visually lightweight structures at architectural scale.

Lamparter generates revenue through project-based contracts with public and private-sector clients across Germany. The customer base includes corporate enterprises such as PUMA SE (85m glass bridge at Herzogenaurach, 2017), transit operators such as Hamburger Hochbahn AG (Skywalk, Hamburg, 2019) and HHLA, healthcare facilities such as Städtische Kliniken Karlsruhe and Klinikum Mittelbaden, retail destinations such as the Dreiländergalerie Weil am Rhein (3,500 sqm glass facade), and entertainment venues such as Miniatur Wunderland Hamburg (2020 bridge, awarded the 2023 Deutscher Brückenbaupreis). Project delivery has expanded geographically across Hesse, Hamburg, Baden-Württemberg, Bavaria, and North Rhine-Westphalia, with a recent 2026 connection-bridge project in Hadamar.

The business model is anchored to individual engineering specifications rather than recurring subscriptions, licensing, or volume pricing. Revenue mechanics are tied to one-off design, fabrication, and installation contracts, typically delivered in consortium or specialist-subcontractor arrangements with general contractors, architects, and public clients. The Thelen Gruppe parent structure provides corporate backing, while the apprenticeship pipeline functions as the primary mechanism for capability replenishment in a craft trade with documented skilled-labor scarcity.

Products and services

• Verbindungsbrücken (Connection Bridges) Steel and glass pedestrian bridges and walkways connecting buildings or spanning roads and infrastructure, featuring fully glazed designs. Used by infrastructure operators, transit authorities, real estate developers, and corporate/industrial clients requiring minimal installation disruption.
• Vorgehängte Fassaden (Curtain Wall Facades) Architectural facades including pre-elemented systems, glass facades, and custom metal cladding solutions for commercial and industrial buildings. Used by shopping center developers, office building owners, and commercial property developers with complex facade and energy efficiency requirements.
• Schallschutzfassaden (Soundproof Facades) Acoustic barrier walls and noise-reducing facade systems for industrial and commercial applications, including noise barrier walls alongside infrastructure. Used by infrastructure operators and commercial property developers in noise-sensitive locations.
• Glasdächer (Glass Roofs) Glass roof constructions including standard glass roofs, flat glass roofs (less than 5 degrees slope), and membrane/foil roofs. Used by shopping centers, commercial buildings, and architectural projects requiring natural daylighting and distinctive roof designs.
• Stahlbauten (Steel Structures) Custom steel building constructions and structural steelwork for various architectural and infrastructure projects. Used by developers and industrial clients requiring tailored structural solutions.
• Sonderbauten (Special Constructions) Specialized custom constructions including transport and logistics structures and artistic installations such as documenta art projects. Used by clients with unique construction requirements that do not fit standard bridge, facade, or roof categories.
• Lohnfertigung & Anarbeitung (Contract Manufacturing) Subcontract steel fabrication and pre-assembly services for third-party construction projects. Used by other construction firms and developers requiring specialized fabrication capacity.
• Bauen im Bestand (Renovation Construction) Steel construction services for existing buildings and renovation projects. Used by property owners and developers needing structural steel modifications or additions within existing built environments.

Direct peers

• Mero TSK: Mero is a German specialist in space-frame and steel-glass construction systems for atria, roofs, and complex geometries; its prefabricated structural systems and bespoke project engineering mirror Lamparter's filigree steel-glass approach.
• Seele: Seele is a German specialist in structural glass facades, glass roofs, and complex steel-glass constructions, with a portfolio of award-winning all-glass pedestrian bridges and facades that directly overlaps Lamparter's filigree steel-glass bridge and architectural envelope work.
• Donges SteelTec: Donges SteelTec is a German structural steel specialist delivering bridges, industrial buildings, and complex steel constructions — a direct peer on the structural steel/bridge side of Lamparter's portfolio, though with less glass-architecture emphasis.
• Permasteelisa (incl. Josef Gartner): Permasteelisa, which absorbed Josef Gartner, is a leading European curtain-wall and architectural envelope contractor with strong overlap in complex glass facades and bespoke structural glazing projects comparable to Lamparter's facade and roof portfolio.
• Waagner-Biro: Waagner-Biro is an Austrian specialist in steel and glass facades, stage engineering, and complex steel-glass structures, with a comparable project-based delivery model and direct overlap in glazed bridges and large-span architectural envelopes.

Broad incumbents

• Max Bögl: Max Bögl is a large German construction group with capabilities spanning structural steel, bridges, towers, and modular construction; its steel/bridge capabilities overlap with Lamparter's but it operates at much broader scale across infrastructure, wind energy, and precast concrete.
• Schüco: Schüco is a major German facade and window systems manufacturer with a broad product portfolio spanning residential, commercial, and high-end architectural envelopes; it overlaps with Lamparter's glass-facade work but competes primarily as a systems supplier rather than bespoke fabricator.
• Ed. Züblin AG: Ed. Züblin AG is a leading German general contractor (Strabag group) with structural steel, bridge, and building envelope capabilities; its broader scope and larger scale position it as a broader incumbent that can compete for the same complex steel/glass commissions.
