ArcelorMittal Flat Carbon Europe : committed to safety, sustainability and competitiveness Providing safe, sustainable steels are key values for ArcelorMittal. So it’s only natural that the world’s leading provider of flat carbon steels is active in the development of safer steel solutions for road safety equipment. Over the past ten years, ArcelorMittal has developed a full range of products and specific services to help our customers become more competitive and constantly improve the performance of their steel solutions. An opportunity for more competitive safety barriers Reducing the...

ArcelorMittal’s High Strength Low Alloy (HSLA) steels increase competitiveness by up to 20% Using ArcelorMittal’s High Strength Low Alloy steels enables safety barrier manufacturers to increase competitiveness by between 15 and 20% thanks to: Controlled properties HSLA steels have much tighter tolerances than structural steel grades. Their mechanical properties are more controlled than those of structural steels, providing better test result reliability and optimal safety. Tailor-made solutions The combination of different steel qualities enables barrier makers to design tailor-made...

Magnelis® ensures durability for the entire lifecycle of steel barriers ArcelorMittal offers a full range of coating solutions to protect steel safety barriers against corrosion. These include heavy gauge hot dip galvanising, as well as new high performance metallic coatings such as Magnelis®. 1 month 2 months 5 months Comprising a distinctive metallic chemical composition of zinc with 3.5% aluminium and 3% magnesium, Magnelis® lasts much longer than traditional coatings such as hot dip galvanization. The excellent corrosion behaviour of Magnelis® has been proven in outdoor tests. Magnelis®...

Safety barrier by Mieres Tubos/Grupo Condesa coated in Magnelis® ZM310 (steel thickness 3 mm). Exposure was started outdoors in September 2011 (left). Note the self-healing effect on the perforations in October 2013 (right). Tests have proven that Magnelis® has superior corrosion resistance in soils compared to zinc-heavy coatings. Magnelis® is more stable than conventional coatings when it is buried in the soil and results in less zinc run-off to the soil. Magnelis® is the best coating material to resist corrosion in various soil types. Benefits of using Magnelis® ArcelorMittal offers a...

ArcelorMittal’s co-engineering helps clients win in the marketplace ArcelorMittal’s Global R&D teams support our customers at all stages in the development of new solutions. Our assistance starts with the design of the first components and extends to the launch of the product on the market. To help our customers achieve their goals, ArcelorMittal has developed extensive knowledge of numerical analysis and experimental tests. We also have a deep understanding of safety standards and lightweighting thanks to our many years of experience in the automotive market. ArcelorMittal’s expertise is...

Safety barrier design To save lifes, roadside restraint systems are designed to: • Stop vehicles rolling over • Redirect errant vehicles back to the road after a crash with an exit trajectory which avoids collisions with other vehicles on the road • Gently decelerate the vehicle to minimise the severity of an impact on people and vehicles. All of the following elements interact during an impact and have an effect on barrier performance: • Barrier (beams, posts, spacers, junctions) • Vehicle and its occupants (structural elements, steering system, suspension system) • Road and its...

What can ArcelorMittal provide to barrier makers ? ArcelorMittal Global R&D can provide barrier makers with numerical and experimental tests including: • Steel characterisation • Investigation of beams and beam connections • Pull-out tests and optimisation of the beam/spacer connection • Soil characterisation • Post length and geometry optimisation • Transmission of energy to bridge decks. A comprehensive approach to barrier testing The behaviour of a barrier and its elements can be tested in several ways at ArcelorMittal’s facilities. Experimental results are used to check the accuracy of...

Case studies Anticipating the influence of soils Your barrier in six months Different soil types affect the working width of safety barriers and can influence their containment level. ArcelorMittal Global R&D is developing highly detailed soil models so we can predict this behaviour. Experimental tests form the basis of our advanced and reliable numerical models. In less than half a year, ArcelorMittal has helped a customer to design a more competitive safety barrier using the appropriate combination of high performance steels. The following savings were achieved with the new H1 barrier...

Sustainability is part of our values Steel is fully and permanently recyclable and is the most recycled material globally. All recovered steels are recycled. Steel can be recycled indefinitely without loss of properties and can be up-cycled to produce steel with superior performances. ArcelorMittal develops and manufactures environmentally friendly steels which offer: • Lead-free metallic coatings • Reduced material consumption thanks to the use of advanced High Strength Low Alloy steels • Zinc-aluminium-magnesium metallic coatings such as Magnelis® which reduce zinc run-off into soils and...
