It covers steel products, such as hot-rolled structural steel sections, steel plate, and hollow structural steel sections, that are hot dip galvanized after fabrication by members of the GAA. As such, it represents the industry average for members of the GAA. 

The declared unit for the EPD is 1 year of protection of a 1 m2 coated 8 mm thick steel plate. The scope is ‘cradle-to-gate with options’ covering production, transport to customer, end of life and recycling potential. A guide is provided to adjust the average EPD and apply it to align with specific product. 

The average impact of the hot dip galvanizing process, excluding the steel data, is also listed. This enables users to take EPD data for a specific steel product and calculate a more accurate environmental impact of the galvanized product.
