The weathering steel has been widely applied to bridges in the developed countries in Europe, America and in Japan owing to its good corrosion resistance behavior and life-cycle costing.

The coconut-based alternative also lasts longer, needs less frequent replacement, and has lower overall lifecycle costs compared to the conventional options on the market.
