DAVY UNITED 500,000 TPY BAR AND SECTION MILL
Bar mill was commissioned in May 1968.
Stage 2 of the mill was commissioned in late 1973.
The mill was designed by Morgan Construction Co. of the USA and built by Davy United of England.
The mill hot –rolls billet into medium range Merchant bar for use in Engineering, Automotive, building
And Fabricating Industries and for export.
