IBU (Institut Bauen und Umwelt e.V.) has published an Environmental Product Declaration (EPD) for single-sided road barriers made with high strength low alloy and structural steels coated in Magnelis®. The EPD covers barriers which are made from steel grades HX340LAD, HX420LAD, S250GD, or S350GD, with ArcelorMittal’s Magnelis® ZM310 metallic coating.
The EPD applies to one running metre of a single-sided barrier including the support post. The thickness of the steel ranges from 2.8 to 8.0 mm depending on the design.
The barriers covered by the EPD meet the H1W3A level of the EN 1317-2:2010 European standard for road restraint systems. H1 barriers are designed to contain a 10,000-kilogram vehicle travelling at 70 kilometres per hour. The EPD is based on data collected from ArcelorMittal’s mills in Bremen (Germany) and Ostrava (Czech Republic).
An EPD is an independent and transparent way of communicating about the environmental performance of a product or system. The content is derived from a life cycle assessment (LCA) and typically evaluates all phases of the product’s life including supply of the raw materials, production, and end-of-life recycling. The EPD also contains information about the energy use, efficiency, emissions, and waste generation during the product’s manufacture, service life, and recycling.
