Rust from bay bridge shows dangers of corrosion

Engineers have excised a steel anchor rod from the eastern segment of the San Francisco Bay Bridge to test its structural integrity. Tests performed on the anchor rod revealed deterioration to the structure that may be indicative of even more extensive damage. That deterioration could pose a tremendous safety hazard to the icon of the Bay area and its infrastructure. These tests bring the future of the bridge into doubt.

The anchor rod is 25 feet long as part of a structure that is imperative to the foundation of the bridge. The engineering behind the bridge makes it impossible to remove and replace these components of the bridge. The possibility of massive reconstruction highlights the tremendous cost that addressing corrosion damage can have.

The damage done to the bridge was due to the wearing down of its zinc galvanization coating. Corrosion prevention technologies use protective coatings in order to prevent metal from oxidizing. However, the innovations made within these technologies did not exist during the bridge's initial construction. This issue is something that future infrastructure developments must take into account in order to extend the lifespan of these structures.

Infrastructure is not the only thing that faces damage from corrosion. Marine fleets, vehicles and oil refining equipment are just a few other things constantly exposed to the harsh conditions that can lead to corrosion damage. Corrosion testing equipment like salt spray chambers can allow businesses within these industries to test the durability of their equipment in order to improve its efficiency.
