75 mm FLC Cables with GALFAN Coating for the Rehabilitation of Ponte de Arame do Lourido
The rehabilitation of historic bridges demands a balance between heritage conservation and state-of-the-art civil engineering technology. At Cables Estructurales, we participated in the renovation of the iconic Ponte de Arame do Lourido, a century-old infrastructure upgraded to guarantee its safety and long-term durability. For this project, we supplied our 75 mm FLC (Full Locked Coil) cable systems, manufactured in galvanized steel with a GALFAN coating to ensure maximum resistance in exposed environments.
Advantages of FLC (Full Locked Coil) Cables with GALFAN Coating
The use of advanced FLC locked-coil cables represents the best choice for high-demand suspension and cable-stayed bridge rehabilitations:
- Superior Corrosion Protection: The GALFAN alloy coating (Zinc-Aluminum) offers exceptionally high durability against harsh atmospheric agents and moisture, vastly extending service life compared to traditional galvanizing.
- Watertight Geometry and High Stiffness: The interlocking shaped-wire structure of the Full Locked Coil system reduces water ingress into the cable core and minimizes structural stretch under load.
- Long-Term Structural Safety: Ensures uniform tension distribution, which is essential for maintaining the overall stability of historic infrastructure.
How to Rehabilitate Historic Suspension Bridges While Ensuring Safety?
Replacing the stay systems on historic suspension bridges requires swapping old cables for advanced, large-diameter FLC solutions (such as Ø75 mm). This technology preserves the bridge’s original aesthetic and visual lightness while delivering a level of mechanical strength and reliability that meets modern structural codes.
High-Engineering Solutions for Bridges and Infrastructure
As specialists in developing tensile elements for civil engineering, we tailor our technology to the specific requirements of every project:
- Premium Materials: We supply cables with cutting-edge metallic treatments designed to withstand weathering without losing mechanical properties.
- Specialized Technical Consulting: Our engineering department supports contractors and consultants in selecting the optimal cable system for both retrofits and new builds.
- Custom Solutions: We design and manufacture bespoke cables and components tailored to project loads and the specific geometric constraints of the infrastructure.
