Traditionally the steelworks of Belgium had been concentrated in the southern half of the country, in Wallonia, close to the historic coal mining areas at the edge of the Rhenish Massif; which in part defined the area that came to be known as the Sillon industriel including the regions of Liege and Hainaut.
