#Pickling Line #Tandem Cold Mill (PLTCM): This mill reduces the thickness of the hot rolled coil to produce cold rolled coils.
Skin Pass Mill: This mill improves the surface finish of the cold rolled coils.
Bell Annealing Furnace: This furnace anneals the cold rolled coils to improve their #mechanical properties.
Hot Dip Galvanizing Line (HDGL): This line applies a zinc coating to the cold rolled coils to protect them from corrosion.
Coil Packaging Line: This line packages the finished products for shipment.
