What BSB & BWB does

BSB & BWB is the operating trade name for two legally independent German industrial metalworking companies headquartered at a single 35,000 m² site in Burgau, Bavaria: BSB Metallverformung GmbH + Co. Stanzwerk (founded 1969, ~220 employees, ~€26 million turnover) specializes in high-tonnage stamping and forming of sheet metal (0.8-16 mm thickness, up to 1,000 t press force), welding and laser cutting of steel/stainless/aluminum, in-house tool and fixture construction, and a broad range of surface coating services (powder coating, wet painting, galvanizing, KTL, sherardizing). BWB Behälter-Werk Burgau GmbH + Co. KG (founded 1994, ~90 employees, ~€20 million turnover) designs and manufactures compressed air tanks up to 800 litres and oil separators in steel, stainless steel, and aluminum, holding multi-jurisdictional pressure vessel approvals.

The two entities operate as a coordinated B2B manufacturing platform under the Klimmer Group umbrella since October 2020, with BSB acting as the primary component supplier to BWB and Ernst Klimmer GmbH supplying tooling in return, while HMT Häseler Metall Technik GmbH provides cleaning and surface technology services. Customers are industrial OEMs in rail vehicles (Deutsche Bahn-qualified), commercial/utility vehicles, machine and plant engineering, agricultural technology, construction, and the chemical industry, served through direct enterprise sales relationships, quote-based custom pricing, multi-year supply contracts, EDI/AX4-based logistics, and stock availability of standardized EC and DIN-compliant compressed air tanks.

Revenue is generated almost entirely through hardware sales of custom and standardized metal components and pressure vessels, with a small professional-services stream from in-house coating and quality testing. The combined business dispatches to 710 locations across 26 countries (BWB) and 238 locations across 12 countries (BSB), supported by approximately 4,000 tonnes of raw material storage, 5,000 pallets of semi-finished and finished goods, and a 13,000-location automated small parts warehouse. There is no external investor or private equity ownership disclosed; the company is owned and led by Managing Partner Torsten Klimmer alongside Commercial Director Wolfgang Laurer and Technical Director Oskar Hennig.

Core offering

BSB & BWB manufactures and supplies custom metal components and pressure vessels for industrial OEMs. BSB produces stamped and formed metal parts, welded assemblies, and laser-cut / sheet-metal components in steel, stainless steel, and aluminium, complemented by in-house surface coating and toolmaking. BWB designs and produces compressed air tanks (up to 800 litres) and oil separators with global pressure vessel approvals.

Product overview

BSB & BWB operates as two complementary companies under one roof within the Klimmer Group. BSB Metallverformung specializes in sophisticated punched and formed metal parts (up to 1,000 t compressive force, 0.8–16 mm sheet thickness), welding and laser technology, and coating services, serving as the group's leader in punching and forming technology. BWB Behälter-Werk focuses on compressed air tanks and oil separators (up to 800 litres volume) in steel, stainless steel, and aluminium with over 60 years of experience and global pressure vessel approvals. BSB acts as the main supplier of individual components for BWB, creating synergies from consulting and customized planning through manufacturing to logistics. The combined entity offers sheet metal working, bar machining, tool construction, quality management, and warehousing services.

• Kremsmüller Industrieanlagenbau KG: Austrian industrial fabricator specializing in pressure vessels, tanks, and welded assemblies for rail, chemical, and industrial customers. Direct overlap with BSB's stamping/forming and BWB's pressure vessel business in the German-speaking European market.
• Westfalia Metallschlauch GmbH: German specialized metal fabricator producing pressure-bearing metal hose and vessel components for industrial markets. Directly comparable to BWB's pressure vessel and BSB's welded assembly manufacturing capabilities.

Broad incumbents

• Benteler International AG: Austrian diversified metal processor with overlapping stamping, forming, and welded assembly capabilities across automotive, rail, and industrial customers. Operates at significantly larger scale than BSB & BWB but competes for similar European industrial OEM business.
• Voestalpine AG: Austrian integrated steel and metal processing giant with extensive stamping, forming, and special steel component capabilities across rail, automotive, and industrial markets. Much broader scope than BSB & BWB but overlaps in rail-certified component supply.

Others

• Schuler Group: German metal forming equipment manufacturer producing stamping, forming, and pressing machinery including the presses BSB uses. Equipment supplier and technology enabler for BSB's stamping and forming capability rather than a direct product competitor.
• Bystronic AG: Swiss manufacturer of laser cutting, bending, and automation equipment used in sheet metal fabrication shops like BSB. Equipment supplier providing enabling technology rather than direct competition in pressure vessels or stamped components.
