Elevated view of the magnesium rolling mill and extrusion press (right-hand side of the photograph) at the Dow Chemical Company facilities located in Madison, Illinois. The 13-ton extrusion press, which was manufactured in Duisburg, Germany, measured 250 feet long and could produce extrusions up to 80 feet long. Dedicated in 1954, the magnesium fabrication plant in Madison was the world's first facility designed for the mass production of magnesium mill products and boasted the first large-scale magnesium sheet mill, as well as the largest extrusion facilities for the metal.
