What SENN AG does

SENN AG is a privately held Swiss industrial company founded in 1957 and headquartered in Oftringen, Switzerland, operating across five integrated service divisions: steel construction (Stahlbau), metal construction (Metallbau), sheet metal processing (Blechtechnik), emergency power systems (Notstromanlagen), and crane & heavy-transport services (Kran & Transport). The company employs over 200 staff (headcount band 251–500) under family-controlled ownership, with Heinz Senn as President of the Board and multiple Senn family members in divisional deputy-CEO and department-head roles. Customers are predominantly Swiss municipalities, construction firms, infrastructure projects, and industrial enterprises, with European delivery available through the online shop.

The company's technical capabilities center on EN 1090-2 EXC4 welding certification (the highest execution class for steel structures), EN 1090-3 EXC3 for aluminum, ISO 9001 quality management, MINERGIE window certification, and AM Suisse fire-protection credentials. Fabrication uses CNC equipment with laser cutting up to 2,000 x 6,500 mm, bending to 6,000 mm, and certified welding (TIG, MIG/MAG, spot, robot, laser, stud). Project planning is anchored by 35+ years of BIM-compliant factory planning using database-based 3D CAD systems. Vertically integrated assets include a fleet of mobile cranes (53–100 mt), heavy-transport vehicles capable of 250-ton exceptional loads, and a 761 kWp rooftop solar array commissioned November 2023 that powers operations. All steel is sourced as 100% recycled material from Swiss and European mills.

SENN AG generates revenue primarily through project-based B2B contracts across its service divisions — custom steel and metal construction, bridge and infrastructure builds, precision sheet-metal contract manufacturing, heavy-transport and crane rental — complemented by an e-commerce online shop (operated jointly with SEBA Engineering AG) selling standardized products in CHF with 2–3 day delivery across Switzerland and Europe. Customer acquisition is sales-led via dedicated account managers per division, supported by a corporate website, a digital Kranfinder tool, and a mobile app.

Direct peers

• H. Wetter Stahl- und Metallbau AG: Swiss steel and metal construction firm offering custom fabrication, structural steel, and metalwork services — a direct head-to-head competitor in the same Swiss specialty trade segment as SENN AG.
• Josef Meyer Stahl und Metallbau AG: Swiss steel and metal construction company providing structural steel, metalwork, and project-based fabrication — highly comparable in service portfolio, customer base, and Swiss operating geography.
• Stahlbau Feldmann GmbH: German steel construction and metalwork specialist serving bridges, halls, and industrial buildings — comparable in project types, EN 1090-class fabrication, and turnkey delivery model.
• Hans Künz GmbH: Austrian crane and heavy-haul specialist with own fleet, comparable to SENN's Kran & Transport division in service mix (cranes, exceptional transports) and target customers in industrial and energy projects.

Broad incumbents

• Felbermayr Holding GmbH: Larger European heavy-transport, crane, and construction-services group operating across DACH — overlaps with SENN's Kran & Transport offering but at meaningfully greater scale and geographic breadth.
• Marti Holding AG: Major Swiss construction group with steel and infrastructure divisions — overlaps with SENN's steel construction and bridge work, but operates at far greater scale across the full construction value chain.
• Implenia AG: Switzerland's largest construction services group, listed on SIX; competes with SENN on large infrastructure and bridge projects though from a much broader general-contractor position.
• Walo Bertschinger AG: Swiss construction group with civil engineering and infrastructure capabilities — competes on public-sector projects in the same Swiss market, though with a broader service portfolio.

Regional players

• ROBA Transport AG: Swiss heavy-transport and crane company with comparable specialty services (heavy lifts, exceptional transports) — directly comparable in crane/transport niche but geographically overlapping with SENN rather than competing abroad.
• Pfeifer Timber GmbH: DACH-based engineered timber and steel products supplier serving construction and infrastructure — adjacent rather than direct overlap, but comparable in supplying certified structural components to European builders.
