What Carbo-Link AG does

Carbo-Link AG is a Swiss specialty manufacturer of Carbon Fiber Reinforced Polymer (CFRP) cables, tubes, and structural components, founded in 2001 and headquartered in Fehraltorf, Switzerland (with additional engineering and manufacturing operations in Bremerhaven, Germany). The company designs and manufactures custom-engineered CFRP solutions targeting bridge infrastructure, marine/yachting, industrial cranes, structural reinforcement, and aerospace applications. Its portfolio centers on the CL SOLID product family — bridge cables, crane cables, and yacht rigging — supplemented by CL ELLIPSE (yacht rigging profiles), CL RESTRAP (shear reinforcement), CL-CT (linkages and toggles), carbon spars, and truss/torque tubes. Underlying manufacturing leverages pre-pregnated carbon fibres, continuous windings around titanium pin thimbles, and AS9100D-certified aerospace-grade processes. The company has pioneered commercial deployment of CFRP tension elements in network arch bridges, executing the Stadtbahnbrücke (Stuttgart, 2020) and the Oderbrücke (Berlin-Kostrzyn, 2024) — the first and second such bridges globally to use its CL SOLID carbon hangers. The Oderbrücke is rated for 120 km/h train speeds, demonstrating applicability from light rail to mainline heavy rail.

Carbo-Link operates a project-based, custom-engineering B2B model. Customers and partners include German rail infrastructure entities (DB Netz AG, Stuttgarter Straßenbahnen AG), elite structural engineering firms (Schlaich Bergermann Partner, Knight Architects), research institutes (EMPA), and enterprise clients in marine and aerospace (Solar Impulse / Skydweller, racing yachts Sea Eagle and Leopard). Go-to-market is enterprise field sales with technical consultative selling — direct engagement with project developers, engineering firms, and government entities — rather than broad marketing. Distribution is direct (no channel partners), and revenue is generated through one-off manufacturing contracts with project-specific pricing (no published price list). Marketing is centered on technical case studies, industry awards, and certifications (DNV Type Approval, AS9100D, ISO 9001).

Products and services

• CL SOLID Bridge Cables Carbon fiber reinforced polymer (CFRP) bridge cables designed for network arch and cable-stayed bridge applications, with 150-year design lifespan, high stiffness (150-300 MN EA), and working loads up to 1,960 kN. Intended for public infrastructure owners and structural engineers.
• Yacht Rigging (CL SOLID) CL SOLID carbon fiber standing rigging solution for high-performance sailing yachts, providing high stiffness, fatigue resistance, and vibration damping. Targeted at yacht builders, naval architects, and racing teams.
• CL ELLIPSE Yacht Rigging Elliptical-profile carbon fiber rigging solution for yacht applications, combining aerodynamic/aesthetic profile with CL SOLID material performance and DNV Type Approval.
• Carbon Spars Carbon fiber spars for marine mast systems and structural applications, providing lightweight strength. Used in projects such as the Project Zero sailing yacht.
• CL RESTRAP Shear Reinforcement CFRP-based shear reinforcement system for strengthening existing concrete and structural elements, providing non-corrosive, lightweight, long-life reinforcement for infrastructure rehabilitation projects.
• CL SOLID Crane Cables CFRP crane pendant cables providing a super lightweight solution for heavy-lift and port cranes, capable of exceeding 200m lengths without fatigue or deformation, increasing crane payload capacity.
• CL-CT Linkages & Toggles CFRP basket loop toggle/link system cured into inline or offset interfaces for joining cables and tension members. Manufactured with pre-pregnated carbon fibres continuously wound around titanium pin thimbles, offering ultimate stiffness and no fatigue, with separable tension and torsional load paths.
• Truss & Torque Tubes Custom-engineered carbon fiber truss structures and torque tubes for aerospace and other advanced applications, providing ultra-lightweight high-stiffness load-bearing structures (deployed in Solar Impulse / Skydweller solar aircraft projects).
