Izvo zvigadzirwa zvekugadzirwa kweHot-rolled kana Cold-rolled Steel inogona kugadzirwa nechero maitiro.
Kupisa-yakakungurutswa Simbi: Muchigadziro chekugadzira, simbi inopisa inotanga kupiswa pakupisa kwepamusoro, ichibvumira simbi kuti iparadzwe muhurumende yepurasitiki, izvo zvinoita kuti zvive nyore kuchinja chimiro uye ukuru hwesimbi.Pakupera kwekupisa kunopisa, zvinhu zvinowanzoyerwa uye zvakakanganiswa.
Cold-Rolled Steel: Simbi inotonhora inoputirwa zvakare mushure mekunge zvinhu zvatonhora kuti zviwane saizi yaidiwa uye chimiro.Iyi nzira inowanzoitwa pakamuri yekupisa uye inoguma nesimbi ine nani pamusoro pemhando uye hukuru hwakanyanya.
Machubhu achagadzirwa neelectric-resistance-welded (ERW)process.
ERW pombi magadzirirwo ekugadzira weld nekukochekera zvinhu zvesimbi kuita humburumbira uye kuisa kuramba uye kumanikidza pakureba kwayo.
