What Schroeder does

Anker Schroeder ASDO GmbH is a privately held German manufacturer founded in 1920 and headquartered at Hannoverische Straße 48, 44143 Dortmund, specializing in heavy upset forging (Stauchschmiedeverfahren) of oversized steel tension members, round steel anchors, mooring bollards, heavy-lift shackles, and custom forged components for civil engineering, maritime infrastructure, and heavy mechanical engineering applications. Its core product line is the ASDO tension rod system, a building-authority-approved product family spanning nominal sizes M12 to M160, with round steel anchors produced in diameters up to 105/115 mm and lengths up to 29 meters, mooring bollards rated 50–3000 kN, and heavy-load shackles rated 40–1500 tonnes. CAD/BIM data for these components is published in formats compatible with AVEVA bocad and Tekla Structures, enabling structural engineers to specify ASDO products directly inside mainstream design workflows. The company has been ISO 9001:2015 certified since July 1, 2017.

The business model is direct enterprise B2B sales of custom-engineered, project-based hardware. Revenue is generated through one-off contracts with harbor authorities, port operators, engineering firms, construction companies, and heavy machinery manufacturers for large infrastructure projects; pricing is not publicly disclosed and is quoted per project specification. GTM is reference-driven, leveraging a project portfolio that includes Dublin Port, Liverpool 2, Felixstowe, London Gateway, Aqaba Container Port, Port Autonome Le Havre, Nigg Energy Park, Manchester City FC, Wolverhampton FC, Schnettkerbrücke Dortmund, London Cannon Place, the Tessenderlo cycling bridge, Madrid District Heating, and the Be'er Sheva University Bridge. The company maintains marketing channels centered on trade-show participation (notably WindEnergy Hamburg 2024), project case studies, CAD downloads, and direct sales consultation.

Anker Schroeder is classified into five core customer verticals: Maritime & Port Infrastructure (primary), Civil Engineering & Bridge Construction (primary), Heavy Mechanical Engineering (primary), Geotechnical Engineering, and Offshore & Lifting Technology. Geographic reach spans Germany, the United Kingdom, Ireland, France, Spain, Belgium, Jordan, Israel, and the United States. The company operates as a privately held GmbH with no identified parent company, no external investment backing, and no disclosed funding history; it has remained under independent ownership since 1920. The current workforce is approximately 21 employees.

Core offering

Anker Schroeder ASDO GmbH manufactures heavy upset-forged steel tension members and anchoring systems for civil engineering, water engineering, and heavy machinery applications. The company produces round steel anchors up to 29 meters long, tension rod systems from M12 to M160, mooring bollards rated 50–3000 kN, and heavy-lift shackles rated 40–1500 tonnes, serving harbor construction, bridge engineering, and industrial machinery sectors through custom-manufactured project-based contracts.

Product overview

Anker Schroeder ASDO GmbH is a manufacturer of large upset-forged steel tension members, operating as a single-product-line company whose portfolio centers on heavy anchoring and tensioning systems for civil engineering and industrial applications. The core product line consists of the ASDO Zugstabsystem (tension rod system, M12–M160), which anchors steel sheet pile structures and quay walls in water engineering, supports buildings and bridges in structural engineering, and serves heavy machinery and lifting applications. The portfolio is organized across five product categories: Wasserbau (Water Engineering — round steel anchors, connections, strakes, micropiles), Ausrüstungsteile (Equipment Parts — mooring bollards in 50–3000 kN ratings, welded constructions), Hochbau (Building & Bridge Construction — ASDO tension/compression rod systems, cross braces, tie rods, wind bracing), Schäkel (Shackles — heavy-load and offshore shackles rated 40–1500 t), and Schwermaschinenbau (Heavy Machinery — piston rod blanks, flange shafts, tie rods, special screws, bent components). CAD data downloads are available for the tension rod systems in 2D and 3D formats compatible with AVEVA bocad and Tekla Structures.

• Pfeifer Seil- und Hebetechnik: German manufacturer of wire rope, lifting, and tensioning systems. Overlaps with ASDO on tension members, threaded bars, and structural lifting hardware for construction and offshore applications.
• Macalloy: UK-based specialist in stainless and carbon steel tension bar systems for structural and architectural applications. Closely comparable on M-range tension rod systems for bridges, stadia, and buildings.
• DYWIDAG (DSi): Global supplier of post-tensioning systems, ground anchors, and reinforcement products for civil engineering. Directly comparable on tension members and geotechnical anchoring for bridges, ports, and heavy civil works.
• Williams Form Engineering: US-based manufacturer of ground anchors, tie rods, and post-tensioning systems for civil and geotechnical engineering. Comparable product portfolio for heavy civil and marine anchoring applications.
• Friedr. Ischebeck GmbH: German manufacturer of geotechnical and formwork systems, including ground anchors, micropiles, and tie rods. Directly comparable on the geotechnical / micropile product line and on heavy threaded anchoring.
• Stahlwerk Annahütte (Max Auer): German specialist in heavy forging and anchoring technology, including Gewi threadbars and anchor systems. Closest European direct peer on heavy upset-forged steel anchoring for marine and civil applications.

Broad incumbents

• Liebherr: Diversified heavy-equipment manufacturer whose offshore crane and maritime product lines use and compete with large forged anchoring and shackle systems. Broader incumbent rather than a focused specialist, but a credible competitor in the offshore mooring and heavy-lift segment.
