First keep in mind that hot-dip galvanized steel is durable and maintenance free for 50-60 years or longer, so lifecycle costs are extremely compelling compared to alternatives. Due to the relatively stable price of zinc metal over the past 20 years, considering the initial cost of hot-dip galvanized plate girder and rolled beam steel for bridges is very competitive with the life cycle cost of painted steel.
