Ishiti lensimbi elifakwe ngombala lisebenzisa i-galvanized steel sheet njengento esisiseko.Ukongeza kokukhuselwa kwe-zinc, i-organic coating kwi-layer ye-zinc nayo idlala indima yokugubungela kunye neyodwa, enokuthi ithintele ishidi lensimbi lingabikho kwaye linobomi obude benkonzo kunentsimbi yensimbi.Kuthiwa ubomi benkonzo ye-coated steel sheet bubude be-50% ngaphezu kwe-galvanized sheet.Izakhiwo okanye iiworkshops ezenziwe ngamashiti ensimbi anombala ngokuqhelekileyo zinobomi obude benkonzo xa zihlanjwa yimvula, ngaphandle koko ukusetyenziswa kwazo kuya kuchaphazeleka ngegesi yesulfure dioxide, ityuwa kunye nothuli.Ngoko ke, ekuyilweni, ukuba i-slope yephahla inkulu, akunakwenzeka ukuqokelela ukungcola njengothuli, kwaye ubomi benkonzo bude.Kwezo ndawo okanye iindawo ezingahlali zihlanjwa yimvula, kufuneka zihlanjwe rhoqo ngamanzi.
Nangona kunjalo, ubomi benkonzo yeepleyiti ezigqunywe ngombala ezinobungakanani obufanayo be-zinc plating, izinto ezifanayo zokugquma kunye nobukhulu obufanayo bokugquma buya kuhluka kakhulu kwiindawo ezahlukeneyo kunye neendawo ezahlukeneyo zokusetyenziswa.Ngokomzekelo, kwiindawo zoshishino okanye kwiindawo zonxweme, ngenxa yempembelelo yegesi ye-sulfure dioxide okanye ityuwa emoyeni, izinga lokubola liyanda kwaye ubomi benkonzo buchaphazeleka.Ngexesha lemvula, ukuba i-coat ifakwe emvula ixesha elide okanye ukuhluka kweqondo lokushisa phakathi kwemini nobusuku kukhulu kakhulu, i-condensation iya kwenzeka ngokulula, i-coating iya kugqwala ngokukhawuleza, kwaye ubomi benkonzo buya kufinyezwa.
