The European General Galvanizers Association has published an Environmental Product Declaration (EPD) for ‘Batch Hot Dip Galvanizing of Steel Products to EN ISO 1461 – European Average’.
The EPD has been generated under the International EPD System® based on Product Category Rules for Corrosion Protection of Fabricated Steel Products and is independently third-party verified in accordance with ISO 14025:2010 and EN 15804.
Batch galvanizing is most often specified early in the design of steel components and structures with the coating application being sub-contracted much later in the supply process. For this reason, a sector-based EPD is the most informative approach for architects and designers when considering environmental information.
The EPD is based on a new Life Cycle Inventory (LCI) study carried out by Life Cycle Engineering srl (Italy) that collected detailed environmental information from 66 galvanizing plants producing over 1 million tonnes of coated steelwork in 14 countries. LCE worked closely with EGGA’s national associations to collate the sample. The sample was then carefully checked to be representative of the mix of technology used across the industry. The LCI data are fully comprehensive – covering every aspect of the galvanizing process, from raw materials to process energy and ancillary operations.
Results are presented for a notional 1m2 steel plate of 8mm section thickness. Environmental burdens of the galvanized coating are separated from that of the steel plate – to demonstrate that the additional burden of providing lifelong protection for steel components is extremely small.
The EPD is also mutually recognised by the IBU EPD system (Germany). Download the IBU version here. https://epd-online.com/PublishedEpd/Detail/9545
