Ukuze kuphuculwe ukuxhathisa kwe-corrosion, umbhobho wensimbi jikelele (umbhobho omnyama) ufakwe i-galvanized.Umbhobho wentsimbi owenziwe ngamachizayahlulwe ibe yidiphu eshushu eyenziwe ngegalvanized kunye neyombane yegalvanized iindidi ezimbini. Idiphu eshushu yokufaka igalvanizing layer kwaye ixabiso lokugalela umbane liphantsi, ngoko ke kukho imibhobho yentsimbi. Kule mihla, ngophuhliso lweshishini, imfuno yemibhobho yensimbi enesitayile iyanda.
Iimveliso zemibhobho yentsimbi enezitshizi ezishushu zisetyenzisiwe kwiindawo ezininzi, inzuzo ye-galvanized eshushu-dip kukuba ubomi bokuchasana nokubola bude. Isetyenziswa ngokubanzi kwinqaba yamandla, inqaba yokunxibelelana, umzila kaloliwe, ukhuseleko lwendlela, isibonda sokukhanya kwendlela, amacandelo aseLwandle, amacandelo esakhiwo sentsimbi, izibonelelo ezincedisayo kwi-substation, ishishini lokukhanya njalo njalo.
Hot dip galvanizing kukuba kuqala pickling umbhobho yentsimbi, ukuze ukususa oxide yentsimbi phezu komhlaba umbhobho wentsimbi, emva pickling, ngokusebenzisa ammonium chloride okanye zinc chloride isisombululo aqueous okanye ammonium chloride kunye nezinki chloride exutywe itanki isisombululo aqueous ukucoca, kwaye emva koko ungene kwitanki yokucoca idiphu eshushu. I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. Uninzi lweenkqubo ezisemantla zamkela inkqubo yokuzaliswa kwe-zinc yombhobho we-galvanized ibhanti ngqo.
Ubomi bemibhobho yentsimbi eshushu-diphu kwiindawo ezahlukeneyo azifani: iminyaka eyi-13 kwiindawo zoshishino ezinzima, iminyaka engama-50 elwandle, iminyaka eyi-104 kumahlomela-dolophu, kunye neminyaka engama-30 esixekweni.
