ArcelorMittal will temporary idle its EAF and two rolling mills at its long steel production site in Rodange and Schifflange, Luxembourg.

In a measure that will affect 450 employees, it said the decision was made in the light of weak demand in the Northern European construction sector.

“This is a temporary measure and the decision will be re-evaluated at the end of 2011,” ArcelorMittal said in a statement. “All measures will have an effect on 450 employees who will be put into the internal redeployment cell.”

At the Rodange and Schifflange site ArcelorMittal produces long carbon steel products including reinforcement bars, crane rails and special sections.

The steelmaker had announced in September that it would shut two blast furnaces in October, one at its plant in Eisenhuettenstadt, Germany, and one at its Florange plant in France, due to weaker steel demand in Europe.

In 2010, ArcelorMittal produced 92.629Mt of steel, of which 37% was produced in Western Europe and 11% in Central and Eastern Europe.
