LK Metallwaren

What LK Metallwaren does

LK Metallwaren GmbH is a privately held German industrial plant-engineering company founded in 1976 and headquartered in Schwabach, Bavaria, with an additional operations site in Weißandt-Gölzau (Saxony-Anhalt) and a sales presence in the Czech Republic. The company designs, fabricates, and services custom industrial systems across five interconnected product areas: hall heating and ventilation (warm air generators, hybrid heaters, air purifiers, solar air collectors, ceiling fans, air curtains), industrial sound insulation (machine enclosures, sound-insulation cabins, noise walls, and silencers), water and wastewater treatment (oil and grease separators compliant with EN 858-1, sludge traps, tangential separators, multi-layer and membrane filtration including reverse osmosis, WHG catchment basins, and mobile separators), process engineering (LKPT compact systems and custom heat exchangers), and sheet-metal fabrication (precision CNC bending at the Schwabach facility). The firm is DIN EN ISO 9001 certified and holds LGA Fachbetrieb certification under §62 AwSV, which is a regulatory requirement for installing and maintaining water-hazardous-substance systems in Germany.

The business operates a project-based, custom-engineering model: each system is sized and configured to the customer's process requirements, with revenue generated through one-time equipment sales, multi-year payment terms (one-third deposit, one-third at delivery readiness, balance within 30 days of delivery), and an attached recurring service and inspection business (notably Abscheiderservice and WHG-compliant maintenance). Go-to-market is direct enterprise field sales — consultative, engineering-driven engagement with industrial and commercial buyers — supported by a content-marketing "Ratgeber" advisory blog, an active multi-platform social presence (LinkedIn, YouTube, Facebook, Instagram, Xing, X), and participation in German trade shows including IFAT, IFH/Intherm, LogiMAT, and Florian. Target customers span industrial manufacturing, industrial machinery operators, industrial water/wastewater treatment, process industry, automotive workshops, and commercial food service.

The company employs 51-100 people, is led by CEO Jochen Haberkorn, with sales headed by Harald Wimmer and procurement by Gerhard Gleixner, and is registered as a GmbH in the Amtsgericht Nürnberg commercial register. Ownership is private and management-led, with no disclosed parent company, no private-equity or venture-capital investors, and no external funding rounds. The company celebrated its 50th anniversary in 2026, and operating languages include German, English, and Czech.

Core offering

LK Metallwaren designs, engineers, and manufactures custom industrial plant systems for industrial and commercial customers in five areas: hall heating (warm air generators, ventilation, air purification), sound insulation (machine enclosures, acoustic cabins, silencers), water and wastewater treatment (separators, filtration plants, WHG catchment basins), process engineering (LKPT compact systems, special heat exchangers), and precision sheet metal fabrication. The company delivers integrated, environmentally conscious turnkey equipment rather than individual components, supported by ongoing maintenance and inspection services.

Product overview

LK Metallwaren is an industrial plant engineering company offering an integrated portfolio of five interconnected business areas: (1) Hallenheizung — hall heating systems including the LK Lüftungsanlage Reku, LK Hallenlüftung RK-K, Warmlufterzeuger GCS, Hybrid-Warmlufterzeuger RBW, Luftreiniger LRA 100, Torluftschleier, Solarluftkollektor, and ceiling fans; (2) Schallschutz — acoustic insulation solutions comprising Maschineneinhausungen, Schallschutzkabinen, Schallschutzwände, Schalldämpfer für Lüftungsanlagen, and Kulissenschalldämpfer; (3) Wasseraufbereitung — water treatment and wastewater systems including Abscheider/Leichtflüssigkeitsabscheider (EN 858-1), Behälterbau, Schlammfänge, Tangentialabscheider, Filtrationsanlagen (multi-layer filtration through reverse osmosis), Fettabscheider, Abscheiderservice, WHG-Auffangwannen, and mobile separator units; (4) Prozesstechnik — process engineering solutions including the LKPT Kompaktanlage and Spezialwärmetauscher; and (5) Metallwaren — sheet metal fabrication and processing at the Schwabach facility. The company positions itself as a full-service provider combining engineering, manufacturing, and service for environmentally conscious industrial plant construction.

Broad incumbents

• Viessmann: Major German heating, industrial, and refrigeration systems manufacturer. Comparable in hall and industrial heating, but vastly larger scale and broader portfolio including heat pumps, boilers, and digital services — competing for the same industrial customer wallet.
• Vaillant Group: European heating, ventilation, and hot-water manufacturer. Competes indirectly in industrial and commercial heating segments and represents the kind of large incumbent LK Metallwaren must differentiate against through custom engineering.
• GEA Group: Global process engineering and heat-exchanger specialist. Comparable to LK Metallwaren's Prozesstechnik line, particularly Spezialwärmetauscher and LKPT compact systems, but operates at vastly larger scale across food, dairy, and chemical process industries.
• ACO Ahlmann SE & Co. KG: Large German water-management company producing separators, drainage, and wastewater treatment systems. Overlaps with LK Metallwaren's Wasseraufbereitung portfolio, particularly oil/light-liquid separators and WHG-compliant containment, but operates across a far broader product and geographic footprint.
• Wolf GmbH: German heating and ventilation systems brand (part of Bosch). Overlaps with LK Metallwaren's hall heating and air-handling products for commercial and light-industrial customers, with significantly greater scale and channel reach.
• Bosch Thermotechnology: Global heating and hot-water solutions provider (including the Buderus and Wolf brands). Competes with LK Metallwaren in industrial and commercial heating, with overlapping certifications and a much larger installed base.
• Stiebel Eltron: German heat-pump and heating technology manufacturer. Adjacent competitor in industrial and commercial heating, increasingly relevant as customers electrify — a strategic threat and potential benchmark for LK Metallwaren's energy-transition roadmap.

Direct peers

• Menerga GmbH: German specialist in energy-efficient heating and cooling for industrial and commercial buildings. Comparable to LK Metallwaren's hybrid warm-air heaters and ventilation systems, with overlapping target customers in industrial halls and process facilities.
• Fränkische Rohrwerke: German manufacturer of industrial ductwork, ventilation pipes, and drainage systems. Comparable to LK Metallwaren's sheet metal processing and ventilation/ducting components, serving overlapping German industrial and HVAC contractor customers.
• Kampmann GmbH: German manufacturer of industrial hall heating, air-conditioning, and ventilation systems. Directly comparable to LK Metallwaren's Hallenheizung portfolio, serving the same German industrial and commercial customer base with custom-engineered heating and air distribution solutions.
