Lourido Wire Bridge restoration with Ø75 mm FLC cables

Cables Estructurales supplied the Ø75 mm GALFAN-coated galvanized steel FLC (Full Locked Coil) cable systems for the comprehensive restoration of the iconic Ponte de Arame do Lourido (Lourido Wire Bridge). A civil engineering solution ensuring both aesthetic preservation and long-term structural safety for this century-old suspension bridge.

Technical Highlights & Solution Provided

• Ø75 mm FLC cables: Closed cable technology providing high structural stiffness and minimizing elongation under tension.
• GALFAN anti-corrosion protection: Zinc-Aluminum alloy coating that significantly increases resistance to moisture and weathering compared to standard galvanizing.
• Guaranteed watertightness: Interlocking profile wire geometry prevents water ingress into the cable core.
• Heritage preservation: Seamless integration that maintains original visual lightness and architectural identity in compliance with modern standards.
