What is the life span of a Weathering steel bridge?

In suitable environments weathering steel bridges forms an adherent protective rust 'patina', that inhibits further corrosion. The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120-year design life with only nominal maintenance.

Corten Steel Foot Bridge

Weathering steel is a high-strength, low-maintenance and cost-effective solution for extending the service life of steel bridges - up to 120 years. It is a widely used corrosion protection system.

Corten steel structures are more economical in the long run, despite their higher upfront costs. They require less maintenance and are more durable than traditional building materials.

Corten Steel Garden Bridge

Garden steel bridges are best suited to spanning large distances and thus showing their full advantages. The bridges have supports every 12 meters (design on request). The maximum evenly distributed load capacity is 5 kN/m2 . The whole is made of robust Corten steel. Untreated or preservative treated. Foundations can be steel or concrete piles, depending on ground test results. Life expectancy: 50 years.
