Corrosion protection systems: an environmental comparison

Both hot dip galvanising and paint are used as corrosion prevention systems for steel structures. A study by the Technical University at Berlin, Germany consisted of a life cycle assessment of a paint coating (EN ISO 12944) and hot dip galvanising (EN ISO 1461). The two systems had to provide corrosion prevention for a steel structure, that was to be used for 60 years, and which was applied to a steel structure such as a multi storey car park with a steel area of 20 m2/t. It was assumed that the structure was externally exposed to a medium level of corrosion. The environmental impacts of the two systems were compared with respect to resource consumption, greenhouse effect, photooxidation formation, acidification, and eutrophication. The hot dip galvanising system had a lower environmental impact compared with the paint system.
