For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. Ikorwa cyane cyane nuburyo bukomeza bwo gusya, ni ukuvuga, icyuma kizungurutswe gihora cyinjizwa mu kigega cya plaque hamwe na zinc yashonga kugirango ikore icyuma gisya; icyuma gisize icyuma. Ubu bwoko bwicyuma nabwo bukorwa nuburyo bushyushye, ariko ako kanya nyuma yo kuva mu kigega, hashyuha kugeza kuri 500 ℃ kugirango habeho ibishishwa bya zinc na fer.
