Czech-based
ArcelorMittal Ostrava, a part of Luxembourg based global steelmaker
ArcelorMittal, has announced that it will start producing weathering steel at its medium and heavy section mill in Ostrava.
The higher content of copper in this type of steel provides a surface layer that protects the steel against atmospheric corrosion. The new product will be used for construction of bridges of open halls. It can last up to 80 years without needing maintenance and having to protect its surface by coating or painting.
The company stated that Ostrava will be the only manufacturer in the Czech Republic producing weathering steel sections.
