What INMET Stahl GmbH & Co. KG does

INMET Stahl GmbH & Co. KG is a family-owned German steel service center founded in 1970 by Hartmut Kamp in Hagen and now headquartered in Bochum, Nordrhein-Westfalen. The company purchases wide steel coils and processes them into slit strip (Spaltband), electrically welded structural tubes and hollow sections (Rohre), and cold-formed profiles (Profile), with an additional stamping, bending, and deep-drawing line for finished components. Its wholly owned subsidiary bowa Stahlprofil, based in Plattling, operates a fully automated profiling line producing laser-welded steel sidewall profiles for commercial vehicles.

The processing platform is built around modern Voest-Alpine-designed pipe welding equipment capable of producing tubes up to 180x180x12.5mm, slit lines that handle coils up to 1,600mm width and 12mm thickness, and a company-owned railway siding that supports inbound coil logistics. The integrated facility spans 50,000 square meters of production area with annual slit band capacity of approximately 130,000 tons. Quality systems are anchored by ISO 9001:2015 certification, CE marking per DIN EN 10219-1:2006 for cold-formed structural hollow sections, and a 2023 "Energiebewusstes Unternehmen" energy-efficiency certification.

Commercially, INMET operates a direct, sales-led B2B model targeting German industrial customers in automotive, construction, mechanical engineering, and commercial-vehicle manufacturing. Revenue is generated through hardware sales of processed steel products on a quotation basis; pricing is not publicly disclosed. The company employs approximately 100 people across its Bochum and Plattling sites and maintains three Geschäftsführer (managing directors) drawn from the Kamp family and long-standing management. No external institutional investors, funding rounds, or international expansion are disclosed in the source material.

Core offering

INMET Stahl GmbH & Co. KG operates a steel service center that purchases steel coils and processes them into three core product lines: slit strip (Spaltband), welded construction tubes and hollow profiles (Rohre), and cold-finished profiles (Profile). The company manufactures to DIN/EN standards and customer specifications, supplying automotive, construction, mechanical engineering, and commercial vehicle customers in Germany with annual output of approximately 130,000 tons of slit band.

Product overview

INMET Stahl GmbH & Co. KG operates as a steel service center with a diversified product portfolio centered around three core product lines: Spaltband (slit strip steel), Rohre (tubes/hollowness profiles), and Profile (cold-finished profiles). The company also manufactures specialized Stanzbiege- und Tiefziehteile (stamping/bending and deep-drawn parts) primarily serving the automotive, construction, and mechanical engineering industries. A subsidiary branded 'bowa Stahlprofil' produces automated laser-welded steel sidewall profiles for commercial vehicles at its Plattling facility. The company operates a unique combination of slitting, tube, and profiling lines in Germany, enabling flexible response to market fluctuations.

Direct peers

• BENTELER Steel/Tube: Operates steel processing and tube manufacturing divisions serving automotive and industrial customers in Europe. Comparable product mix (welded steel tubes, profiles) and automotive customer overlap make it a direct competitor in INMET's core segments.
• voestalpine AG: Austrian steel and technology group with extensive steel processing, tube, and profile capabilities. Particularly relevant as voestalpine's equipment division (Voest-Alpine Industrieanlagenbau) designed INMET's pipe welding facilities, indicating overlapping technology and product scope.
• Wuppermann Stahl: German family-owned steel processor operating a network of service centers with slitting, cut-to-length, and tube-forming capabilities. Closely comparable in scale, ownership structure, product mix (flat steel, tubes, profiles), and German industrial customer base.

Broad incumbents

• Salzgitter AG: Major German steel producer and processor with steel service center operations under the Salzgitter Mannesmann and Peiner Träger brands. Competes with INMET in structural hollow sections and flat steel products but at much larger scale as an integrated steel group.
• Swiss Steel Group: European specialty and engineering steel producer with downstream processing. Overlaps with INMET in steel processing for automotive and industrial customers, though focused on higher-alloy specialty grades rather than commodity flat steel.
• Tata Steel Europe: European operations of Tata Steel include flat steel production and downstream service center activities in the Netherlands, UK, and elsewhere. Competes with INMET in flat steel products serving automotive and construction customers.
• SSAB: Nordic steel producer with strong presence in high-strength steel and service center offerings to automotive and construction customers. Competes with INMET in premium flat steel segments where INMET positions its products.
• ArcelorMittal Europe: World's largest steel producer with extensive European flat steel and downstream distribution operations. Competes with INMET in flat steel supply and processing, though at vastly larger scale and broader portfolio.
• thyssenkrupp Steel Europe: Germany's largest flat steel producer with downstream service center and processing activities. Competes with INMET in flat steel and downstream processed products but as a fully integrated mill rather than a service center specialist.
• Kloeckner Metals (formerly Klöckner & Co): One of Europe's largest steel and metal distribution groups with multiple service centers. Overlaps with INMET in slit strip and processed steel products but operates at substantially larger scale and broader geographic footprint.
