What Stahlbau Schauenberg does

Stahlbau Schauenberg GmbH is a family-owned German steel construction and industrial plant construction firm headquartered in Kirchzarten, Baden-Württemberg, founded in 1958 and currently led by managing shareholders Dr. Harald Schauenberg and Dr. Guntram Winterhalter. The company engineers, fabricates, and assembles heavy steel structures for chemical plants, petrochemical refineries, ethylene/olefin/hydrogen facilities, air separation plants (Coldboxes), power plants, and industrial/commercial buildings. Its core technology stack combines simultaneous 3D-CAD engineering across four offices (Kirchzarten, Ihringen, Příbram, Tehran), CNC-controlled fabrication, modern welding certified to DIN EN 1090 and DIN EN ISO 3834-2, and a Computer-Integrated Manufacturing (CIM) data backbone linking production sites.

The firm operates an integrated service model spanning detail engineering, fabrication, corrosion protection, centrally controlled worldwide transport logistics, and own on-site assembly — all under one roof. Production capacity is 20,000 to 25,000 tonnes of steel per year across six production sites in Germany, Czech Republic, and Iran, with single-plant deliveries of up to 7,500 tonnes for process and refinery oven projects. The company holds ISO 9001:2015, DIN EN 1090 (factory production control and welding), DIN EN ISO 3834-2, and SCC safety certifications, which are mandatory qualifications for large EU industrial plant tenders.

Go-to-market is sales-led and project-based, targeting large international industrial investors in the chemical, petrochemical, and energy sectors. The customer base disclosed includes Evonik, Covestro, and Wacker Neuson. Revenue is generated through individual project contracts rather than recurring licensing or SaaS arrangements; pricing is not publicly disclosed and contracts are quoted per project. Distribution is direct enterprise sales with field engagement and assembly teams deployed to customer sites, complemented by a corporate website, regional press coverage, and trade fair presence. The firm has three wholly-owned subsidiaries (Wilhelm Schauenberg GmbH in Ihringen, Halex-Schauenberg ocelové konstrukce s.r.o. in the Czech Republic, Schauenberg Iberica S.L. in Spain) plus an engineering office in Tehran, giving it a four-country European/Middle Eastern footprint.

Core offering

Stahlbau Schauenberg is a steel construction and industrial plant construction firm that engineers, fabricates, and assembles large-scale steel structures for chemical plants, petrochemical refineries, air separation units, and power plants. Services span detail engineering using 3D-CAD, CNC-controlled manufacturing, modern welding, corrosion protection, worldwide transport logistics, and on-site assembly delivered as integrated project contracts.

Product overview

Stahlbau Schauenberg is a steel construction and industrial plant construction company offering a comprehensive portfolio of services centered on plant construction (Anlagenbau) and industrial/commercial construction (Industrie- und Gewerbebau). The company operates as a single unified service provider rather than a platform-plus-modules architecture. Their core offerings include specialized process and refinery ovens (Prozess- und Raffinerieöfen) as heart components for chemical plants, chemical plant steel construction (Chemieanlagen), air separation plants (Luftzerlegungsanlagen/Coldboxen), and power plant construction (Kraftwerke). These are complemented by core steel construction services with detail engineering, CNC-controlled manufacturing, welding, corrosion protection, and their own assembly teams. The company integrates its services from engineering through manufacturing to worldwide assembly delivery.

Products and services

• Process and Refinery Ovens (Prozess- und Raffinerieöfen) Specialized ovens serving as core heart components of petrochemical facilities, including ethylene plants, olefin plants, and hydrogen plants. Delivered in sizes of up to 7,500 tonnes per plant for chemical industry operators.
• Chemical Plants (Chemieanlagen) Steel construction for chemical plant facilities combining computer-coordinated manufacturing with intelligent networking of international subsidiaries for cost-effective production and short delivery times. Includes projects for operators such as Evonik and Covestro.
• Air Separation Plants / Coldbox (Luftzerlegungsanlagen) Air separation units in which ambient air is liquefied at temperatures down to -180°C and separated into nitrogen, oxygen, carbon dioxide, and noble gases. Includes engineering, delivery, and assembly of stainless steel-framed boxes housing separation columns.
• Power Plants (Kraftwerke) Steel construction for power plants serving both municipal and industrial investors. Delivered via sophisticated logistics from engineering through manufacturing to maritime packaging, using a kit principle for fast on-site assembly.
• Industrial and Commercial Construction (Industrie- und Gewerbebau) Comprehensive industrial building services beyond classical steel construction, covering the entire spectrum of industrial construction to individual customer specifications, including branch facilities for industrial customers such as Wacker Neuson.
• Steel Construction Services (Stahlbau) Core steel construction services covering detail engineering, CNC-controlled manufacturing, modern welding technology, corrosion protection, and worldwide transport logistics delivered as an integrated package.
• On-site Assembly (Montage) Own assembly teams with worldwide experience performing installation work within operating industrial plants, providing maximum flexibility and on-time delivery on customer sites.

Expansion highlights5 records

Direct peers

• Donges Group GmbH: German steel construction group specializing in bridges, industrial buildings, and structural steelwork across Europe. Closest direct peer to Schauenberg in terms of scale, end-market focus on industrial plant and infrastructure steelwork, and vertical integration from engineering through fabrication.
• Stahlbau Nägele GmbH: Mid-sized German steel construction firm with similar project-based industrial plant and commercial building focus. Comparable in headcount, customer type, and reliance on certified welding/EN 1090 manufacturing, making it a direct mid-market peer.
• Echterhoff Bau GmbH: German construction company with dedicated steel and industrial construction capabilities serving similar chemical, petrochemical, and energy plant clients. Direct peer based on industrial plant construction services and German Mittelstand scale.
• Heberger GmbH: German industrial and commercial construction firm with in-house steel fabrication and plant construction services, frequently engaged on chemical and industrial plant projects. Direct peer given comparable customer mix and project delivery model.
• Wayss & Freytag Ingenieurbau AG: German heavy construction specialist covering bridges, tunnels, and complex industrial structures. Relevant peer for high-spec structural steel projects in plant and infrastructure settings, though typically larger and more civil-engineering focused.
• Exyte GmbH (formerly M+W Group): German-headquartered global high-tech facility and plant construction specialist serving semiconductors, pharmaceuticals, and chemical/industrial clients. Direct competitor for complex industrial plant construction, particularly in process-driven facility builds with high quality and certification requirements.

Regional players

• Tensacciai S.p.A. Italian structural steel fabrication specialist serving industrial plants, energy infrastructure, and large commercial buildings across Southern Europe. Comparable in product offering and certification profile; geographically distinct from Schauenberg's German/Czech/Iran footprint.

Broad incumbents

• Bilfinger SE: Large German-listed industrial services group providing maintenance, engineering, and construction services to chemical, petrochemical, and energy customers. Overlaps with Schauenberg on industrial plant steel construction and assembly but serves a much broader scope with significantly greater scale.
• HOCHTIEF AG: One of Germany's largest construction groups with significant industrial and commercial building capability. A broader incumbent that competes for large industrial plant projects but is not specialized in the niche steel fabrication Schauenberg occupies.
• STRABAG SE: Austrian-headquartered European construction major with extensive industrial and infrastructure capabilities. Adjacent competitor for large plant and industrial construction contracts; much larger and more diversified than Schauenberg.
