Namhlanje, iibhobho zetsimbi ezinobumba zineentengiso ezinkulu zeemarike ngonyaka ngamnye kwimarike yensimbi. Ngokubhekiselele kwiteknoloji yokucubungula imveliso, umbhobho we-galvanized wahlulahlulwe kwiindidi ezimbini: umbhobho we-electro galvanized pipe kunye ne-hot dip gavanized pipe. Ebomini, abantu ngokuqhelekileyo basetyenziselwa ukubiza umbhobho otshisiweyo wamazinki oshushu njengombhobho ofakwe igalvanized. Xa sithetha nje, idiphu eshushu yombhobho ineenzuzo ezininzi zokusebenza kunombhobho we-electro galvanized. Ngaphandle koko, ngenxa yeendleko eziphezulu zokusetyenzwa, ixabiso lombhobho wensimbi libiza kakhulu kunombhobho we-electro galvanized. Njengomthetho, xa kuthelekiswa nombhobho wentsimbi oditshiweyo oshushu, umbhobho wentsimbi oxande awunayo ipropathi ilungileyo xa iyonke, ngakumbi ipropathi yokumelana nomhlwa. Kwiminyaka yakutshanje, ngenxa yomgaqo-nkqubo kazwelonke, ipayipi ye-electro galvanized isusiwe kwimarike yensimbi.
Xa kuziwa kumbhobho we-galvanized, kufuneka sazi malunga negama elithi "galvanization". Umbhobho wentsimbi etshiziweyo oshushu uya kuqhutywa apho kuya kwenziwa umaleko wengxubevange ejikeleze imibhobho ngenxa yokusabela komzimba phakathi kwezinki etyhidiweyo kunye nentsimbi. Ngenxa yoko, olu hlobo lombhobho lunamandla okumelana nokugqwala kunezinye iintlobo eziqhelekileyo. Ukongezelela, umbhobho wensimbi unombala ofanayo kakhulu kunye nepropati eqinile yokubambelela kwi-zinc layer ukwenzela ukwandisa kakhulu ubomi benkonzo yemibhobho. Ngaphezu koko, xa kuthelekiswa neminye imibhobho rhoqo, umbhobho eshushu dipped steel galvanized ineenzuzo ezininzi ezicacileyo kuluhlu olubanzi lweenjongo ngokwenene ebomini.
Ukuthetha ngobuchwephesha, i-galvanization inxulumene nokufaka i-zinc ekhuselayo yokukhusela kwintsimbi okanye umzimba wombhobho wentsimbi, ukuze uthintele ukurusa. I-galvanizing ediphini eshushu yeyona ndlela ixhaphakileyo yokwenza igalvanization, apho imizimba yemibhobho icwiliselwa kwibhafu ye-zinc etyhidiweyo. Ngokubanzi, ngokwezinto ezikrwada zemibhobho, umbhobho owenziwe igalvanized uneendidi ezimbini: umbhobho owenziwe ngaphambili kunye nombhobho oshushu oditshiweyo wentsimbi. Umbhobho owenziwe igalvanized ubhekiselele kumbhobho odityanisiweyo oye wathotywa, ukususwa kwerusi, ukuphosphorization, kunye neenkqubo zokomisa phambi kokufakwa kwegalati. Unyango ngaphambi kokuba i-galvanization ivumele imveliso ukuba ifakwe ngokufanelekileyo nge-zinc coating, kwaye iqinisekisa ukuba ubukhulu bengubo efanayo, ukunamathela okuqinileyo, kunye nokuphucula ukuxhathisa ukubola. Imibhobho ye-pre galvanized isetyenziswa ngokubanzi kubushushu, amanzi kunye negesi yendalo kwiinkqubo zobonelelo, intsimi yolwakhiwo lwe-greenhouse yezolimo, intsimi yolwakhiwo lwentsimbi kunye nenkqubo yemibhobho yoxinzelelo oluphantsi noluphakathi.
