Schlagenhauf GmbH

What Schlagenhauf GmbH does

Schlagenhauf GmbH (DBA: Elektro Schlagenhauf) is a family-owned German electrical installation company headquartered in Ellwangen, Baden-Württemberg, founded on 24 April 1956 by Karl Schlagenhauf and currently represented by second-generation owners Lisa Schlagenhauf and Susanne Schlagenhauf. The firm operates five integrated service divisions — Starkstrom (high-voltage electrical installation), Schwachstrom (low-voltage, telecommunications, IT networking, security, fire/intrusion alarms), KNX building automation, Verkehrslenktechnik (traffic control systems including retractable bollards and barriers), and E-Check/Wartung (inspection, thermography, and ongoing maintenance) — supported by in-house CAD-based project planning and a structured subcontractor network used to scale capacity on large projects. The company's underlying technology is conventional industrial electrical and building-automation engineering, with KNX, VDS, and ISO 9001 certifications serving as gatekeeping credentials for public and enterprise tenders.

The firm sells exclusively on a project-quotation basis to enterprise and public-sector clients across Germany, with a strong footprint in Baden-Württemberg but nationwide reach. It acquires work through competitive public tenders, direct engagement with general contractors, project owners, architects, and facility managers, and referrals from an established reference list that includes Trumpf, B. Braun, Airbus Defence and Space, GEMÜ, dm-Drogeriemarkt, ZF Friedrichshafen, Intersport, Neue Messe Stuttgart, Landratsamt Ulm, Spielbank Berlin, and Ostalb-Klinikum Aalen, among others. Revenue mix is predominantly one-time project installation supplemented by recurring maintenance and service contracts; pricing is not publicly disclosed. The company employs approximately 200 staff and is privately held with no external investors, no M&A history, and no disclosed funding rounds.

Broad incumbents

• Siemens AG: Siemens' Smart Infrastructure division supplies building automation, low-voltage power distribution, and security systems that intersect with Schlagenhauf's KNX and Starkstrom scope. As a global incumbent with deep German roots, it defines the upper bound of competition for sophisticated commercial projects.
• ABB AG: ABB is a global electrification and automation conglomerate whose German operations span electrical products, drives, and building systems integration. While much larger, ABB's smart-building and KNX-adjacent product offerings overlap with Schlagenhauf's KNX automation scope.
• Schneider Electric SE: Schneider Electric is a global specialist in energy management and automation with deep KNX ecosystem presence through brands like Wiser and SpaceLogic. Its smart-building technology stack competes with and enables Schlagenhauf's KNX integration services.
• SPIE GmbH: SPIE is a major European technical services group with significant German electrical contracting operations serving commercial, industrial, and public-sector clients. While much larger and multi-disciplinary, SPIE is a direct reference point for how Schlagenhauf's service portfolio could scale within a multi-region services platform.

Others

• Gira (Giersiepen GmbH & Co. KG): Gira is a leading German manufacturer of KNX-compatible building automation products including switches, sensors, and control systems. As a technology supplier whose products Schlagenhauf integrates in its KNX projects, Gira is an adjacent ecosystem player rather than a direct competitor.
• Hager Group: Hager is a Franco-German electrical products manufacturer with strong KNX/smart-building portfolio and a significant German market presence. It supplies distribution boards and building automation components that Schlagenhauf installs, making it an adjacent technology partner rather than a direct competitor.
• Obeta Elektro Großhandel GmbH: Obeta is a German electrical wholesale cooperative serving thousands of independent electrical contractors, including installers like Schlagenhauf. It is an ecosystem partner rather than a direct competitor, but reflects the structure of the German electrical contracting supply chain Schlagenhauf operates within.

Direct peers

• EAB Elektroanlagenbau Rhein-Main GmbH: EAB is a Frankfurt-based mid-sized electrical contractor serving commercial, industrial, and infrastructure clients across the Rhine-Main region. Its scope and customer mix closely mirror Schlagenhauf's positioning as a regional full-service electrical contractor.
• ROM Technik GmbH & Co. KG: ROM Technik is a German electrical services firm delivering Starkstrom, Schwachstrom, and building automation for industrial and commercial customers. Its multi-trade service portfolio and German regional footprint make it a relevant comparable for Schlagenhauf's integrated offering.
• Elomech Elektroanlagen GmbH: Elomech is a mid-sized German electrical contractor with comparable scope across commercial, industrial, and public-sector projects. Headquartered in Mettmann, it operates across multiple German regions and is a closely comparable peer in size and service offering to Schlagenhauf.
