Hot-rolled coils are made into full hard coils by pickling to eliminate the oxide layer and then by continuous 

cold rolling. Continuous cold deformation causes cold hardening, and that results in the increase of strength 

and hardness, the decrease of tenacity and ductility and the worsening of impact resistance. Therefore, 

it can be used to make spare parts which need only a little deformation. Full hard coils can only be used as 

product material in hot-dip galvanizing plants, as hot-dip galvanizing sets are all equipped with annealing lines.
