DESCRIPTION<br />
I. Heat Treatment Plant Building: Located parallel to and just<br />
west of the 22" Bar Mill Building, the Heat Treatment Building is<br />
634' long x 250* wide x 42' high. The riveted steel-framed,<br />
corrugated metal building was built upon a concrete foundation by<br />
the American Bridge Company. Its gabled roof and monitor are<br />
supported by riveted Fink trusses. The building is laid out in<br />
two directions. At the northern end of the building is a 90'<br />
wide transfer bay, extending in an east-west direction across the<br />
entire 250* width of the building. It houses a 30' high craneway<br />
which carries two 25-ton E.O.T. cranes. The cranes were used to<br />
transfer bars to one of nine heat treating furnaces which are<br />
laid out parallel to each other from east to west in the two<br />
production bays located just south of and adjacent to the<br />
transfer bay. Each production bay is 125 ! wide x 544' long and<br />
is serviced by two 25-ton E.O.T. cranes. The furnaces themselves<br />
each run in north-south direction.<br />
