The EPD provides an industry average environmental impact of hot dip galvanized steel in Australia conforming to the requirements of AS/NZS 4680. 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 scope is ‘cradle-to-gate with options’ covering production, transport to customer, end of life and recycling potential.
The declared unit for the EPD is “1 year of protection of a 1 m² coated 8 mm thick steel plate”. As this declared unit is somewhat complicated, GAA provides a guide to adjust the average EPD results and apply it to align with a 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.
Through the publication of this EPD, GAA provides important insights into the environmental impacts and benefits of hot dip galvanizing, allowing its members and the broader construction sector to better assess its products. Congratulations to all involved!
start2see is proud to have assisted GAA with the verification of its LCA and EPD.
