Our Work Process

Cold rolled steel Process



Pickling Line

Use hydrochloric acid to remove iron oxide from the hot-rolled coil surfac andImproved surface management of high-carbon steels with brushes




Slitting Line (wide)

Cut large coils such as PO to rollingwidth and customer requirements



Rolled Mill

Cold rolled with the precision required by the customer. -Appropriate hardness and shape control for optimal machining.



Annealing

Improve machinability through elimination of internal stress of machined coils, re-determination of metal tissue, and globularization



Skinpass Mill

Remove yield point elongation and determine plate surface gloss



Slitting Line (narrow)

Cut to customer's required width and weight
