Steuler-Gruppe

What Steuler-Gruppe does

Steuler-Gruppe is a German family-owned industrial group headquartered in Höhr-Grenzhausen and founded in 1908, with reported annual revenue of €411 million and 2,400+ employees. The group operates two principal businesses: STEULER-KCH GmbH, which designs and manufactures industrial corrosion-protection linings (acid-resistant brick and tile, rubber, plastic/BEKAPLAST, and refractory linings) for chemical, petrochemical, steel, and waste-processing infrastructure; and Steuler Anlagenbau GmbH & Co. KG, which engineers custom environmental-technology plants covering flue gas treatment (DeSOx, SCR denitrification catalysts, wet electrostatic precipitators), zero-liquid-discharge pickling systems, and CO2 fertilization for horticulture. Underlying technology is proprietary, including patented self-supporting ceramic STEULER-domes for reaction towers (1975), the styrene- and solvent-free OXYDUR iVE vinyl ester resin system (2020), the BEKAPLAST mechanically anchored thermoplastic lining (1970), and high-temperature tunnel kilns reaching 1,650°C with single-line capacity of up to 16,000 tons/year of premium refractory product.

The business model is project-based enterprise sales delivered via direct field-sales professionals and a network of 25+ wholly-owned subsidiaries plus representative partners across Europe, the Americas, Asia-Pacific, the Middle East, and Africa, serving 80+ countries. End markets are concentrated in chemical and petrochemical operators (BASF and Bayer are named customers), ceramics and building materials manufacturers, steel and non-ferrous metal processors, waste and recycling operators, the horticulture sector, and emerging battery/EV manufacturing facilities. Revenue is generated through one-time licenses/sales of engineered lining systems and complete plant contracts that bundle consulting, engineering, manufacturing, installation, and after-sales service; pricing is quote-based and not publicly disclosed. Approximately 2% of revenue is reinvested in R&D each year.

Following the 2023 insolvency-driven divestiture of its historical consumer-tiles business, the group has actively refocused and expanded its core industrial footprint via the 2022 acquisition of UK/Ireland-based Ancorite Holdings Ltd., greenfield subsidiaries in Turkey (2024) and the USA (Steuler Linings Corp., Chicago, 2026), a new trading company in China (2025), continued product development (KERA DUROSTRONG, 2025), and a EUR 3 million 2026 production-hall investment at Siershahn. The group is led by an Authorised Managing Director (Michael Steuler) reporting to a Supervisory Board chaired by Jürgen Grimm, with division-level management at both STEULER-KCH and Steuler Anlagenbau. Sustainability positioning is supported by ISO 9001/14001/50001 certifications, DIBt and TÜV approvals, an internal Code of Conduct, a Declaration of Sustainability, and a first-time EcoVadis Bronze Medal awarded to STEULER-KCH in 2026.

Core offering

Steuler-Gruppe manufactures and installs industrial corrosion protection linings (acid-resistant brick, rubber, plastic, and refractory linings) and engineered environmental equipment (flue gas treatment systems, pickling plants, CO2 fertilization systems). The group serves chemical, petrochemical, steel, ceramics, horticulture, and pool construction customers with complete project delivery including consulting, engineering, production, installation, and after-sales service across 80+ countries.

Product overview

Steuler-Gruppe is a German industrial group offering two main business segments: Linings and Anlagenbau (Equipment Engineering). The Linings division provides industrial corrosion protection through Surface Protection Linings (acid-resistant brick and tile linings, rubber linings, floor/wall coatings), Refractory Linings (fire-resistant products including chrome corundum bricks and kiln furniture), Plastic Linings (BEKAPLAST thermoplastic systems, KERAVERIN FRP equipment, wet electrostatic precipitators), and Pool Linings (STEULER-Q7, BEKAPOOL, BEKAPLAST AQUA-LINING 400, AlphaLine). The Equipment Engineering division constructs environmental technology plants including CO2 fertilization systems, flue gas treatment (DeSOx, chemical scrubbers, maritime systems), surface technology (pickling plants), and catalytic systems. Key products include OXYDUR iVE (solvent-free vinyl ester resin system), KERA DUROSTRONG (FRP composites), BEKAPLAST/BEKASTEEL (lining systems), and wet electrostatic precipitators. Founded in 1908, the company operates globally with over 2,400 employees across 25 locations serving 80 countries.
