Magnelis® adds to durability of safety barriers

Together with Chilean manufacturer Tecnovial, ArcelorMittal’s Global R&D division has recently completed the development of a road safety barrier. The new barrier utilises high strength steel from ArcelorMittal and our unique Magnelis® coating to provide durable solutions for Chile’s roads.

The Chilean road authority Ministerio de Obras Públicas (MOP) has implemented several initiatives to improve road safety within the South American country. One of first was the adoption of the European standard (EN 1317) for safety barriers on the Chilean road network.

Tecnovial and ArcelorMittal: long-term partners

Tecnovial, a long-term customer of ArcelorMittal South America, is one of the main manufacturers of road safety barriers in Chile. To meet the new requirements, Tecnovial needed to develop a high-containment (H2 level) barrier system which can contain and redirect vehicles weighing up to 13 tonnes.

Tecnovial approached ArcelorMittal to help them develop the H2 barrier solution. “ArcelorMittal already has experience with the EN 1317 standard and with Tecnovial,” notes Horacio Pinochet Vejar, general manager of Tecnovial. “We are also aware of their high strength steel offer and the benefits of Magnelis®. Together this made ArcelorMittal the ideal partner for the project.”

Technical development of the new barrier solution was carried out by CRM Group’s AC&CS (Advanced Coatings & Construction Solutions) department, a strategic partner of ArcelorMittal’s Global R&D division. During the development process AC&CS relied on Tecnovial’s experience in safety barrier production to design a cost-effective solution that fits the requirements of the Chilean market.

“We selected ArcelorMittal’s high strength steel grade S420MC for the new barrier,” explains Claudia Cofano, project leader for AC&CS. “The decision to use high strength steel allowed us to design a lighter, more competitive product which is also visually appealing and very easy to install.”

A big step forward for road safety in Chile

ArcelorMittal recommended that the high strength steel used in the new barrier should be coated with Magnelis®, a unique protection solution which can extend the life of safety barriers significantly.

Once the design of the barrier was completed, AC&CS used advanced calculation tools to numerically test various impact scenarios. An 80-metre section of the barrier then underwent tests at the CSI crash-test centre in Bollate (Italy).

Tecnovial has already introduced its new H2 safety barrier on the Chilean market. The combination of high strength steel, Magnelis®, and European certification is leading to widespread interest in the new barrier across Chile.

The TB51 test verifies that the barrier can safely contain a 13-tonne bus crashing into the barrier at an angle of 20° and speed of 70 km/h
