Structures

Structural strand, stay cables, and post-tensioning systems for bridges, stadiums, and major structures.

Overview

Structural cables and strand systems are among the most demanding applications in civil engineering — carrying permanent loads measured in thousands of tonnes, exposed to weather and corrosion for decades, and installed with tolerances measured in millimetres.

WireCo, through Camesa, manufactures structural strand and cable products for cable-stayed bridges, suspension bridges, post-tensioned structures, and architectural applications. Our products are engineered for the specific fatigue, corrosion, and load distribution requirements of long-span infrastructure.

With project engineering support from concept through installation, WireCo delivers complete cable solutions — not just material supply — to structural engineers and contractors worldwide.

Key Challenges in Structures

The problems WireCo products are engineered to solve.

Decades-Long Fatigue Life
Structural cables on bridges and major structures must perform under continuous cyclic loading from traffic, wind, and thermal expansion for design lives of 50 to 100 years — with limited opportunity for replacement.
Corrosion in Exposed Environments
Stay cables and structural strand are permanently exposed to rain, humidity, salt air, and temperature extremes. Corrosion protection must be built into the cable system from the wire level up — not just applied as a surface treatment.
Precise Load Distribution
Cable-stayed bridges require uniform load distribution across multiple stay cables. Strand-to-strand and cable-to-cable load variation must be minimized during installation and maintained throughout the structure's service life.
Seismic & Wind Dynamic Loads
Structures in seismic zones or high-wind regions subject cables to dynamic loads well beyond static design values. Cable systems must absorb and dissipate energy without progressive fatigue damage.

How WireCo Delivers

01
Structural Strand Engineered for Infrastructure

Camesa structural strand is manufactured with high-strength galvanized wire and precisely controlled lay lengths that deliver consistent mechanical properties across the full cable assembly. Our strand products are designed for the specific load, fatigue, and corrosion requirements of bridges, stadiums, and post-tensioned structures.

02
Multi-Layer Corrosion Protection

WireCo's structural cable systems use a layered corrosion defense strategy — zinc-coated wires, strand fill compounds, HDPE sheathing, and anchorage sealing — that protects the cable system from the inside out. This approach extends service life well beyond the typical inspection intervals for exposed infrastructure.

03
Project Engineering & Installation Support

WireCo provides engineering support for cable system design, anchorage detailing, and installation sequencing. Our team works with structural engineers and contractors from the early design phase to ensure cable geometry, tensioning procedures, and load distribution meet the project specification.
