PPGIamapakidwa utotomalata chitsulo, yomwe imadziwikanso kuti chitsulo chophimbidwa kale, chitsulo chophimbidwa ndi koyilo, chitsulo chophimbidwa ndi mtundu etc., nthawi zambiri chimakhala ndi gawo lapansi lachitsulo chovimbidwa ndi zinki.
Mawuwa ndi chowonjezera cha GI chomwe ndi chidule chamwambo cha Galvanized Iron.Masiku ano, mawu akuti GI nthawi zambiri amatanthauza zinc (> 99%) yomwe imakhala yotentha mosalekeza, mosiyana ndi njira zoviika.PPGI imatanthawuza ku fakitale yopangidwa kale ndi zinki zitsulo zokutira, kumene zitsulo zimapaka utoto zisanapangidwe, kusiyana ndi kujambula positi komwe kumachitika pambuyo popanga.
Njira yopaka zitsulo zotentha imagwiritsidwanso ntchito popanga zitsulo ndi coil ndi zokutira za aluminiyamu, kapena zokutira za aloyi za zinki / aluminiyumu, zinki / chitsulo ndi zinki / aluminiyumu / magnesiamu zomwe zitha kukhala zopaka kale fakitale.Ngakhale kuti GI nthawi zina imagwiritsidwa ntchito ngati mawu ophatikiza zitsulo zosiyanasiyana zokutira zitsulo zotentha, imangotanthauza chitsulo chokuta zinki.Mofananamo, PPGI nthawi zina ingagwiritsidwe ntchito ngati liwu lachidziwitso chamitundu yambiri yazitsulo zokutira zomwe zidapentidwa kale, koma nthawi zambiri zimatanthawuza kwambiri chitsulo chopaka utoto cha zinki.
Zinc yokutidwa ndi chitsulo gawo lapansi la PPGI nthawi zambiri amapangidwa pamzere wopitilira galvanizing (CGL).CGL ingaphatikizepo chigawo chojambula pambuyo pa gawo la dip dip galvanizing, kapena nthawi zambiri zitsulo zokutidwa ndi zitsulo zamtundu wa koyilo zimakonzedwa pamzere wosiyana wopitilira utoto (CPL).Chitsulo chokutidwa ndi chitsulo chimatsukidwa, kuchitiridwa kale mankhwala, kuyikidwa ndi zigawo zosiyanasiyana za zokutira zomwe zimathautoto,vinylkubalalitsidwa, kapenalaminates.Njira yosalekeza yomwe imagwiritsidwa ntchito popaka zokutira izi nthawi zambiri imatchedwa Coil Coating.
Chitsulo chopangidwa mwanjira imeneyi ndi chopangidwa kale, chokonzedweratu komanso chokonzekera kukonzanso zinthu zomalizidwa kapena zigawo.kugwiritsa ntchito zinthu.
Njira yokutira koyilo ingagwiritsidwe ntchito pazinthu zina monga aluminiyamu, kapena aluminiyamu, chitsulo chosapanga dzimbiri kapena zitsulo zokhala ndi aloyi osati chitsulo "choyera" chokuta zinki.Komabe, chitsulo "choyera" chokhacho chimatchedwa zinki chomwe chimatchedwa PPGI.Mwachitsanzo, PPGL itha kugwiritsidwa ntchito popanga chitsulo chopaka utoto cha 55% Al/Zn (chitsulo chopaka kale GALVALUME)
