Two newly rebuilt sections of the Czech Republic’s D1 motorway will be equipped with safety barriers manufactured by ArcelorMittal Ostrava, using the company’s revolutionary Magnelis® coating.

A total of 900 tonnes of one and two-way traffic barriers will be installed between June and November this year. 

“We will install the safety barriers at two newly reconstructed sections of the D1 motorway, from Jihlava to Velký Beranov and from Velká Bíteš to Devět křížů. Together, there will be 23 kilometres of one and two-way safety barriers with the Magnelis® coating, which represents roughly 900 tonnes of this product. Apart from the D1 motorway, we have already installed the same safety barriers on the I/11 road“ said Dagmar Raszková, safety barriers sales manager at ArcelorMittal Ostrava.

Magnelis® coating offers a revolutionary new form of steel corrosion protection. Compared with the standard zinc coating, the protective layer of Magnelis® is four times thinner, with its 25µm thickness sufficient for corrosion protection. The Magnelis®  coating protects the steel barrier for twice as long - up to 40 years. This is enabled by the unique chemical composition which, besides zinc, also includes aluminium and magnesium. Thanks to the high durability and adhesion of the coating, the steel can be shaped using different methods of forming including bending, drawing and profiling. 

“Apart from its durability, the most important added value of the Magnelis® coating is its self-healing capability. It perfectly protects the areas that are most easily attacked by corrosion such as cuts, welds and scratches. When the protective layer is damaged, Magnelis® can repair itself and extend the life of the entire steel safety barrier system,” explains Raszková. Magnesium forms a protective film over the damaged area to protect it against the weather and corrosion. 

ArcelorMittal Ostrava has been making safety barriers since 1969, producing almost 45,000 kilometres of safety barriers during this time. ArcelorMittal Ostrava is the only producer of safety barriers in the ArcelorMittal Group. More than 80% of higher class roads and motorways in the Czech Republic are equipped with safety barriers made in Ostrava.
