What Lockwood Partners does

BUHLMANN Group is a family-owned German premium steel products trading company founded in 1945 and headquartered in Duisburg, with approximately 2,000 employees worldwide. The company distributes steel pipes, pipe fittings, flanges, and accessories across carbon, alloy, and stainless grades, available in DIN, EN, ASTM, ASME, and API standards, serving customers in the energy, chemical, shipbuilding, and machine construction sectors. Its core operational infrastructure centers on the Duisburg hub, which houses the proprietary Automatic Pipe Storage System (ARL) and Small Parts Warehouse (AKL) for automated inventory management, alongside a digital showroom platform (BUHLMANN-Port) for online product browsing. Since 2024, the group has expanded beyond pure trading into manufacturing via the acquisition of LISEGA Group, a leading industrial pipe support systems manufacturer, and in 2025 acquired Herregods-Franssen to extend distribution into the Benelux and France markets.

Revenue is generated through direct B2B sales of physical steel products from extensive stock inventory to industrial customers in pipeline, plant, and power plant construction, operating on a quote-based pricing model with multi-year contracts. GTM is enterprise field sales targeting engineering and procurement decision-makers in heavy industry, supported by a quarterly customer magazine (B) GLOBAL, webinars, and digital showroom content. Customer engagement is project-driven, with named reference projects spanning geothermal energy in Southern Germany and the Neptun Deep offshore project in the Black Sea. The business holds ISO 9001, ISO 14001, and ISO 45001 certifications and has published a Corporate Social Responsibility brochure, positioning certified quality and sustainability as procurement differentiators.
